Abstract

The utility model relates to a ball mill for milling raw, sinter suitable for ore dressing in a mine and cement producing in a cement plant, comprising a roller in the existing technology, a reduction device, a motor, a flange fixed outside the roller discharge axle, a connector provided with flanges at the two ends and at least two uniformly-distributed discharge ports on the middle tube wall and connected on the roller by the flanges and a rubber cushion between the flanges between the connector and the reduction device. The roller, connector, reduction device and motor are arranged on a same axle to simplify the structure, reduce the frictional resistance and has smaller resistance, saved labor and not-easily worn parts, long service life, stable operation, above 30% power saving effect compared with the ball mill of patent 200720016153.0. Using 2130 type ball mill as example, the prior mated motor is 210kW and the mated motor of the utility model is 130kW to easily drive and 80kW is saved for each hour.

Description

Ball mill

Technical field the utility model relates to suitable mine ore dressing, a kind of ball mill that ball milling was given birth to, grog is used during the cement plant produced.

Background technology is 2007200161530 as far back as the patent No. of inventor's application, just solved the general milling machine in the patented technology of " ball mill " by name because the columniform cylinder in its structure, need certain gradient during installation, the feed inlet end height, discharge port end is low, because cylinder wall and liner plate are parallel with the axis of cylinder, it is insufficient to have occurred ball milling in the production, the phenomenon of running material from discharging opening is serious, and it is big to form the partial circulating amount, has caused disadvantages such as human and material resources waste.Though this ball mill has overcome general milling machine above shortcomings, but we find in the practice, because the patent No. is being connected not on same horizontal axis of pinion on gear wheel and the reductor of structure intermediate roll end of 200720016153 ball mills, so it is many also to exist the structure link, frictional resistance is big, and parts are easy to wear, and service life is short, move steady inadequately, unfavorable factor such as power consumption is big.

Summary of the invention is 2007200161530 ball mill above shortcomings at the patent No., and the utility model will provide a kind of structure simpler, and frictional resistance is little, operates steadily long service life, the ball mill of power saving.The design of the utility model ball mill is: to the existing patent No. is that 2007200161530 ball mill improves, remove the layman's gear of original structure intermediate roll end and the pinion of reductor, its concrete structure has comprised cylinder, reductor, the motor of prior art, and outside cylinder discharging axle mounting flange, be connected two ends with cylinder by flange and having the connector that is evenly equipped with 2 above discharge gates on flange, the middle tube wall at least, between connector and reductor flange connecting, be provided with rubber cushion.Cylinder, connector, reductor and motor in the utility model ball mill structure are all on same axis, simplify the structure, reduced frictional resistance, it is that specific resistance is little mutually for 2007200161530 ball mill with the prior art patent No., laborsaving, mechanical part is not easy to wear, long service life, operate steadily, power savings is more than 30%.With one 2130 type ball mill is example, and original necessary electromotor is 210KW, and necessary electromotor of the present utility model if 130KW just can easily drive, 80KW per hour can economize on electricity.

Appended drawings is the structural representation of the utility model ball mill.

The specific embodiment has further understanding for the structure to the utility model ball mill, and details are as follows in conjunction with the accompanying drawings:

With reference to accompanying drawing, the structure of the utility model ball mill has comprised the cylinder that is taper type 1 among the figure, the flange of outside cylinder 1 discharging axle, fixing 2, two ends that are being connected with cylinder 1 by flange have the connector 4 that is evenly equipped with 2 above discharge gates 3 on flange, the middle tube wall at least, the reductor 5 that is connected with connector 4, the rubber cushion 6 that is provided with between connector 4 and reductor 5 flange connecting is with the motor 7 that is being connected with reductor 5.Its intermediate roll 1, connector 4, reductor 5 and motor 7 all are located on the same axis 8.

Claims (2)

1. ball mill, it includes cylinder (1), reductor (5), motor (7), it is characterized in that it also includes flange (2) fixing outside cylinder (1) discharging axle, two ends that are being connected with cylinder (1) by flange have the connector (4) that is evenly equipped with 2 above discharge gates (3) on flange, the middle tube wall at least, and the rubber cushion (6) that is provided with between connector (4) and reductor (5) flange connecting.

2. the described ball mill of root a tree name claim 1 is characterized in that cylinder (1), connector (4), reductor (5) and motor (7) all are located on the same axis (8).
