Whenever complex, three-dimensional parts can "wriggle" through the separation gaps of roller separators or perforated drums, tube separators (also called hedgehog drums) offer a perfect solution. The tubes welded to the outside of the perforated cage reliably ensure a snag-free and secure separation result.

Components that could otherwise wind their way through gaps or holes only penetrate the tubes to a certain point and then fall back into the separation area of ​​the drum cage. These shell separator drums are therefore particularly suitable for separating very complex, diverse part geometries. The drum cages and shell tubes are manufactured entirely from stainless steel, so these separator drums can also be used in cleanroom environments. Depending on the specific requirements, these separator drums can be manufactured with separation lengths of 700 mm, but optionally also 500 mm, 1,000 mm, or 1,200 mm. The design of the hole and shell tube geometries, the hole spacing, and the length of the shell tubes is completely customized to the customer's specifications, depending on the material to be separated. If required, the drum cage can also be divided into several zones with different hole geometries, allowing more than two different products to be sorted separately. The drum cage simply rests loosely on the base and can be easily exchanged for other drum cages (other sleeve separator drum cages, hole cages, roller cages, rectangular cages). This allows for the maximum range of parts to be processed. These special separator drums are primarily used in the plastic injection molding industry or in die casting for separating the sprue and the good part, and once again exemplify the customer-specific design of MTF-Technik equipment.
