Bond Work Index Tests Grinding Solutions Ltd. Bond Ball Mill Grindability Test The Bond Ball Mill Work Index BBWi test is carried out in a standardised ball mill with a pre defined media and ore charge The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits The test requires a minimum of 10kg of sample that has been stage crushed to 100.
Read MoreA Bond rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of four laboratories that offer a rod mill work index test where the lining of the mill is either smooth or smooth with a small number of primitive lifters that do not constitute a wave liner one of.
Read MoreThe Bond ball mill work index test is thought to be additive because of its units of energy nevertheless experimental blending results show a non-additive behavior. The SPIR value is known not to be an additive parameter however errors introduced by block kriging are not thought to be significant . design of bond rod mill work index .

We offer a complete metallurgical testing investigative package from the early exploration phase through scoping pre-feasibility and feasibility to process development for flowsheet design and bankable feasibility.
Read MoreNumerically the work index is the energy required in kwht to reduce a given material from theoretically infinite feed sie to 80 passing 100 microns. The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test. Bond developed separate tests for the rod mill and the ball mill.
Read MoreThe Bond rod mill work index Wir is measured using Bonds standard rod mill grindability test which is conducted in locked-cycle mode to emulate the continuous closed-circuit operation. Besides the labor-intensive conduct of the test which typically requires from 5 to 10 cycles for reaching steady-state it normally requires 820.
