Product Overview:
GZL series of dry granulating machine is the roller pressure by
dry extrusion technology, the water content of <10% of the
powder compressed into tablets, through the broken Whole, the
screening process so that the bulk of the film material into line
with the requirements of the use of granular materials.
dry granulation roller pressure on the external pressure is the
main way through two materials mandatory rotation of roller round
of negative space, compressed into tablets. Roll pressure in the
process, the actual density of materials to increase 1.5-3 times to
meet certain requirements of the force. Features:
materials are mandatory compression molding machinery pressure, do
not add any wetting agent, the purity of the product is assured.
powder made material directly, without follow-up the drying process
will be more conducive to the convergence of existing production
processes and transformation.
high intensity particle accumulation other than increasing share of
granulation method is more significant. Especially for the increase
in the proportion of product accumulation of occasions.
can control environmental pollution, reduce waste and powder
packaging costs, improve product transport capacity.
compact structure, easy maintenance, simple operation, the process
short, low energy consumption, high efficiency and low failure
rate, suitable for a wide range of raw materials, pressure roller
to adjustment based on different materials.
feed and feed device using frequency stepless adjustment control, a
high degree of automation, a person can achieve multi-machine
control, low labour intensity, and the long-term continuous
operation, and other features.
main transmission quality components are used alloy, stainless
steel materials, Titanium, chromium and other surface alloy
production, greatly improving the wear resistance, corrosion
resistance, high temperature and pressure capabilities, the
aircraft has a longer life.
Principle:
various powder materials from the top by adding equipment, the
degassing, spiral surcharging equal access to the two rollers,
roller relative rotation, and materials are forced into between two
rollers, roll materials will bite into the roll gap compression ,
and materials through the compression zone, materials, surface
tension and gravity make it naturally emerge. Prolapse refers to
the strip into the mass of the rotating nibs Pai broken knife was
broken materials enter through the rolling machine knife Whole row
of the particle and powder materials into the rotation vibration
sieve screen. Qualified for and was sent by conveyor products
warehouse. Powdered materials through the sieve again be returned
to the conveyor secondary raw materials warehouse roller pressure,
squeezing pressure on the size of operation according to the needs
of granulation from the hydraulic pressure regulation.
by changing the roll surface grooving form can be patchy, strip,
Chen Shui-bian spherical materials.
Process:
I passed by feeding raw materials into the screw conveyor bucket
hoist by bucket elevator powder materials will be sent vibrating
raw materials warehouse, through quantitative materials will feed
into the machine screw Feeder frequency of the material pre -
compression, the pre-compressed material being pressed into two
relative of the two pairs of rotation among compaction roller
pressure, pressure through the strength of the thrust from the fuel
tank pressure roller to transfer materials, the film was compacted
bar Material from automatic slot into the crusher, will be broken
into its uneven size of the particles and then go to Whole machine
repaired. Are trimmed with the particles through the mesh sieve
plate was squeezed out into the screening machine, finished
particles through the screen and entered bucket elevator and was
sent to warehouse products. Screener down through the powder
returned to the screw conveyor of raw materials warehouse, which
completed a compaction again closed cycle.
