Abstract
The invention discloses a central feeding device of a micron mill. The central feeding device of the micron mill is arranged on the outer circumference of a dual-partition chamber device between a front chamber and a rear chamber on a rotary cylinder of a micro-powder tube mill. The structure and the working principle of the central feeding device are shown in the abstract figure; a serial number 8 in the figure is a feed hopper of easily grinded material; the feed hopper is welded on a seal cover 9; the seal cover is fixed on a ground cement foundation 10; the material enters inside a rotary feeding body 11 from the feed hopper through the seal cover, and then passes through a plurality of equal involute feeding channels which are evenly distributed along the peripheral direction; the feeding channels pass through the wall of the rotary cylinder 2, so that the material enters inside the dual-partition chamber device 13, and enters inside the rear chamber to be milled after being gathered with the material from the front chamber. Thus, the device for playing a central feeding role of the micron mill is achieved.
Description
Technical field: described a kind of micron mill middle part feed arrangement is to be applied in industries such as China's building materials, mine, electric power, the harder objuct material is carried out a kind of device on the micron mill of fine grinding operation.Be that the broken machine of tube mill, ball mill, ball to prior art is in a technological innovation of feeding method.Raw material grinding, the calcination of cement clinker that micron mill middle part feed arrangement is widely used in the cement manufacturing add again multiple composite material together grinding become finished cement, in chemical industry lump material is carried out grinding operation, on the grinding operation that the power plant is levigate with lump coal.Described micron mill middle part feed arrangement is to have optimized the tube mill, the ball mill that use on the present market to have only an existing shortcoming of throat-fed, improves grinding machine to the mill efficiency of material.
Background technology: at present, in the old-fashioned tube mill that uses on the market, the rotating cylinder of ball mill, all be to be become by a storehouse or a plurality of storehouses row, separate with single compartment grate plate or two compartment grate plate between each storehouse.It feeds the mode of material the tube mill of prior art, ball mill, is to have only a material inlet of grinding mill barrel one end to give people's material, mainly has following two shortcomings; 1, varigrained material all enters in the mill from grinding previous charging aperture, the material thickness inequality behind the grinding, and yield rate is low.Meticulous powder can appear in the material that the grindability of little lumpiness is good, the material that is not easy grinding of bulk also do not reach the fineness requirement of standard, in order to guarantee qualified material, needs to reduce the feeding coal of grinding machine, cause mill hourly output low, grinding pow consumption such as increases at shortcoming.2, in order to solve the uneven problem of material thickness behind the grinding, prior art has also adopted a kind of closed-circuit grinding technology that increases external classification equipment at the afterbody of grinding machine, material behind the grinding machine grinding need enter an elevator, material is risen to after the certain height, carry out the machinery separation that wind-force adds power in the reentrant powder concentrator, the more coarse grained material that powder concentrator is discharged is sent to the front end charging aperture of tube mill through conveying equipment, carries out the repetition grinding operation.The material that powder concentrator fine powder discharge gate is discharged is certified products, and this method equipment needed thereby is many, complex process, investment are big.Because the existence of above-mentioned two kinds of shortcomings, present technique invention are that a kind of micron mill middle part feed arrangement adopts this technology can improve mill hourly output afterwards, cuts down the consumption of energy.
Summary of the invention: Figure of description 1 has the micro mist tube mill of a kind of micron mill middle part feed arrangement, and its operation principle is; 1, anterior charging gear such as the sequence number 1 of existing current techique tube mill, the material that enter the hardness height here, be difficult for grinding, piece is big carries out grinding in sequence number 3 preceding storehouses; 2, at the micro mist tube mill of Fig. 1 sequence number 5 being installed is a kind of micron mill of the present invention middle part feed arrangement; Be the little material of lower, the easy grinding of hardness, piece that the feed hopper of easy grinding material feeds from the sequence number 8 on the feed arrangement of sequence number 5 grinding machines middle part, enter into sequence number 6 and be in two partition device for barn, the material that the material that two partition device for barn are come in the middle part feed arrangement and Qian Cang come together is sent in the storehouses, sequence number 4 back and carries out grinding.Grinding machine middle part feed arrangement can be set respectively at the front end in other grinding storehouses of back, enter the material that is more prone to grinding, the material of coming with preceding storehouse enters next storehouse in the lump and carries out grinding.Outside discharging mill, sequence number 7 grinding machine afterbody discharging openings finish the grinding process to material through finished product materials after the grinding in last storehouse.
A kind of micron mill middle part its structure of feed arrangement as shown in Figure 2, sequence number 8 is feed hoppers of easy grinding material, feed hopper is welded on the seal closure of sequence number 9, seal closure is fixed on the sequence number 10 ground cement bases by sequence number 16 supporting legs, the material of easy grinding passes seal closure from feed hopper and enters in the sequence number 11 revolution feed bodies, on the revolution feed body sequence number 12 circumferential ring geometric pattern feeding-passages are set, revolution feed body is along with sequence number 2 rotating cylinders together rotate, feeding-passage passes sequence number 2 rotating cylinders enters in two partition device for barn of sequence number 13 material, the grindability of coming in by the middle part feed arrangement is after material and the last storehouse material of coming here converges preferably, be that the batch turning centrum enters into next storehouse and carries out grinding by the sequence number 15 among Fig. 2 .1 again after kicking up by the lifting blade of sequence number 14, so far realize a kind of device of the effect of micron mill intermediate feed.When in order to adapt to various materials being carried out combined grinding, grindability and different-grain diameter that can be different according to different materials arrange a plurality of middle parts charging gear to the cylindrical shell of micron mill, to reach more rational grinding effect.
By the feed-type of above-mentioned a plurality of charging apertures, the material that make the hardness height, be difficult for grinding, piece is big enters into the preceding storehouse of grinding machine in advance, polished time lengthening in mill.And lower, the easy grinding of hardness, material that piece is little advance in the grinding mill barrel in next storehouse, and the polished time shortens in mill, make fine grain increase of material after by grinding that is not easy grinding, also make easy grinding material cross the minimizing of grinding phenomenon.Improved mill efficiency, mill hourly output increases, and power consumption descends.
Old-fashioned tube mill is used for the operation of grinding micro mist, use in market all think the power consumption height, yield poorly, the performance of enterprises is poor.After adopting the technology of micron mill of the present invention middle part charging gear, make fine grinding operation technology and equipment realize technological progress, reached than old-fashioned tube mill reduction work power consumption, mill tail discharging uniform particles, the fineness index is stable.Increase substantially unit-hour output.This new technology also can be applied in the technological transformation of the old-fashioned grinding machine in now just using, and makes old-fashioned grinding machine have the technique effect of micron mill middle part feed arrangement equally.
