B＝T÷（ D×R×M×11305） Calculated based on the right of formula: B = T÷ (D x R x M x 11305) B: The rolls width T: indicates the total output D: indicates the diameter of the rolls R: was broken crushing fineness M: the material gravity (11305): said the calculation of the coefficient Selection of the roll surface 1, a crushing particle size of less than 3 mm when the choice flat roll surface. 2, the broken particle size greater than 3 mm optional cone welding roller surface. 3 require crushing the finished material after the particulate, powdered small, selected gear rolls. A require crushing the finished feed size is greater than the the 30mm selection wolf tooth surface. B, requiring broken after the finished feed size less than 30mm, larger than 8mm selection occlusal tooth surface.
