Waste screen

This screen uses specially designed screen decks for the waste sector. The maximized screen openings, a unique design of the openings and the combination with divergating bars result in an almost non-clogging screening, loosened material and high feed rates. C&D, WEEE or municipal waste – a broad variety of decks allow for efficient screening. This screen prepares the material for downstream treatment utilizing the optimized vibratory movement.

The IFE unbalanced shaft is a well-established and reliable drive for circular motion vibrating screens. The working torque can amount to 19000 kgcm, depending on type required. With the use of Premium Roller bearings combined within an oil bath lubrication the result is a highly reliable machine with a bearing lifetime that allow up to 80.000 hours of operation between bearing change outs.
The speed of the unbalanced shaft can be controlled either with a V-belt or infinitely variable using a frequency converter, resulting in a variable adjustment of the amplitude.

Installation elements such as compression springs, rubber buffers, isolating frames, etc. are selected according to the requirements. Most elements cannot be changed afterwards.

However, air springs, which are already known from vehicle technology (the so-called "shock absorbers"), can circumvent this restriction as they utilize the compressibility of air. Air springs are rubber bellows filled with compressed air, similar to a vehicle tire. Due to this, they can dampen vibrations and shocks very well. Added external compensating tanks enhance the damping effect so that dynamic forces emanating from the screening machine are reduced to a minimum. The robustness of the compression spring can of course not be achieved with rubber bellows.
