The phosphorite complete production line

The mining of phosphate rock first jaw crusher preliminary broken, broken to a reasonable degree of fineness through the hoist to the mining machine into the ball mill ball mill crushing, grinding the ore. After the ball mill grinding the ore fines into the next process: classification. Spiral classifier With the different proportion of the solid particles and the speed of the principle of precipitation in the liquid ore mixture, washed and graded.

After a magnetic separator, washed and graded mineral mixture, due to the different variety of minerals than the susceptibility through magnetic force and mechanical force the mixture of magnetic material separated to. Separated from the minerals and other substances into the flotation machine, adding different drugs depending on the mineral characteristics, making the magnetic separator after the preliminary separation of mineral particles. Minerals to be separated, because they contain large amounts of water, subject to the initial enrichment of the concentrator, and then the dryer to dry mineral.

Crusher for phosphate mining

Election phosphorus broken machinery more categories, according to the crushing method, the mechanical construction characteristics (action principle) can be roughly divided into four categories:

1. The jaw crusher is this broken equipment, small phosphate applications, jaw crusher by movable jaw plate cycle pressure to the fixed jaw plate, the folder in which material crushed. The two jaw plates are rectangular, the existing jaw crusher jaw plate swing form can be divided into simple swing and swing of the two types.

2. The cone crusher ore in between inside and outside the two cone. Outside the cone fixed, tapered eccentric rotation of the pendulum movement, so the folder in which the ore is crushed or broken. A kind of crusher, cone crusher with acute steep cone roller broken cone crusher and cone tilt more gentle in the debris and crushing with the movable cone and fixed cone can be divided into.

3. The roll crusher, also known as roller machine, falls into this category is divided into a smooth roll face of the roller machine and gear Tong roll face of the roller machine. The ore is mainly affected by two opposite rotating circular roller caught in the continuous crushed role, but also with the role of grinding stripping, toothed roller surface there hack broken effect.

4. The impact crusher ore crushed by the shock of the rapid rotation of the moving parts. A kind of crusher cage crushers, compactors, and counterattack crusher.

mobile phosphate crushing plant

The eccentric shaft of a turn each half cycle for the broken, half-cycle for the row of ore. This makes it half the time the motor is idling, that is, the motor load is not balanced.

This has a flywheel to this part of the energy savings should be used broken. General after the design strength of the bracket is lower, when the chunk of ore falling into the crushing chamber, after the bracket by a sudden force is automatically broken, to avoid the movable jaw plate, connecting rod, eccentric shaft and the base of these important components are damage. The lining of the jaw plate directly in contact with the ore, easy to wear, the general use of manganese steel manufacturing, and the board appear before the dentate to the crushing force.

Phosphate mill processing of phosphate rock

Ore mining, ore block, the largest particle size is generally about 500 mm. Phosphate material disseminated fine-grained, and closely integrated with symbiotic minerals and gangue. So before sorting, the ore must be approved by the crushing and grinding, so that full dissociation of phosphate rock materials. Crushing and grinding to achieve particle size mainly depends on the dip of the phosphate material grain size and mineral processing methods used in, and phosphate are generally flotation.

Crystalline apatite disseminated particle size is generally 0.5 - 0.1 mm, the finer granularity of glial phosphate dip, generally less than O.1 mm. Disseminated more fine particle size, grinding offerings degree should be more fine, or phosphorus minerals and gangue minerals can not be achieved the separation of the monomer, a direct impact on the quality of the selected points. Therefore, crushing, grinding the ore separation were to be prepared job.

Production practice is not broken ore survived fine as possible. Because, first, ore crushing survived fine, the greater power consumption and the wear on the increase in processing costs. Second, ore crushing too much detail, it is bound to generate a lot of fine mud, resulting in over crushed fine mud to influence the election process, to reduce the effect of selected points. The selected points must be the right decision broken particle size, making it technically and economically reasonable.

Around the early mining gneiss siliceous apatite ore, basically on the surface regolith, mined ore is relatively soft, the grain size is generally small, and some mining areas are not even directly after breaking into the grinding or before grinding into the sieve, sieve out large pieces of artificial broken, and then given away the mill.

Due to the limitations of current technology and economic conditions, not chunks of ore from the mining in a direct fragmentation to the granularity of the selected points required before, so crushing (or grinding) is carried out in stages.
