Abstract

The utility model discloses a ball mill which comprises a ball mill cylinder and a transmission device connected with the same. A lining board is arranged inside the ball mill cylinder. A lining of sound-absorbing material is disposed between the outer wall of the lining board and the inner wall of the ball mill cylinder. The inner wall of the lining board is provided with lifting grooves. The material grinding efficiency of the ball mill can be improved effectively, and noise can be reduced effectively.

Description

A kind of ball mill

Technical field

The utility model relates to a kind of ball mill, is specifically related to a kind of ball mill that can improve inner steel ball falling speed and reduction noise.

Background technology

Ball mill is after material is broken, the key equipment of pulverizing again.It is widely used in production industries such as non-ferrous metal ore.Centrifugal force when existing ball mill general using is rotated promotes the steel ball of inside, pulverizes through the interaction partners material between steel ball and the material.But the hoisting power of centrifugal force is limited,, will fall because of the gravity effect also before the no show top at steel ball, can't reach maximum common mill speed.Because steel ball to the enormous impact power and the frictional force of ball mill barrel, has produced serious noise pollution, and the speed of steel ball is big more, noise is big more simultaneously.

Summary of the invention

The purpose of the utility model is the defective that exists in the prior art in order to solve, and a kind of ball mill that can effectively promote the steel ball height and reduce noise is provided.

In order to achieve the above object, the utility model provides a kind of ball mill, comprises ball mill barrel and the transmission device that links to each other with ball mill barrel; Be provided with liner plate in the ball mill barrel; Be provided with the sound-absorbing material lining between said liner plate outer wall and the ball mill barrel inwall; The inwall place of said liner plate is provided with the lifting groove.

Further improvement to the utility model is: liner plate outer wall place also is provided with the sound absorption groove, and sound-absorbing material layer is housed in the groove.

Above-mentioned lifting groove two sides and ball mill barrel direction of rotation are 60 ° of angles.

Transmission device comprises motor, the belt pulley that links to each other with motor and driving-belt; Said ball mill barrel links to each other with belt pulley through driving-belt.

The utility model ball mill is compared prior art and is had the following advantages: utilize the lifting groove with the ball mill rotation the inner steel ball of ball mill to be risen to the ball mill top, increased the speed that steel ball falls, improved its efficient that grinds altogether thus.Utilize sound-absorbing material layer and the interior sound-absorbing material lining of sound absorption groove to absorb and consume the vibrational energy of liner plate and cylindrical shell effectively simultaneously, thereby reduce the noise of ball mill.

Description of drawings

Fig. 1 is the utility model ball mill structural representation.

Fig. 2 is the cutaway view of ball mill barrel among Fig. 1.

Among the figure, the 1-ball mill barrel, the 2-belt pulley, the three-dimensional transmission bracket of 3-, the 4-motor, the 5-driving-belt, 11-promotes groove, 12-sound-absorbing material lining, 13-liner plate, the 14-groove that absorbs sound, 15-sound-absorbing material layer.

The specific embodiment

Below in conjunction with accompanying drawing the utility model ball mill is elaborated.

As shown in Figure 1, the utility model ball mill comprises ball mill barrel 1, belt pulley 2, three-dimensional transmission bracket 3, motor 4, driving-belt 5.Motor 4 is placed on the lower floor of three-dimensional transmission bracket 3; One group of belt pulley 2 is laid on the upper strata of three-dimensional transmission bracket 3; Belt pulley 2 links to each other through driving-belt 5 with motor 4; Driving-belt on the ball mill barrel 1 links to each other with the belt pulley 2 on three-dimensional transmission bracket 3 upper stratas, and motor 4 drives ball mill barrel 1 through driving-belt 5 and rotates.Ball mill barrel 1 is provided with charging aperture and discharging opening (not shown).

Be provided with the liner plate 13 that band promotes groove 11 in the ball mill barrel 1; Referring to Fig. 2; This lifting groove 11 is located at the inwall place of liner plate 13; It is perpendicular with the diameter of crossing this bottom centre to promote groove 11 bottoms, and promotes groove 11 both sides inwall and bottom along the circumferential direction and be 60 ° of angles, promptly promotes groove 11 and ball mill direction of rotation and is 60 ° of angles.When ball mill rotated, the steel ball in the ball mill barrel 1 snapped in and promotes in the groove 11, rotates thereupon, and when turning to ball mill barrel 1 top, steel ball grinds material through the friction between the steel ball because the gravity effect is fallen.

The outer wall place of liner plate 13 is provided with sound absorption groove 14, and this sound absorption groove 14 and the 11 alternate settings of lifting groove when liner plate 13 is installed, are inserted sound-absorbing material layer 15 in the sound absorption groove 14 of liner plate 13, and this sound-absorbing material layer 15 can be materials such as foamed plastics.Be lined with sound-absorbing material lining 12 between liner plate 13 and ball mill barrel 1 inwall, this sound-absorbing material lining 12 can be processed by composite rubber material etc., passes through bolt then.Can effectively absorb and consume the vibrational energy of liner plate 13 and ball mill barrel 1 through sound-absorbing material layer 15 and sound-absorbing material lining 12, thereby reduce the noise of ball mill.
