Description
The utility model is the free flour mill of a kind of efficient function, belongs to the manufacture of cement plant equipment, can be used in chemical industry, metallurgy, the refractory material production field, particularly manufacture of cement.
Traditional flour mill generally is divided into one-level or secondary grinding, in order to improve grinding fineness, raise the efficiency and also adopt comparatively complicated closed type grinding, common shortcoming of existing grinding machine ubiquity is can not in time select fine powder in grinding process, cause abrasive body rationally the utmost point join, the function of each logical sequence is hard to tell, and material can not be fully levigate.Though occurred Super-fine grinder at present, solved fine grinding basically, reasonable not enough on principle and the structure, so do not reach best effect.Patent 85106781 as United States Patent (USP) VS3964717, Hefei designing institute is Super-fine grinder, its structure is to set up a material separating device in the normal mill trunk, this device is to be positioned in two logical sequences to be connected by grate plate, blind plate, center vent, make it to have formed material separating device and screening plant, played sieving actoion and material fine grinding basically.But still exist low, the thick material of mill efficiency fully fragmentation just enter down logical sequence, owing to set up powder section separator in the trunk thereby increase flow resistance, because the ventilation filter area is little, usually can cause sticky liner plate and grate plate simultaneously in addition.Its reason is, though 1, the grate plate that enters screening plant all has the overflow type hole, the area that actual material passes through has 50%, thereby influences ventilation and cause and stick with paste the grate plate phenomenon; 2, because the thick material that is sized out just falls into when returning two logical sequences under the grate plate root, following fragmentation that reaches is pushed into screening washer again, causes vicious circle, thereby has strengthened two logical sequence rate of load condensates, has reduced output, full mill occurs; 3, because the screening plant discharge end all is a blind plate, cause material moisture content will occur sticking with paste grate plate slightly greatly, grinding machine can not be run well.4, because when in original grinder cylinder body, having set up screening plant material being flowed forward, increased flow resistance, the qualified material of a logical sequence and two logical sequences can not in time be passed through, the part material occurred and crossed grinding and gather, glue grate plate, shirt plate, increase the mill internal resistance, thereby reduced efficient.
The purpose of this utility model is to solve the problem that existing grinding machine exists, and proposes a kind of novel free flour mill of efficient function, realizes Super-fine grinder, high-quality, high efficiency, reduces power consumption.
Major technique content of the present utility model is, this machine is to undergo technological transformation in original one-level open-circuit grinding machine, by the change of grinding machine internal structure, the change of abrasive body, reach functional classification, automatic screening, thereby reach high yield, high thin, low power consumption, solve material and cross grinding, the thick phenomenon of sticking with paste the comb liner plate of considering to be worth doing.
This flour mill is made up of trunk 17, feed end 1, discharge end 9; Feed end is provided with pressure blower 2; Be equipped with in the trunk 17 every logical sequence plate 3 trunk is divided into first logical sequence and second logical sequence, a functional classification is set in second logical sequence, make second logical sequence form two and grind that logical sequences are ground logical sequences promptly and logical sequence is ground in the back from screening device 8; Classification is by feed end grate plate 14, feed end blind plate 5 from screening device 8, discharge end grate plate 7, discharge end blind plate 10, and air inducing scraping wings 13, sieve plate 12, sliding plate 6, two-way anti-material awl 11, burden-guiding cone 15 are formed; The grate plate of feed end grate plate and blind plate, discharge end and blind plate constitute two feed end garden dish 18 and discharge end garden dishes 19 with center vent respectively, and grind between the logical sequence grinding logical sequence and back before laying respectively at, and be fixed on the trunk; The feed end garden is coiled between 18 left side feed end blind plates and the grate plate lifting blade 4 is housed, and riser 17 is housed on the lifting blade 4, and the center vent place is embedded with burden-guiding cone 15; The charging garden coil between 18 feed end blind plates and the grate plate and the discharge end grate plate of discharge end garden dish 19 and blind plate between camber sieve plate 12 and sliding plate 6 are housed; The center vent of feed end garden dish 18 and discharge end garden dish 19 is embedded with air inducing scraping wings 13, and the outside is welded with two-way anti-material awl 14.
Technique effect of the present utility model is, the free flour mill of this efficient functional classification, owing to the pressure blower is housed at feeding end, this blower can solve that a logical sequence occurs in the former tradition open circuit mill crosses the grinding phenomenon, make qualified material and send into down the logical sequence grinding fast, thereby alleviate the rate of load condensate of a logical sequence, overcame the grinding phenomenon.Coalescent and the sticky grate plate that causes influences the shortcoming of output.
Functional classification is housed from screening device in this grinding machine second logical sequence in addition, two logical sequences are divided into former and later two grind logical sequence, the material by first logical sequence is come enters sieve plate through the feed end grate plate and screens, qualified material is sent into the back and is ground logical sequence under the slide plate effect, grind logical sequence in the back and continue to grind; Underproof material by anti-material bore, burden-guiding cone grinds logical sequence before returning, and throws again brokenly at the following material of the effect of lifting blade and abrasive body, so finishes the sizing screening grinding of material repeatedly, to make material reach qualified till.Therefore, this grinding machine has efficient function, grinding fineness is thin, the cement granules specific area is big, energy-saving advantages can be used for high-mark cement, and high-early (strength) cement in the production of special cement, also can be used for industries such as chemical industry, metallurgy.
