Ball mills operate either in open or closed circuit Open circuit operation is best utilized when: • Another stage of grinding follows the mill • Reduction ratio is small • Feed material is already fine and one pass through the mill produces the desired results • ,

Circuit Design While the optimum circuit design should be determined during testing of the ore, common flow sheets include: AG – SS (Single Stage) AG in closed circuit with a crusher; AG with a crusher and a ball mill; SAG – SS (Single Stage) SAG with ball mill/VERTIMILL®

Closed circuit crushing is recommended for single stage grinding as there is greater control over size of feed going to the one ball mill Open circuit crushing is advantageous when using two-stage grinding due to the ability of the rod mill to handle an over-size feed product

The circuit comprises a SAG mill, 12 m diameter by 61 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclon The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity

single closed ball mill circuit - Open Pillow Block Linear Ball Bearing (OPN) Inch Considered by many to be the default choice for linear motion applications, the round shaft reticulating linear ball bearing pillow block is a tried and tested option suitable for most linear motion applications

A 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 (COS) which provides surge capacity The grinding circuit is designed to produce a product size suitable for the downstream froth flotation process .

• The Bond Ball Mill Grindability Test determines the Bond Ball Mill Work Index used to determine net power requirements when sizing ball mills The test is a closed-circuit, dry grindability test It is run in a standard ball mill and can be performed at mesh sizes ranging from 48 mesh to 400 mesh Bond Ball Mill ,
