Description
Technical field
The utility model relates to the shell liner of ball mill, is meant a kind of ball mill barrel liner plate that the classification 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.
In the mechanical milling process, the major diameter abrading-ball mainly plays broken big particle diameter material, and the minor diameter abrading-ball mainly works to grind (fine grinding) small particle diameter material; The big particle diameter material of the first half of ball mill (feed inlet end) is more, and latter half (discharge port end) small particle diameter material is more.Therefore, the normal in the industry shell liner with " classification " function that adopts is called classifying lining board; Make the major diameter abrading-ball in the ball mill concentrated relatively to the feed inlet end of ball mill, the minor diameter abrading-ball is concentrated relatively to the discharge port end of ball mill.Like this, the first half of ball mill (feed inlet end) major diameter abrading-ball is more, and the efficient of broken rough material is just than higher; The latter half of ball mill (discharge port end) minor diameter abrading-ball is more, and the efficient of grinding the less mineral aggregate of particle diameter is also just than higher.Thereby, the output of raising ball mill.
Present classifying lining board, its charging aperture one side is thinner, discharging opening one side is thicker, and some classifying lining boards can be assembled into the annulus that an inner peripheral surface tilts to charging aperture direction B, and several such annulus are arranged along the ball mill axial direction and formed several inner periphery inclined-planes (seeing accompanying drawing 1); Abrading-ball is tumbled along this inner periphery inclined-plane after lower takes eminence to by classifying lining board, with the component that is subjected to towards charging aperture direction B, thereby abrading-ball is moved to the charging aperture direction; Higher because of major diameter abrading-ball center of gravity, promptly potential energy is bigger, so the major diameter abrading-ball is faster than the rolling speed of minor diameter abrading-ball, so major diameter abrading-ball more in the charging aperture direction set, and the minor diameter abrading-ball concentrates on apart from charging aperture position far away slightly; Thereby realize the relative classification of major diameter abrading-ball and minor diameter abrading-ball.The classification principle of this classifying lining board is by the frictional force of classifying lining board inner peripheral surface between abrading-ball major diameter abrading-ball and minor diameter abrading-ball to be with height, the abrading-ball that is in eminence is tumbled to the charging aperture direction along the inner periphery inclined-plane of shell liner, because of big than minor diameter abrading-ball of the rolling speed of major diameter abrading-ball, thereby realize the relative classification of major diameter abrading-ball and minor diameter abrading-ball.
The shortcoming of above-mentioned classifying lining board is, all abrading-balls are all in the charging aperture direction set, thereby, near the sphere of charging aperture is raise, the open ended mineral aggregate in this zone reduces thereupon, the efficient of broken mineral aggregate descends thereupon, and the major diameter abrading-ball concentrates the positive role major part that produces to be cancelled to feed inlet end relatively, and the effect that improves ball mill output is subjected to very big influence.
The utility model content
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple and reasonable, processing and manufacturing easily, can be effectively concentrate major diameter abrading-ball and increase mineral aggregate capacity relatively, significantly improve the ball mill barrel liner plate that the classification muscle is set of ball mill output at the ball mill feed inlet end.
The utility model is provided with the ball mill barrel liner plate of classification muscle, is to adopt following proposal to realize:
The ball mill barrel liner plate of classification muscle is set, and is that the prominent muscle of the bar shaped that is called the classification muscle is set on the base plate of shell liner, and prominent muscle of described bar shaped and shell liner are with ball mill barrel travel direction out of plumb.
In the utility model, prominent muscle of described bar shaped and shell liner are 95 °～120 ° with the angle α of ball mill barrel travel direction.
In the utility model, the height of described classification muscle is greater than the radius of minor diameter abrading-ball, less than the minor diameter ball radius.
In the utility model, the height of described classification muscle is less than the radius of major diameter abrading-ball.
Classification principle of the present utility model is: the utility model is installed on the ball mill barrel-type casing inwall, make the discharging opening direction of the angle opening of prominent muscle of bar shaped and ball mill barrel-type casing excircle tangential motion direction towards ball mill, when ball mill rotates, abrading-ball is taken to eminence by liner plate from lower, because the height of classification muscle is greater than the radius of minor diameter abrading-ball, less than the radius of major diameter abrading-ball, therefore, the major diameter abrading-ball can be crossed the classification muscle and not change the direction of motion substantially; The minor diameter abrading-ball then stoped straight line to fall by the classification muscle and along classification muscle inclined-plane to the landing of discharging opening direction, realized that thus the minor diameter abrading-ball is concentrated relatively to discharging opening.Because the minor diameter abrading-ball has been pulled to the latter half (discharge port end) of ball mill, so the abrading-ball quantity of ball mill latter half increases, the abrading-ball quantity of first half reduces, the sphere height of being piled into by abrading-ball is low early and high after shape, after the sphere height of latter half arrives to a certain degree, the major diameter abrading-ball and the minor diameter abrading-ball of latter half can roll to first half again under the effect of its partical gravity, the minor diameter abrading-ball is recycled to latter half again afterwards, the major diameter abrading-ball and the minor diameter abrading-ball of latter half can roll to first half again, so repeatedly, the major diameter abrading-ball of first half is further increased, and thus, the grading effect of abrading-ball is more remarkable.
The utility model is owing to adopt said structure, utilize described classification muscle a part of minor diameter abrading-ball to be pushed to the latter half of ball mill, make the sphere height of first half lower, first half has more space and holds mineral aggregate, can effectively improve the crushing efficiency to mineral aggregate.Because described classification muscle height is less than the diameter of minor diameter abrading-ball, make and filled up the minor diameter abrading-ball between classification muscle and the base plate basically, thereby, make most of major diameter abrading-balls cross the classification muscle and can not contact from the minor diameter abrading-ball with the classification muscle, avoid the classification muscle to produce, so the classification muscle have very long service life than heavy wear.
In sum, the utility model is simple and reasonable, processing and manufacturing is easy, classification muscle itself is not easy to wear, grading effect significantly, can effectively improve the crushing grinding efficient of ball mill.

The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
The utility model is provided with the ball mill barrel liner plate of classification muscle, is the prominent muscle 3 of bar shaped is set on the base plate 1 of shell liner, and prominent muscle 3 of described bar shaped and shell liner are with ball mill barrel travel direction A out of plumb; Prominent muscle 3 of described bar shaped and shell liner are 95 °～120 ° with the angle α of ball mill barrel travel direction A.
In the present embodiment, the height of described classification muscle 3 is 1.1～1.8 times of minor diameter abrading-ball radius, is 0.2～0.7 times of major diameter abrading-ball radius, and classification muscle and shell liner are 95 °～120 ° with the angle α of ball mill barrel travel direction.
The shell liner of present embodiment preparation, crushing grinding efficient is higher by 10%～30% than the conventional shell liner that classification muscle 3 is not set.
Classification process of the present utility model is sketched in following:
Greater than 90 °, angle α opening is towards the discharging opening direction of ball mill barrel with the angle α of ball mill barrel travel direction for classification muscle described in the utility model and shell liner, and the classification muscle tilts to discharging opening.When ball mill rotated, abrading-ball was taken to eminence by liner plate from lower, because the height of classification muscle is greater than the radius of minor diameter abrading-ball, radius less than the major diameter abrading-ball, therefore, the major diameter abrading-ball can be crossed the classification muscle and not change the direction of motion substantially, and vertical drop is to the material of ball mill bottom; The minor diameter abrading-ball is then stoped straight line to fall by the classification muscle and tumbles to the discharging opening direction along classification muscle inclined-plane, has realized that thus the minor diameter abrading-ball is concentrated relatively to discharge port end.After ball mill rotates certain hour, the abrading-ball of ball mill latter half increases, the abrading-ball of first half reduces, the sphere height of being piled into by abrading-ball is low early and high after shape, the sphere of latter half is high to be arrived to a certain degree, the steradian that tilts to charging aperture is increased to a certain degree thereupon, and the abrading-ball on the sphere of inclination produces bigger partical gravity, and the major diameter abrading-ball and the minor diameter abrading-ball of latter half can roll to first half again; Because the center of gravity of major diameter abrading-ball is higher, promptly potential energy is bigger, so rolling speed makes the major diameter abrading-ball further concentrated relatively to feed inlet end greater than the minor diameter abrading-ball.The minor diameter abrading-ball is recycled to latter half again afterwards, the major diameter abrading-ball and the minor diameter abrading-ball of latter half can roll to first half again, and so repeatedly, major diameter abrading-ball major part focuses on the first half of ball mill, thus, the remarkable grading effect of abrading-ball is achieved.And low early and high after sphere height makes the first half of ball mill hold more mineral aggregate, has improved the crushing efficiency to mineral aggregate, has overcome the shortcoming of existing liner plate.
