Four Measures to Improve the Separation Efficiency

The fundamental reason of low efficiency of the classifier spiral classifier is that fine heavy mineral particles and coarse light mineral particles settlement disorders in the grading process, and it produces drop phenomenon, and cause the large number of classifier grit folder fine and the overflow. You can consider the following measures to improve the classification efficiency: http://samantha0123.blogspot.com/ 
1. Change the traditional ways of discharge of spiral classifier , and adopt the bilateral row of ore, thus shorten the path of movement of mineral particles in the classifier and avoid pulp reflux, timely discharge the fine-grained overflow and shorten the settling time.
2. For the thin ore grains that sink to the bottom of the tank, we can add a stirring device in the bottom of the spiral classifier, and bring it back to the surface of pulp, and drain out with the overflow, and further reduce the thin particle in sand clamp and increase efficiency. Such as the Hongxing spiral classifier increases the return sand automatic lifting device, and cancel the configuration of Ball mill large spoon head, which greatly improve the grading efficiency.
3. We can also consider to change the traditional gravity sedimentation classification in the classification zone, and add a new field of force, such as an increase in the upper part of the grading machine sieve, secondary classification, this can increase the efficiency of the grading machine.
4. Spiral classifier grading efficiency affected by many factors in industry, in addition to the human factors, and it is related to the nature of the mineral particles, mainly refers to ore density, particle size, clay content, and related to the ore concentration, and also has relationship with hierarchical structure of operating parameters.
Spiral classifier is one of the devices of the beneficiation, spiral classifier is a device by taking advantage of the principle that Solid particles have different specific gravities, and thus precipitated in the liquid at different speeds.
