Ball Mill

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

Load behavior and mill power

The basic form of the torque-arm model for mill power is P ( watts )= 2π 60 N ( rpm )T ( Nm) T= Force (N)× Torque - arm ( m )= Mg x cog. All the torque-arm models attempted to relate torque to mill design, load properties, and operating conditions. In this paper, a direct application of the above formula to calculate the power drawn by a ...

2.2.2 Heat from oil churning. Owing to the complexity and irregularity of the lubricant flowing inside the narrow space of the bearing, an empirical formula [14, 37, 38] is used to calculate the heat generated by the viscous churning effect (oil churning on balls, cage, and rotating inner ring).

Load behavior and mill power

Load behavior and mill power. Load orientation is conventionally described by using shoulder and toe positions and a chord connecting the shoulder and toe position with its slope equivalent to the angle of repose of mill load. This model suffers a marked discrepancy with the true load orientation at low ball filling or high speed of rotation.
