 · Typical size ranges would start with run-of-mine coal feeding to the primary sizer at 2000 mm, and reducing to 350 mm. The secondary sizer would receive this coal and discharge at a nominal 125 mm, followed by a tertiary sizer/screen combination to generate a 50 mm topsize preparation plant feed (FLSmidth, 2011). 9.2.3. Hammer crushers

When the run of mine product is conveyed directly from the mine to the crusher, the feed to the primary crusher passes under a magnet to remove tramp steel collected during the mining operation. A grizzly screen is placed between the magnet and the receiving hopper of the crusher to scalp (remove) boulders larger than the size of the gape.

Stone removal from the run-of-mine is the operation that allows for the initial sepa- ration of some of the waste grains and, as a result, to reduce load to the technological line of coal processing.
