Classifying equipment takes use of the different sedimentation speed of the solid particle in slurry. Production capacity101785 t/d.Product ImprovementAn automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation.The grinded pulp is fed into tank from the inlet in the middle of settlement region and the slurry classifiion sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry so that the fine particles rise and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft and is underneath overflow end.
High weir spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also applied in de-mudding and dewatering.
The overflow spiral blade is higher than overflow level and the overflow spiral center is lower than overflow surface. The high wire spiral classifier is applied in the classifiion of ore with particle size 0.83-0.15mm.
