How to calculate the weight of the grinding rods in a coal grinder
Thread Content
We usually record the quantity and specifications of the rods, and estimate the consumption based on the degree of wear; approximately 2 tons are consumed per month
Generally, it is done by adding steel rods based on the particle size distribution of the coal slurry! ! !
The change in rod diameter, when measured in terms of the number of roots, is basically minimal
Actually, using “tons” to measure this grinding rod isn’t very appropriate; it’s different from ball mills； Using “roots” is more practical; alignment is also more accurate when done on a per-root basis ； So, trying to calculate the weight of the grinding rods inside the mill is a bit arbitrary – whatever number of rods are removed, that’s how many will be left; simply add as many rods as were removed ； As for the specifications, depending on the particle size – if, based on previous grinding, the particles are too coarse, then try using rods with a thickness of 5 mm, which is the thickest among those used for initial grinding; the opposite is true as well ；
