AI Technical Summary
During the crushing process, the roller press exhibits an edge effect. The middle part has a good extrusion effect and produces a large amount of fine powder, while the edge extrusion effect is poor, resulting in less fine powder or even material leakage. Furthermore, severe wear of the side baffles leads to a larger working gap and serious material leakage at the edges.
The rollers of roller one and roller two are designed with convex and concave roller surfaces, and annular rolling grooves are set on both ends of the rollers to install balls. Rolling plates are set on the side baffles to cooperate with the rolling. The balls are in contact with the rolling plates to reduce wear.
It achieves uniform material distribution, avoids edge effects, reduces wear, ensures stable output, increases fine powder production, and prevents material leakage.

TECHNICAL FIELD
[0001] The utility model relates to cement production device technical field, concretely relates to a roll structure of roll press for raw material preparation. BACKGROUND
[0002] The roll press is designed according to the material bed grinding principle, and material is fed from above two rollers, is continuously taken into the roller by the extrusion roller, and becomes dense material cake after being subjected to the action of 100-150MPa high pressure and is discharged from the machine.
[0003] When the roll press is crushed, material is extruded to both sides while being rolled, edge effect is generated, the middle part extrusion effect is good, fine powder production is more, and the edge extrusion effect is poor, fine powder is less or even material leakage, that is, bypass failure.When the working gap value becomes larger when the two end side baffles are seriously worn, edge material leakage is inevitable, the fine powder content of the material after extrusion is significantly reduced, and part of the coarse particle material will also enter the subsequent dynamic or static classification equipment, causing great wear to the internal classification machine. Therefore, the roll structure of the roll press for raw material preparation is provided. SUMMARY
[0004] In order to overcome the problems in the background art, the roll structure of the roll press for raw material preparation is provided, which solves the problems of edge effect of the roll press, good extrusion effect of the middle part, more fine powder production, poor edge extrusion effect, less fine powder, and even material leakage.
[0005] A roll structure of a roll press for raw material preparation, comprising rollers one and two installed adjacent to roller shaft one and roller shaft two, side baffles installed at both ends of the roller shaft one and the roller shaft two, a gap between adjacent roller surfaces of the rollers one and two, the roller surfaces of the rollers one and two being concave-convex roller surfaces concave upward and downward, and the concave surfaces and the convex surfaces of the concave-convex roller surfaces of the rollers one and two corresponding to each other.
[0006] Further, annular rolling grooves are arranged on both end surfaces of the rollers one and two, balls are installed in the rolling grooves, rolling plates cooperating with the rolling grooves are arranged on the side baffles, and the balls are in contact with the rolling plates.
[0007] Further, the distance between both end surfaces of the roller one on the roller shaft one and the side baffles is 2-3mm.
[0008] Further, the rolling plate is a wear-resistant plate.
