The type of roller of the roller crusher and its applicable materials​

​
As the key equipment in the field of material crushing, the roller crusher, the choice of roller type plays a decisive role in the crushing effect and the scope of applicable materials.Different types of rollers have unique structure and performance characteristics, which are suitable for diverse material characteristics.An in-depth understanding of the roller types of roller crushers and their applicable materials will help users accurately select the types and improve production efficiency and product quality.​

Glossy roller​

The surface of the glossy roller is smooth and flat, and the material is mainly broken by extrusion during the crushing process.This kind of roller is suitable for crushing materials with relatively uniform texture and moderate hardness, such as limestone, shale, etc.Limestone is commonly used in cement production. Its texture is relatively uniform, and smooth rollers can stably apply pressure to it to break it into the desired particle size.Shale is widely used in the brick-making industry. Smooth rollers can break the shale along the weak internal structure under extrusion, producing particles with particle sizes that meet the requirements of brick-making.Since there is no special structure on the surface of the glossy roller, it is not easy to cause excessive grinding of the material during the crushing process, and the particle shape of the material can be better maintained to meet the production scenarios with high requirements for product particle size and particle type.​

Tooth surface roller​

The surface of the toothed roller has a special toothed structure. Compared with the smooth roller, the crushing method not only squeezes, but also increases the tearing and shearing effects.This kind of roller is suitable for crushing materials with greater hardness and toughness, such as coal gangue, iron ore, etc.Coal gangue has high hardness and certain toughness. It is difficult for ordinary smooth rollers to break effectively. The toothed structure of the toothed roller can be embedded inside the coal gangue and broken by tearing and shearing, reducing the difficulty of crushing and improving the crushing efficiency.Iron ore needs to be broken before smelting. The toothed roller can rely on the unique toothed design to effectively crush the bulk structure of iron ore, so that the particle size of iron ore meets the requirements of the subsequent smelting process.The tooth shape design of the tooth surface roller is rich and diverse, and can be customized according to the characteristics of different materials to achieve the best crushing effect.​

Grooved roller​

The surface of the grooved roller is designed with grooves of a specific shape, which can increase the contact area with the material when crushing, and improve the clamping force and conveying capacity of the material.Grooved rollers are suitable for handling materials with high viscosity and easy to agglomeration, such as clay, wet coal, etc.The clay is highly viscous in its natural state and is easy to stick to the surface of the equipment. The grooves of the grooved rollers can effectively prevent the clay from sticking. At the same time, the groove structure is used to squeeze and rub the clay during the crushing process to break it into fine particles.Because wet coal contains moisture, it is prone to agglomeration. Grooved rollers can disperse wet coal through grooves to achieve efficient crushing.The groove shape and size of the grooved roller can be optimized according to the viscosity and particle characteristics of the material to ensure stable operation when handling viscous materials and reduce the risk of equipment clogging.​

There are many types of rollers for roller crushers, and each type plays a unique advantage in the crushing of specific materials.When users choose the roller crusher and the corresponding roller type, they need to fully consider the hardness, toughness, viscosity and other characteristics of the material, and make scientific and reasonable decisions based on the production process requirements, so as to achieve the efficient operation of the roller crusher and maximize production efficiency.​
