A double plain-roller crusher refers to a type of crusher with two parallel, oppositely rotating rollers that operate independently without any teeth or protrusions on the surface. This design is different from those with toothed rollers, as it relies on the smooth surfaces of the rollers for the crushing action.
Medium and fine crushing of non-metallic brittle materials in steel, electric power, mineral processing, chemical, cement, building materials and other industries, especially suitable for raw coal, coke, ore, rock and other materials with a hardness of 50-80MPa.
The technology guarantees a high crushing ratio and a low powder rate. It creates a 6000-hour super wear-resistant smooth roller.
The frame and the cabinet are box-shaped welded quick-release structures, which reduce equipment maintenance costs.
The mechanical spring structure ensures proper crushing pressure between the rollers.And has a concession protection function.
2PGM series of double roller crusher has dual rollers rotated in the opposite directions. Mine ore enters into the crushing cavity between two rollers by the force of friction force to be broken by pressing. Crushed products are discharged from the space between two rollers by the self-gravity. The min. distance between two rollers is the width of discharging port that decides the largest particle size of crushed products. This type of machine is a domestic newly developed crusher which is based on the previous mature type 2PG double roller crusher. It is applicable for the intermediate and fine crushing of 50-80MPa nonmetal brittleness materials in the industries of steel, power, mine selection, chemical industry and cement and building materials, especially the materials below hardness of 50-80Mpa coal, coke, ore and stone.
2PGYQ powerful double roller crusher is a new developed type of double roller crusher which absorbs and learns from the high-pressure grinding roller crusher and 2PGY double roller crusher and adopts hydraulic cylinder to improve pressure. It is suitable for non-metal materials with its crushing compressive strength no more than 140 MPa, which is widely used in steel, non-ferrous metals, power plant, chemical industry and building material industry, especially for sintering plant and carbon factory.
