The liner vibrating
screen application is relatively universal and the advantages are also
obvious. It is able to improve fine ore grade, which is usually 1.0%-2.5%, or
the best even 4%-5%. It obtains a better effect in wear resistant. When
operation, liner vibrating screen will screen out finished product at first, and
then it grinds the left products with disqualification particle size. This
process allocation is rational and less investment. Besides, it obtains better
effect and earlier benefits.
Is fine iron ore better with higher fine ore
grade? As for the question, many people hold opposite opinions. Everything has
its limit, it will be bound to increasing equipment reformation investment if
we want to improve iron ore grade endlessly. Consequently, cost will increase
and recycling rate will reduce. Screening operation will influence water content
of fine iron ore, which is rather obvious when it combines with operation
and brings profound negative factors. Moreover, if fine ore grade improves too
large, the required good materials content used in BF iron making will loss and
reduce greatly, it will lead to instability of fine ore property, large wear of
equipments and large production cost. Therefore, we should not pursuit blindly
the higher fine iron ore grade. It is mainly decided by ore property and users'
requirements.
The particle size entering into liner vibrating screen is key
factor affecting screening effect. The more products which is up to the standard
particle size in materials, the higher screening rate. And the amount of
standard products depends on first stage ore grinding effect. Sometimes,
overflow products enters into liner vibrating screen, there many reasons for
that. The main reason is that the amount of ore in fist stage grinding changes,
or it may be workers' mishandle. When overflow products enters into liner
vibrating screen, operation efficiency and fine ore grade will reduced greatly.
Therefore, the operators should pay more attention to it and avoid such
accidents happening.
If you need to separate liquids from a solid compound
then a sieve bed screen would be the best investment. These are commonly found
in processing plants such as those that produce sugar, as well as in cement
mixing plants, mineral reclamation, and water treatment companies. If you are
involved with the disposal or treatment of industrial waste then the screens
would reduce the amount of burden that is place on the actual clarifier.
If the materials that are to be guarded are light then the vibrating screen
used can be manufactured out of a less heavy material, for example looped wire.
Another option is chrome plates or ceramic plates. Both are known for their long
life and versatility, they do not wear down as fast as some of the other
designs.
