PLASTICS GRANULATING LINES WITH TOP FEEDING GRANULATING EXTRUDER
COMPONENTS AND FEATURES:
Plastic granulating lines are used for granulating PE,PP,PS and ABS clean industrial scraps or wasted and dried plastics in film, rigid or foam form.
Size reduction can be done by Granulator or Shredder according to the form, dimensions and capacity of the line. Form of plastic is important for choosing the right feeding type for extruder. Also moisture of the material is important for the line. Drying before extrusion can be done by full automatic or manual built-in Agglomeration machines.
PLASTICS GRANULATING LINES WITH TOP FEEDING GRANULATING EXTRUDER are especially used for granulating plastics in rigid form. Screw diameter. L/D, degassing zone, melt filter type and diameter are chosen according to the plastic type and form.
Screw is welded by PTA hard welding for extra protection against abrasion. Screw & barrel are hardened by nitration and induction. Bimetallic barrels produced by centrifugal casting are also available.
By using speed controlled main engine, plastics with different density and MFI can be granulated with the same pressure and capacity.
Direct coupling connection of gearbox and main engine, ceramic industrial heaters and inverters lead to high energy efficiency.
Granule Extruders are controlled by user friendly intelligent PLC system and touch screen and Manual control are available.
Plastic Melt Filter:
Melt Filters are used at extruders. By using special screens, filters are used for cleaning contaminants in melt (sand, metal, different plastics) which reduce granule quality.
Plastic Melt Filters are made of special alloy steel suitable for high pressure and temperature. Melt Filters are hardened by PTA hard welding.
Single Plate and Double Plate models are suitable for manual operation. Filter diameter is chosen according to contaminants, type of plastic and extruder capacity.
Automatic Filters are equipped with self cleaning “backflush” system, they are working with minimum melt loss at maximum capacity principle.
Filter plates are moved with hydraulic power and nitrogen gas. Special insulated heaters and precise heat control maximize output quality.
Pelletizers are used for cutting plastic melt in granular form. Hot granules are cooled externally in water tank and dewatered in integrated centrifuge after cooled. Granules can transferred to a storage silo by blower optionally.
PE, PP, PS, ABS plastics can be pelletized full automatically. Vertical or horizontal types are available for different capacities.
Pelletizers are completely made of AISI 304 stainless steel. Pelletizing blades and die are made of special alloy steels and coatings according to the type of plastic. By mobile parts, maintenance period is minimized.
Speed control for pelletizing blades enables changing granule size during operation.
Steam blower can be used optionally for sucking the steam from dewatering centrifuge.
