The spiral classifier is based on the principle that the solid particles are of different sizes and specific gravity, and thus have different sedimentation speeds in the liquid, with the fine particles floating in the water as an overflow and the coarse particles sinking at the bottom of the trough. Pushed by the spiral to the upper discharge, to carry out mechanical classification of a classification equipment, can be ground in the mill material powder grade in the filter, and then the coarse material using the spiral piece of spinning into the mill inlet, the filtered fine material from the overflow pipe discharge. The base of the machine is made of channel steel and the body is made of welded steel plate. The inlet head and shaft head of the spiral shaft are made of pig iron bushings, which are wear-resistant and durable, and the lifting device is divided into two kinds: electric and manual.
High wear resistance, low maintenance rate
Reliable operation, convenient and flexible
