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.
Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.

Ball mills: design and operating principle. The Samara Strommashina plant has been manufacturing ball mills since the middle of the twentieth century. Hundreds of mills of most diverse modifications have been manufactured over 70 years of the plant operation.
stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method. Rod mill and AG/SAG mill products are similar and tend to be not as steep as a slope when plotted on loglog paper. ... parameters are inputted for the speci c power calculation. fi
Most of the abovementioned ball mill process parameters are continuously monitored with the help of sensors and the entire technological process is controlled by a computer. The energy consumption for operation of the whole ball mill system is about 200 kW per ton of leady oxide.
Harvey Tools reduced shank ball mills are great! We make deepdraw vacuum forming molds and these ball mills leave a nice finish. Most tool makers do not make these 4"+ let alone have them in stock! 11 of 12 people found the following review helpful:
The TM 300 Drum Mill is used for the preparation of granules and powders. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.
The ball mill is easy to maintain as all wear parts are manufactured from high grade materials and are easily accessible for replacement. The design of the vessel, shaft pin configuration, and ideal parameter control, make this ball mill the most efficient in today's market.
Effect of operating parameters in stirred ball mill grinding of coal. One of the most energyefficient devices for producing micronized coal is the stirred ball mill In the present work, various operating parameters such as stirring...
Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, ... Quantitative estimations of these parameters can be .
parameters of both distributions are equal in Eqs. 7 and 9: m c. (10) In the second part of the paper, we will investigate the hypothesis defined by Eqs. 8, 9 and 10. 3. Experimental Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40%
A study on the effect of process parameters in stirred ball mill An experimental study on the fine grinding of calcite powder (d50 = μm) using a l laboratory stirred ball mill has been carried.
Ball Mill. SBM ball mill is one of the new high efficient grinding machine,which is widely used in the in various types of stone grinding plant, ore benefication, electricity, cement and chemical new type ball mill with high comminution ratio, it can carry out dry or wet pulverizing and can meet demand for sustainable largescale production.
Since its introduction in the 1960s the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw. Along with comminution circuit design the work index parameter is widely used in tracking mill performance. Due to the age and lack of .
