Grinding Circuit - an overview | ScienceDirect Topics
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. (Reversing direction evens out wear on liners with symmetrical profile and prolongs operating time.) The ...
Circuit Grinding For Ball Mills - dutch-alejandro.nl
The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load. The standard procedural outline of the test is stated in (Bond) 1961. The work index for a ball mill, Wi, is then calculated from the following equation. [7] where P is the closing sieve size ( m), Gbp is the grindability (net g/rev.), F80 and P80 are the 80% passing size of the ...
