Bond Ball Mill. 5 October 2015. LABPILOT PLANT EQUIPMENT. This 12 x 12 ball mill is universally used for grindability testing and determination of the Bond Work Index. Mill comes complete with ball charge and control panel with automatic revolution counter.
Dec 17 2018 Applicable reasonably in conventional ball mill and rod mill grinding holds good for 5 cm – 50 . The power input is computed from Bond work index feed and product particle sizes by W 10 Wi P0.5 - 10 Wi F0.5 9c W power input ; Wi work index ; F 80 passing size of feed ; P 80 passing size of product .
Grams per revolution Gbp is the ball mill grindability. The ball mill work index Wi kWhshort ton is calculated from the following equation Bond 1961:1 The mill should be cleaned by either blowing air into it or wiping the interior with a cloth and or brush. The FC Bond ball mill

Limestone bond work index hammer mill - MC Machinery. During the Bond work index value determining changes in the composition of the grinding products and circulating mill charge were monitored. Keywords. limestone bond work index Mining. Apr 17 2013 Ball Mill Bond Work Index for Limestone Ore Beneficiation Plant.
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 passing size of 3.35 mm. Any ...
The rationale of the Bond work index was the crack theory that the length of the new fracture produced by the ore grinding was proportional to the input energy . According to the requirement of the Bond work index the standard work index ball mill Φ305 305 mm has no liner plate.
The work index values of the Magdalinovic method agree with this average Bond work index because the method does not simulate the recycling of harder components into the mill charge. On the other hand the work index obtained using the standard Bond test shows the weighting of the work index towards the harder component as a result of the ...
This work highlights the importance of maintaining a competent ball charge in a mill. ... corresponding Bond work index Wi and grindability index G of these materials. ... draw of a 5-m ball ...
Where operating work index kwht isWiop mill power draw kw isW Q is mill throughput th andP80F80 are respectively mill product and feed size distributions. Operating Bond index is not comparable to laboratory standard Bond index; therefore a few correction factors should be multiplied to obtain of corrected operating Bond index13 17.
