Working principle
Working principle of LLWZ thickening and filtration centrifuge
The suspension will be fed into sedimentation rotor drum firstly for sedimentation and thickening before it’s transferred to the filtration rotor drum for filtration separation and rinsing.
The suspension will be fed in via the larger end of the sedimentation rotor drum. Solid content of which will settle down and lie on inner wall of the rotor drum, which will be conveyed to the smaller end of the drum under effect of screw; meanwhile, the liquid content of which will be discharged via overflow port at larger end of the drum. The filtering cake will be compressed and dehydrated as it’s conveyed from smaller end of the drum to the larger end.
The centrifugal force increases as the turning radius of the drum increases, reducing moisture content of the solid (which is high at beginning) as far as possible and achieving automatic continuous process of liquid/solid separation.
The unit is designed with washing pipe for rinsing and purification of filtering cake by end of filtration process, the thinner the filtering layer, the better effect of rinsing and the lower consumption of detergent.
For materials that are prone to secondary crystallization, steam pipes can be configured to clean the crystals out of the inner cavity at high temperature in preset frequency.
LLW horizontal decanter is mainly applicable for processing bulk material with lower solid content and liquid containing gel.
