2019-10-08· The ball mill noise is related to the diameter of the ball mill, the speed of the ball, and the nature and blockiness of the material. The ball mill noise is basically steady-state noise, wide frequency range, the larger the diameter, the stronger the low frequency noise. Methods of reducing ball mill noise …

Ball mill noise is mainly mechanical noise caused by the collision between the metal ball in the drum and the cylinder wall liner and the processed material. The intensity of the ball mill noise is related to the diameter and speed of the ball mill, as well as the nature and blockiness of the material. Ball mill noise is basically steady-state noise…

This method usually gains the noise reduction of 25-45db (A), but it does not effectively isolate the ball mill transmitting to the outside. There are two types of acoustic enclosure: stationary type and movable type. Some ball mill manufacturers will equip with the acoustic enclosure at random for users, but because the ball mill is too large, the measure makes the ball mill poorly ventilated ...

MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a 0.4% grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills. The concentrate is transported to a ...

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. The ...
