How does the vertical mill realize the energy conservation highly effective powder body profession to hold the dominant position in the foundation profession.The powder body profession uses the multiform breaker, the grinding machine, its power consumption is huge, occupies the national total electricity consumption above 45_; If each ton powder rubs the electricity which, the powder body saves to consume is 10 kwh, the Chinese every year's energy conservation benefit will be huge.At present domestic started to invest the large amount of money to use internationally the advanced vertical grinding machine to enter the powder to rub in the profession, achieved certain energy conservation effect, the professional proposed “broken little rubs” “rubbed by the broken generation” the scientific research item like mushroom growth comprehensive makeshift bed on the ground to open, will create writes up the big benefit occurrence.

After five year research and development original creation Li from crusher machine, Li vertical mill, already succeeded enters in the big industrial production testing, the full confirmation from crusher machine, the autogenous tumbling mill has the high energy conservation, the high benefit international advanced standard.It produces the energy conservation benefit will be does not have may estimate, for example, in 2005 our country cement ultimate output 1,000,000,000 tons, but in Our company's equipment experiment each ton cement only consumes electricity 15 kwh (the present 42 .5# cement to consume electricity 35 kwh ~42 kwh), may above electricity saving 20 kwh, 1,000,000,000 tons cement accumulate equally may the electricity saving 20,000,000,000 kwh electricity, the reduced Renminbi 10,000,000,000 Yuan, according to our country present condition, profession and so on metallurgy, mine, chemical industry, electric power, non-ore powder rubs, the powder body, distantly to surpass the cement profession the total power consumption.Obviously, this equipment's application value is incomparable, will create the huge energy conservation benefit for the country.Li from crusher machine, the Li vertical grinding machine's appearance will bring the powder to rub, in the powder body profession a huge industrial revolution.

First, new machine invention and new machine principle

1. new machine invention

Mentality origin: Stems from the life the centrifugal force application natural principle, the impact type breaker, the powder body profession jet mill and internationally the advanced vertical grinding machine and so on.Invention Li from crusher machine, the Li vertical mill, Li chooses the powder to receive the dust machine (in the experiment), already applied in Jiangsu Province Nanjing three dragon group Mt. Qinglong Cement plant production industry line experiment (present from crusher machine, autogenous tumbling mill has obtained encouraging success, and has sold).If from crusher machine, the autogenous tumbling mill will apply the existing cement production line equipment to transform (ball mill production line), but electricity saving 15 kw. above H/T cement.

2. new machine principle

(1) Li from crusher machine
Using two scrutinize to the revolving centrifugal force launch material, this structure can cause the material to push naturally accumulates the hammer capitate, is launched between the material which and the material by previous the material impact, clashes has the velocity stack, its speed may amount to for 150~200 meters/seconds.The feeding granularity ≤50㎜ massive material instantaneous may become is smaller than stave the 1mm pellet and powdery.
(2) Li vertical mill
Uses using the centrifugal force scrutinizes to the revolving launch material, supposes the material which in the system in each plate forms to pile in the hit the plate to launch the material, the material clashes the speed practice superimposition, to achieve the subsonic speed, the speed of sound.Feeding granularity ≤5 mm, leaves material granularity <0.05 mm to occupy 46%,<0.08mm to occupy 22%,<0.08~0.5mm to account for 32%, achieves 200 item of above thin powder lots, the powdery material.
(3) Li chooses the powder to receive the dust machine
Still in experiment.

Second, new machine characteristic

1. the energy conservation, the nodal wood, save the occupying land area, the save on investment
(1) nodal wood: Non-grinds the body, not to have the medium, the installation weight to be light, compares with the same output's ball mill may save 100 tons ~300 ton steel products and the vulnerable material consumptions.
(2) conserves energy: In the cement flour rubs in the process to be possible above the electricity saving 20KW.H/T cement.The gangue, the steel slag powder rub may above electricity saving 70KW.H/T (compare with ball mill).
(3) saves the occupying land area: The area is only ball mill's area 30_
(4) save on investment: The entire strip cement production line is only ball mill production line's 60_
2. the powder rubs each material, compatible
Like gangue, steel slag, chamotte, quartzite, fluorspar and so on ultra hard material.
3. the powder rubs the grain shape finely (sphere to account for quantity in a big way)
4. stave, the powder rubs compared to a big way, the powder body output is big, the ultra fine dust, the fine powder, the ultra fine powder (because of speed superimposition, material clashes strength to increase to 2~3 times, machine operation speed has not increased).
5. may be higher than two above conventional breaker effect from the crusher machine work effect.

Three. Fine security, reliability.

1. protects oneself to design
From crusher machine, the autogenous tumbling mill uses scrutinizes to the revolving structural design, the outside offers speed slow, in the plate speed is quick, when the machine has the accident, in the working chamber, in the outside offers bumps into natural elimination it to dash the strength, serves the security reliable use purpose.
2. uses the precise transmission
To this machine carries on the transmission using the speed reducer, in the equipment manufacture uses the precise grade of fit, causes when the machine operation the power consumption are few, the noise is small, the work is steady.
3. bad stave, the powder rubs the working conditions the change, causes it to have the movement reliability
In the equipment manufacture the precision enhancement, does not have the medium, non-to grind the body to dash, but is the material and the material carries on dashes, in its process in natural conservation equipment work stability, enables it to achieve the movement the reliability.
