Roller layered structure of pair-roller-type pelletizer

Abstract

The invention relates to a roller layered structure of pair-roller-type pelletizer applied on pair-roller-type pelletizer. The roller layered structure comprises rollers arranged on the frame below the feed hopper, the frame is divided into four layers and provided with rollers, each layer comprises two rollers, the axes of two rollers are on one plane, the rotating directions of each pair of rollers are opposite, a material inlet end is arranged above the rollers of the first layer, the material is extruded to the above of the rollers of the second layer, on the analogy of this, a material outlet end is arranged below the rollers of the fourth layer and the material is extruded by the rollers of the fourth layer to be pelletized, side plates for converging the material out of the previous layer to the next layer are mounted at two sides of each pair of rollers, the four layers of rollers act continuously, thus facilitating graphite powder to be pelletized and satisfying requirements on pellet size and hardness; the length and rotating speed of the rollers change level by level, thus avoiding graphite powder from being incapable to be pelletized owing to undue dispersion, and facilitating adjustment to discharge speed and pellet hardness.

Description

technical field [0001] The invention relates to a roller layered structure of a double-roll granulator used on the double-roll granulator. technical background [0002] The current granulator is a pair of rollers, and the speed cannot be adjusted. This kind of double-roller granulator with only one layer of roller structure has the following defects: because it is a one-time granulation, the hardness of the granulation is not enough, the granulation is not shaped, it cannot meet the needs of actual production, and it is not suitable for process automation. Require. Especially in the process of granulating graphite powder in the field of diamond manufacturing, the requirements for the hardness of this granulation are higher. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the existing granulator and provide a counter-roller that adopts multi-layer rollers and changes the length and speed layer by layer, so that the par...
