Abstract

The utility model relates to a self-pressurizing ring groove grinder, a grinding board of which is divided into an upper grinding board (7), a middle grinding board (3), and a lower grinding board (9). The bottom surface of the upper grinding board (7) and the upper side of the middle grinding board (3) are respectively provided with a plurality of ring grooves and are provided with a plurality of ball-shaped grinding bodies (4), and the bottom of the middle grinding board (3) and the upper part of the lower grinding board (9) are also provided with the annular grooves and are provided with a plurality of the ball-shaped grinding bodies. The utility model is mainly used for grinding to materials in the building material industry and the mining industry, and the self-pressurizing ring groove grinder has the main characteristics of obvious energy saving effects, no dusting, low noise, and simple structure.

Description

From the supercharging ring groove mill

The utility model relates to milling equipment.

In the milling equipment that use in building materials and mine, the most universal, historical the longest be tube mill, and the generally tube mill and the vertical grinder of use at present, shortcoming such as it is low all to exist capacity usage ratio, and noise height, dust-laden exhaust gas discharge capacity are big.

The purpose of this utility model promptly is the shortcoming of aspects such as the capacity usage ratio that exists at above-mentioned prior art is low, noise is high, dust-exhausting quantity is big, and provides a kind of from the supercharging ring groove mill.

The purpose of this utility model is achieved through the following technical solutions:

A kind of from the supercharging ring groove mill, mainly constitute by feeding hopper, mill, housing, bearing and motor, power transmission shaft, decelerator, said mill comprises upper millstone (7), middle mill (3) and lower millstone (9), wherein, respectively be provided with the multiple tracks annular groove in upper millstone (7) bottom surface with above the middle mill (3), and in each annular groove, place a plurality of spherical grinding bodies (4), below middle mill (3) and above the lower millstone (9), also have annular groove, and in each annular groove, place a plurality of spherical grinding bodies (4).Middle mill (3) itself can be divided into multilayer, and has a plurality of spherical grinding bodies (4) between each layer.The annular groove cross section of upper millstone (7) bottom surface is V-shaped; Annular groove cross section above the middle mill (3) is the U type.The annular groove cross section that also can be upper millstone (7) bottom surface is the U type, and the annular groove cross section above the middle mill (3) is V-shaped.A plurality of pressure regulators (13) are housed on loam cake (8), and pressure regulator (13) withstands on the last plane of upper millstone (7).Lower millstone (9) is fixed in the shell (10), and lower millstone has the annular groove that the cross section is the U type above (9), has the V-shaped annular groove in cross section below middle mill.

Because the utility model is to adopt direct active force to carry out fragmentation and grinding, energy conversion ratio height, efficient height are insensitive to the moisture of material simultaneously.Material movement is finished by centrifugal force and extruding force in the mill, thereby does not need to carry out gas flow, does not have toxic emission, reduces dust pollution.Because abrasive body is that gerotor type contacts with material, so there is not impact noise, noise pollution can reduce.

In sum, the utlity model has simple in structurely, advantage such as low, the no dust discharge of consuming energy, noise are little is desirable milling equipment.

The drawing of accompanying drawing is described as follows:

Fig. 2 is the cut-away view from the supercharging ring groove mill of the present utility model

Fig. 3 is the vertical view from the supercharging ring groove mill of the present utility model

Fig. 4 is the pressure regulator structure chart

Be described further below in conjunction with drawings and Examples:

The utility model is mainly by feeding hopper 1, and power transmission shaft 2, middle mill 3, abrasive body 4, motor 5, decelerator 6, upper millstone 7, loam cake 8, lower millstone 9, shell 10, bearing 11, support 12, pressure regulator 13, discharging opening 14 constitute.Shell 10 is fixed on the concrete structural bearings 11 by support 12.Lower millstone 9 is fixed in the shell 10.Lower floor's abrasive body 4 (can be one or more groups) places the U-shaped of lower millstone 9 to grind in the annular groove, and the V-arrangement locating slot of middle mill 3 bottoms is pressed on lower floor's spherical grinding body 4, constitutes mill chamber down.Middle mill top can be provided with many group U types and grind annular grooves according to the needs of grainding capacity and fineness.The quantity of U type annular groove is directly proportional with raising fineness and output.Ball-type abrasive body 4 can be determined sphere diameter according to hardness that grinds and fineness requirement, and filling is in U type annular groove.Upper millstone 7 bottoms are provided with the corresponding V-type locating slot of U type annular groove with middle mill 3, are pressed on the abrasive body 4 mill chamber on the formation.Pressure between mill and abrasive body is adjusted by pressure regulator 13.

Function of the present utility model is achieved in that

Upper millstone 7 is a pressure disc, and middle mill 3 is that driving disc spacing pressing, lower millstone 9 are supporting disk, and plays further abrasive action.Middle mill is linked to each other with reductor 6 by power transmission shaft 2, by Motor Drive.

Polished material feeds charging aperture uniformly by feeding hopper 1, ground in the annular groove by the centrifugal force feeding in middle mill 3, and the abrasive body 4 that is rolled constantly rolls and grinds.Under action of centrifugal force, be discharged from mill chamber through the preliminary material of pulverizing.Because last mill chamber is higher than down mill chamber, thereby material is under the gravity effect, after entering down mill chamber again and being continued to grind to form the fineness of requirement, by discharging opening 14 discharge grinding machines.
