Description
Technical field
The utility model relates to broken product line device, especially a kind of closed circuit product line device of broken aluminium oxide crust piece.
Background technology
In recent years, the aluminum electrolysis industry development is added up demonstration since calendar year 2001 rapidly, and the demand of domestic electrolytic aluminium is with the speed increment in 1,000,000 tons of every year; By the end of the year 2003, the Aluminum Electrolysis Production ability reaches 8,340,000 tons; By 2008, the Aluminum Electrolysis Production ability reached 1,250 ten thousand tons.Along with the quick growth of China's electrolytic aluminium output, the aluminium oxide crust piece that aluminium electrolysis enterprise is left over aborning also increases thereupon.Yet the crushing process research and development present situation of domestic aluminium oxide crust piece only is confined to individual equipment is is wherein rectified and improved and improved; As at present very many, but the mutual coupling of integral device and individual equipment is not done further research for the research of equipment such as grinding machine, grader, deduster.Information according to the announcement of association of China Non-Ferrous Metals Industry; Have 12% to adopt the aluminium oxide crust piece treatment process that falls behind in the electrolytic aluminium production capacity of the whole nation approximately; At present; In the comprehensive recycling process of aluminium oxide crust piece, generally adopt two kinds of technology modes: a kind of is multiple stage crushing technology, and a kind of is the Raymond mill crushing process.
One, multiple stage crushing technology: adopt two stage crusher that material is carried out fragmentation, be delivered to vibratory sieve through belt then material is carried out classification, then be delivered to finished bin by conveying equipment.But equipment failure rate is high in this technology, and maintenance cost is big, and the disintegrating apparatus liner plate is not wear-resisting, thereby operation rate is reduced.The material airborne dust is bigger in the whole system running, and site environment can not reach environmental requirement, and the worker laboring environment is poor.
Two, Raymond mill crushing process: adopt Raymond mill that the aluminium oxide piece that crusts is worn into powder; Efficient is low, the problem of the bad control of material yet exist; Be mainly reflected in 1, when the hardness of aluminium oxide crust piece is high, the speed of Raymond mill abrasive dust is too slow, and self wearing and tearing of Raymond mill are also serious; When 2, the water content of aluminium oxide crust piece is big, in Raymond mill, adhere to easily, also in the blanking conveying process, stop up easily, cause Raymond mill production capacity to reduce; 3, when aluminium oxide crust piece fineness of grinding being required when high, then Raymond mill abrasive dust ability is little; When 4, being doped with fine powder before the aluminium oxide crust piece abrasive dust, need to cross in advance once sieve; Otherwise these fine powders adhere to the conveying that material is worn in influence easily in raymond mill; 5, Raymond mill self structure, the wearability of tup, Hubei Province plate has determined the abrasive dust ability of Raymond mill to a certain extent, therefore is difficult to adapt to big industrial expansion requirement.
According to the above; Because aluminium electrolysis enterprise generally adopts the treatment process of backward aluminium oxide crust piece; The big industrial factors of influence such as the said method working (machining) efficiency is low, equipment failure rate is high, automaticity is low, and plant maintenance and maintenance workload are big, labor strength is high and the potroom environment is damaged; The quantum of output that causes aluminium oxide crust piece is far above yield; Form a large amount of overstocking; Cause the maintenance cost of transportation and warehouse cost, broken processing cost and device therefor of aluminium oxide crust piece high, therefore be badly in need of a kind of crushing process of alumina crusting block and production line thereof that is applicable to big suitability for industrialized production.
