Operation To produce the rubber used in tires, hoses, shoes and many other applications, the rubber first has to be created using a two roll rubber mill. A rubber mill consists of two horizontally opposed stainless steel rolls that rotate in opposite directions, at different speeds. The rolls rotate towards each other, one faster than the other.

1. Two High Rolling Mills It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll is adjustable. The rolls rotate in opposite directions and are driven by electrical motors.

Working principle of the duo coldmill. As a circular rolling mill, the duo coldmill has two key points. One is the "front dead point," which is the limit position where the frame moves closer to the production tube. The other one is the "rear dead point," which is the limit position where the frame moves closer to the tube blank.

The mill has 2 rolls. The roll axes are horizontal and parallel to each other. The rolls form a pair with the opposite direction of rotation. The rolls are heated with steam or oil. For the heating scheme, refer to the calender rolls. A frequencycontrolled electric motor rotates the rolls on rolling bearings. Fourrow bearing saves 1015% of ...

The principle of the roller mill is breaking and crushing actions are achieved mechanically with the application of pressure. Stress is applied by rotating heavy corrugated wheels (mullers or rollers). The oil is squeezed out from the solid material. Construction The construction of a roller mill is shown in Figure.

Two Roll Mill is one of the important equipment in plastic processing, It can make the raw materials and additives mixing well. The plasticizing with the opening mill is mainly through the shear and extrusion effect of two relatively rotating rollers on the rubber material, so that the original macromolecular chain of the rubber material is broken, so that the original elasticity of the rubber ...
