The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
Ball mills have been successfully run at speeds between60and90 percentof critical speed, but most mills operate at speeds between65and79 percentof critical speed. Rod mills speed should be limited to a maximum of70% of critical speed and preferably should be in the60 to 68percent critical speed range.

Rodmillsare used in an open circuit between crushing and theball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rodmillsare preferred overball mills.Get A Quote
