Even in some cement production enterprises, people blend fly ash, in accordance with the ratio of 8%, into different cement clinkers to make cement products.


What Determines the Fineness of Artificial Sand?

As a kind of local resources, natural sand belongs to a nonrenewable resource in a short period of time. At the same time, with the fast and continuous development of the infrastructure development, the phenomena constant decrease of natural sand resource, reduction of sand quality and limit or prohibition of exploitation of natural sand show up in many places in our country, which injects huge potential and vigor for the artificial sand market.

Because the reserve of pebble in our country is very rich, and as one of the pure natural stone materials, the pebble has natural property of hard texture, pressure resistant and friction and corrosion resistant, making use of the pebble in order to produce artificial sand is the best choice for satisfying the construction sand. Attracted by this opportunity, many companies begin to pitch into the pebble sand making production process.

With the constant expansion of the market demands, all kinds of sand making devices begin to be manufactured like the mushrooms after rain, but the quality of the equipment is not improved with the amount of the machines in the market. During the construction projects process, a lot of problems resulted by the quality of the sand and stone begin to show up, for example, a lot of gaps are left between the concrete which is resulted by the rough surface of the sand and stone and the not round shape. For this reason, to ensure the fineness of the artificial sand has profound significance to the building sand.

Then, the question is what determines the fineness of the artificial sand. The professional, famous and leading crusher manufacturer in our country Hongxing Machinery thinks that the most important factor that determines the fineness of the artificial sand is the production equipment.ore beneficiation:http://www.hx-china.com/36.html

Study on Automatic Control of Rotary Kiln

Rotary kiln is a large sized thermal machine with the advantages such as high quality of roasting and products so that it plays an important role in many industrial departments such as chemistry, metallurgy and mining. However, this equipment belongs to those kinds of devices that have very high energy consumption in our country. Especially inside the small and medium companies, the automatic level of the production process of the rotary kiln is very low, so that the whole working process of the equipment should be in a high energy consumption station for a very long period of time which will definitely aggravate the tension of the energy resources in our country.

Some large sized mining companies in our country also did some meaning practice in the automatic control aspect of the rotary kiln, mainly by way of examining the thermo technical signals inside the kiln such as temperature, pressure and flow amount of the slurry, on the basis of which, keep the temperature of the burning area in a allowable range with the method of intelligent control. However, because of the limit of the examining means, when designing such control systems, the experts often forget the important information of the moving state of the materials inside the kiln. As a matter of fact, the moving state of the materials has a decisive effect on the energy transmission process of the kiln.

The materials inside the industrial rotary kiln such as aluminum oxide rotary kiln and limestone roasting rotary kiln is mainly in a slumping moving state, and the angle of repose is important information describing its movement features. We simulate the cross section of the rotary kiln with a solid of revolution and adopt the computer image processing technology to follow the sliding process of the materials, and measure the changing relationship of the angle of repose of the materials with time in an offline state and finally get the changing range of the angle of repose. On the basis of which, we analyze the relationship of the avalanche time which is an important parameter that influences the heat transfer process of the kiln and the materials compactness. According to the experiment result, we make a comparison and data validation to the existing Slumping Theoretical model and it shows that the model proposed by Mellmann has a relatively higher precision.ore beneficiation:http://www.crusher-machine.com/n51.html
ball mills:http://www.hx-crushers.com/p72.html

At present, there is still no report on the research of computer online examination of the angle of repose of the materials inside the industrial rotary kiln. Aiming at the characteristics of the complicated image area and low noises of the materials in the kiln, experts of Hongxing Machinery put forward a measurement method of the angle repose of the materials based on the image processing technology. By way of a series of process such as collecting, mean value cluster segmentation of the vague C, fringe collecting and least squares fitting a straight line of the original image of the kiln, we get the angle of repose. In order to validate the feasibility of this method, we did a Matlab computer simulation to the image alignment of an aluminum oxide rotary kiln and get a dynamic curve of the angle of repose with the change of time and the cycle feature of the curve correctly reflects the movement state of the materials inside the kiln.

Henan Hongxing Mining Machinery Co., Ltd is a large-sized sand maker manufacturer, and our sand maker has many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price.


Hongxing Unique Grinder with three Rollers

A grinding mill is a unit operation designed to break a solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. Historically mills were powered by hand (mortar and pestle), working animal (horse mill), wind (windmill) or water (watermill). Today they are also powered by electricity. Hongxing Machinery is a professional roller grinding mill manufacturer, and supplies various kinds of roller mill and dryer machine, which all adopt national advanced technology and have high efficiency with low cost.

Designed for continuous operation, the grinding mill with three roller performs efficient fine grinding and classification of soft to medium-hard materials. Due to the integrated bearing system of roller table, three roller grinding mill does not need any reinforcement on gearbox itself and requires minimal maintenance.

The grinding operation of three roller grinding mill is performed on the principal of Attrition and compression, which results due to the centrifugal force generated from the suspended rollers running inside a stationary Bull Ring. The material to be grind enters the grinding chamber through an automatic feeder and falls on the mills floor. There it is scooped up by steel into the nip space between the rollers and Bull Ring where grinding takes place.

The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.Dryer machine:http://www.hxjqchina.com/product-list_35.html
ore beneficiation:http://www.crusher-machine.com/n51.html

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world"s power (see List of countries by electricity consumption).

The classifier separates grinded materials, and coarse particles return to grinding chamber for further size reduction. Fine materials are carried by air to the cyclone air separators where air and grinded material are separated and collected. The clean air is returned to the blower for close circuit operation.

A constant quantity of air is circulated through the mills and system. The air from blower enters the mills through a series of tangential ports round the bases of grinding chamber and sweeps the fine and medium fine material to the classifier above the grinding chamber leaving no grinded material in the chamber and allowing the rollers to work & efficiently crushing coarse material.


Choosing Right Hammer Crusher Brand is Paramount

At present, many leaders of the stone and sand plant and small and medium cement factories often complain that the economic situation in recent years makes the cement and stone and sand industry not hot as before and the profit margins of this industry has been shrinking continuously. On the other hand, the hammer crusher which is one of the crushing equipment that is often used in the cement and stone and sand making process cannot make people feel relieved as well because the investment cost is extremely high and the operational and maintenance cost in the latter period is also very high. Then during the operational process of the hammer crusher, what problems will occur? And how can the customers chose the right hammer crusher brand?

Hammer Crusher is mainly used for crushing medium-hard or brittle materials with hardness not more than 300Mpa and 15% moisture such as barite, limestone, terrazzo, silica sand stone, coal, coke, gypsum, aluminum sulfate, slag, salt, chalk, blocks, cement, alumen, brick, tile, etc. It has the features of simple structure, big crushing ratio, high production efficiency, uniform particle size, etc. The hammer crusher is one of the main equipment for intermediate and fine crushing the brittle materials with less than intermediate such as limestone coal and other used in metallurgy, building material, chemical and water - power industry, with a feature of big crushing ratio and even product graininess.

The wear resistant part of the hammer crusher has a serious influence on the performance of the crusher equipment. The hammer of the crushing machine will produce severe impact and friction with high rotating speed during the crushing and breaking process, for this reason, the hammer may be wore and tore in a very short of time and will be discarded as useless which lead to the working efficiency of hammer crusher decrease extremely and the energy and electricity consumption increase significantly which seriously influenced the overall use performance of the hammer crusher. This resulted great damage to the cement and stone and sand companies every year and at the same time, frequently changing the hammer also make the working conditions of the workers become worse and bring with it many unsafe production factors.impact crusher:http://www.hxjq-crusher.com/2.html
raymond mill:http://www.hx-crushers.com/p54.html

When the customers choose the hammer crusher brand, they should take the wear resisting property of the hammer and choose professional wear resistant part manufacturer. In this way, the professional company will ensure the excellent and long service life of the crushing equipment, and on the other hand, avoid the influences of the performance reduction of the hammer crusher resulted by the quality problem of the wear resistant part, and at the same time, greatly reduce the operational and maintenance cost and reduced the working pressure of the workers.

Our company has been adhering to the concept of "people-oriented, customer supremacy, development and innovation".

Mining Equipment Has Huge Demand in 2011

Global demand for specialized mining machinery and equipment such as dryer machine (including separately sold parts and attachments) is projected to increase 5.9 percent per year through 2011 to $33.6 billion. Advances will be fueled by continued demand for commodities such as iron ore and copper. In addition, the ongoing global thirst for energy will boost global coal output. China and India will be leading sources of mining equipment demand for ore beneficiation machines. However, just as importantly, these nations will continue to fuel demand for mined products throughout the world, thereby providing opportunities for machinery producers. These and other trends are presented in World Mining Equipment, a new study from The Freedonia Group, Inc., a Cleveland-based industry research firm.

China has shown strong growth in mining equipment demand, a direct result of investment in its local mining industry. For example, coal output nearly doubled from 2001 to 2006, reflecting the nation’s intense need for energy. China is also a major source of commodities such as iron ore and bauxite. Other major Asia/Pacific markets for mining equipment include Australia and India. Like China, India has experienced major growth in coal output in recent years. Australia, a leading producer of bauxite and iron ore, is a major source of commodities for its developing Asian neighbors.

Demand for mining equipment in Asia is expected to post strong gains, as region’s rising population and industrial output will lead to increased energy and raw material needs. Africa will post healthy gains, benefitting from rising demand for precious metals and copper. Growth in demand for mining equipment in Latin America will reflect increased mining investment in nations like Peru and Chile. Eastern Europe will also post gains, benefitting from gains in the large Russian market.jaw crusher:http://www.hx-china.com/1.html
jaw crusher:http://www.hx-crusher.com/stone_crusher.html

Growth in North America and Western Europe will lag the industry average, reflecting the maturity of these markets. However, the largest producers of mining equipment are generally found in the United States and the industrialized nations of Western Europe. Such countries have a long history and extensive expertise in the development of capital equipment industries of all types, which many have leveraged in mining machinery. China has quickly emerged as a major producer, due in large part to the nation’s growing mining industry. China has become a net exporter of mining equipment, shipping products to both developing nations and mature markets such as the US.

The market for mining machinery used in metals mining operations, which account for the largest share of world sales, is projected to expand at the strongest pace through 2015, spurred by price-driven increases in resource exploration and mine development activity. Coal mining equipment demand is expected to climb nearly as fast, stimulated by an acceleration in primary metals manufacturing growth, bolstering industrial furnace and oven coal use. The world market for non-metallic minerals mining machinery will rise at a somewhat slower rate, stimulated by increases in construction expenditures and ongoing population growth, boosting farming activity and consumption of fertiliser minerals like phosphate rock and potash.


What is Core Device in Sand Production?

HX series sand maker is a high-efficiency rock crushing equipment with home and international leading level; the machine is developed by introducing the crushing theory and technology from Barmac Company of America and combining the actual situation of sand making. It is widely used for crushing of hard and brittle materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate; and it is especially suitable for the sand and sandstone making for construction and road paving.

HX-series vertical shaft impact crusher, also called sand making machine and rubble shaping machine, is a kind of crusher impacted by the materials themselves. The materials fall into the hopper, be thrown to the impellers which are rotating at a high speed. Then the materials are accelerated and thrown out of impeller area, impacting the materials distributed around the impeller by the effect of centrifugal force. After impacting with each other, the materials are crushed between impeller and cabinet, bumped and rubbed to each other again and again. They cycles many times with the close circuit and the vibrating screen will control the granularity of finished products. At last, the crushed materials will be outputted from the discharging opening.

The mineral crushing enterprise has higher requirements of ore pieces in recent years. Of course, quality requirements for using crusher also should be improved. Because only the high-tech, high performance crusher can produce first-class mineral stone, at the same time, also can reduce the cost of enterprise. For the choice of crusher, a large part of shattered enterprise choose to use sand making machine, so the sand making machine is the core equipment of artificial sand.raymond mill:http://www.hxjqchina.com/product-list_22.html
rotary kiln:http://www.hxjq-crusher.com/23.html

Along with the continued growth of economic, sand making machine has become the important symbol of the equipment in the coal. Sand making machine is widely used in metallurgy, mining and other industries. We need to use the high quality and high efficiency of equipment to meet needs of the sand in engineering construction projects. We need the sand aggregate all the time in the construction, but because of excessive protection, the natural sand mining is protected. Gradually artificial sand become the first demand of the construction and is better than the natural sand more with the standard of sand, so sand making machine also became known as the core equipment of the mechanical system. But sand technology of our system is worse than the advanced foreign technology, so we have to try to shorten the gap between us.

The sand making machine produced by Hongxing Machinery is applied in highway, high-speed railway, high-rise buildings, water conservancy and bridges, concrete mixing stations with the most high-quality for these projects and aggregate, and become the core equipment of artificial system sand production field. Sand making machine is the more and more important mainstream equipment for metal ore broken, quartz sand production, steel slag processing and other areas.

To meet the trend of modernization development and the needs of international markets competition, our company has been introducing senior management personnel, scientific and research talents, and advanced graduates continually. And we are taking advantages of advanced technology from United States, Germany, Japan and other countries to achieve self-innovation and effective development.


Affecting Elements of the Crusher Price

In the past few years, "inflation of prices" has become a rather troublesome problem. The price of the products of each industry was affected by different factors, and all we are looking for both of affordable and quality reliable products in wide variety of industries including mining machinery. With more and more crusher enterprise emerge in large numbers, a number of small businesses fighting a low-price strategy in order to capture the market with cheap inferior products. So when finding the crusher manufacturers, you must carefully consider the factor details about the market and industry, which is prerequisite for you to purchase quality products.As a professional mining hammer crusher manufacturer, Henan Hongxing Mining Mahinery Co., Ltd doesn"t fear of price competition. We believe that good quality is the products" natural value.

First of all, the main factors affecting the price of crusher is the high price of produces material. As is well-known, the best produces material of crusher is steel, so domestic steel prices will directly affect the price of crusher. If the domestic price of steel in the rising phase, crusher prices are also rising in the same way. Here, buyers must be careful price trap offered by the production equipment enterprises. If offered price was significantly lower than the average market price,it certainly indicated the device is unqualified,as no company will do the trading losses.

Second, with the same manufacturing cost, the size of crusher specifications and production parameters also affect the price. Purchase according to the needs of production equipment specifications, so as not to waste of money. Learn more about the price of several manufacturers if different names equipments are of the same specifications, so that you will not be deception of the irregular vendors.ball mill:http://www.hx-china.com/14.html
rotary kiln:http://www.crusher-machine.com/28.html

The finally influencing factor of crushers" price, of course is technical standard.Amounts of technical content certainly match the high sales price. Purchasing enterprise must understand the various technical parameters of the equipment. For example the same appearance equipment, some can be used for three years and some can be used for five years. How to choose it? Answer is that we would rather spend little more money to buy the more qualified and reliable equipment.

Our company has been adhering to the concept of "people-oriented, customer supremacy, development and innovation". We are able to provide our customers not only the highest quality products at the most favorable price, but also the most reasonable suggestion of equipments, optimum process configuration, and a full range of technical support.
