1. The dosing screw should always be integrated with the dosing silo, and if the dosing silo is not delivered by CFN, the dosing screw should as a minimum be delivered by CFN. The reason for this is that the dosing screw is integrated with the PLC program of the briquetting press, where the dosing screw can be regulated to secure maximum or constant capacity of the briquetting press – read about this under options for the briquetting presses.
2. The silos are built in sections with a height of 0,9 m. The standard silo has corner in-serts to prevent material from getting stuck in the corners, when handling raw mate-rial that tends to build bridge as e.g. MDF dust, the corner inserts are replaced with a cone to prevent the material from bridging across the scraper arm.
3. The dosing screw and scraper arm are also important, as the size of motor and gear will vary in accordance with size of silo and type, weight, and size of raw material. The size and shape of the extraction arm is also important. CFN typically works with two extraction arms – a spring-based extractor with many layers and a fixed arm. Further-more, CFN’s extraction units can be equipped with a cone for certain raw materials and for other raw materials a special insert in the silo can be made
The picture on the left shows a silo with a 1-2m3 gross volume. Suitable only for one BP2000 briquetting press.
