WhatsApp: +86 18838072829CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
WhatsApp: +86 18838072829Fig. 1 shows the SEM micrographs of the ascast, ball milled and cryomilled samples of TiFe+4 wt.% Zr alloy. The ascast particles have sharp edges, resulting from the grinding procedure performed using a mortar and a pestle. After only 5 min of ball milling, the particles are much smaller and are characterized by round milling resulted in agglomerations of smaller particles.

WhatsApp: +86 18838072829Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
