### The Ball Mill Load Measuring algorithm though Grinding

ball mill power is affected by steel ball load, the sensitivity of detection signal is low [5]. Seriously affected by the revolving speed of ball mill, elevator abrasion and the granularity distribution inside ball mill, the air pressure method is hardly popularized [6]. Get price

### Measuring ball mill ventilation

It is preferable to measure the air velocity entering the mill inlet using a simple hand-held anemometer. This will indicate the actual air flowing into the mill and will discount the impact of false air. Some allowance does need to be made for any additional air that may enter either with the raw materials or back from the re-circulating load Get price

### Ballnose Cut Depth Musings for Feeds and Speeds in G

Simply put, the cutting edges get less access to coolant and air for cooling and it is harder for them to drag the chips up and out of the way. Hence we penalize surface speedand chip load. Here again, the definition makes sense given that we're making chips all along the full distance (radius of the ball). Get price
