Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller grinding machine equipment, in particular to a circulating grinding roller grinding machine. Background Art
[0002] Roller mill is a commonly used industrial equipment used for crushing and grinding materials. It uses one or more sets of rollers to compress, shear and grind the materials to achieve the required fineness and particle distribution. Roller mills are usually composed of one or more pairs of parallel rollers. The gap between the rollers can be adjusted to control the grinding effect of the materials. When the materials pass through the gap between the rollers, they are subjected to the pressure and shear force of the rollers, so that the materials are dispersed, crushed and ground. Roller mills usually use a closed-loop system during the grinding process, which can realize the circulation grinding of materials, reduce energy consumption and improve production efficiency. Roller mills have large processing capacity and high grinding efficiency, which can meet the needs of large-scale industrial production.
[0003] However, the existing horizontally arranged roller grinders cannot perform secondary grinding after the particles fall off the grinder due to unidirectional grinding during the grinding process. Large particles need to be added back into the grinder after subsequent screening and ground again, which reduces the processing efficiency to a certain extent.
[0004] In view of this, we propose a roller mill for circulating grinding. Utility Model Content
