Description
Technical field
The utility model belongs to mine equipment equipment technical field, and in particular to a kind of semi-autogenous mill liner plate.
Background technique
Semi-autogenous mill is the equipment that part using ore itself, partially carries out ore grinding as milling medium using steel ball, from
The viewpoint of energy effective utilization, using semi-autogenous mill ore grinding, energy consumption is relatively high.But semi-autogenous mill work fine crushing instead of in
Industry, screening operation, ore transhipment are alleviated, and shorten process, reduce the generation of dust, effect on environment is small.Meanwhile ore
Grinding is degraded mainly by ore itself, and steel ball consumption is low, small thus more next to the chemistry or Electrochemical forces of subsequent flotation operation
More it is concerned by people.
In the process of lapping for carrying out ore, need to reduce using the barrel and end cap of lining plate structure protection semi-autogenous mill
The impact that barrel and end cap are subject to, semi-autogenous mill liner plate is easy to happen abrasion when in use at present, as semi-autogenous mill size is got over
To come bigger, movement velocity of the ore in grinding machine is also increasing, and the both ends additionally, due to existing liner plate are plate armature,
So that the impact and abrasion that liner plate is subject to are also increasingly severe, constantly occur being broken and causing grinding machine maintenance down, operating rate
Low situation occurs, and constrains the service performance of semi-autogenous mill, makes troubles to production.
Summary of the invention
In order to solve the above-mentioned technical problem the utility model, provides a kind of semi-autogenous mill liner plate, structure is simple, designs
Rationally, backgauge protrusion is added in the two sides of liner plate, under the premise of not influencing ore grinding efficiency, reduced in mill running mistake
The speed of related movement of abrading-ball and material and the liner plate in grinding machine in journey significantly reduces liner plate concentrated wear problem, extends
The service life of liner plate reduces detachable maintaining liner plate the time it takes.
The technical scheme adopted by the utility model is a kind of semi-autogenous mill liner plate, including bottom plate, intermediate projections and gear
Material protrusion, base plate plane is sector structure, and the upper surface middle position of bottom plate is provided with the intermediate projections with bottom plate integrally connected,
The junction of intermediate projections and bottom plate is provided with the transition arc one to increase intermediate projections intensity, the two side ends position of bottom plate
Install and be equipped with identical with the protrusion direction of intermediate projections backgauge protrusion, backgauge protrusion and bottom plate integrally connected, backgauge protrusion with
The junction of bottom plate is provided with the transition arc two to increase backgauge protrusion intensity.
The mounting hole through intermediate projections and bottom plate is offered in the intermediate projections, mounting hole section is elongate holes,
The liner plate to be mounted on inside semi-autogenous mill, since liner plate quality is overweight, can be reached by mounting hole when being installed
The purpose finely tuned to liner plate.
The width of the intermediate projections is 2-5 times of backgauge ledge width, and the height of intermediate projections is backgauge height of projection
2-5 times, when being crushed to material, the main pulverization that material is realized using intermediate projections, since intermediate projections are set
The medium position in bottom plate is set, the bonding strength of intermediate projections and bottom plate can be increased, reduces the abrasion of intermediate projections.
When in use, the lower surface of liner plate bottom plate is bonded with grinding machine inner wall, bolt is penetrated in mounting hole, and screw thread connects
It connects on grinding machine, achievees the purpose that liner plate is fixed, when abrading-ball and material are moved in semi-autogenous mill, can use
Between protrusion and backgauge protrusion reduce the speed of related movement between abrading-ball and material and liner plate, due to being provided with gear at liner plate both ends
Material protrusion, can increase the intensity of liner plate itself, even if also can in the case where abrading-ball and material are constant to the impact force of liner plate
The abrasion resistance properties for enough increasing liner plate, extend the service life of liner plate.
The upper surface middle position of the bottom plate is provided with the intermediate projections with bottom plate integrally connected, intermediate projections and bottom plate
Junction be provided with the transition arc one to increase intermediate projections intensity；The purpose being arranged in this way is: in grinding machine work,
The main crushing realized using intermediate projections to ore, setting transition arc one can effectively increase intermediate projections and bottom plate it
Between bonding strength, reduce the probability of abrasion.
The both side ends position of the bottom plate is provided with backgauge protrusion identical with the protrusion direction of intermediate projections, and backgauge is convex
It rises and bottom plate integrally connected, the junction of backgauge protrusion and bottom plate is provided with the transition arc to increase backgauge protrusion intensity
Two；The purpose being arranged in this way is: after material and intermediate projections are hit, the material fragment crushed can be with backgauge
Protrusion collides, and setting backgauge protrusion is the intensity in order to increase liner plate end, advantageously reduces material and makes to liner plate end
At abrasion, to extend the service life of liner plate.
The utility model has the beneficial effects that
The utility model simple structure and reasonable design adds backgauge protrusion in the two sides of liner plate, is not influencing ore grinding
Under the premise of efficiency, the speed of related movement of abrading-ball and material and the liner plate in grinding machine is reduced during mill running, is had
Liner plate concentrated wear problem is reduced to effect, extends the service life of liner plate, reduces detachable maintaining liner plate the time it takes.
