The toothed roller crusher is a new type of equipment developed on the basis of double roller crushers. Both are a type of roller crusher and both use rollers to squeeze the materials to crush the materials. They are commonly used crushing equipment in the mining industry. But what is the difference between them? Today we will explain to you the differences between double roller crusher and toothed roller crusher.

Different application and characteristics

The double roller crusher is widely used in metallurgy, building materials, refractory materials and other industrial sectors to crush medium and high hardness materials. It has the characteristics of low noise, less dust, reliable performance and convenient maintenance. The toothed roller crusher is suitable for coal, metallurgy, mining, chemical, building materials and other industries, and is more suitable for the crushing of raw coal in large coal mines or coal preparation plants. It has the advantages of small size, large crushing ratio, low noise, simple structure, convenient maintenance, high productivity, uniform finished product size, low over-crushing rate, convenient maintenance, sensitive overload protection, safety and reliability.

Different working principle

The double roller crusher adopts the working principle of squeezing of the rollers with low speed and high pressure. The roller crusher contains two smooth rollers. During production, the material falls vertically from the upper part of the crusher into the crushing cavity, and the strong pressure generated between the two rollers squeezes each other to broken the material.

The toothed roller crusher can be divided into two types: double-toothed roller crusher and four-toothed roller crusher. When the crusher is in production, the material flow enters the two-roller V-shaped crushing cavity and will collide with the high-speed rotating toothed rollers. And the surface of the roller is covered with tooth-shaped crushing bodies, and the material is split by rotating and squeezing when the machine is working, so as to achieve the purpose of crushing.

Different structure

The double roller crusher is usually composed of body, base, fixed roller, movable roller, transmission device, and safety device. The gear transmission device is mainly composed of fixed roller, movable roller, transmission shaft, body, chassis, cover, and Long gear cover and other parts. The toothed roller crusher is composed of active toothed roller, reducer, hydraulic coupling, motor, electric oil supply pump, passive toothed roller, arcuate toothed plate, side toothed plate, side toothed plate seat, lower body, and speed measuring device.

Different sizes of crushed materials

The double roller crusher uses the method of squeezing friction to crush the material with finer particle size. While the toothed roller crusher uses toothed rollers to break the material, and the material is granular with relatively coarse particle size.
