pgm rod and ball mills. Jun 01, 2009 For conventional tumbling mills (rod, ball, and pebble mills), it has been found that models using a cumulative breakage rate function can easily be fitted to pilot or plant data and appear to be adequate for evaluating competing circuits (Hinde and King, 1978, Finch and RamirezCastro, 1980, Laplante et al ...
pgm rod and ball mills Know More. pgm rod and ball mills, IsaMill Wikipedia, the free encyclopedia The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills such as ball mills and rod mills Stirred mills often consist of stirrers, ....
pgm rod and ball mills. The rod mill usually uses 50100mm diameter steel rod as grinding medium while the ball mill uses steel ball as grinding medium The length of steel rod is 2550mm shorter than the cylinder and it is usually made of high carbon steel with carbon content of 08 1 the loading capacity of rod is about 35 45 of the ...
Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...

Advantages of Ball Mills 1. It produces very fine powder (particle size less than or equal to 10 microns). 2. It is suitable for milling toxic materials since it can be used in a completely enclosed form. 3. Has a wide application. 4. It can be used for continuous operation. 5. It is used in milling highly abrasive materials.

ROD MILLS. Capacity: t/h. Discharging Size: mm. Rod Load: 894 t. Customization: support. Material: various kinds of ores, like marble, pebble, granite, etc. SEND INQUIRY. GET QUOTATION. Rod mill is a commonly used grinding machine, which is named after the steel rod (grinding media) loaded in the cylinder.
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.

The output size of the grinding material in the ball grinding mill is generally between, and that of the rod mill is between Ball mill VS rod millcharge ratio of grinding media The charge ratio of grinding media refers to the percentage of grinding media in the volume of the mill.
the basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating % solids or pulp density, feed size as f80 and maximum ''chunk size'', product size as p80 and maximum .

Rod and ball mills essentially draw constant power, thus are well suited for use of synchronous motors with power factor correction capabilities as drive motors. A net of approximately 120 to 130 percent of running torque is required to cascade the charge in these mills. The pullin torque is about 130 to 140 percent with the pullout torque to ...
