[0002] The cement raw meal mill is a core piece of equipment in cement production. It is responsible for grinding raw materials such as limestone, clay, and iron powder to a fineness that meets the required threshold, forming uniform raw meal powder for subsequent calcination in a rotary kiln to produce clinker. The cement raw meal mill feed inlet is a key component connecting the raw material conveying system and the mill. Taking the structure of the cement raw meal mill feed inlet as an example.

This makes it inconvenient to modularly disassemble, assemble, and replace the wear-resistant buffer plate. Furthermore, the single-slope feed ramp and the drop area of ​​the cement raw meal are subjected to a large impact force, resulting in poor energy-consuming buffering effect on the cement raw meal. Therefore, to address the above problems, an impact-resistant and wear-resistant buffer device for the feed inlet of a cement raw meal mill is proposed. Utility Model Content
