Did You Dig the Value of Screw Classifier?

Spiral classifier, also called screw classifier or screw separation machine, is one kind of mineral separation equipments. Due to different specific gravity of different powder sizes, the speed of powders’ sedimentary in liquid are different. Spiral separator against this theory to reach mechanical classification. Filter the material powders from grinding mills first, the coarse powders will be screwed into the ball mill inlet opening, fine powders will be discharged through the overflow pipe. Spiral classifier machine is short called by classifier. It mainly have high weir single spiral and double spiral, immersed weir single spiral and double spiral four types.

The spiral classifier is shortened as classifier which is a commonly used classifying machine during the ore beneficiation process. It can be combined with the ball mill to form a closed cycling system in order to split the ore flow, or used in the gravity dressing process for splitting the ore sand and fine mud. In addition, it can also be used for demudding and dewatering in the ore washing process.

According to the working 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 screw separator 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 this ore beneficiation machine adopts channel steel and body adopts armor plate and the spiral axle adopts wrought iron, so it is durable. The lifting equipments have two types, by electricity and hand.

Screw separator is used to the mechanical grading by means of the spiral that will push the materials to the upper to be discharged. Spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity...
