Particle Size Reduction with Lab Mills & Crushers .Deze pagina vertalen

Which type of mill is used for a particular particle size reduction task always depends on the breaking properties of the sample material. Size reduction machines for large particle sizes above 40 mm are known as crushers or shredders while particle sizes below this are processed with mills.

Fine Refining Ball Mill - Royal Duyvis Wiener B.V.Deze pagina vertalen

Description. The principles of grinding are well established: the pre-ground liquor is pumped through the ball mill's grinding vessel in one or more stages. The refining action is accomplished by a special shaft with agitator arms and diverters rotating in a vertical jacketed grinding tank, which is filled with hardened steel balls. The various layers of grinding elements move in the same ...
