Abstract

The utility model discloses a globe mill and includes a power device, a transmission gear, and a roller. A scaleboard consisting of a plurality of small metal plates is fixed onto and covers the inner wall of the roller through bolts, the scaleboard composed of the metal plates forms ring rolling paths on the inner wall of the roller, a metal ball is arranged in the rolling paths, a pylome is formed between the two rolling paths by a separation wall, the height of the separation wall is 40 percent of the diameter of the metal ball, the diameter of the metal ball is 30 percent of the diameter of the roller, the metal ball matches with the rolling paths with no clearance, and the surface finish quality of the rolling paths from a feed port to a discharge hole is respectively a rugged face, a microrugged face and an even surface. The utility model has simple structure, adopts a structure of single ball and single track, and the crushing process can achieve the effects of grinding, slipping, pressing, milling and so on, thus ensuring processing quality, improving production efficiency and reducing energy loss.

Description

A kind of ball mill

Technical field:

The utility model relates to a kind of ore process equipment, particularly relates to a kind of ball mill.

Background technology:

At present, mine industry comprises roughing and retrofit to the processing of ore, roughing adopts hammer-crusher ore reduction to be become a certain size specification, adopt ball mill that ore is carried out retrofit then, ore is processed into fine powder, present ball mill, its structure comprises motor, drive mechanism, the charging aperture at cylinder and cylinder two ends, discharging opening, it in the cylinder some, Metal Ball not of uniform size, rotation by cylinder makes the continuous motion collision of Metal Ball, come the ore in it is clashed into the broken processing of grinding with this, the ball mill working (machining) efficiency of finding this structure in the long-term production process is too low, and reason is that contact-making surface is little between Metal Ball and the ore, mainly grinds broken by bump, prolonged running time, power consumption is high.

Summary of the invention:

The utility model is at the deficiencies in the prior art, a kind of ball mill is provided, technical problem to be solved is by changing the structure in the cylinder, increase the size of Metal Ball, reduce the quantity of Metal Ball, make shattering process to grind, consult, press, mill is main, improve crudy and efficient, cut down the consumption of energy, technical solution adopted in the utility model is as follows: the utility model comprises power set, transmission device, cylinder, on the inwall of its intermediate roll by bolting by the liner plate of forming by the plurality of small blocks metallic plate that inwall is covered, it is characterized in that the liner plate that metallic plate is formed forms ring raceway on the inwall of cylinder, establish a Metal Ball in the raceway, form through hole by partition wall between adjacent two raceways, the height of partition wall is 40% of a Metal Ball diameter, and the diameter of Metal Ball is 30% of a diameter of cylinder, cooperate for no gap between Metal Ball and the raceway, and raceway face fineness is followed successively by matsurface from charging aperture to discharging opening, slightly rough surface and even surface.

Compared with prior art, the utility model is simple in structure, adopts single ball monorail structure, and several effects such as shattering process can realize grinding, consults, pressure, mill can be guaranteed crudy, enhance productivity, and cut down the consumption of energy.

Specific embodiments:

The utility model comprises roller tube 1 and liner plate 2, and Metal Ball 3, liner plate is assembled into, every part is fixed on the cylindrical shell by bolt 7, form raceway 4, the quantity of raceway is looked the length of cylinder and the diameter of Metal Ball is determined, the diameter of Metal Ball is 30% of a diameter of cylinder, only establishes a Metal Ball in each raceway, forms through hole 6 by partition wall 5 between adjacent two raceways, the height of partition wall is 40% of a Metal Ball diameter, as for diameter 1.8m, the cylinder of long 6m can be established 6 raceways, the diameter of Metal Ball is 0.54m, and the height of corresponding partition wall is 0.216m; For the cylinder of 1.5 meters of diameters, 3 meters of length, can establish 3 raceways, the diameter of Metal Ball is 0.45m, the height of corresponding partition wall is 0.18m.

Claims

1. ball mill, comprise power set, transmission device, cylinder, on the inwall of its intermediate roll by bolting by the liner plate of forming by the plurality of small blocks metallic plate that inwall is covered, it is characterized in that the liner plate that metallic plate is formed forms ring raceway on the inwall of cylinder, establish a Metal Ball in the raceway, form through hole by partition wall between adjacent two raceways, the height of partition wall is 40% of a Metal Ball diameter, the diameter of Metal Ball is 30% of a diameter of cylinder, cooperate for no gap between Metal Ball and the raceway, and raceway face fineness is followed successively by matsurface from charging aperture to discharging opening, slightly rough surface and even surface.
