Roller Crusher

PYM's roller crusher is traditional double roller crusher, due to the structure of the crusher, it is quite suitable to produce the sand below 10mm.

Input size:  0-25mm
Capacity: 20-100tph
Material:   iron ore, cement clinker, coal, coke, steel slag, gangue, cobble, limestone, silicon ore, quartz, concrete, chemical material etc
Description

Roller Crushers are generally applied for medium and fine crushing for various kinds of material with compression strength less than 320MPa, such as iron ore, cement clinker, coal, coke, steel slag, gangue, cobble, limestone, silicon ore, quartz, concrete, chemical material etc,.

Working principle

The two rollers of roller crusher rotate in opposite direction. The crushed material falls between the two rollers through the feeding port, and is crushed and crushed, and the finished material naturally falls. When there is a hard or unbreakable object, the roller of the roller crusher can be automatically retracted by the action of the hydraulic cylinder or the spring, so that the gap of the roller is increased, and the hard or unbreakable object is dropped, thereby protecting the machine from damage. The two rollers have a certain gap, and the gap can be changed to control the maximum discharge size of the product.

Product Advantage

1.Reasonable design, stable operation, simple operation and low operating cost

2.The use of medium hard tooth surface special deceleration fluctuations simplifies the transmission path, reduces the repair rate of spare parts, and improves the transmission accuracy and efficiency.

3.The spring force adjustment is convenient and reliable, and can provide different sizes of pressing force according to different materials.

4.Equipped with roller ring wear compensation mechanism, which makes the roller gap adjustment much easier and convenient, not only reduces the labor intensity and use cost of the operator, but also improves the utilization rate of the equipment and increases the service life of the roller ring.

5. Production of 4.75mm construction sand, sanding rate of up to 50%-60%

6. The grading of sand particles produced in accordance with the technical requirements of the national standard GB/T14684-2011 construction sand

7. Easy maintenance, consumable parts replacement cycle is longer than other equipment
