Most of the waste in construction waste can be reused as recyclable resources, such as waste steel bars, scrap iron wire, scrap wire, and scrap metal parts, after being sorted, removed, or crushed by a crusher. After re-melting, it can be processed into various specifications of steel; waste bamboo can be used to manufacture artificial wood; bricks, stones, concrete and other waste after crushing by the crusher, can be used for masonry mortar, wipe Grey mortar, playing concrete cushions, etc., can also be used to make building materials such as blocks, pavement tiles, and flower tiles.

There are also a large number of spoils and discarded materials for urban demolition, urban village reconstruction, new rural construction, and residential decoration. These are all construction wastes. At present, the standards for comprehensive utilization of construction waste crusher are being researched and developed. Recycling will become the main method for the city’s construction wastes to be contained. Building landfills will not only occupy scarce land, but will also be a great waste of resources. The construction waste treatment and crushing and screening equipment developed by Henan SBM Industrial Co., Ltd. can process construction waste into standard bricks and ancient bricks, and can also produce coarse aggregates of recycled concrete. After dust is precipitated, it can also be used as an organic filler for road construction. . It not only protects the environment but also complies with national standards.

The crushing and screening industry has accelerated its growth, and crushing and screening equipment dominates the rivers and lakes. In January and February 2010, the output value of the crushing and screening equipment and the growth rate of value added not only continued to accelerate growth, but also set a record high, indicating that domestic crushing and screening equipment showed a high degree of prosperity in the first quarter, and revenue and net profit were expected to increase substantially.

Due to the recycling of construction waste, construction waste resources are recovered to the maximum extent, and problems such as occupied land area and air pollution are effectively prevented, and clean production and recycling development are realized. SBM Industrial's construction waste processing equipment crushing, sand making, grinding three series of dozens of models of products, and widely used in mining, metallurgy, building materials, coal, refractory materials, ceramics and other industries. On the basis of absorbing advanced technologies at home and abroad, we have optimized the design and manufacture of crushing and screening equipment with hard rock counter-attack crusher, jaw crusher and sand making machine as the core, becoming a domestic and international construction industry and high-grade railways. , highway pillar equipment.

Dolomite is a kind of carbonate mineral that is the main mineral that makes up dolomite. Dolomite with high purity appears white. If doped with iron impurities, it will appear gray. When it is weathered, it will appear brown. Dolomite has glass. Shiny, granular, has now become an important industrial raw material. Bulk dolomite can not meet the needs of the materials used in various fields of production. The dolomite required in various production fields is a powdered dolomite powder, so dolomite Raymond Mill is used to crush large blocks of dolomite. Milling processing.

For users who want to invest in the field of dolomite milling, they must first understand the application of dolomite powder. With the development of economy and the advancement of science and technology, the application of dolomite powder is gradually broadening. It is certain that the The dolomite sold in Mongolian processing is very good and has a promising future. At present, dolomite has been widely used in the fields of refractory materials, chemical engineering, glass, building materials, etc. In the field of refractory materials, dolomite can be used as basic refractory material, and can also be used as a solvent for blast furnace ironmaking to effectively improve the quality of smelting and can be used as a production glass. , ceramic ingredients, etc., application is very wide.

Users do not have to worry about the dolomite market problem. The most attention should be paid to the purchase of dolomite Raymond Mill because there are many manufacturers of dolomite mills on the market and many Dolomite Raymond Mills are facing the market. The user must keep their eyes open and select carefully. The main purchase procedure is as follows: Determine the model - shop around - Determine the alternative manufacturers - Visit the factory - Determine the cooperation manufacturer, the user in the process of purchasing Dolomite Raymond Mill, except To compare the quality of equipment manufacturers, prices, after-sales manufacturers and other issues, but also pay special attention to the credibility of the manufacturers, the size of the manufacturers, the manufacturer's delivery speed and the location of the manufacturers address, consider carefully to buy more suitable dolomite Raymond Mill.

When ore and other materials are ground more finely, they can make production more efficient, save a lot of costs, and make tailings recycling easier. The fineness of milled ore discharge products discussed here generally refers to P80 grain sizes of 20 μm and 7 μm, which need to be produced in energy cost and low-cost mill production lines. If this fineness is to be achieved, in the selection of production line equipment, superfine pulverizers are selected as the main grinding equipment, and the electric energy required for the dissociation of ore pellets accounts for about 70% of the total cost of the concentrator. When the conventional milling equipment is used to grind minerals to below 20 20 μm, the cost of traditional Ultrafine mill increases exponentially with the reduction of grinding fineness.

The second problem with fine grinding of minerals with a conventional grinding machine is that its rotational speed is relatively low, because when the rotational speed of the mill is higher than the critical rotational speed, the grinding medium is rotated by the centrifugal force and rotates with the cylinder. The power of the low speed mill is relatively low. Low, in fine grinding, low-power-strength mills can not meet the high grinding ore processing capacity required by the mineral industry, and equipment must be added, which in turn increases production costs. In order to effectively solve these problems, the traditional mill needs The use of steel balls with a diameter greater than 20mm, and such a large steel ball gap is large, is too large for the grinding fineness of particles smaller than 2020μm, the impact and grinding pressure generated by the magic ball can not form a fine crushing effect on smaller materials, It increases the wear rate of the magic ball, making the production line produce a large number of substandard products. Therefore, in the face of demanding production requirements, traditional mills have become increasingly incapable of producing production contradictions.

Based on this, the birth of a new type of superfine pulverizer brings light to ultra-fine crushed mineral materials. It has two fixed grinding chambers, uses small grinding media, and uses two sets of high-speed rotating stirrers in the mill. Operation, stirring mill relies on high-intensity stirring effect, effectively drives small grinding media to rotate at high speed, forming a lot of compressed rotating media layer, this media layer can produce many surface pressure and torsional force, making the material crushed to the right size. Tested and actually put into operation, the effect is very significant, and it is a classic of the new grinding equipment.
