The rod mill and autogenous or semi-autogenous mills are described in subsequent chapters. 7.2. Design of Tubular Mills. ... A grate discharge mill of dimensions 4.12 m × 3.96 m was loaded to 40% of its volume with gold ore. The mill drew 10.95 kW power per tonne of balls.

A wet rod mill was loaded to 45% of its volume with a charge consisting of a gold ore and steel rods. The rods diameter was 70 mm. The mill had an inner diameter of 1980 mm and was rotated at 21 rpm with a rod load of 23.8 t. The rock volume was 0.4 times the rod volume after taking into account the porosity of the bed. Estimate. 1.

Grind coarse feed material with a reliable Rod Mill that won't over-grind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and …

The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.

It is featured with high crushing ratio, good reliability, strong adaptability and large capacity.They are applied for the primary ore grinding for the mining industry or the high standard sand making for the aggregate industry. Rod Mill for sand manufacturing.

This research is done to find the particle size distribution of gold ore after it has been treated through the comminution process in a rod mill with various number of rod and rotational...

This research is done to find the particle size distribution of gold ore after it has been treated through the comminution process in a rod mill with various number of rod and rotational speed ...

This will mean that there is more ore than surface area of the Rods. This excess amount of un-ground ore will cause the rods to lift and separate, spoiling the grinding action of the entire mill. The amount of water that the mill requires to grind the ore, properly, varies depending upon the type of mineral and the characteristics of the Native ...

The Ukumba Gold Rod Mill is designed to suit multiple coarse ore grinding applications. Available in multiple sizes ranging from 5tph to 20tph. The rod mill is best suited after a secondary crushing stage and can be supplied as a wet or dry process.

These mills are required to prepare ball mill feed. With pebble milling the pebble portion of the product does not go thru the rod mill thus the rod mill feed rate is reduced by 30 metric tonnes per hour (6% of 500 metric tonnes per hour). 2062/500 x 470 = 1938 HP. 1938 ÷ 2 = 962 HP

Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (i.e., increased feed water) at least down to the range of 45 to 50% solids by volume. The higher the discharge % solids in the plant rod mill, the better the candidate for feed water addition rate test work.
