The cement of product skewed slot 12 feeds finished product skewed slot 15 together, and the mill inner ventilation of ball mill 13 is through grinding tail dust-precipitator 16 and mill tail gathers dust wind
Machine 17 is discharged into chimney 11.
The present invention is in order to realize regulation finished cement size distribution, improve " paste ball " phenomenon in mill, improve grinding in mill
Efficiency, the pollution of noise, reduction to finished product of ball mill in the process of running is reduced, and then realize reduction Vertical Mill pregrinding system
Unit power consumption, improve the performance of finished cement, reduce harm of the noise to operator and surrounding environment, ground using nonmetallic
Grinding media is as abrasive media.
Ball milling grinding system is flowed for circle, mill feed material size is 95%≤25mm, 100%≤50mm, material in mill
The percussion mainly by the steel ball fallen is crushed, also the abrasive action of relying part point.Therefore, using the larger steel ball of unit weight to grind
Grinding media can more play percussion of the abrasive body to material.And pass through the extruding of Vertical Mill 4 for Vertical Mill pregrinding system, material
Enter ball mill 13 after crushing.After extruding, raw meal particle size reduces, and the crack increase of material, grindability improve.Therefore Vertical Mill
The crushing of material is based on grinding in mill in pregrinding system, with little need for impact of the abrasive body to material.Therefore, for vertical
Pregrinding system is ground, uses the less non-metal grinding medium of unit weight to replace traditional steel ball or steel forging to be filled for abrasive media
Abrasive action of the non-metal grinding medium to material is waved in distribution.Meanwhile the operation power of grinding machine and the unit weight of abrasive body are proportional
Relation, traditional steel ball or steel forging are replaced as abrasive media, ball mill operation using the less non-metal grinding medium of unit weight
Power can reduce by 40%~60%, and the unit power consumption of system can reduce by 8%~15%.
Traditional abrasive media steel ball or steel forging are process by casting, and thin material is easier to adsorb in steel ball or steel forging
Surface, form " paste ball " phenomenon.And non-metal grinding medium is formed using high-temperature firing, surface is smooth, in identical grinding operating mode
Under, the absorption to fine powder material can be reduced.During grinding to identical specific surface area, non-metal grinding medium surface " paste ball " phenomenon is bright
It is aobvious to improve, so as to improve the grinding efficiency in ball mill.
The cylinder lining plate of ball mill 13 is used based on high-chromium cast liner plate mostly at present, and abrasive media uses Gao Ge mostly
Steel ball or steel forging.In grinding machine running, abrasive body strikes the collision on hard liner plate or between abrasive body, can all produce
Raw strong noise.The unit weight of abrasive body is bigger, and caused noise is bigger.And non-metal grinding medium ball unit weight is small, only 1.9
~2.2t/m3, it is the 40%~50% of steel ball or steel forging, therefore the ball mill using non-metal grinding medium as abrasive media is crushing
The noise that collision during material between impact of the abrasive body to liner plate and material, abrasive body is formed substantially reduces, and reduces to behaviour
Make the harm of worker and surrounding environment.
In summary, the present invention is less nonmetallic by unit weight by the abrasive media in Vertical Mill pregrinding system in ball mill
Abrasive media, instead of traditional steel ball or steel forging, the grinding efficiency in mill can be improved, improves " paste ball " phenomenon in mill, and can
Finished cement size distribution is adjusted, improves cement water requirement.Meanwhile ball mill noise in the process of running can be reduced, reduced
Pollution to finished product.
Although the preferred embodiment of the present invention is described above in conjunction with accompanying drawing, the invention is not limited in above-mentioned
Embodiment, above-mentioned embodiment is only schematical, is not restricted, the common skill of this area
Art personnel are under the enlightenment of the present invention, can be with the case of present inventive concept and scope of the claimed protection is not departed from
Many forms are made, these are belonged within protection scope of the present invention.
