different grinding media of ball mills, rod mills and SAG mills. Crushing ratio Comparison. The biggest feature of SAG mills is the large crushing ratio, which can crush and grind the materials to 0.074mm at one time, accounting for more than 20% to 40% of the total product.
Therefore, in the running ball mill, coarse ore particles will be preferentially crushed, that is, the big ball mainly relies on impact and crushing to crush the coarse ore particles; and the pellets mainly grind and crack the fine particles by fine grinding, Form a big ball hit the big grain, small ball grinding grain state.
One-half inch is quite aesthetically appealing. This is 1/2 inch clear crush gravel, it's used commonly for either pathways and/ or driveways. it's a nice size and I find it quite aesthetically appealing once its been washed and the dust is off. it looks quite good.
