Description
Technical field
The present invention relates to potassium feldspar powder-making technique field, especially a kind of device for adjusting feldspar in powder size distribution.
Background technique
Potassium feldspar is a kind of nonmetallic ore containing elements such as potassium, sodium, silicon, aluminium, iron, and the feldspar in powder after processing is extensive
It is long to potassium with every profession and trade with the development of science and technology for industrial production raw materials such as ceramics, electroceramics, enamel, glass, welding rods
The requirement of mountain flour performance is continuously improved, the production of potassium feldspar fine and the cost effective inexorable trend for having become development.
The grinding of potassium feldspar is realized using ball mill, common to select powder technology for dry method ball mill is closed circuit,
It includes being connected by feed system, ball mill, lifting means, powder concentrator, finished product elevator and semi-finished product feed back conveying mechanism
Made of mill is outer selects powder system and as made of feed inlet of globe mill, inner cavity, discharge port, exhaust pipe, deduster, blower concatenation
Promote to grind the interior material air bypass system mobile to mill tail.Work of the interior material by grinding to certain particle size of mill in blower draft
Under, is driven constantly by air-flow to the outlet movement of mill tail, powder concentrator is delivered to by lifting means after drawing off, the finished product after separation
Powdery finished product repository, coarse grained semi-finished product and iron particle material is delivered to by finished product elevator to be conveyed by elevator and feed back
Mechanism is delivered to bistrique feeding bin, and newly plus material is synchronous into carrying out grinding again after ball mill；The fine powder that mill last row wind is taken away
Separation is trapped by the deduster in air bypass system, powder product repository, purified air are delivered to by lifting means
Atmosphere is discharged into through blower.In this way, the grinding phenomenon excessively of interior material can partly be avoided grinding, mitigate grinding load.In the above method,
The air quantity of blower is usually pre-set before producing, and the air quantity of blower immobilizes in production process, the potassium produced in this way
The particle size distribution of feldspar powder is wider, and granularity is not concentrated, and fine powder is on the high side, cannot be according to feldspar in powder granularity point in production process
The different technologies index of cloth is flexibly adjusted.Above-mentioned dry method ball mill is closed circuit to be selected in powder technology, feldspar in powder size distribution
Related with air quantity, air quantity is bigger, and the amount of fine powder is fewer in feldspar in powder；Air quantity is smaller, and the amount of fine powder is also more in feldspar in powder；
This is because: when air quantity is larger, the material of big granularity is blown out in time, so that the time of grinding is reduced, so that potassium feldspar
The amount of fine powder is reduced in powder, conversely, when air quantity is smaller, material is just blown out when being ground to smaller particle size, so that feldspar in powder
The amount of middle fine powder increases.
Application No. is a kind of device and method of adjusting feldspar in powder size distribution of CN201310460061.1, devices
Including the blast regulation system being located on the discharge port of ball mill, which includes feed bin, main air hose and lateral
Blast pipe；Wherein, the lateral middle part of the feed bin is connected on the discharge port of ball mill；One end of the main air hose is connected to material
The upper end in storehouse, the other end form the section of converging passed through below feed bin, the lower end connection of the feed bin after extending downwardly and bending
Converge in section at this；The side air admission pipe setting converges in section described, and is equipped with air quantity adjusting in the side air admission pipe and opens
It closes；The lower end of the feed bin and it is described converge between section be equipped with rotating blanking valve.The device and method of the invention can be according to potassium
The size distribution requirements of feldspar powder, in process of production in real time, neatly adjust side air admission manage-style amount, to adjust potassium feldspar
Powder Particle Size distribution, production chains greatly promote, and are easier to ensure that product quality.However, the device of the invention is by upper
Lower two channels make feldspar in powder be blown out or sink to dropping out naturally, and its structure is complicated, and it is easy that the star of use places blanking device
Blocking and cost height；The feldspar in powder for being accumulated in the larger granularity of feed bin is not easy to steam again into ball mill and grind again.
