Description
Technical field
The invention relates to a kind of crushing production line device, relate to especially a kind of product line device of crushing aluminum oxide crusting block.
Background technology
In recent years, rapidly, statistics shows since calendar year 2001 for aluminum electrolysis industry development, and the demand of domestic electrolytic aluminium is with the speed increment of annual 1000000 tons; By the end of the year 2003, Aluminum Electrolysis Production ability reaches 8,340,000 tons; By 2008, Aluminum Electrolysis Production ability reached 1,250 ten thousand tons.Along with the rapid growth of China's electrolytic aluminium output, the alumina crust block that aluminium electrolysis enterprise is left over aborning also increases thereupon.But the Current Status of R & D of the domestic crushing process to alumina crust block is only confined to individual equipment wherein rectify and improve and improve, as at present very many for the research of the equipment such as grinding machine, grader, deduster, but the mutual coupling of integral device and individual equipment is not made further research.The information of announcing according to association of China Non-Ferrous Metals Industry, in the electrolytic aluminium production capacity of the whole nation, approximately have 12% to be to adopt the alumina crust block treatment process falling behind, at present, in the process of the comprehensive recycling of alumina crust block, two kinds of technology modes of general employing: one is multiple stage crushing technique, and one is Raymond mill crushing process.
One, multiple stage crushing technique: adopt two stage crusher to carry out fragmentation to material, then by Belt Conveying to vibratory sieve, material is carried out to classification, be delivered to finished bin by conveying equipment afterwards.But in this technique, equipment failure rate is high, and maintenance cost is large, and disintegrating apparatus liner plate is not wear-resisting, thereby operation rate is reduced.And material airborne dust is larger in whole system running, site environment can not meet the requirement of environmental protection, and worker laboring environment is poor.
Two, Raymond mill crushing process: adopt Raymond mill that alumina crust block is worn into powder, but it but exists, efficiency is low, the problem of the bad control of material, be mainly reflected in 1, in the time that the hardness of alumina crust block is high, the speed of Raymond mill abrasive dust is too slow, and Raymond mill self wearing and tearing also serious; 2, in the time that the water content of alumina crust block is large, in Raymond mill, easily adhere to, also easily in blanking course of conveying, stop up, cause Raymond mill production capacity to reduce; 3, when alumina crust block fineness of grinding being required when high, Raymond mill abrasive dust ability is little; 4, before alumina crust block abrasive dust, during doped with fine powder, need cross in advance once sieve; Otherwise these fine powders easily adhere to the conveying that material is worn in impact 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, is therefore difficult to adapt to large industrial expansion requirement.
According to the above, because aluminium electrolysis enterprise generally adopts the treatment process of backward alumina crust block, the large industrial factors of impact such as the working (machining) efficiency of said method is low, equipment failure rate is high, automaticity is low, and plant maintenance and maintenance workload are large, labor strength is high and potroom environment is damaged; Cause the quantum of output of alumina crust block far above yield, form a large amount of overstocking, cause the transport of alumina crust block and the maintenance cost of warehouse cost, broken processing cost and device therefor high, be therefore badly in need of a kind of crushing process of alumina crusting block and production line thereof that is applicable to large suitability for industrialized production.
