A two high rolling mill where the direction of rotation of rolls can be reversed to allow for work to pass through from either side. Besides flat rolling and shape rolling, identify some additional bulk forming processes that use rolls
HEXA PLAST Two Roll Mill with fixed speed and friction is laid out for constant working conditions. The machine is available with roll diameters of 150 mm. (as per requirement). The rolls are driven by a geared AC Motor. The rear roll is driven by spur gears for a constant friction.
A laboratory two-roll mill is used to hand-process plastics and the like. It looks like an old fashioned "wringer" from a washing machine mounted horizontally, but it isn't. The rolls counter-rotate, to be sure, but they do so at different rates to create a shearing action in the trough formed between them.
Rolling is the process of reducing the thickness or changing the cross section . thickness, mm (in).R = roll radius in mm and (α) = bite angle in degree. Draft is . A 300-mm-wide strip 25-mm thick is fed through a rolling mill with two powered rolls each of radius = 250 mm. The work thickness is to be reduced to 22 mm
In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls several times. This type is used in pluming and slabing mills and for roughing work in plate, rail, structural and other mills.
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.
Roller mill is a form of compression mill that uses a single, double or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials.
