CONVEYOR TECHNOLOGY

CONVEYORS FOR CONSISTENT, EFFICIENT, CONTINUOUS MATERIAL FLOWS

Bruks Siwertell offers one of the most comprehensive ranges of conveyors on the market from traditional belt and idler configurations and unique horizontal and vertical screw conveyors, to state-of-the-art, extremely efficient air-supported, low friction belt technology.

INDUSTRY-LEADING INNOVATIONS ensure that our conveyors consistently deliver smooth, safe, continuous material flows for minimal operating and maintenance costs.

When clean, dust-free operations are required, our conveyors can be totally or partially enclosed to ensure maximum environmental protection. They can be configured to meet every requirement and can carry virtually any dry bulk material from low to high capacities.

Worldwide, our conveying systems secure the efficiency of dry bulk material handling facilities, including ultra-large power-generation plants that demand some of the largest volumes of material in the World.

LOW-FRICTION CONVEYING OFFERS WIDE-RANGING REWARDS

This is why we have developed conveying systems that use air-cushion technology, as well as offering our time-tested idler belt and drag chain conveyors. Our innovative air-supported conveyor range includes the Tubulator™ and The Belt Conveyor™.

The Belt Conveyor

We have innovatively combined the use of air-cushion technology with our standard belt conveyors to create The Belt Conveyor. Our customers can now benefit from a high-capacity conveying system that offers minimal equipment wear and very low operating costs as a result of reduced friction in the conveying line.

Our air-supported belt conveyor has a totally-enclosed design that protects the environment from dust emissions and reduces any material losses to a minimum. The Belt Conveyor uses a formed pan to support the belt, with a fully flanged cover over it to make it dust tight. The belt can comfortably conform to the profile provided by the pan without the added stretching needed to travel through a pipe.

The magic of the air-supported belt conveyor is in the way the air is delivered to support the belt. Each 3m section has access to a common header of pressurized air with air pressure sensors and flow meters installed to monitor it. Under the carry-side pan, is a corresponding 3m-long pressurized air enclosure system, otherwise known as a plenum, which delivers air through holes at just the right pressure and airflow to lift the belt for essentially frictionless travel.

Independent plenums of air can be individually set for each installation, matching the delivery of air for each application precisely and accurately. This patented air delivery method allows the Bruks

air-supported belt conveyor to carry a wide variety of materials with diverse physical properties.

The air-supported belt conveyor offers a smooth ride surface, eliminating the bumpiness characterized by traditional idler-supported belt conveyors. Therefore, material is discharged in exactly the same condition as when it was loaded onto the belt.

The system uses a modular design. Its 3m sections consisting of carry side pan, return side pan or rollers, covers, air supplies and supporting structures, form the basis of the conveyor.

Common to all belt conveying methods, the head section contains the drive unit as well as multiple belt scrapers and cleaners. Depending on application requirements, the tail section can have impact beds or plates. In compliance with CEMA guidelines, tensioning on short belts is achieved by screw adjustment and gravity take-ups for longer conveyors.

Typical belt conveyor third-party components like weigh scales, metal detectors, magnets, and material sensor areas, for analyzing moisture content, for example, can all be accommodated.

AIR-CUSHION TECHNOLOGY DELIVERS VERY LOW COST CONVEYING OVER LONG DISTANCES

Tubulator

For operators looking for high-capacity, lighter-density dry bulk material conveying, the Bruks Tubulator TM is a very cost-effective option. It is especially well-suited for long distances, up to 600m and for high overhead installations.

With more than 700 installations worldwide and over 30 years of proven operational performance, even in extremely low-temperature environments, the industry-leading Tubulator has developed into the smartest conveying system on the market.

On a belt width-for-width basis, the Tubulator achieves capacities up to 40 percent higher than comparable conventional idler belt conveyors at low energy consumption levels and is ideal for transporting wood chips, sawdust, bark, pellets and other low-density bulk materials.

As well as its very quiet operating profile and low energy demands, our Tubulator conveyor is totally enclosed. This ensures that it meets the highest environmental protection standards and eliminates material losses from the conveying line.

The easy-to-install conveyor system consists of a drive unit, tail end and the required number of intermediate flanged 6m or 12m pre-assembled modular sections, which are simple to connect. This ensures that it can be customized to suit a huge variety of specific applications from conveying lengths of 20m to 500m.

The conveyor has a free-span of up to 80m when using cable towers, or up to 30m between standard supports, and is self-supporting up to 25m.

The Tubulator comes in two basic forms: one is totally enclosed on the transport and return sides using an air carry return (ACR). In this version the return belt is supported on a cushion of air provided by a separate blower. The second alternative design uses rollers with 3m spacing to support the return side belt, or roller carry return (RCR).

The Bruks Tubulator has very low operating and maintenance costs. These are largely due to the fact that the belt runs on a cushion of pressurized air, which reduces frictional forces to a minimum. This has a positive impact on wear parts, and eliminates idlers, which have their own maintenance requirements, in the conveying trough.

The low-friction air-cushion technology has low power-consumption demands, which reduces operating costs. Its no-load power requirement is much lower than conventional belt conveyors.
