Description
Technical field
The invention belongs to mining equiment and resource recovery technology field, a kind of adhesive tape row series of rocks online dry-dressing machine of uniting particularly is provided.It is in short supply in current mineral resources to be used for solution, and ore deposit rock complicated condition depends on large-scale (10m
3, 16.8m
3) adopt under the situation that installing is difficult to fully to realize that the ore deposit rock separates effective recovery of ore in the row's of realization series of rocks system.
Background technology
Use ore reclaimer in the domestic bargh, currently be mainly used in, hour row's rock amount is little; The highest per hour treating capacity of production operation is about 400～500t; Thickness of feed layer is thin, and belt speed is slow, belt adopts on the basis of line belt, realizes the recovery of nugget.But reach 5400t/h for the belt maximum instantaneous through amount, thickness of feed layer reaches between 500～600mm, and granularity is at 0～350MM; Belt speed is fast; Under the conditions such as belt employing pierce tap, realize being mingled with in the rock recovery of ore do not have mature technique at present both at home and abroad.Sneak into the nugget in the rock according to the related data statistics; To reach about 6% of ore deposit rock total amount, under the situation that the international iron ore of present domestic iron ore deposit shortage significantly appreciates, this obviously is a considerable wealth; It is fully reclaimed, all significant in country in enterprise.
In sum; Water factory's iron ore works out row's series of rocks online dry-dressing machine of uniting; Utilize automation, information-based means to control, realized under the situation of belt system high strength, high-speed transportation, realize that the ore deposit rock in the material separates; Reach the purpose of mineral resource recovery, created considerable value.
Summary of the invention
The object of the present invention is to provide a kind of adhesive tape row series of rocks online dry-dressing machine of uniting; Be used for the recovery once more of the mineral resources that the row's of solution rock technical process runs off; Solved and only leaned on mechanical stripping to be difficult to realize whole separation in rock ore deposit; Make a small amount of ore sneak into rock, be transported to the refuse dump, cause the waste of resource through belt system.
According to stroke analysis, the ore resources that enters Tu Chang every year will reach about 6% of row's rock total amount, arrange rock total amount 5,000 ten thousand t per year and calculate, and will reclaim ore and reach 3,000,000 t, effectively avoid the waste of resource, create huge value wealth for enterprise simultaneously.
