The application of the roller crusher

Double toothed roller crusher is developed on the basis of traditional roller crusher and combined with the design concept of machine, electricity and oil integrated. It improved the crushing efficiency a lot and reduced the operation cost. Double toothed roll crusher crushing capacity is big, with limited distance between motor and reducer type hydraulic coupler, prevent dynamic overload, sensors, overload protection, safe and reliable. Hydraulic roller spacing adjustment, tooth roller bearing lubrication. Tooth profile optimization design, shear selection and broken, high efficiency low, the grain of uniform
Double Roll crushers are used for both, primary and secondary crushing. They guarantee a strictly defined final grain size with a minimum of fine grains. The roll crusher is applied in the industry of cement, chemical, electric power, metallurgy, building materials, refractories and other sectors for crushing medium hard materials such as medium and fine crushing of limestone, slag, coke, coal and other materials.It is more superior than ordinary crushers especially in the construction Materials Industry like pisolite and green bean shake production.   10-50 ton per hour Hydraulic Double Roll Crusher/Double Roller Coal Crusher/Stone Crusher Machine.

The design of the roller crusher is for customers' benefits:

1.With the advanced hydraulic control system, users can adjust the pressure according to the material hardness, so that can press and pulverize the materials absolutely.

2.With sensor, the machine can load relief when overload, so that to protect the machine.

3.The advanced hard faced technology improves the roller covers' life.

4.Good performance, low cost in operation and easily maintenance.
Working principle of double toothed roller crusher

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. Some major advantages.
