Double tooth roller crusher is constructed by two toothed rollers which are driven by the motors and move in opposite directions. The materials fall between the two toothed rollers and are crushed into the required sizes by splitting, rubbing, bending and hitting. It is suitable for crushing brittle materials below medium and low hardness, such as bituminous coal, anthracite, lignite and coal gangue, also for sintered ore, coke, slag, shale and limestone, etc. Large-scale coal mines or coal-processing plants that want to crush raw coal (including gangue) can choose double tooth roller crusher.

 

Double roller crusher squeezes and grinds materials by its two smooth rollers which move in opposite directions. It specializes in crushing various ores and rocks below high and medium hardness, especially for pea gravel and other materials used in the building industry, which have more excellent performance than general crushing machinery.

 

Advantages of double tooth roller crusher

1. The toothed plate of crusher is made of alloy material with high wear-resistant strength, which greatly extends its service life.
2. Compared with the old crusher, its improved tooth height and tooth spacing greatly enhance the crushing performance.
3. The baffle is added on the bin feeder to solve the problem that the materials are evenly distributed on the rollers.
4. The spindle cast by quenching technology enjoys improved strength, rigidity and wear resistance.

Advantages of double roller crusher

1. Double roller crusher consists of one fixed and one movable rollers rotating synchronously in opposite direction.
2. The materials is continuously brought between the two rollers by the extruding rolls, and then discharged from the bottom of crusher with the ideal sizes after being processed with high-pressure 50-200MPa.
3. Once the material is squeezed by the rollers, the pressure between the rollers will gradually increase up to 200Mpa. For its discharged materials, in addition to a certain proportion of powdered materials, the rest of the granular materials feature a large number of cracks inside, which will greatly decrease the energy consumption in the further grinding.
