Product Description
Double roller crusher is suitable for crushing sticky and wet material in addition to the regular primary and secondary crushing of soft and semi hard particles. The machine is mainly used for primary crushing in open pit mining (ROM) as well as for further crushing stages. They are particularly used for primary crushing in open pit mining (ROM) as well as further crushing (2nd + 3rd crushing stage). Feed material which can used in the machine are lignite, coal, soft to medium-hard rock, different types of ore, chalk, gypsum, limestone, marl, clay, bauxite, different types of phosphates, oil sand and overburden.

Components of double roller crusher:
1. Hand pump for safe, easy hydraulic adjustment of crushing rolls
2. Relief springs on each side that adjust for maximum protection from tramp metal damage
3. Driven rolls that feature a V-belt and spur gear system for easier maintenance
4. Spur gears of case hardened 4140 steel that allow 0'' to 6'' adjustment between crushing rolls
5. Crushing rolls use replaceable segments bolted together for easy maintenance
6. Sealed bearings in dust-tight pillow blocks for longer life
7. Ribbed housings of heavy plate steel reinforced at stress points
8. Replaceable liners throughout for maximum ease of maintenance

Features of double roller crusher:
1. The product can be classified into double roller crusher and four roller crusher according to the roller quality.
2. The products are widely used in grinding cement, metallurgy, chemical, power generation, coal and other fragile stuffs.
3. It has compact structure, light weight and small size. As for the powder grinding system with the same production capacity requirement, the equipment of the teeth roll crusher can significantly save the investment.
4. It has simple structure, and takes up smaller space, and the operation and maintenance of this machine is very convenient.
5. There is equipped dust-proof plant inside the machine and the sealing ability is excellent, so that there is little powder dust and lower working noises, so that the working environment is greatly improved.
6. The roll is optimized designed, and the equipment does not need to change the roll.
7. There is changeable anti-abrasion lining board which adopts advanced anti-abrasion materials, so that it has many advantages such as long service life and convenient maintenance.
8. This double roll crusher is equipped with safety protection device.
9. The gap of the roll can be adjusted according to the requirement of the customers.
10. Double roller crusher with stable operation, easy maintenance, low cost, output size adjustable.

Working principles of double roller crusher:
The roll crusher uses compression, with two rolls rotating around a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product required, with the realization that the largest feeding 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.
