Double roller crusher, a kind of mining machinery, is also called double roller crusher. Mainly used for crushing ore. This machine has the advantages of small size, large crushing ratio (5-8), low noise, simple structure, and convenient maintenance. The crushed material has uniform particle size, low over-crushing rate, convenient maintenance, sensitive overload protection, safety and reliability. It is suitable for coal, metallurgy, mining, chemical, building materials and other industries. It is more suitable for the crushing of raw coal (including gangue) in large coal mines or coal preparation plants. The toothed roller crusher has a large crushing capacity,
The roller crusher appeared in 1806. It is a relatively old type of crusher. The roller crusher is also called the double roller crusher, the roller crusher, the roller crusher, and the roller crusher (double roller crusher). It is suitable for fine crushing operations where the feed size is less than 80mm and the finished product size requires 50 mesh-20mm. Such as the use of pebbles and construction waste for artificial sand; mining of finely crushed iron ore and quartz stone; ceramic industry crushing raw materials. It is suitable for coarse and intermediate crushing of brittle block materials in cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines and other industries. The feed size is large, the output size is adjustable, the crushing rate is low, and the maintenance is convenient. , Overload protection is sensitive, safe and reliable. It can crush materials with compressive strength ≤160MPa. Especially in the coal industry, the use of this machine to crush raw coal can be directly crushed after iron removal, impurity removal, and no gangue removal. The crushed material has uniform particle size and low crushing rate, which simplifies the coal preparation process and reduces Investment and production costs.
