![]() ![]() They can be configured with electronic controls for the dwell time. The machine is driven by the well proven JOEST Unbalanced Drives. Configurations with machine-mounted or stationary hoods, as well as different standard- and stainless-steel options are available.įor easy maintenance, service flaps are equipped with gas pressure springs and quick-release levers. The dryer can be operated with fresh air or (partial-)air recirculation. With a grain size of up to 25 mm and a throughput of 5 tons per hour, the product moisture can be reduced from 10% to 0,2%.įurthermore, the separation into multiple zones for drying and downstream cooling is possible. Different drying results are achievable, depending on the feed conditions. Processing air temperature for plastics is typically around 120 ☌ and can be increased to 400☌ in the standard version. This results in an even processing and drying performance. The special design and thermal isolation of the air distribution chamber support an optimized air flow regulation. Various energy sources can be used to heat the processing air. The product is conveyed through the dryer by a micro-throwing motion, whilst hot air travels through the material stream. This way the product is in direct contact with the heat transferring medium. ![]() The JOEST Vibrating Fluidized Bed Dryer dries materials such as PET-Flakes using convection. Special design features can be added, depending on your application. A special blow-through filter system is included in the design, enabling the machine to stand autonomously. ![]() The Zig-Zag Separator is typically operated with partial air recirculation. Maintenance flaps are included for easy service and cleaning. The sifting channel can be designed with 4 to 15 separation steps, depending on the application. Heavy particles fall through the sifting channel and are discharged at the base of the machine. Here they are discharged by a cellular wheel air lock. Inside of the sifting channel, lightweight particles are conveyed upwards through a system of pipes into the cyclone. Placing the fan on top of the cyclone ensures optimal air circulation and a compact form factor. A radial fan provides the required airflow which enters at the base of the machine and travels to the top. Unlike a cellular wheel, the feeder achieves an even product stream, reducing susceptibility. The material is fed into the Zig-Zag shaped sifter channel by a special vibrating feeder. Due to its high separating precision, it is often used in challenging sorting applications. The JOEST Zig-Zag Separator separates light-weight materials from heavy ones using the multiple crossflow sifting process. In addition to wear protection, anti-stick coatings, electronic machine monitoring and amplitude control, we offer a variety of individual options and configurations to meet your demands. The drive system of the Flip-Flow Screen is available with grease or oil lubrication. Typical separation steps are around 40 mm.įor the OSCILLA Classic, the decline angle can be reduced to a minimum of 10 degrees. Even if the machine was overflowing with material, it would be capable of clearing itself. The overlay enhances material flow by exerting additional acceleration forces on the product. The circular motion of the base frame excites the internal frame, creating an overlay of oscillations. The newly designed Vibroblocks combined with aluminum cross bars enable larger oscillation amplitudes and acceleration rates than conventional Flip-Flow Screens. The relative motion of the frames exerts and releases tension on the screens, resulting in acceleration rates of up to 50 G on the screen deck. Flexible polyurethane screens are attached to both frames with one side each. The internal screen frame performs a relative motion in reaction to the directly excited external frame. The Flip-Flow Screen OSCILLA Classic is the foundation of the entire OSCILLA Family, which are all based on a resonance system.
