JK Bond Ball Mill Test - JKTech

JK Bond Ball Mill Test Since its introduction in the 1960s, the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw. Use of Work Index Along with comminution circuit design the work index parameter is widely used in tracking mill performance. Due to the age and lack of controls for the test,

Comminution testing - JKTech - University of Queensland

Jul 30, 2020  A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.

Modified Bond Ball Mill Work Index Test - What is this ...

a modified Bond ball mill procedure (Mod Bond) was developed by MinnovEX Technologies (now SGS) which requires 1.2kg of sample crushed at minus 3.35mm. The 1.2kg charge is milled with the standard Bond ball mill for a set time. A particle size analysis is performed on the feed and ground product, and a modified work index is calculated using a ...
