Description

The broken product line device of a kind of enclosed wind band material formula aluminium oxide crust piece
Technical field
The present invention relates to a kind of broken product line device, particularly relate to the broken product line device of a kind of enclosed wind band material formula 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 research and development present situation of domestic crushing process to aluminium oxide crust piece only is confined to individual equipment is is wherein rectified and improved and improved, as at present very many for the research of equipment such as grinding machine, grader, deduster, but the mutual coupling of integral device and individual equipment is not done further research.Information according to the announcement of association of China Non-Ferrous Metals Industry, have 12% to be 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 process of the comprehensive recycling of aluminium oxide crust piece, two kinds of technology modes of general employing: 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 by belt then material is carried out classification, be delivered to finished bin by conveying equipment afterwards.But equipment failure rate height in this technology, maintenance cost is big, and the disintegrating apparatus liner plate is not wear-resisting, thereby operation rate is reduced.And 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 it but exists, 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 Raymond mill self wearing and tearing also serious; 2, when the water content of aluminium oxide crust piece is big, in Raymond mill, adhere to easily, also in the blanking course of conveying, 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, before aluminium oxide crust piece abrasive dust, being doped with fine powder, 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, the structure of Raymond mill self, 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.
