Abstract
A production line (200) for performing multi-pass mixing sequences of rubber mixtures has at least one first mixing line (200A) that produces a masterbatch and at least one second line (200B) that performs a final mixing process during a final pass of a multi-pass rubber mixing sequence. A mixing process produces a variety of rubber mixtures in a production line of the type disclosed.
Claims10
A rubber mixture production line for performing multi-pass mixing sequences, the production line comprising:
- at least a first mixing line comprising:
- at least one internal mixer that performs a masterbatch manufacturing process;
- a hot mixing line disposed downstream of the internal mixer and comprising at least one twin-screw mixing machine that performs a mixing process of the rubber mixture exiting the internal mixer;
- a transfer belt installation disposed downstream of the hot mixing line for controlling a temperature and an addition of water in a rubber mixture exiting the hot mixing line;
- a batch-off installation disposed downstream of the transfer belt installation for performing an anti-sticking and cooling process of the rubber mixture exiting the transfer belt installation;
- and
- an end-of-line installation disposed downstream of the batch-off installation that performs one or more end-of-line processes on the rubber mixture;
- and
- at least one second mixing line comprising:
- a twin-screw mixing machine that performs a mixing process of the rubber mixture exiting the first line;
- a transfer belt installation disposed downstream of the twin-screw mixing machine for controlling a temperature and an addition of water in a rubber mixture exiting the twin-screw mixing machine;
- a cold mixing line disposed downstream of the transfer belt installation and comprising at least one twin-screw mixing machine that performs a mixing process of the rubber mixture exiting the transfer belt installation;
- a batch-off installation disposed downstream of the cold mixing line that performs an anti-sticking and cooling process of the rubber mixture leaving the cold mixing line;
- and
- an end-of-line installation disposed downstream of the batch-off installation that performs one or more end-of-line processes of the rubber mixture,
- wherein the second line performs a final mixing process during a last pass of a multi-pass rubber mixing sequence.
