Abstract
The utility model relates to an efficient internal powder selecting device of a ball mill. At least one internal powder selecting device is arranged in the cylinder body of the ball mill, and comprises a double-layered hollow bracket, a screen plate, a grid plate and a blind plate, wherein the screen plate and the grid plate are mounted on the double-layered hollow bracket in the feeding direction; the blind plate is mounted on the double-layered hollow bracket in the discharging direction; a grading cone is mounted in the central position of the double-layered hollow bracket; a plurality of material raising plates are arranged between the screen plate and the grid plate; and a plurality of material raising holes are formed on the material raising plates. The material raising plates with the material raising holes are used for screening ball-milled coarse powder and fine powder in all bins to enable coarse powder to be led into a front bin from the grading cone and fine powder to be led into a rear bin from the grading cone, so that the machine-hour output is improved considerably, high effect, high yield and low energy consumption in powder selecting are ensured effectively, and the efficient internal powder selecting device is suitable for processing powder in fields of ground cement, slag, pulverized fuel ash and the like.
Description
Technical field
The utility model belongs to manufacture of cement grinding process system, relates to a kind of cutting down the consumption of energy, and improves output, increasing specific surface area, powder selection device in dynamical ball mill is efficient.
Background technology
The ball mill of manufacture of cement industry popularization at present all is the lengthening mill, is suitable for open circuit and grinds.In order to guarantee qualified fineness, some producer uses powder concentrator, though and powder concentrator be installed guaranteed product quality, the also corresponding output that improved; But equipment has high input, complex process, and operating cost is high; The fan blade of powder concentrator is easy to wear, fineness often takes place change, and influences product quality.
Selecting powder in the present new and effective mill is in mill is installed in the partition panel position, to select the powder double-layered isolating plate; One storehouse is sieved through the material that the comb plate imports, and screening is to rotate to promote with grinding machine through lifting blade to kick up, and the material of kicking up is because grinding machine rotation in opposite directions; Material can not scatter; Meal mixes with fine powder, and the part fine powder has reduced efficient along with meal is got back to last storehouse again.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, can effectively sieve meal and fine powder, and grinding efficiency is high, powder selection device in energy-saving and cost-reducing ball mill is efficient.
In order to achieve the above object; The technical scheme that the utility model adopts is: powder selection device in a kind of ball mill is efficient; Powder selection device in being provided with at least one group in the ball mill barrel; Interior powder selection device comprises double-deck hollow stent, is installed in sieve plate and the comb plate on the double-deck hollow stent feedstock direction and is installed in the blind plate on the double-deck hollow stent discharging direction; Classfied cone is installed in the center of double-deck hollow stent, is provided with a plurality of lifting blades between sieve plate and the comb plate, and it is characterized in that: said lifting blade is provided with some lifting holes.
Evenly setting and some lifting holes account for lifting blade surface area at least 60% at interval in some lifting holes.
In every group in the powder selection device lifting hole of lifting blade greater than the sieve aperture of sieve plate.
The sieve aperture of sieve plate is progressively diminished to the discharging direction by feedstock direction in the interior powder selection device of many groups.
The comb plate of interior powder selection device and blind plate are by being bolted on the double-deck hollow stent, and sieve plate and lifting blade are welded on the support between double-deck hollow stent and comb plate, and double-deck hollow stent is by being bolted to the ball mill barrel inwall.
Be separated at least two working bins by powder selection device at least one group in the cylindrical shell of ball mill; Requirement according to process conditions; Powder selection device in being provided with two groups in the cylindrical shell of general long ball mill; Cylindrical shell is divided into cracking cabin, crushing grinding storehouse and grinds the storehouse, by the abrasive body of filling different size in each bin of material processing technology requirements, material along the cylindrical shell feedstock direction to the three level work storehouses fragmentation of discharging direction warp, grind to form qualified powder.
After ball mill starts rotation; Large granular materials gets into the ball mill cracking cabin; The big steel ball abrasive body of different size impacts, grinding is broken into small particles material with large granular materials, and small particles material gets into the comb plate, and lifting blade plays the dual-use function of lifting and sieve powder; Material is got back to cracking cabin along with the wind speed granule of mill inner ventilation gets into the crushing grinding storehouse through sieve plate greater than the particle of sieve aperture; The small particles material that gets into next storehouse becomes fine powder through the crushing grinding of the small ball abrasive body of various different sizes; Fine powder is through secondary screen powder device; The sieve plate of the requirement sieve powder device that material changes and all corresponding the dwindling in hole of lifting blade; The fine powder that screens gets into three storehouses, and underproof fine powder is got back to two storehouses, and the fine powder that gets into three storehouses grinds to form needed qualified powder through the forging abrasive body of various different sizes.
The lifting blade in the utility model utilization band lifting hole sieves meal and the fine powder behind the bin ball millings at different levels; Make meal import last bin, fine powder importing back one bin by classfied cone; Thereby increase substantially unit-hour output; Effectively guarantee to select high-effect, the high yield and the low energy consumption of powder, be fit to the powder processing in fields such as mill cement, slag, flyash.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: cylindrical shell 1, double-deck hollow stent 2, comb plate 3, blind plate 4, sieve plate 5, lifting blade 6, classfied cone 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among Fig. 1: powder selection device comprised cylindrical shell 1 and at least one group of interior powder selection device in a kind of ball mill was efficient; Interior powder selection device comprises double-deck hollow stent 2, is installed in sieve plate 5 and the comb plate 3 on the double-deck hollow stent feedstock direction and is installed in the blind plate 4 on the double-deck hollow stent discharging direction; Classfied cone 7 is installed in the center of double-deck hollow stent 2; Be provided with a plurality of lifting blades 6 between sieve plate 5 and the comb plate 3; Lifting blade 6 is provided with some lifting holes, and evenly setting and some lifting holes account for lifting blade 6 surface areas at least 60% at interval in some lifting holes; The lifting hole of lifting blade is greater than the sieve aperture of sieve plate in the powder selection device in every group, and the sieve aperture of sieve plate is progressively diminished to the discharging direction by feedstock direction in the interior powder selection device of many groups.
