is used for difficult to grind and
disperse materials and for the ultimate in micron size and
quality. the main advantage of the “Q” series is the very narrow
particle size distribution that can be achieved.
Large quantities of material can be ground with a smaller
investment of grinding media and attritor equipment. the slurry
can be continuously monitored. additional ingredients can be
added to the premix tank at any time during the grinding, with
sensitive materials being added near the end of the grinding
cycle. excellent temperature control is possible, since the slurry
spends only 20-30 seconds in the grinding chamber and has
plenty of time to be stabilized in the holding tank.
“Q” series attritors are available in sizes ranging from the
laboratory size Q-2 model up to the large-scale production
model Q-100. For very large production, several Q-100 attritors
can be hooked up to a single holding tank.
Circulation attritors designated as “QL” include specially
configured arms and disks for special applications and
increased performance.
a variety of accessories meeting different conditions, from
cover seals for a totally enclosed system to metal-free systems,
are available.

Special Options
Tank Linings
—special linings for metal-free grinding are
available. Choose from ceramic (alumina) tiles, food-grade
rubber or polyurethane.
Arm Sleeves
—to accommodate metal-free systems, shaft
arms may be sleeved with plastic, tungsten carbide, or
zirconium oxide.
—can be equipped with a floating shaft seal to
minimize solvent loss, or can be equipped with a meCo
shaft seal for grinding under inert gases, complete with a
product charging port, gas inlet and outlet.
Torque Meter
—for monitoring precise energy consumption
which is used for determining grinding time and for added
quality control.
Stationary Arms
—for high viscosity materials
