QUADRO Comil technology converts motor energy more efficiently into size reduction forces, leading industry milling performance standards in powder grinding and pulverizing. Patented and proprietary screen and impeller designs ensure consistent energy transference providing previously unattainable narrow PSD spans for sub 400 micron target range. Furthermore, the H20 unmatched controllability to shift PSD targets, guarantees higher on-spec returns.

Milling

2. Quadro H20 Comil
Converts motor energy more efficiently into size reduction forces
to lead industry milling performance standards in powder
grinding and pulverizing.

3. Quadro H20 Comil
Unique Benefits – Unparalleled conical milling size
reduction and performance:
• Typical particle size distribution in 250 < d97 < 400 µm
• Ability to control & shift PSD targets
• Higher yields than conventional mills of equivalent
foot print.
Benefits

4. Quadro H20 Comil
Unique Benefits – Narrow particle size distributions
(less waste / less rework) than traditional milling:
• Improves on-target milling by 30-70%
• Reduced need for Screening over/ under sized
particles
Traditional Conical Mill PSD Curves H20 Unimodal & Narrower PSDs
RPM, screen hole/
configuration & impeller
profiles are a few of the
variables that can be used to
shift and better control PSD
targets
Benefits

5. Quadro H20 Comil
Unique Benefits – Contained milling (< 1µg/m3 OEL):
• Compact in-line configuration (standard tri-clamp
connections)
• Quick/ easy access to ‘product contact’
components reduces cleaning and changeover
times
Benefits

7. Quadro H20 Comil
Operating Principle
 Conical screen chamber designed to
supply vortex flow pattern to in‐feed
material by means of a rotating impeller.
 As product travels into the ‘action zone’
by continuous centrifugal acceleration, it
passes through PSD target-specific
screen hole openings
 As a result, material is sheared through
the screen at optimum tangential
velocities, creating uniform size
reduction rates and producing narrow,
consistent and repeatable particle size
distributions.
