most rod mill applications involve wet grinding where material is reduced in size from crusher product size to a size suitable for ball mill feed. to avoid breakage or tangling of rods, the l/d ratio of rod mills is kept within the limits of 1, 3/1 to 2/1.
ball mill is a horizontal rotating device transmitted by outside gear. material is transferred to grinding chamber through the quill shaft uniformly. there are ladder liner and ripple liner with different specifications of steel balls in the chamber.
the ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non ferrous metals.
ball mills. christian pfeiffer design and build grinding plants and equip them with all the right features or auxiliaries. their separators ensure even greater efficiency of your processes. and from the first idea to the last screw, they also design and build entire ep or epc
a planetary ball mill consists of at least one grinding jar arranged eccentrically on a wheel that spins in the opposite direction to the grinding jar(s). this releases high dynamic energies resulting in a fine grinding of the sample.
