30.04.2018 Bag compactor modified to process bulk bags too

Van Beek, Drunen, the Netherlands, has adapted the latest version of its used sack compactor – which was launched at the beginning of 2016 – to enable it to process used FIBCs as well in an efficient, cheap and environmentally friendly way. The internal screw compresses empty bags, reducing their volume by some 60-80%. 
This latest development comes in answer to customer demand. “Big bags are bigger and made of a coarse fabric that is a bit more difficult to compact”, said Joram van der Heijden, sales engineer at Van Beek. “During testing it was found that big bags are in particular more difficult to feed into the screw. To draw big bags into the screw, we devised a technique that exerts extra pressure on the bags and as a result big bags are fed properly into the screw and then compressed.”
The bag compactor can be used for plastic bags, jute bags, cardboard bags and combinations of these. Van der Heijden went on: “The machine has many different designs. The standard design is a steel coated version. For bags containing residues of aggressive powders that come into contact with steel, we have stainless steel versions.” For processes in an explosive atmosphere an ATEX-compliant version is available. By using a chute, the empty bags can be fed into a continuous process. A mobile version of the bag compactor is also available.
According to Roel Kneepkens, sales engineer at Van Beek, the biggest advantage of the bag compactor is in the cost saving. “A hydraulic system is not in fact necessary to drive this press, only electricity. As a result the bag compactor is many times more economical and sustainable than a hydraulic press.”
