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

As the saying goes, the harder a person falls, the higher their future rebound will be. This principle also applies to the field of construction machinery.Last year, the overall index of the construction machinery sector was at its lowest level in recent years, and in May, it reached its darkest hour. Under the favorable conditions of the opening up of the epidemic this year and the stimulation of multiple economic policies, construction machinery has returned to the perspective of investors.So

Culture is the soul of a country, a nation, and even an industry. In the thousands of years of civilization development in China, mining development has accompanied closely, creating rich and brilliant mining culture, and for a considerable period of time, it has been at the forefront of the world, becoming an important driving force for the development of human civilization, and becoming a brilliant, brilliant, and remarkable chapter in the history of Chinese civilization.Strengthening cultural
