Classifier and screen performance formula: Classification efficiency is generally defined as the weight ratio of classified material in the sized overflow product to the total amount of classifiable material in the classifier feed, expressed as a percentage. For two-product separations, the general form used is:
NEYRTEC MINERAL dewatering screens are used to perform a dewatering operation that considerably reduces the moisture content of materials. This step facilitates the handling and the storage in heap of materials while optimizing recycling of cleaning water. The vibration created by the 2 out-of-balance motors improves water flow between the materials/grains to be treated.
