The wear mechanism of mill beaters for coal grinding made-up

网页2022年12月1日The grindability is most often determined by the Hardgrove and Ball Mill method [11]. Beater mills consist of beaters mounted on the perimeter of the disc or mounted on the shaft, which grinds the coal as a result of the impact, as well as the friction of the coal against the structure of the mill.
