High Weir Spiral Classifier

High Weir Spiral Classifier

Introduction

Classifying equipment takes use of the different sedimentation speed of the solid particle in slurry.

Capacity

10~1785 t/d

Product improvement

An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation.

Product Application

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 classification of ore with particle size 0.83-0.15mm

Working Principle

The grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification 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.

Separation Drawing

High weir spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also applied in de-mudding and dewatering.
