With the technological innovation the ball mill is also progressing

It is reported that the roll mill product size is relatively uniform, should be controlled within a reasonable range, the general 0.08mm square hole mesh sieve control in about 12% to meet the rotary kiln raw material, pulverized coal fineness requirements, not only reduces the fine Production, waste of energy, and increase the cycle load within the mill, resulting in poor pressure control. The speed of the MPS3150 separator is 30 to 33 r/min, and the MPS2450 is 30 to 35 r/min. Under the condition that the equipment has been set, the comminution effect depends on the grindability of the material and the tension applied and the amount of material that withstands these squeezing forces.

The adjustment range of the tensioning force is limited. In the case where the material is difficult to grind, the thickness of the material layer should be appropriately thinned in order to increase the proportion of qualified particles in the extruded material. On the contrary, the ball mill manufacturers believe that if the material is easy to grind, it can produce a large number of qualified particles in a thick material layer, so it should be appropriate to thicken the material layer, and accordingly increase the output, otherwise it will produce energy waste. The MPS3150 roll mill has a bed thickness of 80 to 120 mm, while the MPS2450 is 60 to 80 mm.

The roller mill is very smooth during normal operation and the noise does not exceed 90dB, but if the adjustment is not good, it will cause vibration. Excessive amplitude will stop automatically. Therefore, the main problem encountered during the debugging phase is vibration. The main causes of the vibration of the roller mill are: there is vibration caused by the metal entering the disc. In order to prevent the metal from entering, an iron remover and a metal detector may be installed; a pad is not formed on the disc, and the roller and the pad of the disc are in direct contact to cause vibration.
