When the output of the ball mill is getting lower and lower, the first thing to consider is whether there is “full grinding”, which is the main culprit affecting the output of the ball mill.
The reasons for “full grinding” are: too much feeding amount; the hardness of the grinding material becomes hard and the particle size becomes larger; the water content of the grinding material is too large; the gradation of steel balls is unreasonable; blockage.
The solution to the problem of “full grinding”: reduce the feeding amount; when the size or hardness of the grinding material changes, make corresponding adjustments in time; adjust the water content of the grinding material; reasonably configure the ratio of large, medium and small steel balls; clean up Blockage of the partition board or grate seam; increase the ventilation of the ball mill barrel.
When the temperature of the ball mill increases, the effective strain of nanomaterials formed by the ball mill decreases and the grain size increases, which significantly affects the mechanical properties of the powder made of blocks. And no matter whether the final product of ball milling is solid solution, intermetallic compound, nanocrystal, or amorphous phase, diffusion is involved, and diffusion is affected by grinding temperature, so temperature is also an important factor affecting the output of ball mill.
The national standard stipulates: Grinding aids are allowed to be added in the cement production process, but the mixing amount shall not exceed 1%. It is unreasonable to add more than this standard. In addition, most of the grinding aids are substances with strong surface activity, which are not suitable for use. All materials should be added reasonably according to the nature of the materials.
