Description
Technical field
The present invention relates to a kind of building materials crushing material equipment, be specifically related to a kind of material ball mill device.
Background technology
After ball mill is material fragmentation, carry out the key equipment pulverized again, the production industry such as extensive use and non-ferrous metal ore, the steel ball of inside promotes by centrifugal force when existing ball mill general rotates, and is pulverized material by the interaction between steel ball and material.Spheroid is generally made by metal or nonmetallic materials, rotate with ball mill barrel, abrasive body turns round again and again in cylindrical shell, leave, roll, the motions such as slip, by impacting between abrasive body and material, rubbing action forms transferring energy, by smashing, grind mode comminuting matter, and existing abrasive body is due to smooth surface, in impact, in friction process, overwhelming majority energy is not utilized, and change heat energy, acoustical energy losses is fallen, the effective rate of utilization of energy is very low, be only 1 ~ 3%, ball mill power consumption is high, ball mill barrel is also fragile, have plenty of and add simple abrasion-proof backing block to extend the service life of machine barrel in machine barrel.No matter abrasion-proof backing block is perfectly smooth surface, still some decorative patterns are cast with from the teeth outwards, it is all rely on the stiction between liner plate and abrasive body to the castering action of abrasive body substantially, the confficient of static friction of ball mill by wet process is 0.35, the confficient of static friction of dry method ball mill is 0.4, because confficient of static friction is more much smaller than actual needs, so inevitably there is the phenomenon that abrasive body slides, liner plate hoisting depth is caused to reduce, the abrasion of liner plate and spheroid increase, reduce the grinding efficiency of ball mill, increase the wearing and tearing of liner plate.
In addition, in existing ball mill, bulky grain, middle particle, short grained material all mix, and ground by a kind of steel ball, not only spended time is long, and the effect of ball milling neither be fine.
Summary of the invention
For solving the problem, the invention discloses a kind of material ball mill device, not only ball milling is effective, Ball-milling Time is short, and extending the service life of liner plate.
A kind of material ball mill device, comprise cylindrical shell, described cylindrical shell two ends are provided with material inlet and material outlet, described inner barrel is provided with the first dividing plate and second partition, described first dividing plate and second partition are equipped with filter bores, filter bores aperture on described first dividing plate is greater than the filter bores aperture on second partition, cylindrical shell is divided into the first cylindrical shell by described first dividing plate and second partition, second cylindrical shell and the 3rd cylindrical shell, described first cylindrical shell, the inwall of the second cylindrical shell and the 3rd cylindrical shell is equipped with abrasion-proof backing block, the liner plate of described first cylindrical shell and the second cylindrical shell is equipped with projection, described first cylindrical shell, difform grinding steel ball is contained with respectively in second cylindrical shell and the 3rd cylindrical shell, steel ball body in described first cylindrical shell is cylindrical, upper end and the bottom of described cylindrical steel ball body are connected to circular arc-shaped end, steel ball surface in described second cylindrical shell has multiple projection.
As a further improvement on the present invention, the height that the projection on described first cylindrical shell and the second shell liner is protruded is 4cm.
As a further improvement on the present invention, the height of the steel ball surface projection in described second cylindrical shell is 4cm.
As a further improvement on the present invention, the cross sectional shape of the steel ball surface projection in described second cylindrical shell is trapezoidal.
Compared with prior art, tool of the present invention has the following advantages and beneficial effect: steel ball can be brought to peak by the projection on liner plate, adds the impulsive force that particle surface is subject to, and ball milled ingredients is faster, the time is short, and extends the service life of liner plate; The particle of different size is separated ball milling, ball milling better effects if.

Detailed description of the invention
Illustrate the present invention further below in conjunction with the drawings and specific embodiments, following detailed description of the invention should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in the figure, a kind of material ball mill device, comprise cylindrical shell 1, cylindrical shell 1 two ends are provided with material inlet 2 and material outlet 3, cylindrical shell 1 inside is provided with the first dividing plate 7 and second partition 8, first dividing plate 7 and second partition 8 are equipped with filter bores, on first dividing plate, the filter bores aperture of 7 is greater than the filter bores aperture on second partition 8, cylindrical shell is divided into the first cylindrical shell 4 by the first dividing plate 7 and second partition 8, second cylindrical shell 5 and the 3rd cylindrical shell 6, hold large respectively, in, little three kinds of particles, on first dividing plate, the filter bores of 7 can allow middle particle and small particles material pass through, large granular materials is stoped to pass through, filter bores on second partition 8 can allow small particles material pass through, granule materials in prevention.
The inwall of the first cylindrical shell 4, second cylindrical shell 5 and the 3rd cylindrical shell 6 is equipped with abrasion-proof backing block 9, and the height liner plate of the first cylindrical shell 4 and the second cylindrical shell 5 being equipped with the projection protrusion on protruding 10, first cylindrical shell and the second shell liner is 4cm.Be contained with abradant difform steel ball respectively in first cylindrical shell 4, second cylindrical shell 5 and the 3rd cylindrical shell 6, in the process of barrel body rotation, steel ball can be brought to peak whereabouts grinding material by projection.
Because the material in the first cylindrical shell 4 is bulky grain, so be cylindrical by the body design of the steel ball 11 in the first cylindrical shell, upper end and the bottom of cylindrical steel ball body are connected to circular arc-shaped end 111, which increases the contact area of steel ball surface and material, ball milling better effects if; Be middle granule materials in second cylindrical shell 5, only steel ball 12 surface in the second cylindrical shell 5 need be had multiple protruding 13 can realize good ball milling effect, and the cross sectional shape of this projection is preferably trapezoidal, and the height of the steel ball surface projection in the second cylindrical shell is 4cm; 3rd cylindrical shell 6 is small particles material, and the steel ball in the 3rd cylindrical shell 6 14 need use ganoid steel ball.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technical scheme be made up of above technical characteristic.
