Description
Technical field
The utility model relates to a kind of material disintegrating apparatus, mainly is a kind of ball mill in small, broken bits that the mill tail selects the powder function that has.
Background technology
Ball mill is a kind of equipment that is widely used in material grindings such as cement, slag, nonmetallic ore.Its small investment, properties of product are reliable and stable, but the energy effective utilization rate is low.The a lot of scholar's research in the world prove, the utilization of the grinding power of ball mill reality only is 3 percent to 8 percent of total energy consumption.Improving mill efficiency, saving energy and reduce the cost is current ball mill most important.
For energy-saving and cost-reducing, at present a lot of industrial and mining enterprises are with two table grinders series connection grinding, and grinding for one-level of front mainly plays fragmentation to material, the back be secondary grinding, mainly material is played abrasive action.Traditional one-level grinds material material fineness and relies on the discharging grate plate to control.Its drawback is out that the grind materials fineness is thicker, and a large amount of thick materials (more than the 2.0mm) draws off outside the mill and enters secondary grinding, thereby the grinding of secondary grinding is caused difficulty, and therefore causes the mill efficiency of whole grinding system to reduce.
Therefore, one-level ball mill internal structure is redesigned, development high efficiency, low power consumption, to go out the thin one-level ball mill of grind materials fineness very necessary.
The utility model content
Technical problem to be solved in the utility model provides a kind of ball mill in small, broken bits that the mill tail selects the powder function that has, it has increased the mill tail and has selected the powder structure, select the powder structure to rely on the rotational energy work of cylindrical shell, need not to increase extra power-equipment, and grinding efficiency is higher, the energy-conservation cost that reduces, simultaneously service life longer convenient disassembly, it is time saving and energy saving to install.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of have the mill tail and select the ball mill in small, broken bits of powder function, include frame, horizontally rotate on the frame grinding mill barrel is installed, the left and right side of grinding mill barrel is respectively equipped with feed arrangement and drawing mechanism, it is characterized in that: right-hand member is provided with the discharging grate plate in the described grinding mill barrel, and the discharging grate plate is provided with the seam of combing, and described discharging grate plate is divided into the inner chamber of grinding mill barrel the grinding storehouse and selects the powder storehouse, the annular inner wall in described grinding storehouse is provided with liner plate, is placed with a plurality of steel balls in the grinding storehouse; Be provided with two-way waste taper in the middle of described select in the powder storehouse, two-way waste taper is with the grinding storehouse and select the conducting of powder storehouse, the described choosing in the powder storehouse is provided with a plurality of arc screen frame (unit)s that radiation distributes that are around a circle, the arc screen frame (unit) is provided with the stainless steel sieve plate, the stainless steel sieve plate is provided with the wide sieve aperture of 0.8～1.2mm, the described central authorities of the inherent two-way waste taper in powder storehouse that select are provided with ventilating board, have the wide air vent of 2.0～2.5mm on the ventilating board.
Described discharging grate plate is made through precision cutting and heat treatment process of steel plate, and the discharging grate plate is provided with the wide comb seam of 4.0～5.0mm.
The compass screen surface curvature of described arc screen frame (unit) is Archimedes spiral.
The diameter of steel ball is 30～100mm in the described abrasive dust storehouse.
Selecting in the utility model to be provided with two-way waste taper in the powder storehouse, is for the effect by two-way waste taper, material that will be thicker (〉=1.0mm) return in the grinding storehouse and to continue grinding, and thinner material (≤1.0mm) draw off outside the mill.
The utility model has been transformed the discharge end of traditional ball mill, it has been increased in the mill select the powder function.During work, material enters through the comb of discharging grate plate seam and selects the powder storehouse, selects powder selection devices such as stainless steel sieve plate in the powder storehouse and two-way waste taper, and they rotate with grinding mill barrel.By the effect of powder selection device, thinner material (less than 1.0mm) draws off outside the mill, and thicker material is greater than 1.0mm) return and continue grinding in the grinding storehouse.Grind the ventilating board that tail also is provided with Kong Kuanwei 2.0～2.5mm simultaneously, can avoid wind-force that thicker material is taken out of outside the mill.
The utility model has the advantages that:
The utility model is transformed the discharge end of traditional ball mill, has increased mill tail powder selection device, and powder selection device relies on the rotational energy work of cylindrical shell, need not to increase extra power-equipment, and is not only energy-conservation, and reduced investment.Because powder selection device rotates with cylindrical shell, select the rotating speed of powder frequency and cylindrical shell suitable, so select powder frequency height, and select at every turn powder can both with most of qualified thin materials (≤1.0mm) draw off outside the mill, therefore, grinding efficiency is higher.Simultaneously powder selection device is provided with sieve plate, and its sieve aperture is less, and (wide by 0.8～1.2mm), the material that draws off the one-level mill like this after the sorting is (less than 1.0mm, and 95% less than 0.5mm) carefully.
The utility model is easy to maintenance, and the powder selection device consumable accessory is discharging grate plate, stainless steel sieve plate and ventilating board, and grow (2～3 years) their service life, cheap, convenient disassembly, and it is time saving and energy saving to install.
