Screw conveyors: energy efficient, environmentally friendly and minimal running costs

SCREW CONVEYORS: REVERSING THE TRACK ON ENERGY EFFICIENCY, ENVIRONMENTAL PROTECTION AND LIFETIME COST PROTECTION
Today, hundreds of facilities, from industrial facilities and port terminals to ships, silos and power plants, benefit from the unique capabilities of our screw conveyors. They offer some of the most outstanding dry bulk material handling characteristics on the market. Here are some highlights:

ENVIRONMENTAL PROTECTION
Screw conveyors have very low energy consumption and are totally enclosed, protecting the environment by ensuring that dust emissions and spillage are eliminated when transporting all materials. They can handle virtually any dry bulk and are ideal for powdery and dusty cargoes, especially where scrupulously clean operations are essential.

OPERATIONAL FLEXIBILITY
Screw conveyors can be supplied with multiple entrances and exits, allowing very flexible freight distribution arrangements. They can be delivered as stand-alone units or as part of complete bulk material handling systems and are available in multiple diameter sizes to suit a wide range of applications, and capacities range from 30 to 1,700 m³/h.

Screw conveyors operate with helical flight moving bulk material forward through a spinning action. A vertical screw conveyor can elevate materials up to 40 m, the combination of several conveyors in series makes it possible to elevate materials to any required height. The same principle applies to horizontal conveyors, which can also be inclined and reversible.

BENEFITS OF LOW WEIGHT
Our screw conveyors are lightweight with a very small physical footprint. This makes them ideal for jetties with weight restrictions and when installing a conveyor system into existing infrastructure. For example, vertical screw conveyors require much less space than a bucket elevator, making them ideal where space is limited.

LIFETIME COSTS
The rigid and robust construction of our conveyors reduces wear and allows easy maintenance at infrequent intervals. Our screw threads offer some of the longest life in the industry.

THE R&D PROGRAM PROVIDES SIGNIFICANT BENEFITS TO THE OWNER
Bruks Siwertell can now reveal the extremely positive results of its recent innovative research and development (R&D) programme, aimed at improving the life of the vertical screw conveyor in its market leading range of Siwertell technology. Read more
