Abstract
The utility model discloses a high-pressure mill with an overhang roller, which uses springs to increase pressure. A cover cylinder, an air inlet spiral casing, a grinding ring and a bearing seat are arranged on the base of the utility model; a motor drives grinding rollers and a perching knife which are arranged on a hanging frame of the grinding roller to rotate synchronically; the springs are respectively arranged on each grinding roller component; spring pressing plates which are arranged on the springs are connected with the hanging frame of the grinding roller via screw rods. The high-pressure mill with the overhang roller is suitable for the grinding of non-inflammable non-explosive granular brittle material; the utility model has the advantages that the prepressing of the utility model has labor saving; the contacting positions of the springs and grinding roller components have no abrasion.
Description
The utility model relates to a kind of grinding ore, particularly is fit to the equipment of the various brittle materials of grinding Mohs' hardness below seven grades.
(patent No.: ZL93235802.0), on the bull ring internal circular surfaces, lump material enters along the perching knife inclined-plane between grinding roller and the bull ring and is pulverized grinding roller in roll extrusion under the effect of centrifugal force and spring pressure at existing high pressure overhang roll mill.But, thereby have the following disadvantages owing to only act on simultaneously on several grinding roller parts in the grinding machine with a bigger spring of rigidity: the first, rotate a nut and compress spring to reach about 2000 kilograms precompression more painstaking.The second, because of by comminuting matter granular size difference, make the grinding roller parts be a spot wobble with horizontal axis tam continually, because a spring is pressed on several grinding roller parts simultaneously, therefore, the contact-making surface of spring and each grinding roller parts all has slip when swing, causes contact-making surface easy to wear.
The purpose of this utility model is a kind of high pressure overhang roll mill that designs at above deficiency, and it can avoid the deficiencies in the prior art part effectively.
The purpose of this utility model is achieved in that and is separately installed with cover tube 9, bull ring 11, air intake spiral case 13 and bearing block 15 on the support 12 of high pressure overhang roll mill, perching knife 14 is installed on the shovel power frame 8, relieving tool post 8 connects with grinding roller suspension bracket 5 and together is sleeved on the main shaft 16, grinding roller parts 6 are suspended on the grinding roller suspension bracket 5 by cross-arm auxilliary 7, wherein, on each grinding roller parts 6 spring 3 is housed all, spring bearer plate 2 is housed on the spring 3, spring bearer plate 2 connects with grinding roller suspension bracket 5 by screw rod 4.
The utility model also can be achieved in that compression spring 3 all is housed on each grinding roller parts 6.
The utility model can also be achieved in that spring bearer plate 2 and grinding roller suspension bracket 5 are connected and fixed by screw rod 4 usefulness nuts.
The utility model is born by several screw rods respectively because of total precompression of several springs, so, when the compression spring, just more laborsaving by the root stretching screw, overcome and only used the bigger spring precompressed of rigidity painstaking in the prior art, the stressed all around unbalanced numbness disease of spring.In addition because the utility model has all been installed a spring on each grinding roller parts, so, when the grinding roller parts when horizontal axis tam is swung, spring and the contact-making surface of grinding roller parts do not have relative slip just not easy to wear yet.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the cutaway view according to the high pressure overhang roll mill that the utility model proposes.(annotate: the base bearing part is not cut open)
Number in the figure is represented:
1-fineness grader; The 2-spring bearer plate; The 3-spring; The 4-screw rod;
5-grinding roller suspension bracket; 6-grinding roller parts; The 7-horizontal axis tam; The 8-relieving tool post;

13-air intake spiral case; The 14-perching knife; The 15-bearing block; The 16-main shaft;
The 17-loading hopper; The 18-air inlet.
The utility model is described in further detail below in conjunction with Fig. 1:
Be separately installed with cover tube (9), bull ring (11), air intake spiral case (13) and bearing block (15) on the support (12), perching knife (14) is installed on the relieving tool post (8), relieving tool post (8) connects with grinding roller suspension bracket (5) and together is sleeved on the main shaft (16), grinding roller parts (6) are suspended on the grinding roller suspension bracket (5) by horizontal axis tam (7), spring (3) is installed on the grinding roller parts (6), and spring bearer plate (2) is contained in spring (3) and upward and by screw rod (4) connects with grinding roller suspension bracket (5).
Motor drives main shaft (16) rotation by speed reduction gearing, and main shaft (16) drives grinding roller parts (6) and perching knife (14) rotation synchronously by grinding roller suspension bracket (5).Grinding roller (10) tightly is pressed on the inner surface of bull ring (11) under the effect of centrifugal force and spring (3), and when rolling in its surface around self axle rotation.By abrasive particle shape material in loading hopper (17) adding machine, scooped up by perching knife (14), and enter along the inclined-plane of perching knife (14) between grinding roller (10) and the bull ring (11) by roll extrusion, rub with the hands broken, enter in the grinding machine from support (12) hole on every side after air inlet (18) enters air intake spiral case (13) from the air stream that air blast is sent here, bring pulverized material into fineness grader (1) internal classification, the material that particle is big falls to be refaced, fine powder then enters in the cyclone separator with air-flow and is collected out, and the air stream that is cleaned turns back to air blast again and repeats with cocycle.
Claims (3)
