The JOEST AirVibe 2 – Vibratory Air Separator provides a coarse separation of inhomogeneous, mostly dry recycling material with a maximum particle size of 300 mm (12 inches). The material mix is separated by different densities, shapes and surface characteristics into the desired product groups.
The unique combination of multistage ballistic and cross flow air separation ensures a very high degree of separation. This opens up new ways in the processing and separation in the recycling industry.
PRINCIPLE OF OPERATION:
The AirVibe 2 is vibrating with a linear stroke using 2 unbalanced motors. This motion is important for the transport, fluidization and even distribution of the infeed material. An adjustable air knife, positioned at the end of the impact area blows through the material stream. Light material particles like paper, plastic and card board are blown into the expansion room of the AirVibe 2 and discharged at the light material fraction of the end of the AirVibe 2.
The medium weight particles which were not separated in the first separation stage based on size and shape hit an adjustable separation plate. Especially light particles with a larger surface area and those with a higher grip will be moved over the separation plate due to the linear stoke of the machine and
added to the light material fraction.
Round, rolling particles and those with a smooth surface like stones and glass are sliding down the separation plate and added to the heavy material fraction.
A second air knife under the impact area is blowing directly onto the separation plate. This way light, rolling particles like plastic bottles can be separated and distracted with the light particles. The integrated chain curtain separator allows a much more compact machine design due to a smaller expansion chamber.
For surface wet materials a special design with a separation drum with a scraper instead of a plate, have proven to be very effective and low maintenance. The AirVibe 2 has many possibilities for adjustments according to the inhomogeneous and very different and damaging materials to be separated.
This includes the adjustment of the separation plates and air knifes, impact area as well as the vibration parameters of the machine. The max. capacity of the AirVibe 2 is about 15t/h.
