Abstract
The utility model provides an inner screen bar crushing and milling device comprising a support, a screw materials feeding barrel which is provided on the support and which includes a feed drum, a mill warehouse connected with the screw materials feeding barrel and a materials outlet screw barrel connected with the mill warehouse. The utility model is characterized in that screening liner plates equipped with grate holes are provided inside the barrel body of the mill warehouse. A screw passage communicated with the materials outlet of the mill warehouse is arranged between the screening liner plates and the barrel body. The utility model has the advantages of high working efficiency, high volume of production, low power consumption and capability of controlling the discharging granularity. The utility model can be widely used in industries such as construction material, chemical industry, mineral extraction and the like.
Description
The utility model relates to a kind of broken grinding machine, particularly be a kind ofly be specially adapted to contribute, the interior sieve rod mill of industry such as chemical industry and mining.
Existing ball mill comprises supporting, contains the spiral feeding cylinder of feed drum, mill storehouse, discharging spiral tube.The mill storehouse is made up of cylindrical shell and the flat liner plate that is loaded on the cylindrical shell.Mill is equipped with steel ball (rod) in the storehouse.The material of waiting to mince enters Mo Cang from feed drum through the spiral feeding cylinder, the rotation of mill storehouse, and the steel ball (rod) in it breaks up material and discharges from discharging spiral tube with the material collision.This kind ball mill inefficiency only has 2～3%, yields poorly, and energy consumption height, discharging-material size are difficult to be controlled in the limited range, crushing phenomenon often occurs.
In view of above reason, the purpose of this utility model is for a kind of high efficiency is provided, the output height, and energy consumption is low, the controlled interior sieve rod mill of making material granularity.
The purpose of this utility model is achieved like this:
The sieve rod mill comprises supporting in the utility model, place the spiral feeding cylinder that contains feed drum in the supporting, the mill storehouse that is connected with the spiral feeding cylinder, the discharging spiral tube that is connected with the mill storehouse, in the mill storehouse cylindrical shell liner plate that sieves that contains the castor hole is housed, is equipped with between sieve liner plate and cylindrical shell and grinds the helical duct that the warehouse discharging mouth communicates.
Above-mentioned mill storehouse barrel front end diameter is less than the rear end diameter, mill storehouse barrel front end have is connected with cylindrical shell in liner plate, the liner plate that sieves, spiral way are positioned at mill storehouse cylinder back-end, it is even to hit material.
There is the lifting screening plant that communicates with helical duct and mill warehouse discharging mouth at above-mentioned mill warehouse discharging mouth place.
Above-mentioned lifting screening plant comprises that placing mill warehouse discharging mouth place to contain imitates a feed back passage 18 that communicates with mill warehouse discharging mouth, discharging spiral tube respectively and the center burden-guiding cone of exit passageway 19, have respectively in several lifting sieves to be loaded on the lifting body that the exit passageway 19 with on the burden-guiding cone of center on the burden-guiding cone of center communicates, be loaded on the lifting blade that contain sieve aperture relative on the lifting body with helical duct.
Castor hole on the above-mentioned liner plate that sieves is bar shaped castor seam.
Castor hole on the above-mentioned liner plate that sieves is a circular port, also can be other shape.
Referring to Fig. 1～Fig. 4, during the utility model work, material is through feed drum, the spiral feeding cylinder is forced to send in the mill storehouse, hammering at steel ball (rod), pulverized under the resultant force effects such as extruding and shearing, when reaching, pulverized raw meal particle size preestablishes particle diameter when following, spill by the castor hole in the liner plate that sieves, enter the lifting screening plant via the passage that is spirally connected, thereby avoided common grinding machine that the defective of crushing phenomenon was arranged fully, improved crush efficiency, after entering the lifting screening plant, pulverized material is carried out screening once more, diameter of particle satisfies the previously selected certified products of user and enters the spiral discharging tube by center burden-guiding cone exit passageway, and defective part is then returned in the mill storehouse by the feed back passage and pulverized.To draw off overall process all be by the spiral forced conveyance to material by being fed to, to guarantee to have enough output.
The utility model did not have crushing phenomenon, and its discharging-material size can be strict controlled in the limited range.Operating efficiency significantly improves, and can reach 20%～30%, the output height, and energy consumption is low, can pulverize all kinds of ores, and clinkers etc. are specially adapted to contribute, the precomminution of industry such as chemical industry and mining.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model schematic appearance.
Fig. 2 is the utility model structural representation.
Fig. 3 is a lifting screening plant structural representation.
Fig. 4 is a lifting body structure schematic diagram.
Referring to Fig. 1～Fig. 4, in supporting 1,2, sliding bearing 3, rolling bearing 4 are arranged respectively.The front end that is contained in the spiral feeding cylinder 5 in the rolling bearing 4 has feed drum 6.The point diameter of the cylindrical shell 8 in the mill storehouse 7 is less than the rear end diameter.Cylindrical shell 8 front ends are equipped with flat liner plate 9, and sieve plate end liner 10 is equipped with in the rear end.The liner plate 11 that sieves that polylith contains bar shaped castor seam is housed on sieve plate end liner 10 peripheries.At the sieve plate end liner, sieving has helical duct 12 between liner plate and cylindrical shell.Lifting screening plant 15 is contained in barrel discharge hole 13 places.Have on its center burden-guiding cone 16 several respectively with mill warehouse discharging mouth 13 be connected with cylindrical shell and be contained in feed back passage 18 and the exit passageway 19 that the discharging spiral tube 17 on the sliding bearing 3 communicates.Lifting body 20 in several lifting sieves 14 is contained in respectively on the burden-guiding cone of center and with exit passageway 19 and communicates.The helical form lifting blade 22 that contains sieve aperture 21 that communicates with helical duct is arranged on the lifting body.On mill storehouse cylindrical shell, bull gear 23 is housed, and by bull gear and transmission mechanism and power source---motor is connected.
