Intensive Mixers

High speed/high pressure type mixers have been introduced to a wide range of fields such as the kneading of various rubbers, and various plastics.
After the Banbury mixer had been developed as a machine for the kneading of rubber compounds,
Nippon Roll pioneered in Japan, developing the first viable, domestically produced mixer. The Nippon Roll internal mixer was given the name Intensive Mixer.
For this machine to perform well under all kinds of harsh conditions, robustness is put first in the design and manufacturing of the Intensive Mixer.
Today, Nippon Roll Intensive Mixers are used not only for the kneading of all types of rubber but also in all fields of plastics processing. Their excellent performance has earned the machines a high degree of trust both in Japan and abroad.
We pay strict attention to after-sales service and maintenance. Each customer is a VIP as far as Nippon Roll is concerned.
