Description
Technical field
The utility model relates to a kind of cement half final grinding system, is particularly with cement half final grinding system of current stabilization metering device.
Background technology
In cement grinding field, tube mill due to capacity usage ratio and mill efficiency low, progressively replaced by efficient bed of material milling equipment in energy-conservation grinding.Vertical Mill, roll squeezer are all bed of material milling equipments, and mill efficiency is higher.Vertical Mill, roll squeezer pregrinding system are the main flow of cement grinding technology at present, on the basis of ball mill, realize significantly carrying and produce with energy-conservation.Particularly in recent years, domesticly started the whole grinding agitation of one cement half, on the basis of cement Joint grinding system, cement grinding system realize again amplitude larger carry product, grinding pow consumption reduces again.
Bed of material grinding device is compared with ball mill, have the weakness that is fatal, no matter be roll squeezer or Vertical Mill, the stable type of operation is poorer than ball mill, affect larger by material, the bed of material, pressure etc., when material feeding is uneven or feeding granularity, moisture content etc. are improper, bed of material grinding device can vibrate, the stability of influential system, system stop jumping is caused time serious, also damaging influence is produced to equipment itself, not only affects the normal production of cement, also reduce the service life of bed-grinding device.
Along with the development of bed of material grinding technology, the cement combination grinding that bed of material milling equipment and ball mill form or half final grinding system, output is improving constantly, grinding pow consumption is in continuous reduction, particularly developed popular cement half final grinding system in recent years, the basis of protocorm grinding machine realizes about 2 times put forward product effect, grinding pow consumption is down to below 27kWh/t.Realize so significantly carrying and produce and consumption reduction, system stable operation is very important, and particularly the stable operation of bed of material milling equipment is more important.What current cement half final grinding system application was more is roll squeezer half final grinding system, in order to ensure the stable operation of roll squeezer, current stabilization storehouse is designed with above roll squeezer, the material ensureing to enter roll squeezer realizes even feeding, realized by the position in storehouse in current stabilization storehouse, but when there is fluctuation in proportioning station supplied materials, the powder granularity going out roll squeezer can change, aidr bells blast system also has little time adjustment, the circulating load of roller press grinding system changes, thus cause current stabilization position in storehouse to be lost control of, roll squeezer throughput changes thereupon, thus cause roll squeezer generation fluctuation even to be vibrated.
In addition, in cement half final grinding system, powder after bed of material grinding is after V-type powder concentrator, meticulous powder concentrator select powder, the fine powder selected of meticulous powder concentrator is finished cement, meal or middle meal directly feed ball mill, generally directly connect ball mill bistrique spout by blanking scraper-trough conveyer or skewed slot.Significantly carry product along with Ball Mill System, ball mill milling capacity realizes maximizing substantially, once ball mill feeding fluctuates, no matter be open system or closed-circuit system, the grinding situation in ball mill all fluctuates; When ball mill is open system, when feeding granularity is thicker or feeding quantitative change is large, the cement fineness ground can run slightly, thus affects the performance of cement; When ball mill is closed-circuit system, when feeding granularity is thicker or feeding quantitative change is large, circulating load can be caused to change, and then powder system is selected in impact, causes cement granularity to change with grinding efficiency respectively, also can affect cement performance.
It is the key realizing half final grinding system high yield low energy consumption that the feeding capacity of visible control roll press and ball mill is stablized.Also there is same problem in Vertical Mill half final grinding system, what in Vertical Mill feeding capacity, thickness of feed layer and mill, raw meal particle size formed stablizes, and plays key effect to the stable operation of Vertical Mill.Only have former and later two grindings of system to equip and achieve stable operation, system could realize efficient grinding with energy-saving and cost-reducing.In order to stablize the charging of two grinding equipments, carrying out quantitative current stabilization feeding is critical technical measures.
