New Design Single Double Gold Spiral Classifier Spiral Sand Washing Machine

Introduction

According to the principle that different grains are with different specific gravity and sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks in the bottom. The classifier that has machine grading by discharging from the top can filtrate the materials and send coarse materials to the feeding mouth and discharge the fine material from the pipe. The seat of the machine adopts channel steel and body adopts armor plate and the spiral axle adopts cast iron, so it's durable. The lifting equipments have two types, by electricity and hand. There are four types of classifiers, high weir type single and double spiral classifier, immersed single and double spiral classifier.
Application for spiral classifier mining

Application

Spiral classifiers are widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and desliming and dehydrating in the washing.

High weir spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also

applied in de-mudding and dewatering.

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.
