Abstract
The utility model discloses a wear-resistant ball grinding mill. The wear-resistant ball grinding mill comprises a ball grinding mill cylinder body and a transmission device, wherein the transmission device is connected with the ball grinding mill cylinder body; a lining plate is arranged in the ball grinding mill cylinder body; a sound absorption material lining layer is arranged between the outer wall of the lining plate and the inner wall of the ball grinding mill cylinder body; a lifting groove is formed in the inner wall of the lining plate; and wear-resistant layers are arranged on the inner wall of the ball grinding mill cylinder body and the inner wall of the lifting groove. According to the wear-resistant ball grinding mill, the abrasion performance of the ball grinding mill cylinder body can be improved, the wear rate is reduced, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to a kind of ball mill, relates in particular to a kind of wear-resisting ball mill.
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, pulverize by 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, simultaneously owing to enormous impact power and the frictional force of steel ball to ball mill barrel, produced serious noise pollution, the speed of steel ball is more big, and noise is more big.
In order to address the above problem, following patented technology has been proposed in the prior art:
China Patent No. " 201220000812.2 " discloses a kind of ball mill, and its open day is on 09 12nd, 2012.Its technical scheme is that described 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 described liner plate outer wall and the ball mill barrel inwall; The inwall place of described liner plate is provided with the lifting groove.But in actual use, because steel ball to enormous impact power and the frictional force of ball mill barrel, causes the spoilage height of liner plate, not only influence production efficiency, also make maintenance cost higher.
The utility model content
The purpose of this utility model is to solve the problems referred to above that ball mill exists in the prior art, and a kind of wear-resisting ball mill is provided, and the utility model can improve the wearability of ball mill barrel, thereby reduces its wear rate, is conducive to prolong service life of equipment.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of wear-resisting 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 described liner plate outer wall and the ball mill barrel inwall; The inwall place of described liner plate is provided with the lifting groove, it is characterized in that: be provided with wearing layer on the inwall of described ball mill barrel inwall and lifting groove.
Described wearing layer is the zinc coat that is coated on ball mill barrel inwall and the lifting groove inwall.
The thickness of described zinc coat is 5-15mm.
Adopt advantage of the present utility model to be:
One, in the utility model, owing on the inwall of described ball mill barrel inwall and lifting groove, all be provided with wearing layer, wearing layer can stop effectively that steel ball and material are to enormous impact power and the frictional force of ball mill barrel, thereby reduce steel ball and material to the spoilage of liner plate, reduced the time of maintenance ball mill, reduced maintenance cost, can enhance productivity effectively and prolong service life of equipment.
Two, in the utility model, described wearing layer is the zinc coat that is coated on ball mill barrel inwall and the lifting groove inwall, and this structure makes the anti-wear performance of liner plate better, the service life of further having improved liner plate.
Three, in the utility model, the thickness of described zinc coat is less than 5mm, and the anti-wear performance of liner plate is poor; And the thickness of zinc coat will cause production cost to rise less than 15mm; Therefore the thickness of zinc coat is set to 5-15mm, increasing under the prerequisite of cost seldom, good wear-resisting effect just can be arranged, and is simple and practical.
Description of drawings
Fig. 1 is the structural representation of ball mill barrel in the utility model.
Be labeled as among the figure: 1, ball mill barrel, 2, promote groove, 3, the sound-absorbing material lining, 4, liner plate, 5, wearing layer.
The specific embodiment
A kind of wear-resisting ball mill comprises ball mill barrel 1 and the transmission device that links to each other with ball mill barrel 1; Be provided with liner plate 4 in the ball mill barrel 1; Be provided with sound-absorbing material lining 3 between described liner plate 4 outer walls and ball mill barrel 1 inwall; The inwall place of described liner plate 4 is provided with and promotes groove 2, is provided with wearing layer 5 on the inwall of described ball mill barrel 1 inwall and lifting groove 2.
Preferred embodiment of the present utility model is, described wearing layer 5 is to be coated in ball mill barrel 1 inwall and to promote zinc coat on groove 2 inwalls, but is not limited to above-mentioned set-up mode, described wearing layer 5 also can for antifriction alloy just or micarex.
In the utility model, the thickness of described zinc coat can be 5mm, also can be 15mm, and the thickness of preferred described zinc coat is 10mm.
