Mills for Laboratory and Pilot Plants
Universal Mill, type PXL
& PPXL
Size reduction from coarse to superfine grinding down to
minus 20 micron and product hardness up to 3 according
to the Mohs scale, such as chemicals, pharmaceuticals,
food, annual plants, leaves, roots, minerals etc.
Method of Operation
The size of the
in-feed material has to be smaller than 6 mm
(¼"). Typical particle sizes that can be
achieved are in the range of 2000 to 100 micron
(10 to 170 mesh).
Material is put into
a feed hopper. The vibratory feeder is metering
the material into the universal mill. Size
reduction is performed between stationary and
rotating grinding inserts. The particle size of
the end product can be adjusted by the speed of
the rotor, the mesh size of the screens and the
type of grinding inserts chosen. A wide variety
of different grinding inserts is available.
Materials can be pulverized, fiberized,
homogenized and mixed. Product discharge is down
to below into a collecting bin. Process air is
cleaned in a dust collector.
The PPXL is a
counter-rotating
mill used for pulverizing greasy, sticky and
moist materials under ambient temperature or for
cryogenic grinding. |
