Abstract

The utility model relates to a high pressure roll-grinding machine, comprising a middle and a lower box bodies, a belt pulley, a main spindle, a bearing seat, a feed inlet, a discharge outlet, a lining ring, and a grinding roller. A separating disk and a supporter are arranged in the lower part of the main spindle. A spring seat, a spring spindle, and a spring are arranged at the bottom face of the separating disk. One end of the spring spindle is sheathed in the trepan boring of the spring seat, and the other end contacts with the upper part of a swing arm. A spring is sheathed on the external part of the spring spindle. The both ends of the spring respectively contact with the upper parts of the end face of the spring spindle and the spring seat. The utility model has the advantages of simple structure, small vibration and noise, high grinding efficiency, long service life, and good performance.

Description

High-pressure roller mill

The utility model relates to a kind of grinding machine equipment, is specifically related to the high-pressure roller mill that a kind of grinding Mohs' hardness is not more than 7 grades various mineral products materials.

Existing flour mill kind is more, pluses and minuses and accommodation thereof are respectively arranged, wherein its structure of Raymond mill (R type pendulum roller type flour mill) is: utilize centrifugal force to make grinding roller roll extrusion on the bull ring inner surface, roll the material between grinding roller and the bull ring, and make it to become fine powder, by leaf grating rotor gas flow sizing machine the fine powder in the 80-325 order scope is sent then, this Raymond mill only is the mineral of milling of the centrifugal force when utilizing grinding roller to rotate, therefore, expect bigger ore grinding power, just must improve the rotating speed of grinding roller or the quality and the radius of gyration of increase grinding roller, like this, its vibratory output and noise also increase thereupon, and especially vibrating when big can the serious service life that shortens machine, noise greatly then influences surrounding environment, and the infringement workman is healthy.

The purpose of the utility model aims to provide a kind of high-pressure roller mill that very high rotating speed can obtain very big ore grinding power, improves the grinding machine grinding efficiency, reduces vibratory output, reduces noise, prolongs grinding roller and lining ring life-span, technical performance is good that need not.

Technical solution of the present utility model is: this high-pressure roller mill, belt pulley by motor-driven machine top drives the main shaft that connects with it, spreading disk and support are equipped with in the main shaft bottom, bearing block is installed on the middle casing, the seat bottom surface of bearing block is provided with charging aperture, middle casing and lower box are connected and fixed, lining ring is housed in the lower box, the spreading disk bottom surface is equipped with spring base, spring spindle one end is enclosed within the trepanning of spring base, the spring spindle other end withstands on the rocking arm, and spring housing is in the spring spindle outside, both ends of the spring withstand on the spring spindle end face respectively and spring base on.

Simultaneously, also have screw hole on the rocking arm, suit is adjusted screw, adjust the screw hole screw thread screwed connection of screw and rocking arm, an end of adjusting screw withstands on the support, and screw is adjusted in rotation, make it turn up and down in screw hole, the top power of adjusting screw can change the gap of grinding roller and lining ring.

Like this, material enters in the grinding machine by charging aperture, spreading disk is distributed to material in the working chamber, rolling and become fine powder between grinding roller by rotation in working chamber and the lining ring, discharge from discharge gate at last, because the utility model adopts the structural design that each grinding roller is pressurizeed separately, increased the grinding efficiency of grinding machine, make grinding machine work need not very high rotating speed, can obtain very big ore grinding power, meanwhile, the utility model also adopts to be adjusted screw and regulates gap between grinding roller and the lining ring, during work, always have certain clearance between grinding roller and the lining ring, can directly not contact, therefore, grinding roller and lining ring do not have directly collision and violent wearing and tearing, have so just reduced the operating noise mechanical oscillation, have prolonged the life-span of grinding roller and lining ring yet.The utility model is simple in structure, easy to manufacture, reasonable in design, function admirable.

Fig. 1 is the utility model structure longitudinal sectional view.

Below in conjunction with accompanying drawing the utility model is further described in detail:

Referring to Fig. 1; The power of this high-pressure roller mill is by motor-driven; Motor belt drives belt pulley 1 and rotates; Belt pulley 1 is installed in main shaft 4 upper ends; Bearing block 2 is installed on the middle casing 14; Device has charging aperture 3 on the seat bottom surface of bearing block 2; Belt pulley 1 connects with main shaft; Belt pulley 1 drives main shaft and rotates; Bottom fixed installation spreading disk 5 and the support 15 of main shaft 4; The bottom surface of spreading disk 5 is equipped with spring base 17; Adopt screw to connect between the two; Mounting spring 16 and spring spindle 6 on the spring base; One end of spring spindle 6 is enclosed within the trepanning of spring base 17; Spring spindle 6 can pass in and out mobile in the trepanning of spring base; The other end of spring spindle 6 withstands on the rocking arm 9; Spring 16 is enclosed within the periphery of spring spindle 6; Spring 16 is stage clip; One side pressure of spring 16 is on the end face of spring spindle 6; The other end of spring 16 withstands on the spring base 17; Like this; Spring 16 is by 9 pressurizations of 6 pairs of rocking arms of spring spindle; Rocking arm 9 passes through bearing pin 8 twisted branchs on support 15; And can be a spot wobble by bearing pin 8; The bottom of rocking arm 9 is installed with grinding roller 10; Grinding roller is connected by little axle 18 with rocking arm; Grinding roller 10 both can revolve round the sun with main shaft 4; Again can be with little axle 18 rotations in the rocking arm 9; Has screw hole on the rocking arm 9; Be set with and adjust screw 7; An end of adjusting screw 7 withstands on the support 15; The screw hole that adjustment screw 7 is sleeved on rocking arm 9 connects by screw thread; Therefore screw 7 is adjusted in rotation; Can change the gap between grinding roller 10 and the lining ring 11; Lining ring 11 is installed in the lower box 13; Lower box 13 lower ends are fixedly connected with discharge gate 12; Lower box 13 is fixedly connected with middle casing 14, above-mentioned main shaft 4; Spreading disk 5; Spring spindle 6; Adjust screw 7; Bearing pin 8; Rocking arm 9; Grinding roller 10; Lining ring 11; Support 15; Spring 16; Spring base 17; Little axle 18 is installed in casing 13; In 14.
