Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher with a dust removal structure. Background Art

[0002] A crusher, also known as a rock crusher, is a crushing machine used in the processing of metal ores and non-metallic ores. It can break the mined raw ore into small particles through extrusion and bending. Crusher is also often needed in water conservancy projects to carry out related work.

[0003] At present, in the prior art, a Chinese patent with announcement number CN212855978U discloses a raw material crusher for water conservancy projects with a dust removal function. The device uses a raw material crusher and a drum to crush the raw material multiple times while filtering out the crushed material to ensure the utilization rate of the raw material. A collection box is used to collect the crushed material. A humidifier is used to increase the humidity of the material collected in the collection box to prevent the dust generated when the material is poured out from polluting the air and endangering human health. An electrostatic precipitator is used to absorb the dust generated by the raw material crusher in the process of crushing the raw material to ensure the cleanliness of the crushing device and prevent excessive dust accumulation from clogging the internal components and affecting the use effect of the raw material crusher. However, in actual use, the device does not take into account that when too much material is fed, large pieces of gravel may cause clogging of the crushing drill bit, affecting subsequent use. In view of this, we propose a crusher with a dust removal structure. Utility Model Content
