Description
Technical field
The present invention relates to ball mill manufacturing technology field, relate in particular to a kind of combined lining board for ball mill.
Background technology
Ball mill be after material crushing with the key equipment in solid material refinement pulverizing process, its scope of application comprises cement, metallurgy, the generating, the pottery etc. industry.Ball mill realizes that the vital part in pulverizing process is liner plate, and liner plate has two effects: the one, and the protection cylindrical shell avoids abrasive body and material directly impacts and grinds; The 2nd, be used for adjusting the motion state of abrasive body and material in cylindrical shell.
In the cylindrical shell operation process, the surface of liner plate can be subject to the impact of abrasive body and material.The liner plate of conventional operation surface band screw is in manufacture process, and the surface can form stress and concentrate and micro-flaw, weakens the ability to bear of liner plate impact, and wearing and tearing are first from screw.This type of liner plate is fragile, and the life-span is short, has increased the ore grinding cost.
Chinese patent 201010500956.X " New type ball mill lining plate " discloses a kind of peak with liner plate and has been offset to the centre, increases the thickness in center bolt hole, so that liner plate easy fracture not is more wear-resisting.This way has been done restriction to the surface texture of liner plate, and different Lining board surface shapes is had different stressing conditions, causes the abrasive body motion state different with material in cylindrical shell, will bring very large trouble to design.And this structure can not be eliminated in the liner plate manufacture process, can occur near screw that stress is concentrated and the deficiency of micro-flaw.
Summary of the invention
The technical problem to be solved in the present invention is: in existing liner plate manufacture process with screw, the surface can form stress and concentrate and micro-flaw, weaken the deficiency of the ability to bear of liner plate impact, the invention provides a kind of combined lining board for ball mill, the working surface of this liner plate is complete curved surface, there is no opening, surface configuration can be selected according to operating mode.
the technical solution adopted for the present invention to solve the technical problems is: a kind of combined lining board for ball mill, comprise the lifting top part, described lifting top part bottom offers the inside groove for construction bolt, the bottom shape of described inside groove is more than or equal to the larger end of bolt, the notch of described inside groove is by opening, and the installing hole that is communicated with open end forms, the aperture of described opening more than or equal to the minor axis of the larger end of bolt to width, the aperture of described installing hole less than the minor axis of the larger end of bolt to width and more than or equal to the diameter of bolt body, can put bolt into from opening part, bolt can move to along inside groove the position of mounting hole at opening two ends.Described minor axis is the shortest width distance diametrically to larger end that width refers to described bolt, for example, when the larger end of bolt is square, radial width refers to the foursquare length of side, and during for circle, radial width refers to circular diameter, and during for rectangle, radial width refers to that the minor face of rectangle is long.The working surface of described lifting top part is complete curved surface, there is no the installation groove of common liner plate.
For two bolts can be installed, as preferably, described installing hole is comprised of the first installing hole that is communicated with the two ends of opening respectively and the second installing hole.
Also comprise adaptive base plate, described adaptive base plate is elastomeric material, and it coordinates with the bottom that promotes top part; Have be used to the circular hole that bolt body is passed through on described adaptive base plate, described circular hole is corresponding with the position of mounting hole on promoting top part.Adaptive base plate can not only play the effect of buffering, and can also be close to lifting top part and bolt, plays the effect of gluing, sealing.
For lifting top part and adaptive base plate are accurately located, the bottom of described lifting top part has locating hole, and the upper surface of described adaptive base plate has the cylinder boss that coordinates with locating hole.
In order to improve the antiwear property of liner plate, described lifting top part is the metal alloy compositions of high strength, high abrasion.
For adaptive base plate and bolt are closely cooperated, the Circularhole diameter of described adaptive base plate is less than the aperture of installing hole, and is substantially equal to the bolt body diameter.
Described adaptive base plate surrounding all has chimb, and described chimb surrounds the surrounding of described lifting top part.Some uses the wet grinding mill mineral ball mill, and liquid can be seeped under liner plate and be seeped into cylindrical shell, if surrounding has chimb, adaptive base plate relies on mutually with promoting top part, makes material not reach cylindrical shell, the protection barrel wall.
The thickness deltat h of described lifting top part bottom from its working surface to inside groove is 55mm～70mm.
Install and unloading for convenient, behind the larger end of described inside groove construction bolt, have gap d between the larger end of the surface of described inside groove and bolt, described gap d is 5～15mm.
The invention has the beneficial effects as follows, a kind of combined lining board for ball mill of the present invention, be skillfully constructed, make simply, promote top part and have complete working surface, the surface can not form stress and concentrate and micro-flaw in manufacture process, strengthen shock resistance, the antiwear property of liner plate, can improve the grinding efficiency of ball mill, extended liner plate service life, economical with materials reduces the ore grinding cost; Promote the adaptive base plate combination of top part and elasticity, can further improve combined lining board shock resistance, reduce noise, weight reduction to a certain extent simultaneously; When changing liner plate, adaptive base plate can be reused, and only needs to change the lifting top part; Adaptive base plate can play the effect of sealing, prevents the dust leakage, improves working environment; Good sealing effect, bolt can reuse.
