PerMix Fluidized Zone Mixer

The PerMix PFB series Fluidized Bed Mixer / Twin Shaft Paddle Mixer Non-gravity Mixerconsists of paddles with special angles that are mounted on twin shafts in a ‘W’ shaped trough. During operation, the two shafts are rotating in opposite directions.

The paddles sweep the entire bottom of both troughs, and materials are lifted floating between the two shafts (as zero-gravity zone) by the centrifugal force generated by the paddles. At this weightless zone, mixing of materials of different density is easy and fast because material particle can move freely and randomly, regardless of particle size and density. This brings a rapid and highly homogenous mixing.

1. Very fast mixing to supply a typical mixing time from 10 seconds to only 1 minute
2. Free particle movement
3.  Minimal heat and low shear for shear and heat sensitive materials (Due to the fact that low friction without shear in this non-gravity zone is generated, this makes the PerMix PFB series Fluidized Bed Mixer / Twin Shaft Paddle Mixer an ideal machine for fragile products that can’t tolerate rough handling, even flakes or spray dried bodies remaining intact after mixing.)
4. Easy cleaning and hygienic design with minimal blind corners
5. Low maintenance
6. Big bomb bay door for fast discharging & reduced segregation
7. Liquid addition by spray balls, nozzles, or dripping pipes
8. Leading edges of the ribbons can be coated by Tungsten Carbide for very abrasive materials.
9. Intensive choppers to break lumps
10. Various drive system (single motor/gearbox with chain; dual motor/gearbox, single motor with dual gearbox)

The PerMix Single Shaft Fluidized Bed Mixer, just like the Twin Shaft Paddle Mixer, is a fast mixer with high efficiency,  and low/no shear, which can also be known as Fluidizing Mixer, Fluidized Zone Mixer, Non-gravity Mixer or Zero-gravity Mixer.

The Fluidized Bed Mixer / Single & Twin Shaft Paddle Mixer is applied to prepare a homogeneous mixture despite of particle size, shape and density. When the small amount of powder additives or liquid is required to be added into the bulk material, Fluidized Bed Mixer / Single or Twin Shaft Paddle Mixers are able to achieve fast and precision mixing with high capacity.

The PerMix PFB & PFBS series Fluidized Bed Mixer / Signle or Twin Shaft Paddle Mixer Non-gravity Mixer consists of paddles with special angles that are mounted on shafts in a ‘U’ or ‘W’ shaped trough.

During operation, the shafts are rotating at high speeds, and in the Dual Shaft units, spin in opposite directions. The paddles sweep the entire bottom of both the trough, and materials are lifted floating between the shafts (as zero-gravity zone) by the centrifugal force generated by the paddles.

At this weightless zone, mixing of materials of different density is easy and fast because material particle can move freely and randomly, regardless of particle size and density. This brings a rapid and highly homogenous mixing.
