The Roll Crusher Machine uses a single motor to drive the single shaft to rotate and push the material to move forward along the roll surface. The material is quickly dispersed and layered under the same thickness screening characteristics of the inclined roll surface (feeding section). The materials smaller than the gap between the roller shafts are subject to their own gravity and the rotating force of the roller shafts. They fall through the gap between the roller shafts (adjust and determine the gap before leaving the factory according to customer needs). The materials larger than the gap between the roller shafts remain on the roller shaft surface and continue to move forward, falling into the jaw crusher or other crushers, so as to achieve the purpose of debris separation and ore feeding.

Principle:
A roller screen consists of a series of cylindrical shafts or rollers that are arranged in a parallel configuration. These rollers are equipped with screening elements, which allow for the passage of particles of a certain size. The material to be sorted, in this case, soil and rocks, is fed onto the rollers and moves along their length due to the rotational motion of the shafts. As the material travels across the rollers, particles smaller than the screening elements pass through, while larger particles are retained and transported to the end of the roller screen.
Effectiveness:
The effectiveness of a roller screen for soil and rock sorting is determined by several factors:
Particle Size Separation: The screening elements on the rollers are carefully designed to allow particles of a specific size to pass through. By adjusting the spacing and configuration of the screening elements, the roller screen can effectively separate the material into different size fractions. This allows for the precise classification and sorting of soil and rocks based on their particle size.
Scalping and Removal of Oversized Material: Roller screens are particularly effective in scalping applications, where they remove the coarsest fractions or oversized rocks from the material stream. The screening elements are designed to retain larger particles, preventing them from passing through. This helps to improve downstream processes, reduce the load on crushers or conveyors, and ensure the desired size distribution of the sorted material.
Handling High Volumes of Material: Roller screens are capable of handling high volumes of material due to their robust design and efficient material transport mechanism. The rotational motion of the shafts and the inclination of the rollers facilitate the movement of the material along the length of the roller screen, allowing for continuous and efficient sorting operations.
Durability and Low Maintenance: Roller screens are typically constructed with sturdy materials and components, ensuring durability and longevity even in demanding environments. They are designed to withstand the abrasiveness and impact of soil and rocks, minimizing the need for frequent maintenance or replacement.
