- Raw material containing up to 80 % moisture
is dropped into the throat of the KDS Micronex™ where
it passes through an air-lock gate valve that eliminates
blow-back and dust.
- The material enters the torus rotor chamber
where it falls onto spinning chains and is subject to enormous
centrifugal accelerations. The chains spin with a tip speed
of about 400 mph. The material is “fractured”
as it impacts repetitively with the chains and the strike
plates on the sides of the torus. Liquid water is squeezed
out of the material due to the compressive action of the
impacts. Heat created from the kinetic energy of the impacts
evaporates some of the moisture in the material. When appropriate
particle size reduction is achieved, air flow in the torus
lifts the particles upwards towards the classifier. Because
some of the water removal happens due to mechanical forces,
less energy is consumed than in thermal dryers – usually,
only 500 to 900 BTU per pound of water removed - less than
the latent heat of water! No heat input is used - only electricity.
- The classifier sorts the “fractured”
material and can be adjusted for the desired particle size.
Selected particle sizes pass through the classifier and
larger particles are forced back to the torus to repeat
the impact process.
- Finished material is pneumatically conveyed
out of the machine into the cyclone where the dry powdered
finished material falls through the bottom air-lock gate
valve to be packaged or placed in a bulk container.
- Air containing water vapor and water
droplets leaves the top of the cyclone back into the blower
and then on to the grinding chamber. Water vapor and droplets
leave the chamber through the vapor vents.
- The floor of the torus, i.e., the clam,
opens easily for maintenance. Replacing the bars or chains
can be accomplished in ten minutes or less.
