Abstract
The invention discloses a ball mill barrel lining plate provided with a deceleration rib. A bottom plate of the barrel lining plate is provided with a strip protruding rib, and the strip protruding rib is vertical to the direction of the barrel lining plate along with the motion of a ball mill barrel; and the height of the strip protruding rib is greater than the radiuses of small-diameter milled balls and smaller than the diameters of the small-diameter milled balls and the radiuses of large-diameter milled balls. The strip protruding rib is used for preventing the relative motion of the small-diameter milled balls and the lining plate; when the lining plate and the milled balls have relative motion, the large-diameter milled balls can cross the strip protruding rib, a part of small-diameter milled balls are blocked by the strip protruding rib so that the large-diameter milled balls and the other small-diameter milled balls glance off the blocked small-diameter milled balls, the contact between the milled balls and the strip protruding rib and the bottom plate of the lining plate is avoided, the abrasion of the strip protruding rib and the bottom plate is greatly relieved and the service life of the lining plate is greatly prolonged. The lining plate has simple and reasonable structure, is easy to process and manufacture, and can effectively reduce the abrasion of the bottom plate of the ball mill barrel lining plate; the new strip protruding rib is not easily abraded, and the service life of the lining plate is greatly improved; and the lining plate can effectively save the material and reduce the halt overhauling time of a ball mill, and is suitable for industrialized production.
Description
Technical field
The present invention relates to the shell liner of ball mill, be meant a kind of ball mill barrel liner plate that the deceleration muscle is set especially; Belong to the crushing grinding field of mechanical technique.
Background technology
The shell liner of ball mill can be divided into crest part and bottom parts.The main effect of crest part is that abrading-ball is taken to certain height, so that abrading-ball is fallen the broken expeditiously or grinding mineral aggregate in suitable position; The main effect of bottom parts is the barrel-type casing of protection ball mill, and the barrel-type casing of ball mill is not contacted with mineral aggregate and abrading-ball, thereby not by mineral aggregate and abrading-ball wear down.
Existing ball mill barrel liner plate, the speed of related movement of bottom parts and abrading-ball approaches the velocity of rotation of ball mill.When ball mill turned round, bottom parts promptly contacted with abrading-ball with above-mentioned speed of related movement, and then abrading-ball slides on bottom parts, thereby also just bigger to the wearing and tearing of bottom parts, caused bottom parts prior to the crest partially spent sometimes.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art and provide a kind of simple and reasonable, processing and manufacturing easily, can effectively reduce ball mill barrel liner plate base plate deterioration, increase substantially the base plate ball mill barrel liner plate that the deceleration muscle is set in service life.
The ball mill barrel liner plate that the present invention is provided with the deceleration muscle is to adopt following proposal to realize:
The ball mill barrel liner plate of deceleration muscle is set, and is that the prominent muscle of the bar shaped that is called the deceleration muscle is set on the base plate of shell liner, and the prominent muscle of described bar shaped is vertical with the ball mill barrel travel direction with shell liner.
Among the present invention, the height of the prominent muscle of described bar shaped is greater than the radius of minor diameter abrading-ball, less than the diameter of minor diameter abrading-ball.
Among the present invention, the height of the prominent muscle of described bar shaped is less than the radius of major diameter abrading-ball.
Among the present invention, the height of the prominent muscle of described bar shaped equals the radius of minor diameter abrading-ball.
The present invention is owing to adopt said structure, utilize the prominent muscle of described bar shaped to stop minor diameter abrading-ball and liner plate to do relative motion, when liner plate and abrading-ball relative motion, the major diameter abrading-ball can be crossed the deceleration muscle, the minor diameter abrading-ball is blocked by the prominent muscle of bar shaped, and major diameter abrading-ball and minor diameter abrading-ball great majority can only nuzzle up from jammed minor diameter abrading-ball subsequently, be difficult to contact with the prominent muscle of the bar shaped that is lower than the minor diameter abrading-ball, liner plate base plate under the more difficult and jammed minor diameter abrading-ball contacts, so just formed abrasive manner with the ball milling ball, the wearing and tearing of the prominent muscle of the bar shaped on base plate and the base plate greatly alleviate, and increase substantially the service life of liner plate.
In sum; the present invention is simple and reasonable, processing and manufacturing is easy, can effectively reduce the deterioration of ball mill barrel liner plate base plate; and the prominent muscle of the bar shaped of newly establishing is not easy to wear yet; increase substantially the service life of liner plate; can effectively save material; reduce the maintenance downtime of ball mill, be suitable for suitability for industrialized production.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is the left view of accompanying drawing 1.
Among the figure: 1-base plate, 2-crest, the 3-bar shaped muscle of dashing forward, A-ball mill barrel travel direction.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the present invention is elaborated:
Embodiment 1
The ball mill barrel liner plate of deceleration muscle is set, and is that the prominent muscle 3 of bar shaped is set on the base plate 1 of shell liner, and the prominent muscle 3 of described bar shaped is vertical with the ball mill barrel travel direction with shell liner;
In the present embodiment, the height of the prominent muscle 3 of described bar shaped is 1.3 times of minor diameter abrading-ball radius, 0.4 times of major diameter abrading-ball radius.
In the present embodiment, the height of the prominent muscle 3 of described bar shaped is 1.5 times of minor diameter abrading-ball radius, 0.45 times of major diameter abrading-ball radius.
In the present embodiment, the height of the prominent muscle 3 of described bar shaped equals the radius of minor diameter abrading-ball, 0.3 times of major diameter abrading-ball radius.
Claims (3)
1. the ball mill barrel liner plate of deceleration muscle is set, it is characterized in that: the prominent muscle of bar shaped is set on the base plate of shell liner, and the prominent muscle of described bar shaped is vertical with the ball mill barrel travel direction with shell liner.
