AMIT 135: Lesson 8 Rod Mills – Mining Mill Operator Training

Reduction ratio = 2 – 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range; Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = 6.25 tons/m3; In wet grinding, the solids concentration 1s typically 60% – 75% by mass.

Rolling (metalworking) - Wikipedia

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its

Roller mills: Precisely reducing ... - Commercial Grinding

500 rpm, the roll speed ratio is 2:1 (1,000/500). More shear — and thus a larger roll speed ratio — is required to crush less friable particles. Running the rolls at the ideal roll speed ratio will achieve the desired shearing effect as the material passes through the nip point; the higher the shear, the more tearing the crushed particle
