Continuous Conveying without Moving Parts
Thursday 15. May 2008 - Kongskilde is introducing a new Venturi system for the pneumatic conveying of off-cuts, reject parts and edge trim from the plastic and paper industries. The system is characterised by conveying material through a pipe system without obstructions or mechanical moving parts.
The essential part of the system is the Kongskilde ITF Venturi connecting to either 160 or 200 mm diameter pipes, which creates an extensive capacity for removal of, for example continuous edge trim, from the production line.
As there is no perforation inside the conveying system, particles from the conveyed material will not block the inside. Likewise, the lack of rotating parts eliminates the risk of winding troubles or blockages in the material flow. Based on these facts, the system is very suitable for thin and light materials containing particles that would normally block an air return system with perforated parts.
To access optimum flow of the conveying air, the system can be combined with either our Multiair blower or our TRL blower. The blower creates the airflow by building up an air pressure inside the chamber surrounding the ITF Venturi. The air is then led through a gap to the outlet and is thereby creating an efficient vacuum inside the full length of the conveying line.
The diameter of the pipe inside the Venturi and the diameter of the conveying pipe are the same. However, the pipe connecting to the Venturi discharge has a larger diameter to counter the additional air volume on the discharge side of the Venturi.
The system is designed with no air return, therefore the blower does not heat the conveying air. It also means that the air volume to be separated from the material in the separation unit at the end of the system is higher compared to systems with air returns.
The blower and the Venturi are placed close to the discharge end of the system. This makes the material intake easy to install and does not even require any kind of feeder. The material is simply vacuumed through a continuous pipe right from intake and then blown from the Venturi to the discharge.
Kongskildes ITF 160 and 200 Venturi are simple and stable systems with a high conveying capacity for edge trims, reject parts and other off-cuts from the plastic and paper industries.
