Pneumatic 2 Dimensional High Speed Bonding Mixer

In order to produce bonded metallic powder coatings, a process is required that will heat
the powder to its softening point, usually 45-550C. The heat input will be achieved by a
combination of mechanical energy from high speed mixing tools, from a hot water jacketed
mixer, or a combination of the two. The mixing speed will be variable, as generally high
speed is required to heat up the powder within a reasonable time scale, but low speed is
preferable for mixing in the pigment and achieving the adhesion. Low speed minimises
damage to the pigment structure. When bonding is achieved, it is important to cool the mix
as quickly as possible to avoid excessive agglomeration and lump formation. In the
extreme, bonded batches can completely solidify in the bonding mixer if overheated or not
cooled fast enough. Cooling will be achieved either by introducing chilled water into the
bonding mixer jacket, or cooling in a separate cooler mixer
