Overview
Batch mixing is generally carried out
using two specially designed blades inside a temperature controlled
chamber. It is most commonly used for compounding and mixing
of rubber formulations. Its most important commercial use is the
incorporation of carbon black and other additives into rubber
for the manufacture of automobile tires. Laboratory size batch
intensive mixers are extensively used for characterization of
materials and processes.
