Description
Technical field
The invention belongs to Chemical Engineering and Technology technical fields, especially relate to one kind and producing her by illite clay mine
The technological process of sharp mountain flour.
Background technology
Illite has the characteristics that smooth, bright, soft, good insulating, heat-resisting and hiding rare are high, is widely used in making
The industrial circles such as paper, plastics, rubber, paint, cosmetics, cable insulation, ceramics.The mines such as potassium, aluminium are also rich in illite
Substance, chemical process is carried out to it can produce the industrial products such as potash fertilizer, activated alumina and active silica flour.Again because of illite
Powder diameter is small, large specific surface area, has distinctive once bond structure, can be used as the adsorbent of low cost, and it is dirty to be applied to cyanobacteria, core
The environmental areas such as dye, industrial wastewater.
Illite is mainly present in nature in the form of two kinds, and one is hard ores, are mainly distributed on south such as Zhejiang
The provinces such as river, Henan, Hebei and the Northwest Shaanxi, and the production technology for having formed comparative maturity is as shown in Figure 1.Another kind is glutinous
Tu Kuang is mainly distributed on the areas such as Jiangxi, Jilin, Liaoning, the Inner Mongol.Due to Crack cause etc., the illite of clay mine form
Content is relatively fewer, and exploitation is later, in addition the reason of technology etc., the general production technology for using Fig. 1, Ye You producers according to
The actual conditions such as fund, technology and product demand use the production technology of Fig. 2 or Fig. 3, and the mode of production the simplest is Fig. 3
The production technology of stirring to pulp powder and most original.
The technical process of Fig. 1 is：Mine soil transports to Zhi Fen factories from mine, and being first crushed to mine soil (also has straight in mine
Connect broken), it is fitted into ball mill and carries out ball mill crushing, the slurry after ball milling, which enters in machine for cutting charge into pieces, further to be crushed, and is reached
Certain particle size.Pickling is carried out after delaminating again to remove Fe therein2+、Fe3+, enter back into centrifuge and centrifuge, remove big portion
Divide moisture, the slurry of removing part water is pumped into flame filter press, and after plate-frame filtering, illite slurry becomes water content 25%
~30% filter cake can be packed directly if making wet feed material uses such as papermaking and become product.Filter cake is dry by drier
It is dry, illite dry powder is can get, then packaged as the lower illite power-product of moisture content.
This technics comparing tradition, Technical comparing is ripe, has been run for many years in Small and Medium Enterprises in China.No matter mine soil material content
How, less with ore or mine soil is considered, through this process, it can finally obtain miberal powder.This production process is the disadvantage is that set
Standby abrasion is high, high energy consumption, and more important is powder compositions to change with the variation that ore raw materials forms, therefore in practical powder
In addition to illite, also other inorganic matters such as silicate, carbonate, sulfate, some places also have the organic matter of lower content.
Therefore, it is influenced by composition, this illite powder can only do the raw material of some low-end products, and productivity effect is not high.
Technical process as shown in Figure 2 is relatively above-mentioned more simple for process, and process is：Clay mine transports to weathering field
Ground is usually removed with excavator first through primary breakup, and larger clay block is separated into fritter, the day through mill house
It shines, wind, moisture loss, especially mine soil block surface will reach dry and comfortable, then reach certain size through destroying, then this mine soil
It is packed into dry in drier.Material is re-fed into pulverizer and crushes after drying, directly obtains illite dry powder.
For this technical process with respect to ball mill grinding, the equipment used is few, and technique seems simpler, and operability is strong.But this work
There are more problems for skill, first, the higher illite powder of purity cannot be obtained.It is all to enter crushing when machine crushes
The mine soil of machine can not all select pulverized, and it is difficult to meet some higher productions of purity requirement to lead to the illite powder produced
The needs of product.Second is that weathering or air-dried place can be very big in technique.Moisture is extremely difficult in illite clay mine scatters and disappears, and mine soil block is got over
Greatly, air-dry time is longer, there may come a time when that the several months can be reached.In order to accelerate the air-dried speed of clay mine, clay nugget must be reduced
Size, there is presently no the processing of very good method.In addition, drying equipment drying is chilled clay nugget, soil block
Size influences the size and operating parameter of drying equipment, mine soil block be difficult make size very uniform, once have internal undried
Clay mine enters in pulverizer, and dead pulverizer can be pasted in crushing process, it is made to be not normally functioning, once there is this in production
Kind situation, unique method of solution is exactly to dismantle pulverizer, is manually cleared up, and makes production can not possibly continuous operation.Moreover, dry
Dry clay nugget energy consumption is very big, and production is discontinuous, is bound to cause productivity effect low, or even loss.
In technique as shown in Figure 3, clay mine from mine transport to mineral powder plant through primary breakup be directly sent to level-one stirring beat
In stock tank, big lump ore soil becomes fritter by sluicing, two level stirred tank is fallen by macropore strainer under agitating paddle effect
In, online part is cleared out every now and then, relatively a little bit smaller mine soil block of head in two level stirred tank is fallen into, in agitating paddle
Under effect, by sluicing, tiny illite particle becomes slurries with water by strainer, then filtered through flame filter press,
It is dry, obtain illite dry powder.The online material of two level stirring to pulp is also timed cleaning, in technique I and II stirring continue absolutely
It is continuous, complete mashing production process.
This technique is original washing pulping process, and only manual operations changes machine stirring into.Device structure is relatively easy,
A certain amount of illite powder can be made.It is more at deficiency in technique.First, material will also carry out primary broken before level-one stirring
Broken, the clay mine for not so crossing a fat person is attached in stirring to pulp machine, and machine band does not get up, burnt out when serious motor or knob partially, folding
Disconnected agitating paddle, production can not carry out again.Second, with the presence of stone, agitating paddle blade serious wear, sometimes less than one in clay mine
A month, originally very thick, very strong paddle mill was not.The block material on third filter screen top is washed away not totally, is had sometimes
5-10% Erie's granite-wash is not got off, and the wastage of material of powder processed is caused.4th, the particle size range of illite powder is larger, impurity ratio
More, especially the tiny silicate of particle, product purity be not high.
Have using precedent in the production of three of the above technical process, respectively there are Positive and Negative Aspects, maximum disadvantage is that product purity is asked
Topic.In view of the shortcomings of the prior art, consider the feature of existing mine soil, exploitation more reasonable process, the efficient production equipment of design, it has also become
Using it is illitic there is an urgent need to.
Therefore there is an urgent need for a kind of novel technical solutions to solve the problems, such as this in the prior art.
