In order starting from left: VPP-S VPP-M e VPP-L
The primary scrapers act tangentially on the head drum of the conveyor belts unidirectional and have the purpose of eliminating the majority of the residues of material from the tape and to direct it in the discharge zone.
The VPP model is built in three size to fit various diameters of the drums. The scrapers polyurethane antiwear 80 sh are suitable for materials with a low degree of abrasion and their particular shape, with the absence of protrusions, facilitates the fall of the material in the discharge zone. The pressure on the tape is obtained from the dual effect, combined elasticity of the blades and the system side of spring pressure. For belts with widths between 1400 mm and 2000 mm, the systems are two sides of pressure. All metal parts are powder coated polyester and bolts are in stainless steel AISI 304.
On request it is possible to realize the scraper in stainless steel AISI 304 or AISI 316.
