The effect of ball mill on the morphological and structural features of cellulose has been described by Okajima and coworkers 20 They treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for 4–8 hours in dry and wet conditions with three solvents (water, toluene, 1butanol)
Procedure for determination of ball Bond work index in the
A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO, 2006) This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required
Bond Work Index an overview ScienceDirect Topics
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 310), a question arises as to whether this practice will alter the ball mill work index (BW
Comminution and classification technologies of iron ore
Product from the secondary ball mills is classified by cyclones and cyclone underflow is returned to ball mill feed and cyclone overflow reports to final product which has 80% passing 105 microns After two stage of deslime cyclones, ore is sent for the reverse flotation to produce final product >65% iron for pallet production
