In a reverse closed-circuit ball mill-classifier circuit the new feed enters the classifier, the classifier oversize is fed to the mill, the mill discharges to the classifier, and the classifier undersize is the finished product of the grinding circuit. the following are the sieve analyses of the streams of such a circuit.
the circuit comprises a sag mill, diameter by 6.1 length two pebble crushers, and two ball mills in parallel closed with cyclones. the sag mill is fitted with a MW gearless drive motor with bi-directional rotational capacity.
grinding circuit. there are different points for measuring density in the grinding circuit. one of the applications is to monitor the dillution of material in the ball mill discharge, to improve the efficiency of the process.
upgrade to combi-grinding with high-pressure grinding rolls In this case, the hpgr will be installed before the ball mill and replace the first ball mill chamber, increasing the length of the second chamber. upsides are good energy efficiency and a high output increase.
grinding circuit the grinding circuit consists of a conventional sab circuit with a 3.73 3,356 kW sag mill and a 5.49 8.84 4,474 kW ball mill in closed circuit with hydrocyclones sag mill throughput typically ranges from 473 515 tph depending on the ore type being processed.
third ball mill takes a split of feed from each module to assist maintaining a target product size. both modules are fed from the same primary crushing circuit via a coarse ore stockpile which provides surge capacity. the grinding circuit is designed to produce a product size suitable for the downstream froth flotation process. user
In the grinding circuit possible installation points are in the ball mill discharge and feed cyclone feed, overflow and underflow. measuring points in the grinding circuit. the grinding circuit can be considered as the first step of a processing plant, therefore, operators need to have a good control over it.
