Problems solved by technology

The main disadvantages of roller mills are low efficiency and high energy consumption
The grinding surface of the flat grinding disc grinder is flat. When the speed is constant, the linear speed increases from the center of the grinding disc to the edge of the grinding disc, and the wear is also increasing. The flat characteristic cannot be maintained for a long time, and it is difficult to repair the worn disc surface.

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0017] see figure 1 , figure 2 , the present invention is made up of movable grinding disc and fixed grinding disc. 1 is a fixed grinding disc, 2 is a triangular tooth of a fixed grinding disc, 3 is a moving grinding disc thread, and 4 is a moving grinding disc.

[0018] The feeding device generates a driving force on the rubber material, and continuously pushes the rubber material into the gap between the grinding discs. The rubber material first enters the area with a large gap from the large end; Crushing, reducing the size of the rubber material; then entering the area with small gaps, the area adopts narrower alveolar and shallow teeth, and further pulverizes the rubber material to achieve a satisfactory crushing effect.

[0019] The size of the cone angle of the movable grinding table has a great influence on the energy consumption ...

Abstract

The invention provides a grinding disc for a waste rubber smashing device and relates to a rubber mechanical component. The grinding disc for the waste rubber smashing device comprises a mobile grinding disc and a fixed grinding disc, wherein a gap between the two grinding discs is reduced gradually from a large end to a small end. The large end of the fixed grinding disc adopts wider tooth spaces and deep teeth, and the small end of the fixed grinding disc adopts narrower tooth spaces and shallow teeth. Conical convergence screw teeth are arranged on the smashing surface of the mobile grinding disc; a plurality of linear radial triangular teeth are formed in the smashing surface of the fixed grinding disc and clung to one another tightly. When waste rubber enters the gap between the mobile grinding disc and the fixed grinding disc through a propeller, the waste rubber is cut and ground through smashing teeth on the grinding discs, so that rubber powder is obtained. The cross section of each smashing tooth of the fixed grinding disc is triangular. The grinding disc is simple in structure, convenient to assemble and disassemble, high in smashing efficiency, low in unit energy consumption, smooth in feeding and discharging, uniform in smashing, small in grinding particle size and high in grinding quality.

Description

technical field [0001] The invention relates to a rubber mechanical component, in particular to a grinding disc of a waste rubber crushing device. Background technique [0002] Waste rubber shredder is one of the main equipments for rubber powder production. At present, the pulverizers used in the production of rubber powder are mainly roller pulverizers and various disc pulverizers. The main disadvantages of roller mills are low efficiency and high energy consumption. The grinding surface of the flat disc grinder is flat. When the speed is constant, from the center of the disc to the edge of the disc, the linear speed increases and the wear increases. The flat property cannot be maintained for a long time, and it is difficult to repair the disc after it is worn. Therefore, improving the design of the grinding disc structure is of great significance for improving the particle size and particle size distribution of rubber powder, improving crushing efficiency and reduci...
