Ball Mill Feeders Mineral Processing & Metallurgy

Oct 22, 2016 SCOOP FEEDERS. The single scoop feeder provides a simple means of picking up and delivering the entire amount of feed to the grinding mill. These feeders are generally used where the size of feed will be relatively fine. The internal construction of the feeder is such that a spiral carries the feed into the trunnion liner.

Ball Mill Explained saVRee

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged.

Grinding Mills Metallurgist & Mineral Processing Engineer

Ball mills are built in Overflow and Diaphragm types. In the Overflow mill the material is discharged by new feed moving into the mill and displacing a mixture of solids and water being ground within the mill. The diaphragm arrangement in a ball mill is a positive means of pumping pulp or dry material out of the mill.

PERI™ AutoCharge Mill Grinding Ball Charging System

Feeder. The AutoCharge feeder continuously charges balls from the storage bin to the mill. The feed wheel picks up balls in each flight and when they pass the top-centre of the wheel, they roll off into either the counting chutes or the weighing module before dropping directly into the mill feed stream.

Scats production in overflow ball mill Grinding

Sometimes, you solve scatting by charging the ball mill correctly (I saw cases where the mill was up to 15% under power). Other times, you need to enlarge the ball size diameter ie: using a 75 mm ball instead is 35 mm. Other times, you must control and reduce the feed size (crushing circuit product). Therefore, no, changing to a grate discharge
