In order to separate the useful minerals and gangue minerals, we should
first crush phosphate rock, so that the phosphate material is in monomer
separation state, which is called "single separation degree". Only in the
dissociation case can we select phosphate material. Therefore, usually the ore
should first experience crushing and grinding operation before concentration
operation. Finally, the finished product is higher phosphorus which is called
the phosphate concentrate.
Now that the concentrate is elected, the
remaining products, including the low content of phosphate compounds, is usually
called tailings. In this process, we sometimes separate a part of semi-finished
products, which needs further processing is called middling mine. The phosphate
concentrate produced by
contains large amounts of water, so it needs dehydration and drying for use and
transportation.
Generally, the entire dressing process usually
includes crushing, grinding, ore concentration and product
dehydration.
The purpose of the recovery processing is recycling
phosphorus ore minerals to maximum extend. The completion of this election
process is measured by the weight proportion of phosphorus pentoxide of
concentrates in that of original ore.
According to the difficulty degree in crushing, ore can be divided
into three types: hard ore, middle hard ore and soft ore. Most of the Phosphate
ore belong to the middle hard ore. According to different ore natures, we need
to adopt different designs of crusher machies.
BF type draws on the advantages of similar products at home and abroad.
The advanced technology, national invention paten self- priming slurry, is
used in BF type flotation machine. As for the features of fine iron ore
anti-flotation processing flow, we specially developed the high efficiency
separation equipment. This machine consists of motor, spindle, bearing the body,
the center tube, steady flow plate, impeller, cover and suction pipe, diversion
pipe, false bottom, tank and other components. The features of BF type flotation
machine: biconical disk closed impeller flotation machine with tilting blade,
cone disc stator with a forward blades, the impeller and the stator to match
constitutes a unique impeller subsystem of the BF type flotation machine. The
aircraft has the air of self-absorption, self-priming slurry and the triple
function of flotation, flotation operations between the horizontal
configuration, without auxiliary equipment, process configuration is simple,
flexible changes.Work principle of BF type flotation machine: When the spindle
motor-driven rotating impeller cavity pulp by the action of centrifugal force to
four weeks thrown, so that the impeller cavity to produce the negative pressure
by giving mine to mine, mine, and air, respectively tube in mine management and
suction suction to the separated plate above.
