SPU Secondary Scraper with Polyurethane Blade
Scraper Blades
They are placed perpendicular to the direction of movement of the belt, thanks to their special design, they prevent the accumulation of the scraped material. The blades are tungsten based and have a very high abrasion resistance and are mounted with 2 bolts to the rubberised saport. This makes them very easy to install.
Saports are designed to provide flexibility to the blades. The rubber saports are extremely effective in absorbing vibrations and incoming impacts. Saports are in rubber segments and each segment is 124 mm wide. They are easily mounted on the main axle. They are manufactured with a combination of two different hardness rubber. The hard rubber segment (the part that surrounds the axle) provides a firm grip on the axle, while the softer segment (the curved part) provides flexibility to the blades in all directions.
The saport contains an adjustable pressure system. The pressure system is connected to the fixing arm of the scraper. This fixing arm is a very robust structure made of L-profile. Saports have a slide system to determine the position of the scraper. Saports have an expansion of 200 mm on both sides. In this way, they can be adapted to different widths of belt chassis.
