OPAL INGENIERIE

Among the different conveying solutions available, we find soulless screw conveyors, which allow the transport of any type of product, even the most difficult, whether they are heterogeneous, dry, viscous, wet, sticky, clogging, and more besides. Due to the very large passage section, which remains free thanks to the absence of a central axis, the handling of very large parts is possible. This system is virtually unclogable.

This system is completely closed, to avoid any loss of product, and to adapt to wet, unsanitary or smelly products. This solution saves space and is easy to install, and has very low maintenance costs, due to a simple and robust mechanical system, only the spiral being in motion.

Coreless screws, also called worm screws or spindleless screws, have many advantages. Indeed, their use is widespread in the transport of heterogeneous, semi-fluid, sticky or clogging materials. *

Since the coreless screw has no central axis, it allows the reception and transfer of these materials. They cannot clump together or wrap around this axis, as they would in a traditional system.

This solution is also waterproof, it guarantees the containment of the products and the absence of losses. Being robust and simple, the coreless screw system requires little maintenance and significantly reduces maintenance costs.

The benefits of coreless screws revolve around the following issues:

• Reduced maintenance costs
• Reception, transfer, transport of heterogeneous or sticky materials
• Watertightness and absence of losses of liquid products
• Robustness and simplicity of implementation
• Adaptability and space saving

It is possible to apply these solutions in the field of bio-waste, treatment plants and methanisation. Coreless screws are also used for unsanitary, smelly or wet products. Being perfectly sealed, they prevent leaks during the transfer of these materials.

This system offers great reliability and makes it possible to manage large quantities of inputs or digestate. Being soft and flexible, it makes it possible to rethink the configuration of an installation. The space saving is significant whether the transport of materials is carried out horizontally, vertically or obliquely.
