Mining Machinery Immersed Type Single Sand Spiral Classifier

High-tech Spiral Classifier with Ore Beneficiation and Dressing

       Spiral classifier is one type of Classifiers in Mineral Processing ,gold mining equipment,Zircon Sand Separation Machine, based on user requirements, it can be divided into single and double spiral classifier. Depend on specific gravity of solid particles, so different sedimentation velocity in a liquid principle, spiral classifier is a mechanical grading equipment. Feed mill can grind the powder level in the filter, and then use the coarse material spiral piece rotary vane screwed mill feeder to filter out fine material discharged from the overflow tube. Spiral classifier /spiral washer referred grader.

Spiral Classifier for Mining Working Principle:

    Mining Spiral Classifier is by means of solid particles of different sizes, the proportion of different, thus settling velocity in liquids of different principles, fine mineral particles floating in the water to overflow out of coarse mineral particles sink to the bottom. Discharged from the screw into the upper part, to a hierarchical classification of mechanical equipment, can mill to grind the material powder level in the filter, and then use the coarse material helical screw rotary vane into the mill feed, the filter out the fine material is discharged from the overflow pipe. The machine base is made of channel steel body with steel plates welded together. Into the head of the screw shaft, shaft, using pig iron, wear-resistant and durable, lifting devices of electric and manual.

The test run of the spiral classifier should be carried out according to the following requirements:

1. No-load running time is 4 hours;

2. The lifting device is tested twice during the whole process to check whether the limit is appropriate and adjust it;

3. Before the screw classifier is put into trial operation, the water tank shall be filled with water for a leak test without leakage.

4. When the classifier is running under load, the screw should be started before feeding; when the machine is stopped, the feeding should be stopped, and the screw operation should be stopped after the mineral in the tank is transported;

5. When the classifier is running under load, if an emergency stop is required due to a failure, the lifting device should be started first, and the spiral blades should be raised above the mineral sedimentation layer to stop the operation. When starting again, start the screw first, wait for the rotation to be stable, and then slowly lower the screw until the tail bearing contacts the bottom beam seat. It is strictly forbidden to start the spiral blade buried in the mineral sedimentation layer, otherwise the spiral blade, spiral shaft, reducer and gears will be damaged;

6. The load test run time is 8 hours.

     Spiral classifiers are widely used in ore dressing plants to be equipped with ball mills for closed-loop circulation to split ores, or for gravity. In the ore dressing plant, the ore and fine mud are classified, and the size classification of the pulp is carried out in the metal beneficiation process, and the operations such as desliming and dewatering in the washing operation are performed. The machine has the characteristics of simple structure, reliable operation and convenient operation.
