Rubber compounding was performed on a tworoll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a threestage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was .
Jun 25, 2014· Some rolling mills are simply equipped with a smooth, flat roller while others have a combination roller. The combination roller offers a section of flat surface and a section with wire grooves. The wire grooves do not roll perfectly round wire, though; for that, you would need a full round rolling mill. The wire grooves roll mainly square wire.

The Stock Blender is an addon accessory mounted on top of an open tworoll mill. It aids in rubber blending by pulling the mix compound from the front roll of the mill and guiding it to the nip gap between the two mill rolls. Structurally, this machine assembly consists of a blender roll, a carriage.
Santec''s Two Roll Mixing Mills are widely used for mixing and kneading raw rubber, synthetic rubber, thermoplastics or EVA with chemicals into even materials. The even materials can be fed to calender, hot presses or other processing machinery for manufacturing rubber or plastic products.
This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and refeeding it into the nip until all the ingredients are added.

May 02, 2017· This mill consist two rollers arranged as shown in figure. Both the rollers rotate in opposite direction for desire movement of work piece. Work piece is feed between the rollers which apply a compressive force and tends to plastically deform work piece and convert it into desire shape.
Roller mills are industrial mills that, instead of using flat plates, uses cylindrical rollers to crush and grind material. The Williams Roller Mills are designed to provide years of reliable, consistent, and efficient operation, but the reason why Williams is one of the leading roller mill manufacturers is their ease of use and maintenance.
