Abstract

The utility model discloses a novel vibrating mill for grinding various metals and non-metallic minerals, which comprises a mill cylinder body, a plurality of vibration exciters, a motor matched with the vibration exciters, an elastic supporting device and the like. The device has the characteristics of easy manufacture, light weight, less raw material consumption, large cylinder volume, large processing capacity, low investment cost and use cost and the like. The grinding device is used for grinding minerals in the industrial fields of metallurgy, building materials, electric power, chemical industry, ceramics and the like, and is efficient and energy-saving equipment capable of meeting the requirement of large-scale ore grinding production.

Description

A kind of novel vibrating grinding machine

The utility model relates to grinding attachment, the motor synchronizing vibrating mill that specifically a kind of multiple-motor that is applied to various metals of industrial circle grinding such as metallurgy, building materials, electric power, chemical industry, pottery and nonmetallic mineral drives.

As everyone knows, the grinding attachment that uses mainly contains two kinds at present: the one, and ball mill, its main body is that a level is installed on two large size bearings, can make the revolving body of low-speed motion by Motor Drive, and this class machinery cost height, volume is big, capacity usage ratio is low (only 5-7%); The 2nd, the vibrating mill that the monomotor of the forties invention in this century drives, its main body that is made of vibrator, cylindrical shell, frame etc. can be made approximate circular vibration in vertical plane under motor drives, because the material in the cylindrical shell is subjected to abrasive media acutely and the collision of high frequency is ground into powdery.But owing to be subjected to the restriction of aspect factors such as bearing load carrying capacity, shaft coupling transmission moment of torsion, structural strength, and the cylindrical shell volume is difficult to install abrasion-proof backing block for a short time, so be difficult in large-scale industrial production, apply, especially when manufacturing and designing the vibrating mill of big volume, big oscillation intensity, be restricted especially.

The purpose of this utility model is to release a kind of multiple-motor and drives self synchronous novel vibrating grinding machine, makes it to have simple and reasonable, reduces material consumption, can solve existing problem with grinding attachment existence deficiency.

The technical solution of the utility model is: the grinding mill barrel and be no less than 2 vibrator of on horizontal frames, being rigidly connected, lay resilient supporting unit under the frame; Every vibrator has a Motor Drive respectively, between motor and the vibrator flexible coupling is housed; When the grinding machine work housing was made dither on perpendicular, motor was not joined and is shaken.

Owing to adopted plural vibrator and had the motor more than two to drive in the such scheme, then overall efficiency height, output big, saved the energy.Motor is not joined to shake and has been significantly reduced the vibrational system mass of vibration; Every group of vibrator upper bearing (metal) load is little, then long service life.The grinding mill barrel volume is big, and inwall can be installed abrasion-proof backing block, so can design and manufacture the vibrating mill of big disposal ability, satisfies the needs of large-scale time in grinding production.

Below in conjunction with accompanying drawing and two embodiment the utility model is described in further detail.

Fig. 1 is the front view of first embodiment.

Fig. 2 is the scheme of installation of first embodiment of the utility model.

Fig. 3 is the front view of second embodiment.

Fig. 4 is the scheme of installation of second embodiment of the utility model.

In Fig. 2, be mounted with two grinding mill barrels 2 and two vibrators 3 on the frame 6, every vibrator 3 links to each other with a motor 4 by a flexible coupling 5.Frame is laid resilient supporting unit 16 times, see Fig. 1, above-mentioned parts constitute an elastic oscillating system, the motor 4 that is connected with every vibrator 3 is not joined and is shaken, be that it is not contained on the frame 6, and do not link to each other mutually between two exciter shafts, do not have machinery or electrical system to force its run-in synchronism measure between the motor reel.

Fig. 4 is second embodiment, be fixed with a capacious

grinding mill barrel

2 and 4 vibrators 3 on the frame 6, every vibrator 3 also by a flexible coupling 5 link to each other with a motor 4, frame lays for 6 times and is connected with resilient supporting unit 1, sees Fig. 3, above-mentioned parts constitute an elastic oscillating system.Motor 4 among this embodiment is not contained on the frame yet, does not join yet and shakes, and do not link to each other mutually between 4 exciter shafts, does not have machinery or electrical system to force its run-in synchronism measure between the motor reel.

Under the working condition, motor 4 is done gyration by the eccentric mass 8 that flexible coupling 5 drives on the vibrator 3, the moment of following that relies on elastic oscillating system itself to produce is eliminated the phase angle that produces in each eccentric mass 8 gyration process, reaches run-in synchronism.And be filled with wear-resistant medium 7 in the grinding mill barrel 2, and material adds in the cylindrical shell 2, because this moment, whole frame 6 was made dither under the drive of eccentric mass 8, material is violent and the collision and the abrasive action of high frequency are pulverized rapidly with regard to being subjected to wear-resistant medium 7.Grinding mill barrel 2 is owing to the effect of feed pressure, and powder material is then continuously discharged cylindrical shell 2.This vibrating mill both can thousand mill, but also wet-milling can also be divided into continous way or batch (-type) two classes.The complete machine comminution ratio is big, and the efficient height is a kind of energy-efficient fine grinding and the desirable milling equipment of ultra-fine mill.

Claims

1. novel vibrating grinding machine of forming by motor, frame and the grinding mill barrel of on frame, installing, vibrator, resilient supporting unit, at least 2 of quantity that it is characterized in that vibrator (3), and every vibrator (3) has a motor (4) to drive respectively, between motor (4) and the vibrator (3) flexible coupling (5) is housed.
