Rod Mill Design & Power Draw

The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).

Crushers Selection Guide: Types, Features, Applications

There are several types of industrial crushers available to industrial buyers. These types include: Cone or gyratory crushers insert feed via a cone-shape bowl and crush it with a spinning or gyrating head. HPGR (high pressure grinding rollers), roll/roller crushers, or mineral sizers use two large rollers or a roller and a flat surface. The ...

Rod Mill Design Calculations

When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.

Ball Mill VS Rod Mill: Difference & Selection

The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.

It is commonly made in sections so that it can …

Ball Mills vs Rod Mills

Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..
