Spiral classifier

product introduce:Screw classifier is one of the dressing equipment.It is a kind of equipment that makes use of different gravity of solid particles and different sedimentation rate in liquid to do mechanical classification.The machine is simple in structure, reliable in operation and convenient in operation.

Applications:it is widely used in the ore-dressing plant and ball mill to form the closed-circuit, separate and separate ore sand, or to grade ore sand and fine mud in the gravity concentrator.

Overview

Spiral classifier is one of the processing equipment It makes use of solid particle deposition rate is different in the different gravity and fluid mechanical classification of a device The processing of spiral classifier is used in the alluvial placer, especially suitable for high monomer dissociation degree useful minerals Shape flat placer spiral classifier is called classifier Classifier is mainly composed of transmission screw lifting mechanism of tank under the bearing (bearing shell) ore valve, etc Spiral classifier is widely applied in closed-circuit separate mineral sand mill and ball millOr used in gravity concentrator for ore grade sand and fine mud, ore size classification mud in the process of metal ore dressing, and deslimation in washing and dehydration operations

Features

The classifier is widely applicable to the closed-circuit separation of ore sand by the mill and ball mill, or used in the gravity concentrator to grade ore sand and fine mud, the grain-size classification of ore slurry in the metal dressing process, and the deslimation and dehydration in the washing operation.The classifier has the characteristics of simple structure, reliable operation and convenient operation.

Working Principle

The spiral classifier is based on the principle that the sedimentation rate in the liquid is different due to the difference of solid stone size and specific gravity.A grading device for mechanical grading by pushing the screw upward to the upper part of the mill to filter the powder in the mill.This machine base adopts channel steel, the machine body adopts steel plate welding.Screw shaft head, shaft head, using cast iron sleeve, wear - resistant durable
