Of course, rolls should be checked to ensure they have been installed on the correct stands. Once a year, the mill should be aligned. A mill alignment usually takes one or two days and is most often done by a professional. Every day, the mill operator should use a setup chart and follow all operating procedures.
Tworoll mill Tworoll mills are generally good dispersive mixers and, with the inter vention of the operator, good distributive mixers. The mixing process 1. tends to be slow, 2. is largely manual, and 3. can present problems related to health. As a result of these limitations, tworoll mills in the plastics industry tend

Do not restart the mill under load. Use caution when restarting the mill. 10. Once milling is completed the system will need to be shut down. Close the silo slide first to clear the drag, the surge bin and roller mill in sequence. 11. Lockout for any work on the mill is achieved by the isolator switch located on the control panel. HOUSEKEEPING 1.
The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the other one (friction). Therefore, shearing forces act on the rubber in the nip between the two rolls. In this way, the rubber is mixed. Structure of a mixing mill. A mixing mill consists of two rolls arranged in parallel ...
That is, for an open mill with [PHI]22" x 60", the batch weight should be 2 x 60 = 120 pounds ( kg) (in the same way, for a compound with specific gravity, that batch weight corresponds to liters). This method seems to me even more questionable than the one derived by Stalinsky. In any case, the open roll mill nominal load capacity ...
In modern rice mills, many adjustments ( rubber roll clearance, separator bed inclination, feed rates) are automated for maximum efficiency and ease of operation. The whitenerpolishers are provided with gauges that sense the current load on the motor drives which gives an indication of the operating pressure on the grain.
This standard specifies the methods of test and inspection for rubber roll for rice mill. Specifically, it shall be used to: verify the main dimensions, weight, and other technical data of the rubber roll submitted by the manufacturer/dealer; determine the performance of the rubber roll; and prepare a report on the results of the tests.

between the rolls, the thickness of the lead strips shall be measured at three separate positions with a micrometer to an accuracy of ±0,01 mm. The tolerance on roll clearance shall be ±10 % or 0,05 mm, whichever is the larger. The mill rolls shall have provision for circulation of heating or cooling media. Laboratory internal mixer
So, a good practice is to open your rubber calender at least inches ( mm) before starting to increase the roll temperature above ambient. Keeping the calender rolls turning during warmup and cooldown also eliminates the possibility of warping the rolls. Minimize calender stops.
