Description
Technical field
The utility model belongs to fine aluminum hydroxide powder production unit field, is specifically related to a kind of production system of low viscosity fine particle fine aluminum hydroxide powder.
Background technology
Ball-grinding machine has employed upper a century as the most frequently used grinding plant, for a kind of simple and reliable and durable grinding plant is widely used in the various product of grinding.But aluminium hydroxide Mohs' hardness is 3,3 existence hydroxy make its chemical polarity stronger, use during general ball mill grinding and occur a large amount of slimeballs and sticky mill phenomenon, and occur that a large amount of aluminium hydroxide sheets is reunited, finished product cannot use, and these aluminium hydroxide sheets are reunited and system also can be caused normally not run, simultaneously production of aluminum hydroxide equipment is Raymond mill, impact grinding or airflow milling all exist the aluminum hydroxide product crystal formation after fragmentation by serious brokenization, grain thickness is uneven, the shortcomings such as size-grade distribution is wide, and oil-absorption(number) is high.
Summary of the invention
For problems of the prior art, the utility model provides a kind of production system of low viscosity fine particle fine aluminum hydroxide powder, effectively can remove aluminium hydroxide sheet and reunite, hydroxide particle-size be distributed more concentrated, can expand the scale of production simultaneously, realize automatic management.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A production system for low viscosity fine particle fine aluminum hydroxide powder, comprises raw material cabin, and described raw material cabin is connected with continuous ball mill, continuous ball mill is connected with vibratory screening apparatus, vibratory screening apparatus is connected with grading machine, and grading machine is connected with continuous ball mill, and grading machine is connected with packaging facilities.
Described continuous ball mill is continuous tumbling ball mill or continuous vibration ball mill.
The pipeline that described vibratory screening apparatus is connected with grading machine is provided with blower fan.
Transport unit is provided with between described grading machine and continuous ball mill.
The beneficial effects of the utility model: the production system of low viscosity fine particle fine aluminum hydroxide powder of the present utility model, fine aluminum hydroxide powder makes work in-process after continuous ball mill, remove aluminium hydroxide sheet through vibratory screening apparatus to reunite, then packet assembler is entered at the fine aluminum hydroxide powder selecting particle diameter under powder effect to reach design requirements of grading machine, under the effect of transport unit, continuous ball mill is reentered after the underproof free setting of particle diameter, continuous circulation, large scale continuous prod can be realized, convenient management, the fine aluminum hydroxide powder finished product grain size distribution obtained is concentrated, meet the demand of different performance product, and aluminum oxide sheet is reunited and can effectively be removed, the normal operation of guarantee system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of production system of low viscosity fine particle fine aluminum hydroxide powder, comprise raw material cabin 1, described raw material cabin 1 is connected with continuous tumbling ball mill 6, and continuous tumbling ball mill 6 is connected with vibratory screening apparatus 5, and vibratory screening apparatus 5 is connected with grading machine 2, the pipeline that vibratory screening apparatus 5 is connected with grading machine 2 is provided with blower fan 4, grading machine 2 is connected with continuous tumbling ball mill 6, and be provided with transport unit 7 between grading machine 2 and continuous tumbling ball mill 6, grading machine 2 is connected with packaging facilities 3.
The working process of this system is as follows: the fine aluminum hydroxide powder of raw material cabin uses continuous tumbling ball mill that aluminium hydroxide is processed into work in-process, the work in-process aluminium hydroxide processed removes macrobead by vibratory screening apparatus and aluminium hydroxide sheet is reunited, then grading machine is entered by blower fan, through the screening of grading machine, qualified fine aluminum hydroxide powder enters packet assembler, underproof fine aluminum hydroxide powder again returns into continuous tumbling ball mill under the effect of transport unit, cyclic production.
Embodiment 2
With the continuous tumbling ball mill in continuous vibration ball mill alternative embodiment 1 in the present embodiment, other embodiments are with embodiment 1.
Aluminium hydroxide raw material is mainly divided into sintering process aluminium hydroxide and two kinds, Bayer process aluminium hydroxide, wherein sintering process aluminium hydroxide raw material is better, but market value per ton will exceed 900 yuan than Bayer process aluminium hydroxide raw material, if the Bayer process fine aluminum hydroxide powder oil-absorption(number) of the explained hereafter before using reaches 38, client cannot use, and only draws high price and uses sintering process fine aluminum hydroxide powder product.Following table is the fine aluminum hydroxide powder oil-absorption(number) contrast table that the production system of the utility model low viscosity fine particle fine aluminum hydroxide powder and common production system prepare.
| Kind | Oil-absorption(number) |
| The low viscosity aluminium hydroxide that the continuous round as a ball ball mill of embodiment 1 is produced | 29 |
| The modification low viscosity aluminium hydroxide that embodiment 2 continuous shaking ball mill is produced | 21 |
| Domestic Bayer process fine aluminum hydroxide powder, specification 10 | 38 |
| Domestic sintering process fine aluminum hydroxide powder, specification 10 | 32 |
The fine aluminum hydroxide powder oil-absorption(number) being used Bayer process aluminium hydroxide raw material production by native system is 29, and reach the service requirements of client, raw materials cost achieves and declines to a great extent.Continuous shaking ball mill is utilized to produce a large amount of heat energy (internal temperature of vibromill can reach 60 DEG C) in grinding aluminium hydroxide process, by add stearic acid surface properties-correcting agent in continuous shaking ball milling with aluminium hydroxide co-ground, the grinding, the modification that reach aluminium hydroxide together complete, realize Modified by Aluminum Hydroxide minimization of cost, the fine aluminum hydroxide powder oil-absorption(number) of modification significantly reduces further, reaches 21.
