Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber powder processing crusher. Background Art

[0002] Rubber powder processing crusher, also known as rubber pulverizer, is a device specially used to process rubber waste. It uses the high-speed rotating blades in the crushing host to cut, tear and impact the rubber waste to break it into small pieces or powder. The crushed rubber waste is sieved through the screen to ensure that the discharge particle size meets the requirements. The presence of the screen can prevent overly large fragments from passing through the discharge port.

[0003] The existing patent announcement number CN213166352U discloses a rubber crushing device, which includes a first mounting frame and a first screen. During use, the waste rubber is transported to the inside of the chassis by the feeding mechanism, and the waste rubber falls onto the first crushing roller group for crushing. The crushed rubber particles fall onto the first screen on the first mounting frame for screening, and the particles with a particle size that meets the first screen size are discharged by the discharging part. At the same time, the vibration motor is operated in conjunction with the amplitude mechanism to make the first mounting frame vibrate up and down, which can improve the screening efficiency of the rubber particles while accelerating their movement. The particles with larger particle size roll quickly onto the second screen. The aperture of the second screen is larger, which mainly plays the role of slowing down the falling rate and regularizing the falling trajectory. Then, the particles pass through the second screen and enter the second crushing roller group for re-crushing, and then are discharged through the discharging part. Therefore, the purpose of rapid graded crushing of the waste rubber is achieved, and the particle size requirement after single crushing can be increased.

[0004] When the above device crushes the rubber, rubber particles will scatter in the chassis, and some substandard rubber particles will fall on the second screen, affecting the subsequent crushing and screening of the rubber. To solve the above problems, a rubber powder processing crusher is proposed. Utility Model Content
