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 VPT model is realized in two sizes to fit various diameters of the drums.
The scrapers mounted on elastic supports are made of tungsten and suitable for materials with a high degree of abrasion and particularly sticky tape. Each pallet has a baffle in Aisi 304 stainless steel that deflects debris material removed from the tape to the unloading area. The pressure on the tape is obtained from the dual effect, combined elastic support of each element and wiper system-side pressure spring.
For belts with widths between 1400mm and 2000mm 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.
