strengthening publicity of the development of circular economy, adherence to development and saving, saving priority, in accordance with reduction, reuse, resource system, and gradually establish resources of the whole society in terms of resource mining, production consumption, waste, consumption, etc. circular utilization system to save energy, saving water, saving land, saving materials, and strengthening promoting saving, strengthening comprehensive utilization of resources.
[Abstract] :
Strengthen the publicity of the development of circular economy, attach equal importance to development and conservation, give priority to conservation, follow the principles of reduction, reuse and resource recovery, in the exploitation of resources, production and consumption, waste generation, consumption and other links, To gradually and comprehensively establish the resource recycling system of the whole society, it is necessary to save energy, water, land, materials, strengthen the promotion of saving, strengthen the comprehensive utilization of resources and other policies.
【summary】:
it is understood that in our country's non-metallic mineral products, the development and utilization of their development began in the 1950s, so far, there is more than 100 kinds of non-metallic minerals that have been discovered by the economic value, which greatly promotes the speed of the economy. developing. because of the discovery of non-metallic minerals, the mineral operation has become a major operation, so that the non-metallic mine ultrafine pulverized operation is constantly being strengthened, and the requirements for mineralization and crushing machinery and equipment are increasing. most of the non-metallic mines are directly used in agriculture, chemical, paper, rubber, coating and more after the crusher is crushed. non-metallic minerals, according to non-metallic minerals
[Abstract] :
It is understood that the development and utilization of non-metallic minerals in our country began in the 1950s. So far, more than 100 kinds of non-metallic minerals with economic value have been discovered, greatly promoting the rapid development of economy. Because of the discovery of non-metallic minerals, mineral processing has become a major operation, so that the ultra-fine grinding of non-metallic ores has been strengthened, and the requirements for mineral processing and crushing machinery and equipment are becoming higher and higher. Most of non-metallic ore is crushed and classified by crusher and directly used in agriculture, chemical industry, paper making, rubber, coating and other products. There are many kinds of non-metallic minerals according to the non-metallic minerals

on the one hand, the crusher is also divided into thickness and detailed, from another angle, can also be divided into a jaw machine, hammer crusher, counterattack crusher, impact crusher, composite crusher, roll crusher, etc. . the different principles of the machine's work design leads to the degree of crushing and force of the material during operation, and the crushing method is different.
[Abstract] :
On the one hand, crusher is also divided into coarse and fine broken, from another Angle, can also be divided into jaw crusher, hammer crusher, impact crusher, impact crusher, compound crusher, roll crusher, etc.. The different working design principles of the machine lead to the crushing degree and force of materials during operation, and the corresponding crushing methods are different.
【summary】:
the rotary crusher is a large-scale rotary crushing of the material to generate extrusion, splitting and bending of the material using the cadrograph in the cone in the casing, and a large-scale rotary crushing machine for extrusion, cleavage, and bending, ore or rocks of various hardness. the spindle is equipped with a broken cone, the upper end of the spindle is supported in the bushing in the middle of the cross member, and the lower end is placed in the eccentric bore of the shaft sleeve.
[Abstract] :
Gyratory crusher is a large gyratory crushing machine which uses the cyclic movement of crushing cone in the cone cavity of shell to produce extrusion, splitting and bending effect on the material and coarse crushing of ores or rocks of various hardness. The spindle is provided with a broken cone, the upper end of the spindle is supported in the middle of the beam bushing, and the lower end is placed in the eccentric hole of the shaft sleeve.
【summary】:
in recent years, with the development of my country's crusher industry, on the one hand, the market size is increasing, on the other hand, the basic construction is constantly strengthened, and it has also continued to put forward new and higher requirements for crushers, except for technology and intelligence. it also reflects the energy saving reduction and green environmental protection. there is no doubt that twelve five is a critical period of my country's economic growth and transformation. steel slag mainly derived from the oxide formed after the oxidation of the elements contained in the scrap steel, the impurities brought by the metal furnace, such as fluorite, limestone,
[Abstract] :
In recent years, with the development of crusher industry in China, on the one hand, the market size is expanding day by day, on the other hand, the strength of infrastructure construction is constantly strengthened, but also constantly put forward new and higher requirements for crusher, in addition to technology and intelligence, but also reflected in energy saving, consumption reduction and green environmental protection. There is no doubt that the 12th Five-Year plan is a key period for China's economic growth and transformation. The society pays special attention to how to realize the transformation of production mode through the development of iron and steel waste disposal. Steel slag mainly comes from oxide formed after oxidation of elements contained in molten iron and scrap steel, impurities brought by metal charge, slagging agent such as fluorite, limestone,
