PST - Shaftless Spirals
We mainly manufacture shaftless spirals; which are made in a great variety of sizes. We produce both single spirals, and spirals fitted with one or more inner spirals, which increase both capacity and strength. The advantage of using a shaftless spiral is its high capability of coping with both large volumes, and difficult materials; threadlike, sticky and irregular particles can all be handled without getting stuck in the spiral.
