CUSTOM INDUSTRIAL HANDLING SYSTEMS
Screw Conveyors
Screw conveyors are used for the movement of powdery, granular and pasty products in dosing systems or simply for horizontal, vertical or inclined transport.
All this can be done using continuous spirals (with 1 or 2 starts) with a constant pitch, obtained from flat steel bars, welded onto the spiral-holder shaft or via pressed steel sectors available with different pitches.
It is also possible to move wet or liquid products using special seals on the heads, a useful measure if there is a need to sanitize the inside of the box and the spiral-holder shaft of the conveyor without compromising the mechanical and electrical parts outside the box itself.
In particular cases in which the product is extruded and the box heats up, it is possible to equip it with a liquid cooling circuit and external insulation.
Depending on the type of product, hourly flow rates and speed, our technical office will decide the most suitable section, pitch and materials to use that are most suitable for the system that the customer needs to create.

- Galvanized steel (galvanic or hot dip)
- Stainless steel (AISI-304 or Aisi-316) satin finished (medium grain or scotch-brite for food and pharmaceutical use) and non-satin finished (for industrial use and for high temperatures)
Options
- Choice of component brand (motor, reducer, supports, bearings, etc.) as an alternative to our standard offer (Varvel, Seipe, NSK/Tecom, Skf, etc.)
- Electrical system and on-board machine according to customer specifications (regulations, brands, etc.)
- Pneumatic system and wiring (our standard Metal Work or brand on customer request)
Advantages of Screw Conveyors
The adoption of conveyors brings a series of benefits, measurable both in terms of efficiency and savings on operating costs.
Reduction of manual handling
- Reduction of operator travel: Safe automation of transport reduces downtime and risks associated with manual handling.
- Continuous and controlled flow: electronic management of the belt eliminates most of the interruptions typical of manual systems.
Greater logistics efficiency
- Integration with existing automated systems: Conveyors can be easily connected to production lines, picking systems or sorting plants.
- Reduced operating costs: a linear and controlled work cycle significantly reduces downtime and ensures greater handling speed and efficiency.
