Massa och papper

Screening, conveying and dewatering
Pulp and Paper sludge, truck receival, storing and conveying


SPIRAC har erfarenhet av vattenrening för massa- och pappersindustrin, samt vissa aspekter av systemdesign och kompletta system för slamhantering.

Våra produkter och lösningar hanterar:

  • Transport och avvattning av grovt avfall
  • Transport av massa och slam
  • Separation av avfallsflöden
  • Klassificering och transport av sand
  • Olika avskiljningssystem för avloppsvatten

Bläck eller lim påverkar egenskaperna för avloppsvattnet i korrugeringsanläggningar och olika produktionsmetoder eller råa produkter i massafabriker kan förändra egenskaperna för avloppsvattnets flöde.

Vi vet att olyckor kan inträffa och mot bakgrund av den kunskapen konstruerar vi robusta produkter och lösningar som alltid ger önskat resultat.

Technical details

  • Shaftless screw conveyor
    The unique design of the shaftless screw allows for higher filling rates and lower RPMs - resulting in less wear, and consequently less demands for repair and down time. The spirals themselves can be made of many different materials, however the primary material is high tensile micro-alloyed steel (HTMAS) - a special steel from Sweden with mechanical properties that deliver incredible strength to the SPIRAC spiral.
  • No intermediate or end bearings
    The more moving parts in a piece of equipment, the more faults that can occur. By eliminating intermediate and end bearings, the need for major maintenance work is reduced. It also allows for more efficient and direct transfer into another conveyor - whether that be horizontal, inclined or vertical.
  • DURAFLO® Type SPX liners
    SPIRAC's proprietary liner - DURAFLO® Type SPX - has been designed specifically to ensure low wear and a long life. A combination of material thickness and formulation gives DURAFLO® Type SPX its unique wearing characteristics. DURAFLO® Type SPX has been developed over many years, and is one of the key features which ensures that SPIRAC conveyors stand as the industry leader. The DURAFLO® Type SPX liner also has a built-in wear indicator with a snap-in, snap-out feature, making it as painless as possible when the time comes to replace it.
  • Totally enclosed troughs
    SPIRAC shaftless screw conveyors come in horizontal, vertical and inclined configurations, and options for either a U-trough or octagonal (OK) trough. All varieties are totally enclosed with elastomeric seals and gaskets, ensuring there is no spillage of the material being conveyed and that odours are completely contained.
  • Direct drive
    Further reducing the downtime and expense that comes along with regular repairs and service, SPIRAC's direct-drive design allows a clean and efficient transmission - without the required maintenance of belt and chain drives.
