The grinding mechanism takes place within the falling and sliding grinding media. The feed material enters at one end of the ball mill and travels horizontally through the grinding media, discharging at the opposite end of the mill passing through a discharge grate and normally to a high effeciency air classifier for product classification.
Designing grate discharge Ball mill with filter attached at the output line give product in uniform appearance this machine has very stable performance that it is very easy to operate . Grinding procces by grate discharge ball mill can be operate in wet and dry process. Design of this machine aimed to obtaine 30 ton per hour capacity product.

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.
The Smallest Mobile Ball Mill With Input And Grate discharge ball mill for phosphate for gold discharge ball mill for magnesite high frequency grate discharge ball mill for fluorite heavy he reasons 2 our grate discharge ball mill exported to more than 180 countries and regions there are a lot of overseas offices and branches you can rest assured purchase goethite high quality
#0183;#32;Discharge grates play an important role in determining the performance of autogenous, semiautogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate designopen area and position of apertures, as well as the performance of the pulp lifters.
Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills
Grate Ball Mill Grate Type Ball Mill Grate Discharge Ball . Advantages of grate ball mill. 1. As the ball mill transmission adopts rolling bearing instead of sliding bearings friction is greatly reduced with easy startup and significant saving energy 2. Highperformance rotary valves and airlocks for metering .
