Grinding experiments were performed on a laboratory-scale cement ball mill, with a diameter of 500 mm and a length of 500 mm, as shown in Fig. 3. Ore samples of rock asphalt was used in the experiment. The samples were crushed (60.0% particles below 3 mm) and well mixed before grinding.
When grinding cement, the abrasion of the ball mill is 300-1000 g/t, while that of the roller press is 0.5g/t, so it can meet the requirements of grinding white cement. Low Noise The noise of the ball mill is more than 110d, while the cement roller press is about 80dB. Environmental Friendly. Read On
The charge of grinding media for two-compartment ball mill can be calculated for dry grinding of cement raw mix. The medium-hard raw material for the mill feed has a particle size range of 0.5 to 25 mm. The mill dimensions are: -. Inner diameter of mill = 4.2 m. Length of drum = 15.25–1.0 = 14.25 m.
Maximal Noise Exposure: How to Use This Calculator. To use this noise pollution calculator, enter the noise level in deceibels (dB) and it will automatically calculate the maximum amount of time for safe exposure. You should never expose yourself more than this displayed time to protect yourself from hearing loss.
