Description

Technical Field

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

[0002] Material is a professional term in my country's production field. Manufacturing enterprises are accustomed to referring to all materials (regardless of whether they come from means of production or means of living) circulating in the production field, fuels, parts, semi-finished products, outsourced parts, and scraps, scraps and various wastes inevitably generated in the production process other than the final product as "materials". Materials often need to be crushed and screened, and external force is applied to the solid materials to split them into smaller particles. Materials of appropriate size can be screened out for use.

[0003] Existing material crushing and screening are often carried out using different mechanical equipment. First, crushing is performed by a crushing machine, and then screening is performed by a screening machine. The use of multiple mechanical equipment is inefficient. At the same time, the materials that fail to pass the screening need to be manually collected and transported through the feed port again, which reduces the work efficiency. For this reason, we propose a material crushing and screening machine. Utility Model Content
