High Fineness Unscreened Crushing Line product description
The high fineness non-screening crushing production line consists
of raw material silo, vibrating (screening) feeder, jaw crusher,
toothed roll crusher (cone crusher according to customer's
requirements), two roll crushers, suspended permanent magnetic iron
remover, several belt conveyors, dust collection system and
electric control system. It is characterized by no screening, low
running cost, no fear of moisture, large output, low power
consumption and less dust. It is a rare and mature high fineness
non-screening production line in today's domestic market.
It can be used for crushing all kinds of stones with compressive
strength less than 300Mpa, such as limestone, dolomite, river
pebbles, granite, basalt, quartzite, potassium feldspar and so on.
It is mainly used in building materials, coal water slurry, iron
and steel, thermoelectricity, chemical industry, etc., especially
when the material humidity is very large (viscous) can not be
screened occasions.
High Fineness Unscreened Crushing Line working principle
When the high fineness non-screening crushing production line is
working, turn on the electric control system according to the
sequential order, start all the equipments, use the loader to pour
the large stone into the raw material warehouse, then the vibrating
screen feeder (connected with the suspended permanent magnetic
separator at the material drop) will firstly send the stone (mixed
with clay) and so on into the jaw crusher by the belt conveyor for
coarse crushing, and the coarse crushing will be crushed to 120mm,
and then sent into the toothed-roll crusher for secondary crushing
(middle crushing) by the belt conveyor through the fabricator to
the 1# roller crusher for fine crushing to 8mm or so. Crusher for
secondary crushing (medium crushing), medium crushing to about
40mm, from the belt conveyor through the fabricator into the 1 #
roller crusher for fine crushing to about 8mm. And then by the belt
conveyor through the fabricator into the 2 # roller crusher for
fine crushing to about 2mm, without screening equipment, that is,
to achieve about 98% of the finished product rate.
If the silica content of the stone is too high, when the roll
surface is worn out faster, the roller surface grinding (cutting)
device is configured, and the roller surface is repaired with the
grinding device at any time according to the roller surface
condition, and the granularity requirement is guaranteed at all
times.
The capacity of high fineness non-screening crushing production
line can be designed according to the customer's requirements,
configured with different models of equipment, in the discharge
size of about 2mm non-screening, a single production line can reach
10-300t / h. The production line can be equipped with dust
collector according to the customer's requirements.
According to customer's requirement, this production line is
equipped with dust collector, i.e. the dust collector is added in
the feeding and discharging ports of jaw crusher, the feeding and
discharging ports of toothed roll crusher and the feeding and
discharging ports of the two roller crushers, and the high negative
pressure of the dust collector's fan is utilized to adsorb the
micro-fine particles on the bag, and the bag is automatically
vibrated and cleaned up regularly, so that the dust is collected
and meets the national environmental protection standard.
