What is a vertical screw conveyor?
A vertical screw conveyor is a helical screw that transfers materials from a lower point to a higher point. The screw is positioned inside a tubular casing, and its rotational movement ensures the upward transport of the conveyed material. These compact and space-saving machines can be integrated into almost any installation. The elevation height of these devices can reach up to approximately 15 meters. This limitation is due to the weight of the material to be lifted and the corresponding motor power.
The feeding of a vertical screw conveyor can be done with a silo, hopper, or transport/dosing device, either integrated or separate from the machine. Many vertical screw conveyors incorporate a horizontal feeding conveyor system because precise dosing of the materials at the conveyor's inlet is crucial for efficient vertical transport. At the outlet, a weighing hopper, silo, or additional transport system can be found.
Types of vertical screw conveyors and applications
The screw of a conveyor can have an internal shaft (sometimes referred to as "solid shaft") or be shaftless. For models with a shaft, top-driven (or pull-driven) mechanisms are generally preferred, as when the drive is located at the bottom, the shaft must be equipped with a seal that needs regular replacement. Shaftless models are preferred for the elevation of sludge and other viscous or sticky materials, which tend to adhere to the shaft of the screw.
Vertical screw conveyors are used in particular to lift
- powders, granules, and ground products;
- sludge and viscous materials from centrifuges, compactors, or mixers.
These machines are found in the food industry, the chemical industry, incineration plants, and in many municipal waste and wastewater management facilities. The parameters to be taken into account when choosing a machine include:
- The type of material to be transported
- Quantities and flow rates
- The height of elevation to be covered
For models equipped with an integrated horizontal feeding transport, the horizontal distance to be covered.
