Abstract

The utility model discloses a centrifugal roller compacted mill suitable for crushing middle or low hardness materials, wherein a main shaft 15 thereof is vertically arranged on the middle of a cylinder 17, and a plate hammer crushing cavity, a hopper cavity, a grinding base crushing cavity and a material outlet cavity are orderly arranged from up to down along the main shaft 15. A plate hammer and a gear lining plate 2 are arranged in the plate hammer crushing cavity, two groups of dynamic grinding bases and static grinding bases are arranged in the grinding base crushing cavity, crushing balls are put in rails between the dynamic grinding bases and the static grinding bases, and a middle hopper is arranged between the plate hammer crushing cavity and the grinding base crushing cavity. The centrifugal roller compacted mill has large crushing radio, and can reach a maximal particle size which is 40mm, and the particle size which is smaller than 2mm is above 98 percent. The volume of the centrifugal roller compacted mil is small, compared with a ball mill with the same grinding amount, the volume of the centrifugal roller compacted mill is from one twice to one third of the ball mill. The centrifugal roller compacted mill steadily operates, has low mounting fundamental demand, convenient mounting and maintenance, less over-crushing, short residence time of materials in the centrifugal roller compacted mill and rapid outlet materials. The centrifugal roller compacted mill can crush materials in a dry mode, and also can crush materials in a wet mode.

Description

The centrifugal grinding machine that rolls

Affiliated technical field

The utility model relates to a kind of middle soft material disintegrating apparatus, the especially centrifugal grinding machine that rolls.

Background technology

Existing powder grinding machine is wanted comminuting matter, all is to repeat fragmentation, yields poorly, power consumption is big; Add the man-hour material and beat on liner plate, make the metal consumption of liner plate, bar big; And dry type comminuting matter only, can not the case of wet attrition material; Complexity is installed, maintenance and inconvenient.

Summary of the invention

For overcoming above-mentioned deficiency, the utility model provides a kind of centrifugal grinding machine that rolls.

The technical solution adopted for the present invention to solve the technical problems is: the centrifugal grinding machine that rolls is made up of main shaft 15, bar 3, tooth liner plate 2, moving mill disc, quiet mill disc, stone roller ball, material toggling dish, its main shaft 15 vertically is arranged in the middle of the cylindrical shell 17, be furnished with bar crusher chamber, funnel chamber, mill disc crusher chamber and discharging chamber from top to bottom successively along main shaft 15, wherein:

The bar crusher chamber: rotor 20 is installed in main shaft 15, and bar 3 is installed on the rotor 20, and bar 3 outer periphery are equipped with tooth liner plate 2;

Funnel chamber: with main shaft 15 is that the center is equipped with conical middle funnel 19, and middle funnel 19 upper ends are communicated with the bar crusher chamber, and the lower end is communicated with the mill disc crusher chamber, at last

quiet mill disc

4 and 19 in middle funnel spring 18 is installed;

The mill disc crusher chamber: be provided with two groups of moving mills disc and quiet mill disc in the mill disc crusher chamber, upward moving mill disc 6 and following moving mill disc 7 are installed on the main shaft 15 by rotor; Go up quiet mill disc 4 and place moving mill disc 6 tops, go up quiet mill disc 4 and last moving mill disc 6 opposite faces and have track, grind ball 5 and place in the track; Quiet mill disc 8 places down moving mill disc 7 belows down, and following quiet mill disc 8 and following moving mill disc 7 below opposite faces have track, place in the track and grind ball; Along last quiet mill disc 4 and last moving mill disc 6 outer walls, be provided with granularity controller 16;

The discharging chamber: material toggling dish 10 is installed on the main shaft 15 by rotor.

The beneficial effects of the utility model are: the ratio of reduction is big, and maximum material size can reach 40mm, and discharging-material size accounts for more than 98% less than 2mm's; Installed capacity is little, and the ball mill identical with the ore grinding amount compared, and installed capacity of the present utility model only is the 1/2-1/3 of ball mill; Equipment operates steadily, and the basis is installed requires low, convenient for installation and maintenance; Cross to pulverize and lack, the time of staying of material in this machine is short, and discharging is fast; But both dry type comminuting matters also can the case of wet attrition material.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation.

1. feed hoppers among the figure, 2. tooth liner plate, 3. bar is 4. gone up quiet mill disc, 5. stone roller ball, 6. on moving mill disc, 7. time moving mill disc, 8. time quiet mill disc, 9. discharging opening, 10. material toggling dish, 11. big belt pulleys, 12. belt, 13. small belt pulleys, 14. motor, 15. main shaft, 16. granularity controllers, 17. cylindrical shells, 18. spring, 19. middle funnels, 20. rotors.

The specific embodiment

Motor 14 drives main shafts 15 and rotates by small belt pulley 13, belt 12, big belt pulley 11, bar 3, upward moving mill disc 6, moving mill disc 7, material toggling dish 10 grind ball rotation on one side in orbit with rotor rotation down, on one side around main shaft 15 revolution.Material falls into from feed hopper 1, and at first by bar 3 fragmentations, the material after the fragmentation enters between the track of quiet mill disc 4 and upward moving mill disc 6 opposite faces through middle funnel 19, is ground ball 5 to roll fragmentation.Granularity is less than the material in gap between last moving mill disc 6 outer walls and the granularity controller 16, falls into quiet mill disc 8 and is broken once more between the moving mill disc 7 down in action of centrifugal force.Last under the effect of material toggling dish 10, get rid of by discharging opening 9.The material of soft (Polodyakonov coefficient is less than 10) can reach 60% ,-200 purpose materials less than 100 purpose materials and can reach 40% behind this machine three-crushing.
