“EXPERIENCE WITH SYNCHRONOUS AND - Cimentec

The torque speed characteristic curve for a recent ball mill is shown in Figure 2. Mill suppliers define the starting torque at an angular displacement of the charge. The cascading point of this mill is at angle of 60°. This implies that a motor connected through a 60:1 reduction be capable of transferring 120% of its rated full load torque when it

Grinding Mill Power - Mineral Processing Metallurgy

Also, for a given value of mill filling (J) the load of rods in the mill will exceed that of balls in the ratio of the volume of rods to the volume of balls, that is, 1 – 1.01/1 – 0.4 = 1.5. Thus, the power to drive a rod mill, without a powder charge, will be given approximately by. PR = 1.5PB ..(3.24)

ETAP Motor Starting Study for 600kW Ball Mill - Electric ...

The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve. The initial torque to start rotation will most likely be over 100% or

Ball Mills - an overview ScienceDirect Topics

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on small and large scales. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction, and kinetic energy between two or more elements vary greatly within the ball charge. Frictional wear or rubbing forces act on the particles as well as collision

Frequency domain characterization of torque in

01/01/2018  For a specific load and operating conditions, the torque appearing in a tumbling ball mill is a highly variable magnitude in the time domain. This fact is due to the operating principle of ball mills, which is based in the elevation process of balls and material from the toe region to the shoulder region of the drum. Following the elevation process, the consequent fall of the particles inside the mill generates
