To ensure correct fixing of a Pro-SLOT® wedge wire screen basket (which works dynamically as a part of vibrating sifters) to the frame of the sifter and extend its lifespan, a special strengthening must be designed, which depends on the load and a given frame. The baskets for every type of drainer or centrifuge are available. Optionally, a centrifuge basket with abrasion-resisting coating (hardened surface of the screen) may be prepared.
