Screw conveyor is divided in two types rigid screw conveyor and shaftless screw conveyor. Rigid screw conveyor is suitable for nonsticky powder and small particle material such as cement,fly ash,lime,flour,starch,food additive etc. Shaftless screw conveyor is suitable for sticky and easy winding materials such as sludge, biomass.
Shaftless Conveyors STS Description and Working Principle. STStype Shaftless Spiral Conveyors follow the principle of traditional shaftless screw conveyor design. The shaftless spiral is driven by a direct drive without the need for hanger bearings. Lengths of up to 40m are achievable without hanger bearings.

Shaftless Spiral. The Spirotech Shaftless Spirals are manufactured from the highest quality High Tensile Steel and can be used in extremely high torque applications. For abrasive conditions Spirotech Spirals can be treated by means of hard facing, nitriding, ceramic lining and various well recognised abrasion resistant techniques.
Atara Equipment Ltd designs and manufactures shaftless screw: live bottoms, conveyors, compactors, classifiers, channel screens and grit chambers. Atara Equipment Ltd is recognized as a leader in its field, with over 350 installations in waste water treatment plants, and more than 150 in diverse industries throughout North America and Europe.
Due to this fact the calculation and design of such conveyors demands a lot of experience. The well known analytical models and standards for the calculation and the design of screw conveyors [15] or shaftless screw conveyors [612] (Fig. 1) incorporate socalled adjustment factors.
The JDV Shaftless Screw Conveyor is a proven design to reliably transport solids with a lower total cost of ownership when compared to other transport methods. The Shaftless screw conveyor flight design allows for a greater fill rate versus other methods/equipment, increasing operational efficiencies and lower initial capital investment.
Orthman screw conveyor systems and parts are readily available and supported by a responsive service network. Orthman screw conveyors can be furnished with all necessary power transmission components, including Vbelts, sheaves, motors and guards, all precisiondesigned to work with the screw conveyor .
The shaftless screw conveyor is the solution for conveying many difficult bulk solids. In fact, the shaftless conveyor was so successful in the Environmental industry, that its use has been promoted in many other industries such as chemical, food, and minerals processing.
Conveyors. CTM also design a whole range of bespoke screw conveyors, both shafted and shaftless. All of these conveyors are tailor made to suit the individual application such as length, material handled, throughput, horizontal or inclined, method of being fed, single or multiple outlets, cantilevered stockpiles or simply supported, fixed or mobile.
Shaftless Screw Conveyors as do standard screw conveyors can be manufactured in a variety of materials such as Mild Steel, Stainless Steel, and other alloys. The spiral of a shaftless conveyor is considerably thicker than a standard flight, which is required in order to maintain the spiral rigidity.
Shaftless Screw Conveyors are ideal for vertical conveying. Since they do not require a nondrive end bearing this eliminates the need for high maintenance bottom shafts and seals on a pulling shaftless vertical conveyor. A shaftless vertical feed is obtained by directly connected pushing shaftless conveyor which optimizes layout design ...
PST Shaftless Screw Conveyors by PST AB. For decades PST Shaftless Screw Conveyors have proven themselves to be an exceptional solution for the conveying of many types of materials. The uncomplicated design of the Shaftless Screws means safe, relia...
Shaftless Spiral (Screw) Conveyors are designed for handling of urban solid waste, screenings and floating matter, dewatered, thickened, or conditioned sludge, packaged food, creams or pastes, as well as waste from meat, fish, fruit and vegetable processing.
The heart of any shaftless conveying system is the Serpecon shaftless spiral, coupled to a gear box and combined with a serpecon stainless steel trough and the serpecon proprietary conveyor liner. Serpecon's shaftless screw conveyors are totally enclosed with gaskets to reduce odour and ensure no spillage of the materials being conveyed.
