Void Traces are a resource found in Void Fissures, used to refine Void Relics or create Dragon Keys.. Acquisition [edit edit source]. Void Traces are primarily obtained by collecting Reactant, which occasionally drops from Corrupted enemies (including those who turn Corrupted during the mission) provided there is a Void Fissure present. Reactant is collected to crack open a Void Relic, but

احصل على السعرThe ball mill is the key equipment to crush the material after being crushed. This type of mill is equipped with a number of steel balls in its cylinder as grinding medium. When the barrel rotates, the grinding medium is attached to the wall lining of the barrel due to inertial centrifugal force.

احصل على السعرJul 02, 2008 · To obtain the net torque drawn by the tumbling balls, the torque of the empty mill (which represent bearings losses, etc.) must be deducted from the gross torque readings. The ball load (9.5 kg) filled the mill to 45% of its volume. The feed charge was held constant at 874 g, which occupied 80% of the void space between the balls at rest.

احصل على السعرIn the ball-and-race mill (Fig. 13.3), balls are held between two races, much like a large ball bearing.The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.
