1) The crushing chamber of a constant speed vertical axis impact machine can be either stone to iron or stone to stone. There is no qualitative change between the two, only a quantitative change. The former has a higher sand production than the latter, but the sand particle size is slightly worse, with a higher content of stone powder and more wear on the anvil. For the difference between stone to stone and stone to iron, please refer to 2 crushing methods and 2 feeding methods of sand making ma

With the depletion of natural sand resources in recent years, artificial sand has emerged in the market demand and its application has become increasingly widespread. Although artificial sand and gravel processing has a history of decades, how to choose the correct production process to ensure the reliable operation, advanced technology, and reasonable economy of the processing system is still an important problem faced by the design of artificial sand and gravel processing systems.

With the depletion of natural sand resources in recent years, artificial sand has emerged under the market demand and has been applied more and more widely. Although the artificial sand and stone material processing has several decades of history, but how to correctly select the production process to ensure the processing system reliable operation, advanced technology, economic and reasonable, it is still an important problem in the design of artificial sand processing system. This paper introdu

Dry mortar is a kind of granular or powdery mortar made by physical mixing of aggregates (such as quartz sand) , inorganic cementitious materials (such as cement) and additives (such as polymer) in a certain proportion after drying and sieving treatment, the material that can be used directly after mixing with water, which is also called mortar dry powder, dry mixed mortar and dry mixed powder, is a main direction of the development of building materials in the future. Depending on the use of dr

Sand machine in addition to normal maintenance, in winter low temperature, in order to ensure the normal work of the sand machine, need to pay attention to correct maintenance, equipment lubrication needs to be done in place. The volume of the Sand Machine and the capacity of the oil tank are not big, when the oil temperature is high, which requires good thermal stability and oxidation resistance of lubricating oil, but also have a good rust, corrosion resistance. Anti-emulsifying properties. In

In the current situation, with the vigorous promotion of infrastructure construction, the demand for sand and gravel aggregates is also increasing day by day. Many places have issued documents prohibiting sand mining activities in river channels, mainly because the speed of sand mining has exceeded its natural recovery rate. Therefore, many departments are vigorously promoting mechanism sand and providing policy support to solve the problem of difficult sand use. However, how to distinguish coar
