Description

Technical Field

[0001] The utility model relates to the technical field of powder separation, in particular to a powder separation device of a pulverizer. Background Art

[0002] A crusher is an electric machine that mainly crushes large-sized solid raw materials into required sizes. It is widely used in mining, building materials, agriculture, medical care and other fields.

[0003] The existing crusher is mainly composed of a body, a crushing mechanism and a driving part. When crushing, the material is first fed into the crushing chamber through a feed hopper. The crushing mechanism is rotated by the driving part, and the material is impacted, sheared and rubbed by the high-speed rotating blades or hammers, thereby changing the material from larger blocks or solids into smaller particles.

[0004] During the pulverizing process, the material is hit, cut and rubbed by the high-speed rotating blades or hammers. Although the material can be broken into smaller particles, a certain amount of powder will be produced at the same time. The existing pulverizers have the disadvantage of being difficult to separate the powder, so that the powder is often mixed with the pulverized granular material and is difficult to separate completely. The presence of powder will have an adverse effect on product quality and use effect. Therefore, a powder separation device for a pulverizer is proposed to address the above problems.
