本刊讯原料破碎特别是煤矸石和页岩的破碎一直困扰着烧结砖瓦行业。业内以锤破为主,虽然有些厂家的细锤破粉料较多,但20%~50%的回料(筛上颗粒料)使破碎效率大大降低,反复破碎增加了电耗,40t/h的设计破碎能力只能破20t~30t粉料。因此,为满足生产线要求,只能将破碎能力增大到70t/h~80t/h,电动机功率由132kW提高到180kW或更大,破碎机的体积也越来越大,而且由于粉料不足,不少厂家一再缩小筛分网眼使破碎机效率进一步降低。笼破虽然破碎效果较好,但设备磨损严重,维修工作量大。滚筒破解决了煤
The news of broken raw materials, especially coal gangue and shale crushing has been plagued sintered brick industry. Hammer broken in the industry-based, although some manufacturers hammer broken powder more, but 20% to 50% of the back material (sieve particles) greatly reduce the crushing efficiency, repeated crushing increased power consumption, 40t / h The design of broken capacity can only break 20t ~ 30t powder. Therefore, to meet the production line requirements, the crushing capacity can only be increased to 70t / h ~ 80t / h, motor power increased from 132kW to 180kW or more, crusher volume is also growing, and because of insufficient powder, Many manufacturers have repeatedly narrow the mesh to make crusher efficiency further reduced. Broken cage although broken better, but serious equipment wear and tear, heavy maintenance workload. Drum broken solved the coal
