The series of double roller crusher is suitable for crushing raw materials with medium and low hardness, the Mohs hardness should not be bigger than 2.5. Distance between 2 rollers are 16-20 mm, can meet the requirement for medium crushing of the raw materials. The working speed of the roller can be adjusted by frequency conversion, and the crushing capacity can be adjusted as required.

Features and technology advantages of double roller crusher

1.Double rollers Can meet the requirements for crushing of materials; The use of hard alloy cutting heads on the roller teeth greatly improves their service life; Unique design has been carried out on the spindle structure of the rollers, fundamentally improving the reliability and service life of the entire equipment.

2.The pressure roller can make it easier for large pieces of material to enter the crushing roller, thereby improving the efficiency of the crusher

3. The wedge-shaped mud scraper can ensure the removal of materials stuck to the roller groove, improve crushing efficiency, and facilitate maintenance and replacement

4.The design of structure is tight, the wear-part is very seldom, and the maintenance is very easy.

Working principle of double roller crusher

This series of double roller crushers mainly consists of motors, reducers, hydraulic couplings, frame parts, mudguard parts, gearboxes, fast and slow rollers, pressure roller components and other parts. The two rollers of the roll crusher are moving towards each other for squeezing materials, the material is crushed between two rollers, and crushed product is discharged from bottom.
