Introduction of Spiral Classifier. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting, a partially drained fraction containing the coarse material, called the underflow; and a fine ...
