electromechanical dynamic behaviour and start-up

This paper presents a dynamic simulator of the electromechanical coupling start-up of a ball mill. The electromechanical coupling model based on the dynamic model of the ball mill, the characteristic equation of the clutch, and the dynamic model of the induction motor is established. Comparison between the simulation results of angular speed, load torque and current obtained from the model

maintaining wastewater treatment plant operating

Under the current economic climate, many mills are experiencing more frequent and/or longer production outages. But the wastewater treatment system is a living “organism,” requiring a constant food source to remain viable. During extended down times, the mill sends little or no “food” to the microbiological population (bugs) resulting in a gradual depletion of the […]

ball mill- an overview | sciencedirect topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones
