Extruder Feeding System. Densifier. KSW type.
The Densifier KSW type is used for extruders with not-optimally-free-flowing products such as ground material, punching ribbon, powder, agglomerates, film flakes and fibers.
Filling: The material to be processed, is fed into the feed hopper of the densifier. Filling level.The filling level of the KSW is monitored with a level-indicator.
Loosening: If necessary, the material is loosened up in the bin by means of special agitators and scrapers.
Pre-compaction: The material is pre-compacted via the densifying screw.
Extruder feeding system: The compaction of the material via densifying screw and the feeding of the extruder with constant pressure ensures optimal loading of the extruder with material.
Throughput: 220 – 8819lb/h (100 – 4,000 kg/h) – film flakes
440 – 19841lb/h (200 – 9,000 kg/h) powder
Options:
Lifting system: The densifiers may be equipped with a hydraulically-operated lifting system with manually-operated pump. This device ensures the quick and easy lifting and swinging away of the aggregates from the extruder for easier cleaning and maintenance.
Coating: Special coatings of the bin and of the densifying screw for products that tend to stick.
Extruder feeding system. Special feed hopper.
For the direct refeeding of edge-trims or production waste into the production extruder, a special feed hopper is required. In most cases the recycling material (film flakes, ground stock) and free flowing granulate (virgin material) can be mixed.
Direct refeeding: No additional thermal stress of the material is caused, absent intermediate granulation, by direct refeeding.
Filling: At the end of the film line, the edge trims are ground and fed into the special feed hopper. Simultaneously, granulate can be conveyed into the same hopper over a second inlet pipe.
Mixing: Regrinds of edge trims/production waste and granules can be mixed by means of a screw.
Feed-extruder: An adjustable feeding screw ensures constant feeding of the extruder.
Throughput: 220 – 2204lb/h (100 – 1.000 kg/h)
Volumetric metering system. VDOS type.
Volumetric dosing of the VDOS series is perfectly suited for dosing of bulk materials with good- to moderate flowability.
Function: The metering screw essentially consists of a screw-trough with a large feeding area to ensure a continuous feeding level for the screw.
Storage container: The modular storage container can be adapted from 75 to 150/300/450 and has a lid with inlet and vent opening.
Drive: An AC motor drives the screw.
Metering capacity: The metering capacity in combination with an FU control is in the range of 8 to 1,321 gal/h (30 to 5,000 l/h)

Pneumatic conveying systems
Pneumatic conveying systems for gentle, dust-free and separation-free bulk solids. According to the application, the conveying systems are designed as vacuum conveying, pressure conveying or vacuum-pressure-combination.
Vacuum conveying: A vacuum is created by means of a vacuum blower. Via a suction line, the bulk material is carried by the material feed to the conveyor separator. There, the air is separated from the bulk material. The bulk material can exit the system via a free flap or a self-operating outlet flap (Discontinuous conveying).
Construction: Conveying performance up to approx. 4409lb/h (2,000 kg/h)
Pressure conveying: A vacuum is created by means of a vacuum blower. Via a suction line, the bulk material is carried by the material feed to the conveyor separator. There, the air is separated from the bulk material. The bulk material exits the system via a free flap or a self-operating outlet flap.
Construction: Conveying performance up to approx. 44,092lb/h (20,000 kg/h)
