Detailed description of the invention
With reference to Figure of description 1 and accompanying drawing 2, a kind of large desulfurization ball mill of the present utility model is described in detail below.
A kind of large desulfurization ball mill of the present utility model, its structure comprises basic courses department 1, feed portion 2, barrel 5, driving section 6, cylinder sieve part 8 and at a slow speed transmission device 9, described feed portion 2, barrel 5, driving section 6, cylinder sieve part 8 and at a slow speed transmission device 9 are separately positioned on the top of basic courses department 1, the front end of described barrel 5 is provided with feeder 4, rear end is provided with discharging portion 7, between feed portion 2 and feeder 4, be provided with bearing portion 3, described transmission device at a slow speed 9 is connected with driving section 6, described driving section 6 comprises gear wheel 12 and pinion 14, described gear wheel 12 is arranged on the periphery at barrel 5 rear portions, described gear wheel 12 is meshed with pinion 14, described pinion 14 is arranged on pinion shaft 15, one end of described pinion shaft 15 is connected with transmission device 9 at a slow speed, the other end is connected with synchronous motor 11 by air clutch 10, described gear wheel 12 comprises two and half gears 16, two and half described gears 16 link together by bolt 13.
Described feeder 4 and discharging portion 7 comprise respectively end cap 17, and the root of described end cap 17 is set to knuckle.
The diameter of described barrel 5 is 4.0m, and length is 8.0m.
The basic courses department 1 of ball mill, it is the basis of supporting whole ball mill running; Feed portion 2, has conveniently adopted to trolley feed in order to overhaul; Bearing portion 3, supports whole ball mill body with it and rotates; Feeder 4, adopts end cap to add bushing for feeding form; Barrel 5, abrasive media-steel ball and material are loaded in the inside, and whole process of lapping just completes in cylindrical shell; Driving section 6, comprises gear wheel 12, pinion 14 and pinion device; Discharging portion 7, adopts end cap to add discharging lining form; Cylinder sieve part 8, filters screening materials carrying and impurity by it; Transmission device 9 at a slow speed, uses when maintenance ball mill.
