For this reason, Graham Engineering
offers rapid in-line color
change via its accumulator heads.
While many competitive heads can
take as much as 8 to 12 h to purge
from one color to another, Graham
heads can generally change from
one color to another in 30 to 60
min, using only simple hand tools.
After removing some bolts, the hydraulic
cylinders on the head are
used to lift the diverter and plunger
out of the head body. The diverter
plunger and head body can then be
cleaned using a brass scraper. When
finished, the diverter and plunger

a newly designed GMP-compliant
twin-screw extruder, supplied by a
continuous mass-controlled powder
dosing unit and a continuous liquid
dosing unit (Figure 2). The BCG
extruder offers a monoblock design
that features no dead spaces or connections,
which makes installation
and cleaning easy. The " real " torque
measurement - on each screw individually
- allows for tighter control
of the process, says Andreas
Altmeyer, head the service center at
L.B. Bohle.
Finding flexibility
Sometimes increased efficiency also
comes in the form of greater flexibility.
Handling a variety of materials
and frequent product changes
means there are often changeovers,
which amounts to a lot of downtime.
This is especially true when extruding
plastics, says David Schroeder,
president and CEO of Graham Engineering
(York, Pa.; www.grahamengineering.com).
" Downtime or
loss of production and material due
to changeover is expensive and time
consuming. Product quality can
also suffer, resulting in scrap, until
optimal production is achieved, "
explains Schroeder. " In addition,
equipment is a significant capital
investment. A single line or machine
