Precautions in Classifier Operation

There are four kinds of classifier, such as high weir single spiral and double spiral classifier, sunken single spiral and double spiral classifier. This machine is widely applicable to shut mineral sands when the concentrator forms closed loop process with ball mills, or it is used to classifying mineral sand or fine mud, and make particle size grading in the metal beneficiation process in gravity concentrator plant, and washing mud and dehydration in washing job. The machine has a simple structure, reliable operation, easy to operate.Grading machine is taking advantage of the principle that the solid particle size is different, different specific gravity, and thus the settling velocity in liquid is different principle, fine mineral particles floating in the water will overflow, the coarse ore particles sink to the bottom. By screw pulling, it makers the upper discharge. It is able to filter the powder grinded by mill, and then the crude material is sent to the inlet by using a spiral piece, then the fine material that is filtered out is discharged from the overflow tube. The machine base is made of channel steel, and the body is made of welded steel plate. The spiral shaft head is made of pig iron sets, wear-resistant and durable, enhance device-electric and manual.
Selection of grading machine, you should pay attention to:
1. Material before classification should be in fully decentralized State;
2. The force of grading region is relative concentrated, the action site is the point or line, larger forces;
3. Processing the air, avoiding local whirlpool to improve grading accuracy;
4. The ultrafine particles should be discharged promptly after collection.
