Ball mill design for long life and minimum maintenance
Zhongde overflow ball mill sizes range from 5ft to 8ft,with 75HP to 30’ ×41’,and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drivers.Our mills incorporate many of the qualities which have made Zhongde name famous since 1959.
These heavy-duty machines are designed for long time and minimum maintenance.
Variation of the standard designs are available to suit any appropriate application. These may include but not be limited to grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling operations, or pebble milling.

Application:
A ball mill grinds ores and other materials to a typical product size of 325 mesh or finer.
The feed to a ball mill is prepared by:
· Single or multistage crushing and grinding
· Crushing, screening, and/or rod milling
· Primary crushing and autogenous/semiautogenous grinding
Normal feed sizes:
· 80% passing 1/4 "(6mm or finer) for hard ores
· 80% passing 1 "(25mm or finer) for soft ores
· (Larger feed sizes can be tolerated depending)
The length to diameter ratio of cylindrical mills is range from 1 to 1 to 3 to 1. When the L/D ratio is 2 to 1 or greater, we refer to the mill as a Tube Mill.
