The commonly seen roller crusher falls into three types: single roll crusher, double roll crusher and four roll crusher. In the working process, material falls in between the two rollers, and will be crushed. Normally, the material will be discharged from the bottom.
When encountering material with high hardness, the rollers will automatically concede by hydraulic cylinder or spring which will increase the space between the two rollers, resulting in the falling of material with high hardness and uncrushable material, to protect the machine from damage. Changing the space between the two rollers can definitely control the maximum particle size of discharged material.
The double roll crusher can be applied in industrial sectors, such as cement industry, chemical industry and building materials industry for medium and fine crushing of material with medium and high hardness like limestone, coke, coal, etc. Double roll crusher features a two roll structure with smooth surface
Teeth roll crusher is available in two roll and four roll series. According to the characteristics of material, coarse and fine teeth can be chosen. Four roll type teeth crusher is actually made up of two double roll teeth crushers.
Teeth roll crusher is outstanding for its large crushing capacity. In addition, the hydraulic coupling with limited distance connecting the motor and reducer prevents overload and the overload protection sensor device makes the machine safe and reliable. The hydraulic adjustment of tooth roller space and central lubrication of tooth roll bearing are additional advantages. The optimization design of tooth shape and selective crushing make roll crusher a machine with high efficiency and low energy consumption and uniform granularity
A roll crusher crushers using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.Our double-toothed roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production
