Introduction of Spiral Classifier

The spiral classifier is a mining machinery which is mainly used for separating and classifying of minerals after grinding. This spiral classifier is widely used to separate mineral sand with closed circuit ball mill. This product can be used for grading sand and fine mud in the gravity separation, classifying mineral size in metal ore beneficiation, mud removal and dehydration in ore beneficiation.

Working principle of Spiral Classifier

Spiral classifier comes from the theory that granules with different dimensions and specific weights will sink in water at different speeds, fine mine granules float around in water or overflow, rough mine granules sink down to the bottom, so in this way the mechanical separation can be achieved. It can be separated and filtered materials grinded in a ball mill, the rough materials will be discharged through the spiral to feed opening of the ball mill, and the fine materials will be discharged from overflow pipe, it is widely applied for separating mine sands for closed circuit circulation formed by concentrating mill and ball mill, as well as for desliming and dehydrating during mine washing works.

Advantage of Sprial Classifier

• Simple structure and steady performance;
• Reliable working condition and less fault;
• Simple structure and reliable operation;
• Advanced technology and low failure rate;
