Should Always Check the Damage of Screw Classifier

Screw Classifier ,this is spiral classifier, screw separator, which is widely used to form a closed cycle process to split mineral sand with cone ball mill in ore dressing plants, grade ore and fine mud in the gravity ore dressing plant, or for the pulp size classification in the metal beneficiation process, as well as desliming and dehydration in washing operations. Spiral classifier has the characteristics of simple structure, reliable work, convenient operation, etc.




Spiral classifier is a type of classifying machine that classifies materials based the principle that the solid particles with different sizes and proportions have different falling speed in the liquid, and fine ore particles float in the water and coarse ore particles sink to the bottom of the chute and the coarse ore particles are pushed by the spiral to the upper part and discharged. Classifier is one of the important equipment in ore dressing process, and the most commonly used type is spiral classifier, which is also called screw classifier. Spiral classifier carries out mechanical grading by using the principle that different proportion of solid particles have different precipitation rate. It can filter powder in the small ball mill, and then screws the coarse material into the feeding inlet with by the on-chip spiral vane; the fine material will be discharged from the overflow pipe.

The spiral calssifier is one of the important ore processing plant equipment, so we should maintain it well, there are three tips for screw classifier maintenance:

1. Lubrication points are fueled by sodium or calcium based grease;

2. You should always check the damage of bearings and seals, and replace them timely;

3. Bearings must be lubricated every 4 hours to keep its sealing performance.
