Description
Technical field
The utility model relates to a kind of shoe, is specifically related to a kind of ball mill combined type liner plate.
Background technology
Ball mill is a kind of milling equipment that is widely used in electric power, pottery, cement, mineral manufacture field.Its basic functional principle is: ball mill barrel rotates with certain rotating speed, and the abrading-ball of ball mill barrel bottom receives centrifugal force, function of friction, and it is attached on the shell liner.After abrading-ball is brought to certain altitude, thrown down owing to the gravity of self, the abrasive material bottom the cylindrical shell is carried out impact comminution and grinding.Liner plate is the crucial abrasionproof parts of ball mill, and abrading-ball causes the wear liner attenuate to the severe impact effect meeting of ball grinding machine lining board.
Mainly there is following deficiency in existing ball mill barrel liner plate:
1, dribbling is limited in one's ability.Being provided with of liner plate crest mainly is in order to improve its dribbling ability, to have liner plate now for reducing the crest rate of depreciation, crest is arranged to low-angle, having limited its dribbling ability;
2, grading effect is poor.Material in ball mill to be distributed as the feed end bulky grain many, the discharge end granule is many.Most of liner plate does not possess grading function; Abrading-ball is evenly distributed in the ball mill; Even reverse classification appears, inconsistent with the pulverizing rule of ball mill " big pellet impact large granular materials, bead grind small particles material ", thereby crush efficiency and disposal ability are all on the low side; Liner plate with grading function, there is irrationality in its structure, thereby grading effect is poor, and is fast because of the rate of wear simultaneously, and ball mill is after operation a period of time, and the liner plate grading effect weakens even disappears;
3, crest serious wear.When abrading-ball and liner plate took place to slide relatively, crest received the friction of abrading-ball particularly serious, thereby crest attenuate rapid speed, the dribbling ability drop;
The utility model content
The purpose of the utility model is to overcome above shortcoming, provide a kind of and can improve the dribbling ability, and grading effect is good, the ball mill combined type liner plate that anti-wear performance is good.
The technical scheme of the utility model is:
A kind of ball mill combined type liner plate; Comprise that at least two kinds of working face shape liner plates inequality rearrange; The non-dribbling end of said liner plate and dribbling end are respectively arranged with boss; Said boss is formed S shape structure by concave curved surface and convex surface, and the radius of curvature of said dribbling end boss concave curved surface is provided with crest greater than the radius of curvature of said non-dribbling end boss concave curved surface between the dribbling end boss of at least a said liner plate and the non-dribbling end boss; The arc radius that said crest is met sphere is 10-25mm; Said crest is 40-80mm along the arc radius of sphere, said crest meet sphere and along the line of sphere and liner plate working face respectively with the ball mill barrel parallel axes or intersect, meet sphere and suitable sphere and the line of liner plate working face and the said crest of ball mill barrel axes intersect and favour the ball mill discharge end.
