    Current screen capacity calculations do not take into consideration enough of the factors affecting screen efficiency. The old formulas were designed to keep calculations short and manageable for manual calculation. The common use of computers in today’s world makes it possible to do more complex screen capacity calculations in much shorter time.

    trommel screens used in the processing of munici­ pal solid waste (MSW). The study had a twofold aspect, namely, the development of a theory to describe particle dynamics and screening perfor­ mance, and simultaneously the acquisition of field test data through use of two trommel screens that differed from each other in dimensions and design.

    A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit. A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 5/8″ or 16mm In the image case below, strangely enough, is the mill shell liner and discharge grate manufacturer. The grates it provides to this Cu/Pb ...

    May 07, 2013· After adding material to the trommel (I’m guessing around 100 lbs of material) the wheels slipped on the trommel. I could manually rotate the trommel by standing at one end of the trommel and rotating by hand. When I did this I noticed the material tended to cling to the inside of the trommel until the trommel had rotated about 60 degrees.
