Material Automatic Feeding System
The conveying of the materials is the key to the automation of the
compounding and feeding system. In the PVC automatic compounding
system, the conveying system occupies a large proportion:Including
the conveying from the bagging station to the transition silo upon
the batching scales,the finished materials conveying from the mixer
to the finished silo ,and also the finished materials conveying
from the finished silo to the extruder.
There are two main forms of application here: spiral conveying and
The spiral conveying equipment composed with motor, reducer and the
spiral. It has easy structure,work stable,but higher cost when the
distance is long.
The vacuum conveying system is a kind of conveying equipment for
conveying granule and powdery materials by vacuum suction. It is
widely used in the fields of pharmaceutical, food, chemical,
ceramics, feed, pigment, dye, agricultural products’ production and
scientific research. The use of vacuum conveyors can reduce dust
pollution in the workshop greatly, improve cleanliness, improve
production capacity significantly, and save a lot of labor, reduce
pollution, safe and reliable.
THE POWDER VACUUM SUCTION MACHINE HAS SUCH ADVANTAGES:
When harmful materials are not allowed to leak into the production
line; when the material is sensitive to transport and can not be
affected by the external impact, this is when you choose vacuum
powder suction machine.
The entire transport process is done in a closed system without any
powder leakage and contamination of the material. So that operators
do not have to bear the physical handling, and enjoy a low noise of
the working environment.
Vacuum conveyor is a pipeline closed transport, this transport can
prevent dust pollution, improve the working environment, while
reducing the environment and personnel pollution on the materials,
improve cleanliness; because it is pipeline transportation, it
takes smaller space, to complete the powder materials’ delivery in
a small and narrow space, so that the studio space will be
beautiful and generous; especially not restricted by the long or
short distance.At the same time, the vacuum feeder can reduce the
labor intensity, improve work efficiency,which all make it as the
first choice for most of the powder materials’delivery.
THE PRINCIPLE OF THE VACUUM CONVEYOR FOR POWDER:
It can produce high vacuum by the compressed air through the vacuum
generator,to convey the materials. It has a simpler structure,
smaller size, maintenance-free, low noise, easy to control,
eliminating the materials’ static and meet the GMP requirements and
etc. The high vacuum from the vacuum generator can avoid the
stratification,to ensure the uniformity of the mixed materials. It
is the preferred choice of extruder,mixer,packaging
machines,crushers,vibrating sieve and others’ automatic feeding.
When the compressed air supply to the vacuum generator, the vacuum
generator will produce negative pressure to form a vacuum flow, the
material is sucked into the suction nozzle, enter the hopper of
feeder through the suction tube by the flow. The filter will
completely separate the material from the air. When the material is
filled with the hopper, the controller will automatically cut off
the air supply, the vacuum generator will stop working, and the
material will open automatically and the materials will fall into
the hopper of the equipment. At the same time, the filter is
automatically cleaned by the compressed air from the pulse
back-flush valve. When the time or the level sensor reached,the
vacuum conveyor will be automatically activated.
