Description 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.
Advantages of Spiral Classifier
- Simple structure and steady performance
- Reliable working condition and less fault
- Simple structure and reliable operation
- Advanced technology and low failure rate
