Abstract
The utility model provides a ball mill tube body feed end thickening potassium steel welt, the right side limit while perpendicular to sail platband of welt and the right -hand member face of offal platband, the slope of left side limit sets up between the left end face of sail platband and offal platband, the infusion set's of welt left side and right side set up the locating hole, set up the hypotenuse on the terminal surface of sail platband and offal platband, the positive infusion set department of welt sets up the bellied round arc convex that makes progress, welt openly edge sets up the plane near sail platband and offal platband department, the circle arc convex both sides with set up the interior concave surface of transition circular arc between two planes, the top of the peaceful face of concave surface all increases 15mm's thickness component increase thickness layer in round arc convex, the circular arc that passes through, and the welt back sets up four piece at least concave districts of square, feed end shell liner life improves 50% with comparing originally to with middle -end, discharge gate welt life phase -match, wholly improve ball mill efficiency.
Description
Technical field
The utility model relates to ball mill barrel, especially a kind of ball mill barrel feed end thickening high manganese steel lining plate.
Background technology
The cylinder lining plate of ball mill that iron ore is used at present, design drawing is not considered large-size ball mill, and (for example Φ 4M*6M advises aboveLattice) feed end shell liner and middle part, discharge end working environment be different, and abrasion condition is also different, causes feed end service lifeAsynchronous service life with middle part, discharge end, feed end serious wear, has a strong impact on ball mill service efficiency.
In view of the foregoing, the structure of existing ball mill high manganese steel lining plate needs to improve.
Utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of ball mill barrel feed end thickening Gao Meng is providedSteel liner plate, feed end shell liner improved 50% service life compared with originally, and with middle-end, discharging opening liner plate service lifeMatch, entirety improves ball mill efficiency.
The utility model to achieve these goals, adopts following technical scheme: a kind of ball mill barrel feed end thickening potassium steelLiner plate is by liner plate, hypotenuse, locating hole, recessed district, arc convex surface, transition arc inner concave, plane, increase thick layerForm; The upper horizontal sides of liner plate is parallel each other with lower horizontal sides, and the right edge of liner plate is simultaneously perpendicular to upper horizontal sides and lower horizontal sidesRight side, limit, left side is inclined between horizontal sides and the left side of lower horizontal sides, the left side of the horizontal center line of liner plateWith right side, locating hole is set, on the end face of upper horizontal sides and lower horizontal sides, hypotenuse is set, described two hypotenuses taking horizontal center line asCentral Symmetry arranges, and horizontal center line place, liner plate front arranges the arc convex surface raising up, and liner plate front edge is near upper levelLimit and lower horizontal sides place arrange plane, between the both sides of described arc convex surface and described two planes, transition arc inner concave are set,Described two transition arc inner concaves are symmetrical arranged centered by horizontal center line, described arc convex surface, transition arc inner concave andThe thickness that the top of plane all increases 15mm forms increase thick layer, arc convex surface, the transition circle of described increase thick layer and liner plateArc inner concave and plane are integrally formed, the recessed district of at least four squares of bilateral symmetry setting of liner plate back side horizontal center line.
The beneficial effects of the utility model are: for the service condition of large-size ball mill, shell liner physical dimension is carried out againDesign, feed end shell liner improved 50% service life compared with originally, and with middle-end, discharging opening liner plate phase in service lifeCoupling, entirety improves ball mill efficiency. Former shell liner is regardless of feed end, discharge end, and physical dimension is all the same, now cylinderBody liner plate feed end size is changed, and feed end liner plate integral thickness increases 15MM, middle part, discharge end liner plate size constancy.Before improvement, in 5 months service life of feed end high manganese steel lining plate, after improvement, front end improved ball mill at 10 months service lifeIntegral production efficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is main TV structure schematic diagram;
Fig. 2 be in Fig. 1 A-A to cross-sectional view;
In Fig. 1,2: liner plate 1, hypotenuse 2, locating hole 3, recessed district 4, arc convex surface 5, transition arc inner concave 6, plane7, increase thick layer 8.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in the figure, the upper horizontal sides of liner plate 1 is parallel each other with lower horizontal sides, and the right edge of liner plate 1 is simultaneously perpendicular to upper levelThe right side of limit and lower horizontal sides, limit, left side is inclined between horizontal sides and the left side of lower horizontal sides, the water of liner plate 1The left side of flat center line and right side arrange locating hole 3, on the end face of upper horizontal sides and lower horizontal sides, hypotenuse 2 are set, described two tiltedlyLimit 2 is symmetrical arranged centered by horizontal center line, and liner plate 1 horizontal center line place, front arranges the arc convex surface 5 raising up,Liner plate 1 front edge arranges plane 7 near upper horizontal sides and lower horizontal sides place, the both sides of described arc convex surface 5 and described twoTransition arc inner concave 6 is set between plane 7, and described two transition arc inner concaves 6 symmetry centered by horizontal center line is establishedPut, the thickness that the top of described arc convex surface 5, transition arc inner concave 6 and plane 7 all increases 15mm forms increase thick layer8, described increase thick layer 8 is integrally formed with arc convex surface 5, transition arc inner concave 6 and the plane 7 of liner plate 1, liner plate 1The recessed district 4 of at least four squares of bilateral symmetry setting of back side horizontal center line.
