Abstract
The utility model discloses a composite ceramic lining board for large scale ball grinder, comprising a liner and a lining board frame. The liner is wave shape; a plurality of mounting holes are arranged on the liner; the bottom of the mounting hole is fastened with a special type heat-resistance rubber gasket; a fine ceramics is fastened and arranged on the rubber gasket in the mounting hole; the upper part of the fine ceramics forms the arc convex on the inner surface of the liner. The lining board frame comprises a frame face and a stabiliser; the lining board frame face adheres to the underside of the lining board; the lining board frame face is wave shape. The wear resistance of the utility model is good; the using time is three overhaul periods. The weight is light; the structure of the ball grinder is more compact; the energy consumption is saved. The installation, disassembly and the maintenance are convenient. The hardness is high, being good for increasing the grinding efficiency. The generated noise is reduced; the noise part is attenuation; the noise harm is reduced. The service life is extended; the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of large-size ball mill liner plate.
Background technology
In modern electric power, cement, mine, control in the industry such as gold, chemical industry, flouring technology occupies extremely important status, the key equipment of attrition process is pulverized in conduct in the flouring technology, large-size ball mill is by general employing, bringing into play enormous function in numerous industrial circles, the ball mill total amount of the whole nation more than 50 tons is above 40,000 according to statistics.Along with development of productivity, angle from efficient and low consumption, the power and the barrel diameter of ball mill constantly increase, impulsive force is big, the temperature height, the harsh ball grinding machine lining board of body of work part that causes of its service condition lost efficacy at short notice, not only wasted great amount of manpower and material resources, and had reduced the effective rate of utilization of equipment.
In recent years, abrasion-resistant stees such as high-chromium white cast iron, potassium steel obtain using more and more widely in the ball mill industry, and the annual only steel of a consumption of liner plate just reach several hundreds of thousands tons.Along with rich chromium cast iron and other high-quality abrading-ball are applied, the wearing and tearing of liner plate will be more serious.Large-size ball mill is because diameter of cylinder is big, and the impact of abrading-ball is very violent, and wear liner is especially serious.
Generally adopt abrasion-proof cast steel lining board in the large-size ball mill at present, mainly have following problem:
One, liner plate hardness is lower, and wearability is relatively poor, and wear life can only reach an overhaul phase substantially, thereby must increase thickness to guarantee wear life.With the abrasion-proof manganese steel liner plate is example, and every average thickness reaches 10 centimeters, and weight reaches 75 kilograms.This not only makes the ball mill structure too fat to move, has more strengthened power consumption.
When two, ball mill moves, because the steel ball bump produces huge noise.The performance of cast steel liner plate absorption and insulating noise is all relatively poor, makes the on-the-spot noise hazard of equipment operation very serious.
Three, cast steel liner plate is very heavy, and it is all pretty troublesome both to have safeguarded for installation, dismounting, wastes time and energy.
Summary of the invention
The purpose of this utility model aims to provide a kind of hardness height, and wearability is good, wear life is long, can alleviate own wt, reduces noise, saves power, saves the large-size ball mill ceramic composite lining board of cost.
The purpose of this utility model realizes by following manner:
The utility model comprises liner plate, liner plate frame, the liner plate undulate, liner plate is provided with several installing holes, the installing hole bottom is arranged with extraordinary heat-resistant rubber gasket, fine ceramics is installed on the interior rubber sheet gasket of installing hole, and fine ceramics top is formed with arc convex surface at the liner plate inner surface, and the liner plate frame comprises frame face and leg, liner plate frame face be close to be fixedly connected on liner plate below, liner plate frame face cooperates also undulate with liner plate.
Described installing hole is a through hole, is up-small and down-big cone shape, and extraordinary heat-resistant rubber gasket is fastened on the installing hole bottom, above the liner plate frame.
Described fine ceramics is ball tip circle cone-shaped.
It is fixing to guarantee that like this pottery can clamp well, guarantees the duty that pottery is stable.
The utility model is to assemble the waveform ceramic composite lining board that fine ceramics and extraordinary heat resistant rubber and liner plate frame combine by the porous steel part.
This kind structure of the present utility model has very high hardness, intensity and fracture toughness, thereby has possessed incomparable wearability and the impact resistance of cast steel liner plate.The arc convex surface of a plurality of potteries in the liner plate has strengthened ceramic fracture toughness and impact strength.Add that rubber sheet gasket can bear the operating high temperature of ball milling face, form ironclad, special wear-resisting ceramic scuff-resistant coating like this, and play the effect of buffering, damping and absorption noise.The science of liner plate frame designs, and has both strengthened the intensity of liner plate, has alleviated the weight of liner plate again significantly, has reduced the load of equipment effectively, reaches to reduce the convenient purpose of installing of energy resource consumption.
Thereby the utlity model has following advantage
One, the utility model wearability is good, reaches three overhaul phases service time.
Two, weight reduction.Average every block of liner plate deadweight can alleviate 1/3rd, not only makes the ball mill more compact structure, and energy efficient.Its installation, dismounting had both been safeguarded easily.
Three, ceramic lining plate hardness height helps improving grinding efficiency.
Four, the padded coaming rubber sheet gasket can reduce the generation of noise, and noise is partly decayed, and reduces noise nuisance.
Five, increase the service life, reduce maintenance cost.Conservative estimation relative manganese service time of the present utility model prolongs more than the twice.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model comprises liner plate 1, liner plate frame 2, and liner plate 1 undulate, liner plate 1 are provided with several installing holes 3, and described installing hole 3 is a through hole, is up-small and down-big cone shape, and extraordinary heat-resistant rubber gasket 4 is fastened on installing hole 3 bottoms, above the liner plate frame 2.
Fine ceramics 5 is installed on the rubber sheet gasket 4 in the installing hole 3, and fine ceramics 5 tops are formed with arc convex surface at liner plate 1 inner surface.Thereby form the ceramic scuff-resistant coating of a plurality of ceramic arc convex surface of tool at liner plate 1 inner surface, improve the abrasionproof performance of equipment.Liner plate frame 2 comprises frame face 6 and leg 7, liner plate frame face 6 be close to be fixedly connected on liner plate 1 below, liner plate frame face 6 cooperates also undulate with liner plate.
Described fine ceramics 5 is ball tip circle cone-shaped.
