Abstract
The utility model discloses a pressure mill with hanging rollers which can simultaneously complete the milling and the grading of the block type materials. The grading of the pressure mill adopts a no rotor air classifier, and the milling roll adopts a split structure. The milling roll shaft is sheathed with a milling roll core and a milling roll central core, the exicircles of which are sheathed with two up-down parallel milling roll sleeves with the same shape. A pressure spring is sheathed in the upper end of a main shaft, and a screw nut is arranged on a spring. The suspension arm of a milling roll bearing chamber is extended to the excircle of the main shaft and under the pressure spring, to make the roller force unchanged, so that the constant output is realized. A perching knife rack and a milling roll hanger are fixedly connected with the main shaft, and the perching knife is fixed on the perching knife rack, so that the utility model has the advantages of small size and low cost.
Description
The utility model relates to the unit equipment of a kind of grinding and classification, particularly a kind of high pressure overhang roll mill, and it is fit to the various brittle materials of grinding Mohs' hardness below seven grades, and can disposablely reach fineness requirement.
Existing grinding machine kind is more, and its pluses and minuses and the scope of application thereof are respectively arranged, and wherein Raymond mill (R type pendulum roller type flour mill) with its efficient height, once becomes powder, and advantages such as finished product epigranular occupy front two in China's sales volume name.But this grinding machine only is to utilize centrifugal force to make the grinding roller roll extrusion on the bull ring inner surface, and centrifugal force is directly proportional with the quality and the radius of grinding roller, with square being directly proportional of rotating speed, can increase centrifugal force though improve rotating speed, but vibratory output and noise also can increase, especially vibrate conference and seriously shorten the service life of machine, noise greatly then can influence workman's physical and mental health.If increase the quality and the radius of gyration, then can make grinding machine cost height, difficulty of processing is big.When grinding roller wearing and tearing were little, centrifugal force reduced, and its output also can descend thereupon, grinding roller and bull ring middle part fast than the two ends wearing and tearing always in use in addition, and the gap, middle part that grinding roller is contacted with bull ring is increasing, and output is also more and more lower.
What at present the grader on the grinding machine top of using adopted is leaf grating rotor-type gas flow sizing machine, must adapted bevel gear reduction box and stepless speed-regulating motor can realize stepless classification, this structure is cost height but also consumed power not only, it is bigger to maintain difficulty simultaneously.This machine can only sub-elect the granularity in the 80 orders-325 order scope in addition, though small-sized Raymond mill adopts bead apex to take turns direct transmission, can not realize stepless classification to the finished product granularity.
The purpose of this utility model is that design at above deficiency a kind of can carry out the high pressure overhang roll mill that grinding and classification are finished simultaneously to lump material, and what its clasfficiator adopted is the air classifier of no rotor; Grinding roller has adopted the branch body structure; High-pressure system has adopted compression spring, makes roll extrusion power constant, thereby realizes that productivity ratio is constant, and relieving tool post of the present utility model is directly to contact with main shaft, and by adding flat key cooperation connection, so volume is little, and cost is low.
The utility model is achieved in that the right-hand member at high pressure overhang roll grinding machine frame 28 is equipped with vertical machine 27, bead apex 26, main shaft bearing chamber 25 are housed on the main shaft 17 of frame 28 left ends, grinding roller 18 and high-pressure system are housed on support 24, no rotor air classifier is contained in the case 8, wherein, relieving tool post 21 and grinding roller suspension bracket 15 are fixedly connected on main shaft 17, the perching knife 23 that is certain inclination angle with level is fixedly connected on relieving tool post 21, the grinding roller assembly is hinged by horizontal axis tam 16 and grinding roller suspension bracket 15, and grinding roller 18 is fitted on the inner surface of bull ring 20.Compression spring 12 is sleeved on the upper end of main shaft 17, and nut 11 is contained on the compression spring 12, and the cantilever of grinding roller bearing chamber 14 extends to the cylindrical of main shaft 17, and compression spring 12 times.Be set with grinding roller core 30 on grinding roller axle 29, grinding roller SMIS 32 is set with the identical grinding roller cover 31 of two shapes arranged side by side up and down on the cylindrical of grinding roller core 30 and grinding roller SMIS 32.Be fitted with interpolation pipe 2 in the escape pipe 1 of no rotor air classifier, pull bar 4 hangs on the snap ring 3, snap ring 3 is sleeved on the escape pipe 1, air channel base plate 9 and cylinder circular cone tube 10 are for being fixedly connected, the lower end of rotating shaft 6 is inserted on the air channel base plate 9, upper plate and link mechanism 5 that case 8 is passed in the upper end of rotating shaft 6 link, and guide plate 7 and rotating shaft 6 are for being fixedly connected.
The utility model also can be achieved in that between the upper plate of guide plate 7 and case 8 and the air channel base plate 9 and form rectangular channel.
The utility model can also be achieved in that the internal circular surfaces of the grinding rollers cover 31 that two shapes are identical is two two-way cones, and the cylindrical tapering of grinding roller core 30 and grinding roller SMIS 32 is identical with the female cone degree of grinding roller cover 31.
The utility model with the advantage that existing grinding machine is compared is:
What 1, high-pressure system of the present utility model adopted is compression spring, and the production efficiency of the grinding machine of same size is increased substantially.When grinding roller has been worn little, can keeps roll extrusion power constant by screwing spring nut, thereby realize that productivity ratio is constant.
What 2, grinding roller of the present utility model adopted is the branch body structure, grinding roller is with two identical grinding roller covers, its internal circular surfaces is two two-way cones, when grinding roller cylindrical middle part is worn when recessed, two grinding roller covers can be inverted respectively or be exchanged, can make the grinding roller wearing and tearing so evenly, stable yield, and prolonged the service life of grinding roller cover, improved the utilization rate of steel.
3, relieving tool post of the present utility model and main shaft are directly to contact and cooperate and connect by adding flat key, so this grinding machine volume is little, the grinding machine overall dimensions with same specification grinding roller is dwindled, thereby manufacturing cost is reduced significantly.
What 4, clasfficiator of the present utility model adopted is no rotor air classifier, so this machined piece is few, rolled steel dosage is few, and cost is low, and saves energy.
