Low Built Base granulators
for sheet and film
Size reduction equipment specialist
Rapid has launched the LBB 300
series, a granulator with a very low
height for handling sheet and film
scrap. The new unit (LBB stands for
Low Built Base) is intended
principally for use in-line with a
thermoforming unit, where its very
low height allows it to be located
directly under the output conveyor,
saving valuable floor space.
T
he LBB 300 series, which appeared in prototype form at K
2013 in Düsseldorf two years ago, made its official com-
mercial debut at the Fakuma show in Friedrichshafen, Ger-
many, on October 13-17. It is available worldwide.Height of
the LBB 300 series is just 600 mm (excluding feeder) and it is
available in three widths: 900, 1200 and 1500 mm. The unit
can be equipped with a rollfeed unit synchronized to the ther-
moforming line speed, or with a simple tray that collects skele-
tal frames as they fall from the line.The modular granulator
can also be configured to fit directly under a shredder to pro-
vide final size reduction, without the need for the conveyor
belt used in common practice for connecting the two units.
Rapid offers the LBB granulator in versions with various types
of rotors and hoppers, depending on the application.The very
compact design of the LBB 300 series means that it takes up
very little extra space on the production floor. Depending on
model, width is between 2000 and 2300 mm, and depth is
700 mm. It is designed to handle film and sheet up to 8 mm
thickness, depending on material.”We are really delighted
with our latest addition to the extensive Rapid range of gran-
ulator solutions,” says Bengt Rimark, Sales and Marketing Di-
rector at Rapid. “The new LBB 300 series represents what we
are all about at Rapid - innovative, flexible and highly-efficient
space and cost beneficial granulator systems that meet our
customers’ needs.”The LBB 300 series uses a true scissors cut-
ting action to provide clean and precise cutting of sheet and
film, and high quality regrind. The rotor on all models is 300
mm in diameter, fitted with six, eight or ten blades depending
on model size. The two smaller units have six fixed knives,
while the largest has nine. Units can be fitted with motors
rated at between 7.5 and 30 kW. Maximum throughput ca-
pacities range from 800 to 1200 kg/h. Output can be trans-
ported via a vacuum conveyor straight back to the production
line for reprocessing.All units are fitted with a rotor stand-still
guard for operator safety. The two larger units both feature
split screens and split screen boxes for extra ease of service
and maintenance. The equipment is mounted on a solid stand
with castors for ease of movement when required. Basic units
weigh between 1200 and 1500 kg, depending on size.
