Description

Technical Field

[0001] The utility model relates to the technical field of limestone crushing, in particular to a limestone multi-stage crushing mechanism. Background Art

[0002] The cement industry often uses limestone as raw material, but since limestone is mostly in large blocks when it is transported to the cement plant, it needs to be crushed;

[0003] After searching, the applicant found that a Chinese patent disclosed "a multi-stage crushing mechanism for limestone", and its publication (announcement) number is "CN 219631433U". The patent mainly provides a crushing machine body, a storage car and a first crushing roller. Limestone raw materials are poured into the crushing machine body, and a dust-proof telescopic cover is fixed on the lower end surface. A fixed block is welded on the lower end of the dust-proof telescopic cover, and a dust-proof brush is installed on the outer side of the fixed block. The crushing machine body is connected to a dust suction pipe through a branch pipe, and a dust suction machine is connected to the lower end of the dust suction pipe. A fan is installed in the dust suction machine cavity. The utility model solves the problem in the prior art that more dust is generated when limestone is squeezed and crushed twice, and limestone dust is easily inhaled into the lungs of workers, damaging the health of workers and destroying the environment, and it is difficult to prevent dust from overflowing when limestone is crushed. However, the device can only obtain limestone of one size, and is not very practical. At the same time, when the dust is collected, the device needs to be stopped to replace the dust collection bag, which affects the work efficiency. For this reason, we propose a multi-stage crushing mechanism for limestone. Utility Model Content
