Zig-Zag Air Classifier - Plastic Recycling Machines

The zig-zag air classifier can effectively remove these containments as they are lighter in weight. WORKING PRINCIPLE. Air classifiers use air as the medium to separate lighter materials from heavier ones. A mixed material stream is dropped into a sorting chamber containing a column of raising air. As the material mixes and is blown upwards, lighter objects are blown through a top exit while ...

Air Classifier/Zigzag Separation for Plastics - Recycling ...

Air classifier for plastics uses air as a medium to separate light objects from heavier plastics. A strong airflow comes from the bottom to the top, while a stream of materials falls from the top. Plastic flakes and granules then go through a zigzag channel. In the meantime, lighter materials like labels and dust are blown upward and collected in filter bags.

The separation performance and capacity of zigzag air ...

Zigzag air classification is a separation process in which particles are classified mainly according to their falling behaviour in an air flow. Figure l.l.a shows a zigzag air classifier. The channel consists of rectangular sections joined together at an angle ~ to create a zigzag shape. A dispersion of particles is fed to this channel. The aero­ dynamically "light" particles are carried to ...

01/03/2017  The zigzag air classifier consists of a number of sections with a rectangular cross section connected to each other at angle of 120°, connected to create a zigzag shaped channel. The heavier (larger and coarser) particles are classified according to their specific weight in the zigzag channel (guided by the influence of the gravitational force) while the air stream is flowing upwards.

Zig-zag air classifier B+B Anlagenbau

Zig-zag air classifier. A Zig-zag air classifier divides a mixed material stream into two homogeneous streams. The upward vacuum extraction ensures the lighter micronized materials to blow up to exit the sorting chamber separately, leaving the heavier materials to exit at the bottom. For a higher quality performance, B+B builds classifiers by placing multiple units in a circular arrangement ...

CLASSIFIERS

In the zig-zag classifier, vortex formation leads to the acceleration of the main flow owing to a reduction of the effective tube cross-section. Fines follow the main gas stream and coarse particles travel to the wall, and fall back against the main gas flow. In this design, the sharpness of cut is low at each stage (zig-zag), but a required cut size is generally achievable even at high ...

Air classifier - Wikipedia

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air. Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air ...
