Description

Technical Field

[0001] This utility model belongs to the field of crushing equipment technology, specifically relating to a crushing and feeding device for the production of iron oxide pigments. Background Technology

[0002] In the production of iron oxide pigments, raw materials typically undergo preliminary crushing, medium crushing, and ultrafine crushing. Preliminary crushing usually involves using a jaw crusher to coarsely break the raw materials into 1-3 cm pieces. These 1-3 cm pieces are then fed into a pulverizer to further crush them into coarse powder of 0.1-0.3 mm. Finally, the coarse powder is sent to ultrafine crushing equipment, such as an air jet mill, to complete the ultrafine crushing process. During the medium crushing stage, the pulverizer breaks the raw materials into coarse powder, which is easily dispersed, causing environmental pollution and wasting raw materials.
