Rotary-Valves
For dosing, sealing, feeding, discharging as well as measuring of bulk-solids. They are used for a broad range of bulk-solids like ashes, coal, cement, sewage-slurry, plastics, crystalline acids, methyl cellulose, carbon black or any other products in dusty or grainy condition. Standard Rotary-Valves work on the principle of volumetric-transport. The bulk solids are falling from the Inlet section into the mostly star shaped chambers by force of gravity. While the rotor is turning, a determined volume of the bulk-solid is moved towards the outlet. Based upon the fixed geometry of the rotors chambers, the conveyed volume is well defined. Our product-range provides various options, designs and materials. We offer a standard-product made from cast-iron, where all parameters which are not related to the housing can be configurated to match your bulk solids characteristics. Over and above we produce Rotary-Valves as a weld-construction, which are available in all customary materials. We provide plenty of options and extra equipment to perfectly serve all of your requirements, which arise from the conditions of your bulk-solid. As a result of our long-term development, we are able to provide standard Rotary-Valves for cement and rough materials in welded-design in highest quality with short delivery times and at an exceedingly competitive price. Our sizing ranges from 80mm – 2300mm rotor-diameter.

Rotonivo® - The rotary paddle level switch from UWT operates reliably and maintenance-free and offers a compatible solution for plants for safe level detection in bulk solids.
Depending on the requirements, the Rotonivo® rotary paddle switch is used as a full, demand or empty detector in storage silos or process vessels and is suitable for use in almost all solids. With its simple electromechanical measuring principle it can also be adapted for extreme process conditions. A motor driven shaft causes the vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, this creates a torque, which is converted via a switch to an electric signal. Once the vane is free again of the material, the output signal is reset and the motor driven shaft rotates again. This reliable and maintenance-free limit switch for safe level detection in bulk solids has international approvals for use in gas and dust hazardous areas and is also certified to SIL 2.

Rotor
The SHW rotor is the ideal discharge unit for nearly all poorly flowing bulk materials. The drag arm position and drive torque automatically adapt to the flow behavior of the bulk material. The system is highly versatile and is particularly suitable for bulk material reception and intermediate storage. It is specifically designed for round silos with diameters of up to 7 meters and enables uniform bulk material distribution throughout the entire process chain. In combination with the proven SHW unloading system, stable bulk material bridging can be effectively prevented, even in silos with unfavorable geometries. Discharge is continuous and reliable, with a conveying capacity of up to 300 cubic meters per hour per discharge screw. Up to six discharge screws can be fed simultaneously, ensuring exceptionally high operational efficiency. Thanks to its extremely robust design, the system offers high availability and a long service life. An optional wear protection system can be integrated to provide extended durability, even when handling highly abrasive bulk materials. The maintenance-friendly design simplifies operation and minimizes downtime. Overall, the system provides a reliable and high-performance solution for a wide range of bulk material applications.

Rotor rotary valve service repair Instandsetzung
Damaged or worn-out rotors from a rotary valve can be refurbished and repaired by us. The rotors are reassembled, and an ATEX inspection is carried out after the repair, complete with a test protocol. This ensures the longest possible and thus resource-efficient use of machine parts.

Round filter INFA-VAIO-JET AJV as bag filter for dedusting of bulk materials
The bag filter INFA-VARIO-JET AJV is especially suitable for dedusting pneumatic conveying processes of bulk materials. All parts in contact with the product are manufactured of stainless steel serially. Because of the round construction, the bag filter is applicable for overpressure / low pressure up to +/- 0.5 bar. But this filter series can be used generally for all cases where a product / dust / air mixture continuously arises over a long period of time. It is also suitable for de-dusting of mechanical transporting and manufacturing processes.

Round silos
We manufacture round silos made of stainless steel and normal steel from 5.73 m3 to 361.66 m3 in a standardized type series as a single silo or silo battery, planned with all accessories such as filling and discharge technology, mechanically or pneumatically. The substructures are constructed on a project-specific basis and calculated in a statically verifiable manner. Our silos are also available in custom-made versions as multi-chamber silos and in pressure shock-resistant versions. The variety of designs of silos and accessories is individually adapted to your needs with know-how.

RS30/40 Recycling: Four-shaft shredders for universal use recycling applications
Advantages of the RS30/40 Recycling The RS class shredders are characterised in particular by their high availability and process stability. In addition, they are functional in design and uniquely productive. A special advantage of the four-shaft shredder is the high quality of the output material, which is achieved due to the efficient material disintegration during the shredding process. The optimised piece sizes and homogeneity of the shredded material are ideal for downstream sorting processes and the extraction of valuable resources. The interchangeable perforated strainer permits the definition of granulate sizes depending on the application case. In general, each RS30 and RS40 shredder can be tailored to requirements, and is available either as a stand-alone solution or as a comprehensive solution. Low maintenance, with high safety standards Other advantages of the compact shredding machines: The low-speed four-shaft shredders are resistant to extraneous objects, and very low maintenance. Thanks to the pull-in mechanism, the machines do not need a hydraulic pusher system, which further reduces the need for maintenance. The low cutting shaft speed ensures low noise and dust pollution. Over and above this, the RS class shredders comply with high safety standards, which is of particular importance in the field of product destruction or the destruction of files and data. Overall, the types RS30 and RS40 are highly flexible and can be used in different recycling applications such as files, dashboards, automotive interior panels, bank notes, data, hard drives, films, plastic packaging, leather, metal chips, paper, plastic bottles, production waste, packaging materials and much more.

RS50/60/100: Four shaft shredder for industrial recycling applications
Maximum reliability for challenging applications Top-quality recycling for even the most extreme applications and materials from a premium manufacturer: The mature RS50, RS60 and RS100 shredders, which have been tried and tested under difficult conditions, are characterised by their outstanding reliability, their ability to handle unshreddables and a particularly wide application range - from electronic scrap and metals, through to plastics and data destruction. Further features are their rugged and resilient design, high availability and process stability, as well as low noise, easy maintenance and particle precision. Advantages of the RS50/60/100 As these machines are modular in concept, the speeds, torques, cutting unit apertures, cutters, perforated screens and sealing variants can be individually assembled for each industrial shredder depending on customer requirements. The rugged construction and the robust cutters make this high throughput shredder particularly attractive for multi-shift continuous operation and integration into existing plants. The middle-range RS class series is particularly effective in difficult recycling applications and in pre-shredding. In contrast to fast-running systems, four shaft shredders are especially resistant to foreign objects, meaning that if a cutting disc hits a foreign object, then the machine stops immediately. On the one hand, this prevents damage resulting to the shredder cutters. On the other, the reliable drive permits frequent reversing, which is particularly beneficial when shredding problematic materials. In addition, the manufacturer has integrated a perforated screen quick-change system as standard, which permits rapid and efficient changing of the screen and guarantees easy operation.
