Xinhai has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications. Some of those applications are grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling oprations and more.
When the proportion of pebbles in the mill charge was low up to 30 , the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in the mill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to a ball mill to improve grinding efficiency. Published in
22/05/2019· Therefore, in the rolling ball mill, the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. However, the ball diameter is too small to wear too fast, and it is also difficult to discharge due to the small gap of the ball. Therefore, the ball used in wet grinding the mixture
c Closed Circuit Grinding Also closely related to the ability of a ball mill to perform most effectively on a particular material size distribution is the increased grinding efficiency observed with increased circulating load and classifier efficiency Increased circulating load decreases overgrinding and provides the media with an effectively narrower size distribution to work on

A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive central gear unit: helical gear unit orary gear unit or

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds.
Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, AG mills, or SAG mills. Figure 8.11.
