Description
Technical field
It the utility model is related to a kind of ball mill technical field, in particular to the liner installed in ball mill barrel inwall.
Background technology
Ball mill is that one kind is widely used in ceramics, cement, silicate product, New Building Materials, refractory material, change
Grinding processing is carried out on the production industries such as fertilizer, non-ferrous metal ore and glass to various ores and other grindability materials to set
It is standby.Its cylinder of traditional ball mill is cylindrical shape, and cylindrical shape cylinder lumen is used to fill ballstone, grinding raw material and slurry etc.,
Its internal chamber wall is the cylindrical shape of rule, and liner is that surface is smooth, or has smaller equally distributed shape for lugs, and from ball mill
End face extend to other end.Ball mill drives its cylindrical shape barrel body rotation by motor, makes in cylinder lumen
Ballstone, which hits raw material, makes raw material crush and grind, and the levigate process of raw material is divided into two stages by ball mill, and the first stage is
Ballstone mutually hits when moving and drop with cylinder with raw material, raw material is carried out tentatively to crush, raw material size crushes from Centimeter Level
It is even more small for grade.First stage mainly tentatively crushes original by the mutual shock between the ballstone and raw material of large-size
Material.
Second stage will first stage tentatively broken raw material be ground into by ballstone extruding, the rubbing action of reduced size
Micron order size raw material, this stage are realized mainly by the ballstone of reduced size with more number or high-frequency grinding.
Because its cylindrical shape cylinder inboard wall of traditional ball mill is the cylindrical shape of rule, and its liner is surface light
It is sliding, or have smaller equally distributed projection, and other end is extended to from the end face of ball mill, it is in ball mill
Symmetrically and evenly it is distributed, raw material and ballstone be not by the active force of axial direction, and its process of lapping is mainly along cylinder inboard wall circumference
Direction is radially to carry out, substantially no large-scale axial impact and grinding, causes shock and the Rubbing number of ballstone and raw material
Less, ballstone motion blindness is larger, grinding efficiency is relatively low and the ball milling cycle is longer；And during ball mill rotation, by cylinder
Interior raw material, water and abrasive body (such as ballstone) drive arrive certain altitude together, and under gravity, the material in whole cylinder is in
Almost ball milling motor spindle is arrived in tenesmus to parabola simultaneously, caused larger eccentric moment, the jumping phenomenon of eccentric moment clearly,
When being turned up again, the increase of motor driving ball mill barrel operating power consumption, energy consumption are larger.
Utility model content
The technical problems to be solved in the utility model is to provide eccentric moment during a kind of reduction cylinder ball milling, improves ball milling
Efficiency, the cylinder lining for shortening the ball milling cycle, reducing energy consumption.
Technical scheme used by solve above-mentioned technical problem：A kind of ball mill barrel liner, includes and is fixed on cylinder
The liner of internal wall, some projections that interior lining is laid formed with rule, it is characterised in that：The projection is set as axially upper adjacent
Projection circumferentially stagger.
On the basis of the above, the projection is stepped in the axial direction or spiral distribution.
The height of the projection is more than or equal to the diameter of maximum abrasive body.
On the basis of the above, the liner is rubber lining or stone lining or medium/high aluminium lining.
Using beneficial effect caused by the utility model：Because the projection of liner is set as axially upper adjacent projection circumference
Stagger, that is to say not in the strip projection of word extension, such as stepped in the axial direction or spiral distribution, these projections
Sustained height can be continuously turned to the rotation of cylinder, the material of each axial direction part in such cylinder will be continuous
Fallen after constantly being thrown by the projection on corresponding axial direction part to certain altitude, it is in successive underground that the material of each axial direction part, which is also,
Fall, eccentric moment is held nearly constant, and can effectively reduce eccentric moment during cylinder operating.And the ball mill of convention liner,
The material of each axial direction part is to be tossed and fall simultaneously, and the whereabouts of material is intermittence, so for ball grinder motor,
A kind of intermittent powerful starting (material and ballstone are thrown the stage) and stress disappearance suddenly (material and ballstone can be formed
When under pendant) interim acting, the more power consumption of this mode of work-doing and the impact to transmission parts and damage are bigger.Using this practicality
New cylinder is advantageous to the acting of ball grinder motor small-power continuity, is also beneficial to transmission parts uniform stressed, extending it makes
Use the life-span.This mode of work-doing can become evenly continuous relative to the ball mill of convention liner, and each axial direction part region
Material and ballstone during tenesmus, other axial direction part regions material can be offset and thrown caused eccentric force after high point
Square, so as to improve the stress of ball mill, have the function that to save and protect reductor and motor, and extend mill's reducer,
The service life of motor and other transmission parts.Also, it can make on axial direction in the liner for the projection that is in staggered distribution in ball mill barrel
Material produces axial movement, the mutual collision frequency of increase material, strengthens grinding efficiency.When designing ball mill, motor, subtract
The transmission parts such as fast machine, power transmission shaft, so as to reduce the cost of ball mill, can play good economic benefit with selection of small model
Higher cost performance.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model cylinder.
Embodiment
As shown in figure 1, a kind of ball mill barrel liner, includes the liner 2 for being fixed on the inwall of cylinder 1, is formed on liner 2
There are some projections 3 that axial and circumferential interval is laid, in the utility model, the projection 3 is set as axially upper adjacent projection 3
Circumferentially stagger.These projections 3 strip that not convention liner extends in a word, these projections 3 meeting company with the rotation of cylinder 1
Continue and constantly turn to sustained height, the material of each axial direction part in such cylinder 1 will be continuously by corresponding axial direction part
On projection throw to certain altitude after fall, the material of each axial direction part is also in continuously falling, and eccentric moment is almost
Keep constant, can effectively reduce eccentric moment when cylinder 1 operates.Also, in the liner 2 for the projection 3 that is in staggered distribution, meeting on axial direction
Material in ball mill barrel 1 is produced axial movement, the mutual collision frequency of increase material, strengthen grinding efficiency.Specifically,
These projections 3 can be set as to axially upper stepped or spiral distribution.
Further, the height of the projection 3 is more than or equal to the diameter of maximum abrasive body.Larger-size projection is obvious
Projection 3 can take material and ballstone to higher height and drop again, there is bigger impulsive force, and phase after ball milling, material
When being ground into mud, the obvious liner 2 of projection is even more to play certain stirring action, accelerates the homogenizing and grinding effect of material
Rate, play energy-conservation and propose efficient effect.
And as the material of liner 2 conventional rubber lining or stone lining or medium/high aluminium can be used to serve as a contrast.
