01/03/2010 · For open roll mills, with roll diameter equal or higher than 20 inches, the batch weight, in pounds, is equal to twice the roll length in inches. 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 .
