Description

Technical Field

[0001] The utility model belongs to the technical field of sand making equipment, in particular to a side guard plate of a roller press. Background Art

[0002] The roller press, also known as an extrusion mill, roller press, or double-roller mill, is a new type of energy-saving cement grinding equipment developed internationally in the mid-1980s. It can replace the energy-intensive and inefficient ball mill pre-grinding system, reducing steel consumption and operating noise. It is suitable for new plant construction and for retrofitting existing plants, increasing system output by 30-50%. After extrusion, fine particles 0.08 mm in diameter account for 20-35%, while particles smaller than 2 mm account for 65-85%. The internal structure of the particles is filled with microcracks due to the extrusion process, significantly improving grindability. The roller surface is heat-hardened, creating a wear-resistant layer that is easy to maintain. Conventional side guards are used to protect the outer ring and circumference of the roller press. However, these side guards have a technical problem: the curved wear-resistant side cannot be machined, and manual grinding cannot guarantee a perfectly flat surface with the machined surface.
