Description
Technical field:
The present invention relates to a kind of preceding precomminution method of mill and the preceding material pre-crushing plant of mill of ball mill, precomminution work station before precomminution method and building station type modularization are ground before especially a kind of ball mill mill.
Background technology:
The theory of " many broken few mills " is extensively admitted in broken mill industry, promptly by before ball mill, increasing the preceding pre-broken equipment of powder (breaking) of mill, to reduce the material size of ball mill, replace fully or the broken function in part instead of ball mill first storehouse, thereby improve ball mill output, cut down the consumption of energy.At present, use hammer mill, column mill unit or roll squeezer system as the mill of ball mill usually before the pre-broken equipment of powder (breaking).But the continuous operating reliability of hammer mill or column mill unit is low, can not be complementary with the higher operating rate of ball mill; Because the broken executive component wearing and tearing of powder (breaking), product granularity is wayward, causes ball mill can not stablize operation; In addition, because the regulating power of hammer mill or column mill unit is poor, to the variation bad adaptability of material strength and abrasion, the variation of material strength directly influences the variation of product granularity; And hammer mill or column mill unit be Open architecture, and environmental pollution is serious; The roll squeezer system has overcome the above-mentioned shortcoming of stand-alone device, it is the main equipment of realizing the preceding pre-broken process program of powder (breaking) of mill at present, its basic craft course is: will need the broken material of powder (breaking) to be transported to roll squeezer by drawing-in device, after the roll squeezer roll-in, form the material cake, break up by beater again, carried out classification by the material after breaing up by selection by winnowing, qualified material enters ball mill, roll-in again after underproof material returns feed arrangement and raw material mixes as pre-powder (breaking) crumble product.Stressed evenly for guaranteeing running roller, the roll-in effect stability requires raw material must contain a certain proportion of fine powder.But also there is following problem in this roll squeezer system: 1. system self circulating load is bigger, generally reach between 200%～300%, in addition low up to 400%, roll-in yield rate, mass transport, to break up the secondary power that needs with classification big, so the energy consumption of unit product is also bigger; 2. system does not carry out integratedly, and process equipment disperses, and structural configuration is strong to the selectivity in place, and the land seizure area is big, and civil engineering requires high, and project is long in the phase of building.
Summary of the invention:
The objective of the invention is to: provide a kind of and can turn round continuously, can be complementary, good reliability and product granularity is stable,, environmentally safe good to the variation adaptability of material strength and abrasion, energy consumption of unit product is little, floor space is little, precomminution work station before precomminution method and the building station type mill before the ball mill of the short construction period mill, to solve the problem that prior art exists with the higher operating rate of ball mill.
The present invention is achieved in that it is provided with the dispensing equipment and the discharging equipment of disintegrating machine and disintegrating machine before ball mill, the raw material that enters ball mill is carried out sending into ball mill after the precrushing, to reduce the material size of ball mill, it is concentrated the dispensing equipment of disintegrating machine and disintegrating machine and discharging equipment and is arranged in the station, building, to improve crushing operation rate, stable prod granularity, be complementary with ball mill.
Station, building factory building adopts full steel structure, and main structure adopts A font rod structure.
The precomminution work station is to constitute like this before the building station type modularization mill of the present invention: it comprises former feed bin, below former feed bin, be provided with the batching metering batcher, the batching metering batcher connects proportioning belt, proportioning belt connects the raw material elevator, the raw material elevator connects feeding belt, feeding belt connects the disintegrating machine drawing-in device, and the disintegrating machine drawing-in device connects disintegrating machine; Be provided with vibratory sieve below disintegrating machine, vibratory sieve connects feed back belt and finished product elevator respectively, and the feed back belt connects the charging aperture of raw material elevator; The finished product elevator connects current stabilization and goes out feed bin, current stabilization go out feed bin below be provided with discharging metering batcher, discharging metering batcher connects outfeed belt, outfeed belt connects the charging aperture of ball mill.
