The electronic Ears senses the noise of the mill. The Ear consist of a very sensitive microphone installed at the mill inlet, at the grinding ball impact point, and as close as possible to the mill shell. The foam of the Electronic Ear must nearly touch the mill shell between two rows of bolts.
efficiency, sound level due to the impact of clinkers rejects rate i.e. the rate at which the rejects enter the ball mill and finally fineness. C. Irregularly sampled data The data was obtained using FLSmidths ECS Cemulator . In this simulation software, a cement ball mill plant is replicated. A PRBS sequence of
When grinding cement, the ball mill has a yield of 3001000gt, and the grinding system of the roller press has a yield of 0.5gt, so it can meet the requirements of white cement. Low noise . The ball mill noise is above 110 dB, while the roller press is about 80 dB.
Feb 01, 2016 The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.
2.When cement ball mill is running,grinding media loaded inside ball mill cylinder under the effect of centrifugal force and friction force rolls alongside the cylinder wall with crushed orewhen both of them are lifted to a certain height,due to gravity effect they fall and travels along the cylinder wall under the continuous comminution,crushing and grinding of grinding media,finally the ...
