The granulation unit for the parallel twin-screw extrusion unit,
can effectively complete the recovery of raw materials for PET
extrusion granulation,
Characterized mainly as follows:
1, with the parallel twin-screw extruder barrel, screw design and
manufacture of using building-block principle. Processing of
materials systems and processes according to requirements of its
aspect ratio formula barrel structure, and screw arrangement, ring
structure, exhaust the number of location, feeding method,
electrical control methods, can optimize the rational allocation.
To achieve multi-functional, multi-purpose to accommodate the
processing of polymer materials.
2, a new type of slow distribution of transmission, high-torque
design, high-precision gear machining, tooth decay bearings
imported parts, reasonable oil-soaked style with forced lubrication
device, and chain protection device to ensure reliable and smooth
operation of the host.
3, full use of the limited space design-to-date Involute Spline
Shaft formal structure. Ensure maximum carrying capacity, high
torque transmission. 4、
4, using computer-assisted design of components for the kneading of
screw-type. Has excellent self-cleaning function, good
interchangeability, their specifications transmission block, mixing
block, kneading blocks, counter-current block and gear-type plate
and so on, through appropriate and reasonable combination to
achieve the delivery of materials, plastics, shear , decentralized,
homogenization, venting, etc. to build pressure to complete the
processing of polymer materials technology.
5, according to materials in different states, feeding system using
a variety of structural form, there is a single screw, twin screw,
twin-screw of non-engagement type, hollow spring-loaded,
double-stage type and size of metering pumps and other metering
feed. Weight loss can also be equipped with metering charging to
complete a higher measurement requirements.
6, unit of electrical control system of the main parts are
imported, could be designed as: separation unit control, analog
panel displays, PLC system, PEC system control, etc. available.
7, granulating system can be used a variety of ways to meet the
requirements, water-cooled brace pelletizing; air-cooled die face
look; water ring die face look; eccentric mist earnest; water,
underwater die face look so.
8, regular use of high-quality nitrided steel barrel nitriding
surface treatment or high-performance bi-metal alloy cover, but
also can be used tool steel liner kits, screw element with
high-quality nitrided steel surface treatment, engaging in
high-speed tool steel and wear-resistant corrosion-resistant wear
special surface treatment to adapt to different types of
processing.
9, machine-based installation-free way of leveling the ground can
be requested without cement watering is very convenient.
10, Adaptation: Fill modified, glass fiber (carbon fiber) enhanced
all kinds of Color Masterbatch, Rubber Blend, plastic alloys,
functional masterbatch, all kinds of cable material, reactive
extrusion, devolatilization processing, powder coatings.
