Continuous and automatic feeding and discharging , small floor area , low operation intensity . Channelization of all pipes , good leakproofness and realize automatic working . Mainly used in the process of slag removal for crude oil , can further reduce soild content and mechanical impurities . Treatment capacity : 1 - 4 0 m / h .

2.Working principle 

Drum and spiral rotate at a certain different speed , the mixed liquid enters into spiral feed space continuously through feeding pipe and speed up into the drum . Under the effect of centrifugal force , solid - phase sedimentates on inner wall of drum and forms sediment layer . Sedimentated solid is pushed to the cone end of drum continuously by spiral pusher and dried at drying area and then discharged . Liquid phase forms inlayer liquid ring and overflows from drum through overflow port of big end , finally , the liquid phase is discharged from outlet port .
