Double Roller Crusher
The double roller crusher is Suitable for cement, chemical industry, electric power, metallurgy, building materials, refractory materials and other industrial sectors to crush medium or high hardness materials,。
Capacity: 1.5-70 t/h
Applicable materials: limestone, slag, coke, coal and other materials.
Description
Double-roller crusher is also called double-roller sand making machine and double-roller crusher. The whole machine has a compact and reasonable structure and can be used for both crushing and sand making. One machine for multiple purposes. It is mainly used for fine crushing operations with ore particle size less than 80mm. It has the advantages of small size, large crushing ratio, low noise, simple structure and convenient maintenance. The particle size of the crushed material is uniform, the over-crushing rate is low, and the particle size of the finished product is 0.5-40mm.
Advantages
- The discharge port gasket adjustment device is set, and the discharge port particle size is adjustable.
- The crushing roller is made of super wear-resistant alloy and has a long service life.
- When crushing hard materials or unbreakable materials, the hydraulic spring system can give way to allow foreign objects to pass through to prevent damage to the machine.
- The feeding is uniform and the crushing efficiency is high.
Principle
The crushing part of the double-roller crusher has a fixed roller and a moving roller. The broken stones fall into the V-shaped crushing cavity between the two crushing rollers. The two rollers rotate in opposite directions to squeeze and shear the stones.
