  • Batch Ball Mill For Open Or Closed Circuit Grinding

    Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit).The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.A belt scale mounted on the recycle conveyor monitors the SAG mill recycle rate. The target SAG grind is 80 passing 1,381 microns.Secondary grinding is performed in a ball mill. The ball mill operates in closed circuit with hydrocyclones. Ball mill discharge is combined with vibrating screen undersize in the cyclone feed pump box and ispumped.

    Dec 12, 2016 Ball Mill Power Calculation Example. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80 passing inch (6350.Milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is.Jun 06, 2016 By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling while convenient, this has the disadvantage of not controlling the top size of feed to the ball-mill circuit.
