Salient Features:
1
 Basic arrangement with the closed milling path is used especially for crushing limestone for sintering purpose and for grinding similar types of material. Fineness of the outlet product thus obtained is of 0 ÷3 mm with grate slots of 10 mm.
2
 A Closed milling path armour removed over the dividing level is used for materials with higher moisture content, for example for limestone up till 6% of H2O, and in other cases when a partial glueing of grate slots occurs.
3
 Arrangement with the open milling path is used for crushing bituminous coal for coking and for coarse grinding of limestones, of cement related raw material convenient for the technology of crushing in hammer mills. Achieved fineness of coal is of 0 ÷ 3 mm for limestones for cement related raw materials and for other appropriate materials it is of 0 ÷ 10 mm.
4
 Arrangement with an open milling path at a random place of the milling path. It is used for less easily crushable materials mentioned in the previous variant.
5
 Grinds almost anything!
6
 Large output, to 800 lbs. /hr
7
 Large effective screen area with screens from 35 meshes to 100 mm!
8
