Feldspar powder purification equipment is the use of feldspar powder, the main mineral is diamagnetic material feldspar powder, in the magnetic field can not be magnetized. In the feldspar powder, iron containing impurity minerals: hematite, limonite, magnetite, goethite and so on, are all magnetic materials, which can be magnetized in the magnetic field. In the magnetic process is the use of this difference in nature, so the magnetic separation of minerals and magnetic minerals, through the separation of feldspar in the removal of iron impurities.
Crushing: Use the Jaw crusher to crush the material stone.
Ball milling: mill the stone after crushed in the ball milling.
Slurry washing: delivery the 20-200 mesh powder into the spiral chute, classify and separate the sand from the slurry.
Classifying: Delivery the separated slurry into the vibrating sieve, to separate the ferric oxide.
Iron separating: Removing ferric oxide material into 1024 type strong magnetic re-election machine selection, select iron, mica material, and material into 1018 * 2 type general magnetic separator, the separation again; Attention: at present, the use of magnetic separator to remove iron from potash feldspar is not suitable for all potash feldspar mines, and flotation process has been widely used.
Purification: After re-election and the general election materials to the high frequency vibration screen, eliminating powder in Fe2O3 and Fe3O4, from potassium feldspar powder;
Screening potassium feldspar powder: The fine powder of potash feldspar was sent into 20-200 mesh sieve, and the screened product was the finished product with iron content below 0.24%.
Characteristics of feldspar dry powder iron removal equipment
Using high intensity magnetic separator, the magnetic induction intensity can be up to 25000Gs
Compact structure, according to the process of mineral processing design multi section magnetic separation series (parallel) as one of the models, reduce facilities and save space
For the belt models according to different design requirements of processing, can effectively achieve the alternative material containing a small amount (less than 2%) smoothly discharging fine strong magnetic minerals and iron.
Processing equipment used in the production line to the potassium feldspar: crushing equipment, vibration sieve, transportation equipment, silos, feeding equipment, grinding equipment, grading equipment, magnetic separation equipment, heavy equipment, filter, spiral chute and other auxiliary equipment.
