Working principle: SE
series of screw type extruding pelleter include single-screw
type and double-screw-type. Two models of front and side
for material to be extruded out. Wet material or material
with low melting point (general means < 50¡æ) after
being kneaded and mixed shall be extruded out from mould
plate at the head of the plant due to being conveyed and
pressed by screws, and then be dried or cooled to form
end products of particles so as to complete the course
of changing material from powder to particle. The shape
of grain is cylindrical. The diameter of end grain can be
chosen
and controlled by means of changing the diameter of holes in
the mould plate: for side type is 0.7-2.0mm£¬for front type
is 1.5-12mm. The rate of end product is equal to or more
than 95%.

Applied
scope: The plant is widely applied
to material needs granulating such as Rubber auxiliar, Food
Additive, Plastic Auxiliary, Catalyzer, Agrochemicals, Dye, Pigment, daily
chemicals, medicine etc.
Main merits:
As the powder
material is kept in wet state during the whole
process of granulation, The working condition is greatly
promoted. Flying of dust is generally reduced to over
90% of that used to be.
Some phenomenon
that well influent application such as curdling, framing, pulsing
etc can be averted by means of granulation.
As the stacking
specific gravity can be increased generally, space for
transporting, storing, packing can be effectively saved.
As for products
composed of muti-component or mixed distributed, the
segregation of each component can be avoided though
granulation so as to guarantee the quality of compound
products.
