For the conveying of filtered-out materials to silos or containers. Pneumatic low-pressure conveyor systems For the conveying of filtered-out materials to silos or containers and for conveying distances of up to 200 m. The conveying air stream is generated by one or more fans. Product description Pneumatic low-pressure conveyor systems can be implemented as a single-pipe system or a ring system. In the case of the single-pipe system, a final separator in the form of a filter or a cyclone is always necessary. In a ring system the conveying air is driven in the ring. In this case the silo or container acts as the separator. Light dust particles that are not separated in the silo or container initially remain in the circulation. With most materials the fine dust particles tend to attach themselves to the coarser ones and are thus separated with them. Hence, a concentration of the fine dust particles in the conveying stream is avoided as far as possible. The loading of the conveying stream essentially depends on the grain size, density and form of the material to be conveyed. As a guiding value, one may assume 250 - 300 g/m³. Higher loads are possible under certain conditions. In cases where there is a high amount of material, e.g. in planing works, where the splinters are directly removed and transported away for further use, this can also be realised with a ring system and several containers. Switchover takes place automatically when the container signals that it is full. Containers are exchanged during operation.

Feeding of filtered-out materials to silo systems over long distances (up to 700 m). Pneumatic medium-pressure conveyor systems For the conveying of filtered-out materials such as wooden splinters and wood dust or for the conveying of products in the derived timber products industry with large conveying quantities over great distances. Pneumatic medium-pressure conveyor systems are economical, reliable and enable flexible adaptations to individual conveying routes. The conveying air stream is generated by a rotary piston compressor. As opposed to fans, these have almost vertical characteristic curves; i.e. the volumetric flow rate remains almost constant as the pressure in the conveying system increases. This ensures safe material transport. Special cellular wheel sluices are necessary for channelling the conveying material into the conveying stream, such as knife gates for derived timber products. Cyclones, filters or combinations of the two are used to separate the conveying material from the conveying stream. The economical conveying lengths lie between around 150 and 750 m. The loading of the conveying stream can amount to up to 5 kg/m³ and essentially depends on the grain size, density and form of the material to be conveyed.

Cellular wheel sluices Cellular wheel sluices are used as discharge devices under filters, cyclones and silos, as well as for channelling materials into pneumatic conveying systems. In a special tested version, however, these can also be used at the same time for the explosive decoupling of complex plant systems in the sense of the ATEX regulations. Multi-cutter The multi-cutter is ideally suited for the chopping up of paper or plastic waste strips as well as veneer residues in extraction pipes. It works with a set of fast-rotating, but air-permeable blades. The connection diameter is DN 160 and the motor has a rated drive power of 0.75 KW. In order to be able to definitely assess the usability for the application, it is advisable to provide us with representative material samples. The assessment is also often proven by pilot plant trials. The advantage of this is that the degree of chopping can also be determined. ATEX non-return valves (EX) Non-return valves are passive decoupling elements in pipelines for preventing dust explosion effects from running in the opposite direction to the conveying direction. The non-return valves are type-tested protective systems in accordance with directive 94/9/EC, better known under the synonym ATEX 95. Function In normal operation, the top-mounted flap swims on the air stream in the housing of the non-return valve and in this way is held open. At a standstill the valve flap closes under its own weight and rests on the diagonally cut inflow pipe. If an explosion occurs behind the non-return valve, the air flow direction is reversed due to the increased counter-pressure. This causes the flap to close. The valve flap is additionally pressed against the inflow pipe by the pressure of the explosion, thus reliably sealing the pipeline against an explosion backdraught. These non-return valves function without external energy. The RSK and BPF-M series are available in the sizes DN 160, 200, 250, 280, 315, 355, 400, 450, 500, 560, 600, 630, 710, 800, 900 and 1,000. The two series differ in that they have different versions and application possibilities. The non-return valves, as type-tested protective systems, are sold through Brilex Gesellschaft für Explosionsschutz mbH, Hinterm Gallberg 15-17, D-59929 Brilon; www.brilex.de

With direct drive, V-belt drive or coupling drive. Industrial fans Fans are used in countless industrial plants. If the fan fails, the plant must be shutdown and production stopped. These fans are in operation around the clock, often under adverse conditions (heat, wear and aggressive media), in order to guarantee the production process. Our fans prove their reliability every day in the cement, glass, steel, wood or recycling industries, to name but a few examples. Our fans are used in the foodstuffs and chemical industries as well as in mushroom growing or agriculture. We offer you an individual technical solution adapted to the respective conditions which, in addition to function and reliability, also takes into account energy efficiency. In partnership-like cooperation with our customers, we develop economically sensible ventilation systems. Our range of services extends from planning, manufacturing, installation and commissioning to after-sales service. In addition to on-site balancing, we supply you with spare parts and also install them on request.

Wear-protected industrial fans. Wear-protected industrial fans Solids are often transported with the air that are very abrasive (e.g. corundum, sand, quartz, wood). These solids lead to considerable wear, in particular of the fan impeller. Progressive loss of material takes place, which can lead to machine failure. By means of specific measures to prevent wear, the service life of the fan can be extended. In addition to a suitable blade geometry, austenitic manganese steels and build-up welds can be used to counteract impact and sliding wear.

For the conveying of gaseous materials. Gas-tight fans If the conveying medium of a fan must not be allowed to penetrate to the outside (e.g. gases that are harmful to health), our fans are equipped with a multi-chamber labyrinth seal on the shaft gland. Depending on requirements, the seals are provided with a sealing gas connection or a grease seal. Under certain circumstances the sealing gas can also be connected to the suction side of the fan. Naturally the flange connections are sealed accordingly and the fan housing is welded gas-tight and tested.

For the conveying of explosive dusts or gases. Explosion-proof fans For the conveying of explosive dusts or gases, out fans are equipped with spark protection at the impeller inlet. Both the shaft seal and the drive train comply with the regulations of the European ATEX directives.

For the transport of large solid particles with the conveying stream. Transport fans Fans can also be used for the transport of materials. A suitable blade shape and the employment of open impellers enable the transport of large solid particles with the conveying stream. Thanks to our large selection of impellers we can ensure the trouble-free flow of material. Apart from the wood industry, our clientele includes the plastics and paper industries.

For pressure ranges from 3,000 to 16,000 Pa. High-pressure fans The field of application of high-pressure fans extends over almost all branches of industry. Our high-pressure fans cover a pressure range from 3,000 to 16,000 Pa. Thanks to their simple and solid construction, these fans know how to convince. Whether they are used as a blower in an industrial washing machine or as a ventilation fan in a compost works, these machines perform every day.
