The point where the mill becomes a centrifuge is called the "Critical Speed" and ball mills usually operate at 65 to 75 of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns.

Hard Rock Mining Gold and Silver Ore and processing it

In most gold ores the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive so it is widely used in precious metal ore processing. One stage rod mill grinding is therefore suitable for preparation of feed to gravimetric ore dressing methods certain flotation processes with slime problems and magnetic cobbing. Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least 1.4.

Rod mills how they functionMine Engineer

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition and broken and worn rods must be removed. In most gold ores the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive so it is widely used in precious metal ore processing.

Ball Mill Operating principles components Uses

Jul 05 2020 · e. Rotation speed of the cylinder. Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel ranging from 0.010 liters for planetary ball mills mixer mills or vibration ball mills to several 100 liters for horizontal rolling ball mills. The VibroKinetic Energy (VKE) Mill is designed to fill the need for a fine to ultrafine grinding mill which is both low cost and economical to operate.Optional features include air classification while dry grinding which greatly improves the efficiency of the mill. Wet grinding with hydrocyclone recycle for accurate sizing and use of vibratory table for concentration of ore values is also

Rod mills (see Fig. 17) follow the general dimensions of tube mills with diameters from 3 to 6 ft. and lengths from two to three times their diameter. They differ from ball mills in that steel rods 3 or 4 in. shorter than the mill length inside the liners are used as grinding media. Rod mills are often run on tires and rollers instead of trunnions or on one trunnion and one tire and set of The batch ball and rod mills require a drive roll to rotate the mill the proper grinding speed usually 60 - 75 of the critical speed for ball mills and 50 to 90 of critical speed for rod mills. The batch ball mill should be run between 56 RPM s and 70 RPM s. The batch rod mill should be run between 47 RPM s and 79 RPM s.
