Collect through slot 16 in, it is ensured that when material run discharge by No.1 storehouse outlet 22 discharging when can smoothly enter into discharging bin 18,
And be finally discharged by discharge port 24, it can also go out in discharge port 24 and connect extraneous dust-precipitator, borrow principle of negative pressure and carry out discharge, row
Material is more quickly, thoroughly.
Bracket 1 is detachable structure in the present invention, can also unload replacement to improve the degree of stability of its operation when use
At reinforced concrete structure pedestal, whole vibratility is reduced, noise is reduced, prolongs the service life.
Working principle: when the invention works, user first powers on motor 20, later puts the material of required milling
Entering in material feeding box 5, starts motor 20, treating material is fallen by material feeding box 5 to be entered in the No.1 storehouse 6 in left end storehouse 7, after
It is continuous be dropped through cracking cabin charging and lead mouth 2 enter in broken mill storehouse 25, carry out broken process, with the entrance of material, be crushed into
The beginning of journey, material starts to carry out circular motion along central rotating shaft along with broken mill storehouse 25, finally by the cracking cabin of the other end
23 discharge of outlet is led in the entrance of mouth 19 in fine grinding storehouse 13 by the charging of middle fine grinding storehouse later into No. two storehouses 8 in right end storehouse 15,
Expansion further grinds process, is then discharged into No. two storehouses 8 in left end storehouse 7 by middle fine grinding storehouse outlet 10, then pass through height
The charging of fine grinding storehouse is led mouth 9 and is entered in Super-fine grinder storehouse 11, and final Super-fine grinder powder process is unfolded, is exported after the completion by Super-fine grinder storehouse
14 are discharged into the No.1 storehouse 6 in right end storehouse 15, after filtering via steel strainer 17, pass through No.1 storehouse outlet 22 and enter discharging bin 18
In, and overall process can be completed by the discharge of discharge port 24.
In conclusion the thin integrated mill lining plate 12 of three circles of the height cooperatively forms abrasive body with steel ball 27, cooperate broken mill storehouse 25,
Distribution refinement is realized in Super-fine grinder storehouse 11 and middle fine grinding storehouse 13, and milling effect is more preferable, also achieves a possibility that working continuously, discharge
When the center convolution way of output, meet discharge continuity carry out, substantially increase the working efficiency of grinding machine, use simultaneously
The concentric circles principles of three circle one, cleverly by milling process be divided into it is broken, in thin and height it is thin, crushing effect is more preferable, concentric circles
Operation logic, construction milling process in it is more laborsaving, it is energy saving, reduce operating cost, shorten entire length, take up an area
Area is smaller, facilitates placement and use.
