Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage 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 added to the rubber compound in the second stage.
Nylon 6/6 Commercial Grades & Properties. One of the most common industrial plastics used today is Nylon.

To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and ...
To improve materials characteristics of the coiler roll for hot strip mill, we have carried out the material development by the CPC production technique. Also, we have developed the pinch roll which the thermal load is higher than the coiler roll. In the pinch roll, the high tempetature hardness characteristics of the roll surface is important.
There are two material grades on offer depending on application. Feroform F57 operates over 100 °C, and Feroform T14 under 100 °C. The unique blend of finely-woven high-performance fibres builds an extremely tough, smooth, and resilient roll. Our rolls have already been successfully used by many leading manufacturers around the world.
An apparatus for carrying out a web delivery method is designed so that a web is delivered from a freely rotatable web roll to be supplied to a cigarette manufacturing machine as a pulling roller rotates. This apparatus has a powder brake for applying a braking force to the web roll, a rotary encoder for detecting the number of revolutions of the web roll, a timing sensor for detecting …
The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction. The material is rolled both in forward and return in three high rolling mills.
Cogging mill 2,2-2,7; Section rolling mills 1,6-2,5; Plate mills 2,0-2,8; 4-hi mills a) 3-5 (for work rolls); b) 0,9-2,5 (for back up rolls). Roll neck length usually equals to roll diameter. Diameter of roll necks with antifriction and friction (close type) bearings shall be in accordance with design.

Roll mills are also used for warming up materials for calendering or extrusion. In such cases the warm material is cut into strips that are fed into the calender or extruder often continuously. Another application of roll mills is to cool materials discharged from an internal batch mixer in a form of large lumps (see Section 4.2.3.1.2 ).

Further, the resultant mill roll was slit into 400 mm in width and 2000 m in length, and winded up on 3 inch paper tube to give two polyamide based mixed resin laminated film rolls (slit rolls). Then, using the two slit rolls thus obtained (namely, obtained from the same mill roll), the characteristics were evaluated in the following methods.
