Why refurbish?
With our sustainable screw conveyor refurbishment, you can significantly extend the service life of your screw conveyor – economically and in an environmentally friendly way. Compared to a completely new screw conveyor, our refurbishment solution significantly reduces CO₂ emissions and thus actively contributes to climate protection.
Customised screw conveyors for every application
Our screw conveyors are ideal for transporting powdery, semi-solid or liquid materials. We manufacture screws in a wide variety of designs – precisely customised to your requirements and conveying quantities.
We produce screws depending on the area of application:
- made of stainless steel – ideal for the food industry and technical ceramics
- made of wear-resistant special steel – with armoured outer edges on request
- with spirals made of REHART composite armour plates for maximum load-bearing capacity
- made of steel for hydropower plants, in sizes up to 22 metres in length and 4 metres in diameter
Flexible installation solutions – rising, falling or horizontal screw conveyors
Our screws can be installed horizontally, ascending or descending as required – for maximum flexibility and optimum conveying capacity.
Robust, resilient and highly versatile
We supply open augers for installation in machine housings or for installation in concrete troughs – custom-fit and robust. Alternatively, we can equip your screw conveyor directly in the factory with a metal pipe casing to provide a compact and protected solution.
Our screw conveyors are customised systems that we manufacture ready for installation according to customer requirements, either with or without preventive wear protection. This enables us to guarantee maximum efficiency and durability.
As many industrial applications require a high level of wear resistance, we offer a broad portfolio of wear protection solutions. This not only increases the service life of your screw conveyor, but also significantly reduces downtimes and maintenance costs.
Refurbishment and preventive wear protection with ceramic composite materials
If screw flights are bent, worn or worn out, we offer professional screw refurbishment using innovative processes – often beyond the original quality. One particularly effective method is coating with the ceramic composite material nanoseal. This highly wear-resistant coating can be applied over the entire surface or only in areas subject to particular stress.
Our strength lies in our versatility: we customise each refurbishment to your individual technical requirements – for maximum service life and minimum downtime.
Third-party products? No problem.
We refurbish not only our own products, but also screws from other manufacturers. We are particularly specialised in the refurbishment of screw conveyors that are used under extreme conditions.
