Ball Mill Explained - saVRee

If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

11.21 Phosphate Rock Processing

Primary size reduction generally is accomplished by crushers (impact) and grinding mills. Some classification of the primary crushed rock may be necessary before secondary grinding (rod milling) takes place. The ground material then passes through hydrocyclones that are oriented in a 3-stage countercurrent arrangement.

Choosing the correct mill screen for your bulk powder solids

They are commonly used for wet milling in pharmaceutical processing - the hole size depends on the moisture and density of the wet mass. By conditioning the wet material it improves the drying efficiency and reduces the production of fines. Due to the high open area they allow for processing of wet material without any screen blinding.
