Method of Operation
There are various
ways to dose the feed material into the mill
according to the requirements, such as vibratory
feeder, feed screw or a rotary air lock.
The rotor is aligned vertically and together
with the stator, they form a cone shaped
grinding chamber
This geometrical
arrangement allows the grinding gap to be easily
set by raising or lowering the stator.
Size reduction or
conditioning occurs between the impact edge of
the rotor and the wear resistant grinding path.
The degree of fineness or conditioning is
controlled by the grinding gap, circumferential
speed of the impact edge of the rotor, volume of
air, rotor type as well as the type if grinding
path, therefore resulting in preferred
combinations for pulverizing, mixing, dry
grinding and coating.
Very often there is
no requirement for a sifter to control the upper
particle size. A blower suctions the
product out of the mill and onto either a
cyclone or filter separator.
The PALLMANN
ConoMillTM, type PLK is available in
a pressure shock resistant design up to 10 bar
for dust explosive materials.
The rotors and
grinding paths can be made of weare resistant
ceramic specially designed for abrasive hard
materials and for an iron free grinding in the
food industry. Also for food or chemical
industries, the mill is available in stainless
steel and/or GMP compliant versions. |
