Abstract

The utility model relates to a lattice type grinding machine composed of a front end cover, a cylinder body, a rear end cover, reinforcement lattice grid plates, etc. The lattice type grinding machine is suitable for grinding various metallic or nonmetallic materials. Since the lattice type grinding machine is provided with the lattice grid plates having mesh ribs, the use cycle of the lattice grid plates is increased doubly. The lattice type grinding machine has thin thickness, light weight, easy replacement, no blockage and little medium consumption.

Description

Lattice type grinding machine

The utility model relates to a kind of novel lattice type grinding machine that is used for metal or non-metallic material grinding.

The employed common flase floor of used lattice type grinding machine is plate-like structure as shown in Figure 1, and grinding charge material and milling medium directly act on level and smooth flase floor surface in the work, causes the flase floor quick abrasion, the life-span is low, life cycle is short; Be forced to increase flase floor thickness for prolonging life cycle, bring again weight big, change difficulty, little, the easy obstruction of grid plate hole tapering; Simultaneously, the attenuation because flase floor weares and teares fast in the use, the grid plate hole constantly increases, even the mill leakage, brings the milling medium loss to increase.

The purpose of this utility model is at above problem, start with from seeking rational flase floor structural type shape, improve its wearability, reduce the rate of wear, prolong life cycle, make flase floor reach in light weight, thin thickness, easily change, wear-resistant, do not stop up, dielectric dissipation is few.

The utility model is seen accompanying drawing 2, mainly is made up of drive end bearing bracket 1, cylindrical shell 2, reinforced grating plate 3, rear end cap 4 etc.The reinforced grating plate 3(that has a netted rib is as shown in Figure 3) have following characteristics: 1, changed the plate armature of common flase floor, on the basis of plate armature, increased netted rib, the spacing of rib is 100～400 millimeters; Height H is 40～160 millimeters; 2, thin thickness, the plate part thickness B of perforate has only about 50% of common flase floor; 3, grid plate hole tapering is big, improves 1～2 times than common flase floor, reaches 12～20 degree; 4, the flase floor hole width reduces about 20%.The grinding charge material enters in the grinding mill barrel 2 through the quill shaft of rear end cap 4 in the work, is pulverized under the impact grinding effect of milling medium, and qualified products are discharged by the quill shaft of drive end bearing bracket 1 by the perforate of reinforced grating plate 3.

The utility model has been owing to adopted the reinforced grating plate, thereby has following effect: 1, wear-resistant, life cycle is long, and the reinforced grating plate is compared with common flase floor, and life cycle prolongs more than one times, reduce overhaul the replacing time, fall lower steel consumption, the raising operating rate.2, in light weight, easy replacing, unit flase floor weight reduces more than 10%.3, reinforced grating plate perforate tapering is big, thereby does not have clogging.4, in the whole life cycle, have only rib to be worn, and wear and tear hardly in the plate part surface of perforate, thereby overcome, cause Kong Bianda, even mill leaks the milling medium loss that causes because of the flase floor wear down.Simultaneously,, also reduce the residual ball size of discharging under the normal operation situation, improve the steel ball utilization rate because reinforced grating plate hole width reduces than common flase floor.

At the utility model, the specific embodiment that the inventor did is as follows: the ball mill specification is φ 3.2 * 3.1M, handle the Anshan type lean hematite ore, reinforced grating plate plate part thickness B is 50 millimeters, the rib height H is 70 millimeters, the rib spacing is 200～300 millimeters, the flase floor perforate: import b ₁Be 16 millimeters, outlet b ₂Be 28 millimeters, tapering is 13.5 degree.The reinforced grating plate adopts the potassium steel casting technique to produce, and utilizes bolt, press strip to be fixed on the grinding machine front end cross.This utility model is used on 11 identical grinding machines, and (thickness B is 90 millimeters, aperture widths b with common flase floor with material is housed ₂Be 20 millimeters, b ₂Be 30 millimeters) grinding machine compare, the flase floor life cycle was brought up to 18 months by past 8～9 months, annual 28 tons of the metal consumptions of saving are worth 10.3 ten thousand yuan; Save 271.17 tons of steel balls, be worth 27.2 ten thousand yuan, only can save and be worth 37.5 ten thousand yuan these two every year.

Claims

1, a kind of lattice type grinding machine of being made up of drive end bearing bracket 1, cylindrical shell 2, rear end cap 4 etc., its major technique feature is to have the reinforced grating plate 3 that has netted rib.

2, lattice type grinding machine according to claim 1 is characterized in that the netted rib spacing of muscle flase floor 3 is 100～400 millimeters, and the rib height H is 40～160 millimeters.

3, according to claim 1 and 2 described lattice type grinding machines, the tapering that it is characterized in that the flase floor perforate is 12～20 degree.
