我厂在一般情况下,真空过滤机过滤后的浮选精煤由皮带运输机运至斗式提升机,再由斗式提升机送至精煤装仓皮带运输机,然后装仓。但到防寒期,真空过滤机过滤后的浮选精煤必须送到干燥车间进行火力干燥后,才能装仓。因此,每年须改变两次流程。由于条件限制,防寒潮来临,必须把 I plant under normal circumstances, the vacuum filter flotation of flotation coal transported by the belt conveyor to the bucket elevator, and then sent to the bucket elevator bucket coal conveyor belt conveyor, and then bin. But to cold, vacuum filter flotation of coal after filtration must be sent to the drying plant for fire drying, to bin. Therefore, the process must be changed twice a year. Due to conditions, cold wave coming, we must put
