We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
The ball/rod mill model: TA-12000 RAB cylinder is made of hardened alloy and chromium steel. It is resistant to corrosive pulps and sulfur minerals.

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
Referring to Table VI the L/D can be between 1.75 and 2.0 or even greater. Referring to Table VII a 3.05 meter (10 foot) by 3.05 meter (10 foot) overflow ball mill with a 40 percent by mill volume ball charge, new liners and 50 mm (2″) balls draws 491 HP. Using equation 5 there will be a loss of 0.55 Kw (0.74 Hp) per metric tonnes of balls.
Rod mills are tumbling mills that use steel rods as grinding media. They are commonly used to grind ore and other materials to sizes between 300mm to 0.1mm. Key features include rods that occupy 30-40% of the mill volume and tumble in a cascading pattern at 50-65% of critical speed. Rod mills provide a controlled size reduction with minimal fines and are often run in open …
Ball mills are used to obtain a product size below 150 microns. With the rotation of the mill, collision and attrition forces grind down the material in the mill chamber. The balls act as the grinding media, where contact points are created with each other and the material is either crushed or ground.
The Cayeli concentrator was commissioned in 1994, with a design capacity of 600 000 tonnes/year. The grinding circuit was a classical rod mill/ball mill combination. The rod mill was converted to a primary ball mill in May 1997. The reasons for conversion were to use mill power more efficiently and eliminate feed interruptions during rod charging.
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 …
