This is a 900*900 fully hydraulic double-tooth roller crusher. It is loaded and sent to South Africa. It is used on-site to crush asphalt milling materials. This machine is widely used to crush asphalt milling materials, gypsum, coal, limestone, etc. Materials with lower hardness have the characteristics of high lump formation rate, low powder extraction rate, and no damage to the internal structure of the material. I hope the boss’s business is prosperous.

The teeth on the roller crusher play a crucial role in crushing and compacting materials. These teeth are typically distributed on the surface of the roller and serve the following key functions:

1. Crushing Materials: The teeth on the roller come into contact with the materials during operation, using their shape and force to crush them. Roller crushers usually work in pairs, with materials being crushed between two sets of rollers.
2. Squeezing and Compacting: The teeth of the roller can not only crush materials but also squeeze and compact them. When materials are caught between two rollers, the pressure exerted by the teeth squeezes and compacts the materials, thereby altering their shape and size.
3. Dispersion and Mixing: In certain applications, roller crushers are also used for dispersing and mixing materials. By adjusting the speed and clearance of the rollers, it’s possible to achieve dispersion and mixing of materials to meet specific process requirements.
4. Controlling Particle Size: The design and layout of the roller teeth can influence the particle size and uniformity of crushed materials. By adjusting the tooth shape, spacing, and number, it’s possible to control the degree of crushing and obtain the desired particle size distribution.

In summary, the teeth on the roller crusher, through actions such as crushing, squeezing, and compacting, facilitate the processing and handling of materials, making them a crucial component for effectively fulfilling the crushing tasks of the equipment.
