Abstract
The invention relates to a production method of a red mud filler, which comprises the steps of firstly using a plate and frame filter press for reducing the water content in red mud to below 30%; further sending into a flash dryer for processing, and obtaining red mud powder material with 325-5000 meshes; and utilizing a cyclone separator for grading the red mud powder material with 325-5000 meshes: five grades of 325 meshes, 800 meshes, 1250 meshes, 2500 meshes and 5000 meshes. The five grades can be selected and used by users. The production method has the advantages that the production method changes the clumsy method of firstly drying and further utilizing a ball mill for processing repeatedly for complicated coarsening in the past, and uses the flash dryer produced by Changzhou Maijieke Drying Equipment Co., Ltd for processing once for further obtaining fine particles with 325-2000 meshes, thereby realizing simple processing and finer grinding, expanding the range of applications, shortening the processing time, reducing the pollution and realizing low cost.
Description
Technical field
Involved in the present invention is the processing and treating method of waste Aluminum slag red mud, belongs to metallurgical industry waste ' s reclamation field.
Background technology
The production of China's aluminum oxide increases year by year, and its output jumps according to the second place of the world.Our province not only Zibo, Longkou has had large-scale aluminium manufacturer, and Chiping, Zou have also newly built up large-scale aluminium manufacturer coequally.Aluminium manufacturer smelts the back and discharges red waste residue, generally is called red mud, and pile up like a mountain for red mud, occupies cultivated land, contaminate environment, and water and air degenerates, and influences personnel safety, and for this reason, the utilization of red mud is the urgent hope of people always.Utilize red mud to extract iron, rare metal scandium, titanium etc. for many years, make the red mud brick again, red mud cement and make red mud plastic is produced hard tube, flexible pipe, plate, process hides or the like.But red mud mostly is sposh, and water content is about 70%, can not directly make stopping composition.The patent No. is 200810302093.8 and is called " method and apparatus that red mud for alumina plant is handled " patent, though utilize plate-and-frame filter press that the red mud water content is reduced, is piled into the mountain then, still can not be directly as stopping composition.Want ad hoc red mud pre-treatment plant: with the red mud dehydration, Tumble Dry again earlier, be milled to about the 80-300 order with ball mill again, make stopping composition.There is the cost height in this processing, and grinding particle size is thick, and utilization ratio is low.
Summary of the invention
The present invention finds out the preferred processing scheme of making filler with red mud for overcoming above-mentioned defective.
A kind of technological process of production that with the red mud is raw material is processed into filler is: red mud, and------it is standby that---cyclonic separator classification---pulverized in the flash dryer oven dry in the pressure filter dehydration.
Concrete production method is as follows: with plate-and-frame filter press the red mud water content is reduced to below 30% earlier; Send into the expansion drying machining again, obtain 325---5000 hot eyes mud powders; Utilizing cyclonic separator with 325 again---5000 hot eyes mud powders are divided into 5 grades, select for use for the user.
Above-mentioned 5 grades of powders are meant: 325 orders, 800 orders, 250 orders, 1250 orders, 2500 orders.
Above-mentioned flash dryer is meant: the flash dryer that the outstanding objective drying plant of Changzhou wheat company limited produces.
Advantage of the present invention is: changed the oven dry earlier of numerous and diverse alligatoring in the past, use the clumsy method of more than times processing of ball mill again, and the flash dryer time processing of having used Changzhou wheat Czech drying plant company limited to produce can obtain 325-5000 order fine particle.Processing is simple, and pulverizing thinner enlarged range of application, shortened process period, reduces and pollutes, and cost is low.
Embodiment
The inventor sends out an aluminium metallurgy factory of aluminium electricity group at Chiping letter, and to do experiment successful: with plate-and-frame filter press the red soil raw material is dewatered to water content below 30% earlier, enter flash dryer (the outstanding objective drying plant of Changzhou wheat company limited produces) then, drying and grinding powdering under 400 ℃ of conditions in flash dryer, sub-elect the following particle of 1250 orders with cyclonic separator again, promptly can be used as the blowing stopping composition and use.Lab scale has been made qualified blown film.
