Introduction and Application of Spiral Classifier
There are four types of classifiers, high weir type single and double spiral classifier, immersed single and double spiral classifier.
Spiral classifier (Screw classifier) is 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. Advantages are simple structure, reliable working condition and convenient operation. 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.
This Spiral 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.This product features simple structure, reliable working conditions and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to flow in the water, while coarse ore sinks to the bottom.
Spiral Classifier is suitable for separating of fine particles and liquid from coarse particles Separation of light particles from heavy particles Separation of the particles into a number of products graded according to size Separation of liquid from solid particles
Features and Usage of Spiral Classifier
Spiral classifiers are suitable for:
a.Separation of fine particles and liquid from coarse particles
