ROTOBOX SCREW EXTRACTOR
PLANETARY EXTRACTORS FOR HARD FLOWING POWDERY PRODUCTS
The extraction of POWDERY PRODUCTS from silos and storehouses is not so easy as it seems: powdery and compacting bulk behaves differently any time and can cause a lot of problems.
BSP Planetary extractors collect the product from the whole surface of a flat bottom silo and convey it towards the central outlet.
The most important technology to extract hard flowing products from flat bottom silos is the B.S.P. ROTOBOX PLANETARY EXTRACTOR constituted by a metallic beam crossing the silo diameter.
Suitable to any field and to any product: industrial, food, chemical and plastics, aggregates, sludges and depurations, wastes and biomasses, animal’s meals and vegetables flours.
