Technical Field

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

[0002] White carbon black is a general term for white powdered X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica and ultrafine silica gel, and also includes powdered synthetic aluminum silicate and calcium silicate.

[0003] In the preparation process of silica, it is often necessary to use a crushing device to crush the material to reduce the volume of the material and facilitate subsequent processing of the material.

[0004] Chinese utility model patent CN218190042U discloses a material crushing device for commercial concrete processing, comprising: a box body; a feed port, which is connected and arranged on the right side of the box body; a dust removal mechanism, which is arranged on the box body; the dust removal mechanism comprises: a chassis, which is fixedly installed on the top of the box body; an L-shaped pipe, which is connected and arranged on the box body, and one end of which passes through the top of the box body and extends to the inside of the box body; a dust removal head, which is fixedly connected to one end of the L-shaped pipe located inside the box body; a protective groove, which is fixedly connected to the top of the inner wall of the box body, and the opening faces upward; the utility model starts the exhaust fan inside the box body, and the dust generated during crushing is sucked into the inside of the box body through the L dust removal head and the L-shaped pipe, so as to achieve the dust removal effect, avoid dust from being emitted into the air to pollute the environment, and protect human health.

[0005] In order to crush the materials, the material crushing device is equipped with a motor and a crushing knife.
