我厂铸工车间焦炭末的用量较大,过去用电碾粉碎,焦炭末经常供应不足,而且粉尘也很重要。为了满足生产需要,我们改用了锤式粉碎机。但由于粉碎机锤头的材料硬度和耐磨性都达不到要求,粉碎锤头部磨损很快,每月都要换一次新锤,这就给设备维修造成了很大 I plant a large amount of coke at the end of the casting plant, in the past by electric grinding crushing, coke often lack of supply, but also the dust is also very important. In order to meet production needs, we switched to hammer mill.
