1. Adjustable weirs 2. Sealed, submerged bearing 3. Optional automatic lubrication system 4. Rough tank and substructure
There are mainly four types of classifier: high weir single spiral classifier, high weir double spiral classifier, submerged single spiral classifier and submerged double spiral classifier. The equipment is mainly composed of driving device, spiral body, collection box, lifting unit, bottom support (engine bearing) and ore discharge valve.
Spiral Classifier Features and Benefits:
Our spiral classifiers have the advantages of simple structure, reliable working and easy operation. 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 device has two types, by electricity and hand.
Work principle of spiral classifier:
Spiral classifier mechanically classifies the ore materials through the mechanism of different sedimentation speed of solid particle in liquid due to different granularity and specific gravity. The fine ore floating in the water overflows out; and the coarse ore sediments on the tank bottom and then is pushed upwards by the spiral to be feed the grinding machine.
