Big-bags are increasingly being used in the processing of raw materials. After big-bags are emptied, they are often folded. Unnecessary dust is created during folding. This substance emission is avoided by means of a big-bag compactor with an integrated compressed air-cleaned filter, and the amount of waste is reduced to a minimum package. The empty Big-Bags are packed dust-tight at the end in an endless foil. The filter is suitable for very different powders from very fine to very sticky. The unit is mobile or non-mobile wheels, and equipped with its own control / control box. A traditional bag compactor is often used to compact empty big bags, but these often get stuck. The Poeth Big-Bag compactor, however, has been specially developed for big-bags. The system can be supplied fully ATEX certified internally and externally.
