Description of Spiral Classifier

This classifier can filter materials and send coarse materials to the feeding mouth and discharge fine materials from the pipe. The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for durability. The machine's lifting equipment can be used manually or electronically.

 

Working Principle of Spiral Classifier

Classifier is a classification tank mounted tilt, pulp from the top of the tank to enter, heavy particles sink to the bottom, by a screw conveyor to the upper tank discharge, becoming sand back. If and when a closed-circuit grinding mechanism, the sand back into the grinding machine regrinding. Fine, light particles with the slurry flow through the lower tank overflow discharge. To achieve the purpose of classification.

 

Applicatiion of sprial classifier

Classifier is widely used in ball mill in the concentrator and the match into a closed cycle cheng cheng shunt mineral sand, or in the gravity concentrator to grading ore and fine clay, and metal beneficiation process for the pulp particle size classification, and washing of desliming, dehydration and other operations.The machine has simple structure, reliable work, convenient operation, etc.Classifier is by means of solid grain size is different, the proportion of different, therefore in the liquid velocity for different principle of fine particles floating in the water in the overflow, coarse particles sink on the bottom of the channel.Conducted by spiral to the upper discharge and mechanical classification of a grading equipment, can grinding mill in the powder level in the filter, and then the coarse material using spiral vane rotary screwing in mill inlet, to filter out the fine material discharge from the overflow pipe.The machine base with channel steel, the body USES the steel plate welded together.Screw shaft into the head, shaft head, pig iron, wear-resisting durable, electrical and manual lifting device

 

Features of Sprial classifier
