- ball mill size with motor power

2015-10-19 For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

More2015-6-19 A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power. The ball mill motor power requirement calculated above as 1400 HP

MoreThe productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is

MoreVery large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

MoreThe motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n

Replace or repair shafts and housings showing obvious signs of wear or damage. A shaft placed in a vise for mounting should be protected from vise jaws with a sheet of soft metal. 3.

More2017-6-15 The ball and tube mills are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD4772,

More19-10-2015 Ball Mill Motor Power Draw Sizing and Design Formula. The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

MorePlanetary Ball Mills are used wherever the highest degree of fineness is required.In addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and ...

More2021-2-16 Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, round-the-clock reliability and the opportunity to mine in remote areas. This makes low ore grades economical to grind. ABB has delivered some of the world's largest GMDs: • 22 MW GMD for 28’ ball mill
