Shaftless Spiral Conveyors SSC

Shaftless Spiral Conveyors SSC. Problem-free conveying of difficult materials
  • SSC Shaftless Screw or Spiral Conveyor are an alternative concept to traditional shafted screw conveyors.
  • Material is conveyed by an extra heavy-duty shaftless screw that slides on a wear-resistant, low-friction liner inside the conveyor trough housing.
  • The longitudinally divided U-section troughs are manufactured from carbon or 304 L / 316 L stainless steel, including an appropriate surface treatment.
  • Fabricated parts, except the ultra heavy-duty screw, are of the medium heavy-duty type.
  • The cross section of the lower part of the trough is slightly wider than the side channels to allow for the liner to be inserted in the lower trough part.
  • After complete assembly of the trough the liner is kept in place by the upper trough side channels.
  • At one trough end there is a vertical or flush-type outlet.
  • At the drive end the screw conveyor is equipped with an end plate holding the end bearing assembly with flanged shaft coupling to the spiral.
  • The installed drive unit suits the application.
  • SSC can be loaded from above into the open trough (standard), or through an inlet spout included in a bolted trough cover (option), or from the side through a special side inlet in the loading zone of the trough (option).
Function
  • Shaftless screws (spirals) offer a larger volume capacity and the possibility of handling particularly difficult materials like those that tend to become tangled up or those that present highly variable particle size.
  • Material properties, oversize thickness, as well as a special manufacturing process make the spiral highly resistant and extremely durable.
  • Due to the absence of intermediate bearings, obstacle-free material handling is guaranteed. The completely enclosed trough prevents any material leakage.
  • Trough covers with appropriate gaskets enable odour-free operation and form a barrier preventing any atmospheric agents from entering the system.
  • At the same time the conveyor offers maximum access to its inside for inspection and cleaning. Maintenance is reduced to the minimum due to a limited number of components.
  • There is a vast choice of liners depending on specific characteristics of the material handled.
  • SSC Shaftless Screw (Spiral) Conveyors are designed for handling of difficult heterogeneous materials such as urban solid waste, screenings and floating matter, de-watered, thickened, conditioned sludge, packaged food, creams or pastes, as well as waste from meat, fish, fruit and vegetable processing.
  • The main sectors of application are: waste water treatment, sugarhouse rejects, fish industry, solid waste treatment, fruit and vegetable processing plants, beverage industry, pulp and paper, chemical industry, food industry in general, meat processing plants, abattoirs/slaughterhouses, restaurants, canteens, and catering in general.
Features
  • Troughput rates: up to 65 m³/h (38 cfm) for sludge; up to 25 m³/h (15 cfm) for screenings.
  • Drive power: 0.55 kW (0.75 HP) ~ 7.5 kW (10 HP).
  • Trough and spiral manufactured from carbon steel or 304L / 316L stainless steel.
  • UHMWP trough liner.
Benefits
  • Simple design (few components).
  • Small footprint.
  • Odour-free operation.
  • High efficiency.
  • Complete emptying.
  • High degree of self-cleaning.
  • Easy to access and clean.
  • Low maintenance.
  • Modular components enable easy adaptation to various problems (extremely versatile conveyor for a variety of DIFFICULT materials and a large number of applications).
Options
  • Bolted trough cover.
  • WAM standard inlet spouts.
  • Inspection and overflow hatches.
  • Drainage kit.
  • Trough feet.
  • Washing nozzles.
  • Different type power transmissions: direct, coupling transmission, chain transmission, belt transmission.
  • Different liners available: with wear signalling, bottom bars or plates, white or black colour plastic.
  • Spiral guiding bar.
