The crushing & grinding of materials is a process widely used in metallurgy, mining, building materials, chemical, electric power and other industrial sectors. A large number of raw materials and reused wastes need to be crushed every year.

In the mineral processing industry, the crushing of materials occupies an important position. The production cost of crushing and grinding operations in the beneficiation plant, on average, accounts for more than 40% of the total beneficiation production cost, and the investment in crushing and grinding equipment accounts for about 60% of the total investment in the beneficiation plant.

In the cement industry, the cost of crushing and grinding operations in cement plants accounts for more than 30% of the production cost, the power consumption of crushing machinery accounts for about 10% of the total power consumption of the whole plant, and the power consumption of grinding machinery accounts for 60% .

According to reports, about 15% of the world’s electrical energy consumption is used for pulverization, and it is increasing year by year, of which more than 85% is used for grinding. With the increase in lean mines, the increasing demand for building materials, the increasing proportion of recycled materials accumulated by industrial use, and the shortage of energy, there is an urgent need to continuously improve the grinding operation, such as the use of “more crushing and less grinding” technology, especially The development of high-efficiency crushing equipment and the improvement of existing crushing and grinding machinery are of great significance for achieving high-quality, high-yield, low-cost, and low-energy consumption.
