Another way of polymer processing is fine powder mixing and the use of monomers for polymerization. In the fine powder mixing method, the particulate matters and polymers are processed through the ball milling machines (e.g., cryogenic ball milling and vibratory ball milling) for processing of polymers (Krycer and Hersey, 1980).
The extruder accepts warm rubber strip from a 2- roll mill. The screw conveys the compound to the die and force through the die under pressure. The hot feed extruders remain the first economical choice for straining of rubber compounds and as a feeder machine for Rubber Calenders.
(1836) two roll mill [5]. The two roll mill was widely manufactured by machinery companies in the USA and Europe. It became the primary method of preparing compounds in the (natural) rubber industry well into the second decade of the twentieth century [29, 30]. Single-screw extruders seem to have been introduced in the 1870s, but were
