Description

Technical Field

[0001] The utility model relates to the technical field of lime production, in particular to a crushing device used for lime production. Background Art

[0002] Lime is widely used. It can be used as the foundation of buildings, the cushioning layer of roads or ground, and as plaster for application, which is beneficial for dispersing lumps and accumulations in the body. It can be used as medicine to dry dampness, kill insects, stop bleeding and relieve pain. Lime production requires quarrying, kiln loading, kiln firing and cooling. After quarrying, crushing equipment is needed to crush the raw materials.

[0003] The crushing structure of the existing lime production crushing equipment is relatively simple. Most of them crush the stones by uniaxial rotation of the crushing roller, which has a poor crushing effect on the stones. In addition, the existing lime production crushing equipment has a large number of stones put into the crushing equipment at a single time, and there is a lack of downward pressure on the stones at the top. It only relies on the stone's own gravity, resulting in low crushing efficiency. For this reason, we propose a crushing equipment for lime production. Utility Model Content
