Sieving Technology, Ultrasonic Supported
Roop Telsonic Ultrasonix offers Ultrasonic Supported Sieving Technology. Conventional sieving technology is based on a vibrational/wave motion of the sieve. This action is responsible for the sieve throughput as well as the separation of oversized material. In addition to the conventional method, Sonoscreen ultrasonic supported sieving technology evenly transmits as oscillating motion, in the micron range, onto the screen surface. This feature reduces friction between the sieve mesh and bulk material. Depending upon the particle structure this reduction can result in a significant increase in throughput volume. Screen blinding and clogging are also reduced due to the cleaning effect the oscillating motion has on the sieve mesh. A consistent efficient production process is guaranteed while simultaneously reducing the related maintenance costs to a minimum. Sonoscreen can be applied to both wet and dry sieving applications. Sonoscreen can be built into or retrofitted to all existing commercial sieving equipment. System components include: ultrasonic generator; ultrasonic sieve resonator; and HF-electrical connection with housing and plug, HF-connector cable. The Sonoscreen system is suitable for various frame shapes and sizes. Special systems that meet the specifications of the pharmaceutical and other special applications are also available. Advantages: a significant increase in throughput volume is possible (3-30 times depending on material and size of particle); considerable decrease of sieve screen blinding and clogging results in a consistent throughput volume; patented ring resonators produce an even distribution of mechanical oscillations; even for larger sieving frame sizes, the system has a low power consumption of approximately 60 W/m2 of screen area; low, constant operating temperature without localized heat zones; rigid, explosion-proof, waterproof, stainless steel design; long sieve life-span, will not degrade the sieve screen; short pay-back period due to incomparable cost effectiveness; mechanical cleaning or auxiliary installations can be eliminated; and maintenance-free operation, option of continuous or pulse vibration with adjustable amplitude.
