Aug 01, 1994· Three times longer than conventional roll mills, the Ross Condux units have a 7.5:1 L/D. As in a standard batch roll mill, each roll runs at a different speed and temperature, causing the material to form only around the front roll. An adjustable roll gap--from 0.5 to 5 mm--controls shear rate.

The invention provides an online predication method for Mooney viscosity of a rubber compound of a rubber open mill. According to the online predication method, the Mooney viscosity of the rubber compound is predicated in a predicted mixing process by using various process parameters of rubber materials with different formulas, which are detected in the rubber mixing process by the open mill ...

EFFECT OF TEMPERATURE ON RHEOLOGICAL PROPERTIES …

Rubber mills have two large horizontally opposed, closely spaced steel cylinders, up to 3 metres (10 feet) long, that are rotated slowly in opposite directions and at somewhat different speeds. Rubber is sheared and softened in the gap between the paddles and wall of the Banbury mixer and in the gap between the two cylinders in the roll mill.
