The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.

parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose.

at a minimum of 3 points along the mill. Excess of slurry could also be estimated. To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of

achieve complete combustion. Like fuel/air mixing, the required residence time is least for gases and most for large solid fuels: • Gases and fine liquid sprays- 10 - 20 ms burnout • Pulverized fuel (coal, sawdust)- 1 s burnout • Stoker coal, bark, wood waste, trash- 10's of minutes

A ball mill is a large cylindrical tube partially filled with steel balls. The ends of the steel cylinder are attached to trunnions that are supported on journal bearings. As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom. The raw material is fed into the ball ...
