Rutile itself is necessary raw materials of high-grade welding, is
one of the best raw materials for the production of rutile titanium
dioxide. Mined rutile ore after deep processing of high-pressure
mill and crushing, grinding equipment, become titanium dioxide.
A full set of rutile mineral processing equipment include crusher,
ball mill, classifier, magnetic separator, flotation machine,
dryer, feeder, elevator.The common rutile broken equipment adopts
the impact crusher. The impact crusher is apply to the crushing of
hard materials, such as cement plant limestone crusher.
Impact crusher works:stone directly from the machine upper part fall into the high-speed
rotation of the turntable; Under the effect of high-speed
centrifugal force, high-speed collision, high-density crushing,
with another part of the flying stone that shunt in dial around by
the way of umbrella, stone fight against each other, which will
form vortex movement between the dial and case so that cause many
times fight against each other, friction, grinding, direct
discharge from the lower part. Form a several times closed loop to
reach the required particle size by sieving device control.
Rutile ore beneficiaton
Rutile dressing method include the mechanical re-election (washing,
screening, high intensity magnetic separation and flotation
separation) and fire enrichment, chemical processing method.
1. Rutile washing and screening
Washing is the use of hydraulic flushing or additional mechanical
scrubbing for the separation of ore and shale. Commonly used
equipment are washing griddle, cylinder washing machine and
trough-type washing machine.
Washing operations often is associated with screening. Screening
can be as an independent operation, the separation of different
particle size and grade of product to supply for different uses.
2. Rutile re-election
Re-election only is used for sorting simple structure, embedded in
the cloth, coarse grain size of rutile stone, especially for oxide
rutile at high density. Common methods are heavy media
beneficiation , jig beneficiation and shaker beneficiation.
3. Rutile high intensity magnetic separation
Rutile crystal belongs to the weakly magnetic minerals . Sorting
magnetic separation operation is simple and easy to control, high
adaptability, and can be used for a variety of rutile dressing, in
recent years has been dominated in the rutile ore dressing. New
types of coarse, medium and fine-grained magnetic machine has been
developed successfully. At present, the most common domestic rutile
is medium-grained strong magnetic separator, coarse and fine strong
magnetic separator has gradually been applied , while micro-fine
strong magnetic separator is still at an experimental stage.
