Intermediate Broken Double Roller Crusher 300-500 TPH Soft Rock Crushing

Product Description

The Double Roller Crusher with a relatively large crushing ratio, it can can control the output particle size to be less than 40-70mm, and the input material to be less than 160mm.

Such a machine has great advantages. Because of the high production capacity, the Double Roller Crusher replaces the situation of multiple machines working at the same time. The Double Roller Crusher requires only one plant foundation, which reduces the cost of multiple plant foundations. The Double Roller Crusher has a low operating load through the v-belt drive, so it has a very low failure rate. Compared to the production line of multiple crushing plants, it reduces the possibility of failure rate and loss in the crushing work of multiple plants.

Therefore, the Double Roller Crusher can achieve the crushing results of multiple plants when used as intermediate crushing. At the same time, it can create big advantages with the cost of a single machine, foundation cost and low energy consumption.

Crushing Principle

The Double Roller Crusher operates based on the principle of compression and shearing. It consists of two parallel cylindrical rollers that rotate in opposite directions. The material to be crushed is fed into the space between the rollers, and as they rotate, the material is pulled in and compressed between the rollers.

The crushing process in the Double Roller Crusher involves two main actions:

Compression: As the material enters the crushing chamber, it is subjected to the compressive force exerted by the rotating rollers. The material is squeezed between the rollers, causing it to deform and break into smaller particles. This compression action is crucial for reducing the size of the material.

Shearing: In addition to compression, the Double Roller Crusher also applies a shearing force to the material. The interlocking teeth or spikes on the rollers create a shearing effect as they move past each other. This shearing action further breaks down the material, resulting in finer particles.

The combination of compression and shearing forces in the Double Roller Crusher efficiently breaks down the material into smaller, more manageable sizes. The adjustable gap between the rollers allows for precise control over the final product size. By adjusting the gap, operators can achieve the desired particle size distribution for specific applications.

The Double Roller Crusher is particularly effective in crushing materials with medium to high hardness. The interlocking teeth or spikes on the rollers provide a strong grip on the material, preventing it from slipping during the crushing process. This ensures a thorough and efficient crushing action, resulting in a uniform product with minimal fines.

Overall, the working principle of the Double Roller Crusher revolves around compression and shearing forces. This crusher's design and operation make it a reliable and efficient tool for crushing various materials in mining, construction, and other industries.
