A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
Maximum rod length is about 6 to 7 metres otherwise there is a risk of the rods drum diameter is limited to 06 or 07 times the length of the g principle of rod mill the rod mill is a horizontal rotating device transmitted by the outer materials are transferred to the grinding chamber through the quill

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore The rod charge must be maintained in good working condition and broken and worn rods must be removed
A ball mill is a type of grinder used to grind and blend bulk material into QDsnanosize using different sized balls The working principle is simple impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell

It may sometimes be recommended also for finer grinding Within these limits a rod mill is usually superior to and more efficient than a ball mill The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill resulting in selective grinding carried out on the largest particle sizes
The faster the mill speed the greater the wear on the rods and liners So the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill
