Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing and production, and particularly relates to a drum separator with high working stability. Background Technique

[0002] A drum separator is a mechanical device used for solid particle separation, mainly applied to the classification of particulate substances such as coal, minerals, and grains. The structure of the drum separator mainly consists of a drum, a spiral pusher, a screen, a motor, etc. During the plastic processing and production process, a drum separator is often needed to screen plastic particles.

[0003] However, when the existing drum separator is in use, there are still the following deficiencies: When plastic particles pass through the screen cylinder of the drum separator, the screening time cannot be well controlled. Due to the too fast sliding speed of the plastic particles, the plastic particles cannot be sufficiently screened, resulting in incomplete screening of the plastic particles. In response to this, we propose a drum separator with high working stability to solve the above-mentioned problems. Content of the Utility Model
