Ball mill ball mills wet & dry grinding dove
Influencing factors of classifier output. powder concentration turbine classifier rotate speed air volume and air pressure classifying efficiency particle size distribution product fineness. the relationship between ball mill and classifier. ball mill output raw material feed amount coarse material return after classifying classifier output classifier throughput – classified coarse materialThe working principle is simple, impact and attrition size reduction take place as the ball drops from near the top of the rotating hollow cylindrical shell of the ball mill. the output materials will be feed to the processing and recovery machines.Cement ball mill. 4 factors that affect the capacity of cement ball mill. 1.feeding size of cement. the smaller the particle size of cement material, the higher the output and efficiency of the cement ball mill, contrarily, the cement ball mill has lower yield and higher running cost. 2.moisture of cement. cement ball mill grinds cement by dry Crushed ore is fed to the ball mill through the inlet a scoop small screw conveyor ensures the feed is constant. for both wet and dry ball mills, the ball mill is charged to approximately 33 with balls range 30-45. pulp crushed ore and water fills another 15 of the drum’s volume so that the total volume of the drum is 50 charged.Ball size distribution in practice, at mill startup, instead of charging a single size of ball, usually a range of ball sizes is initially added.7.6 a ball mill is to produce a grind of 34 micron pso product from a feed size of 200 microns at a rate of 1.5 th.Ball milling output increased with increase in grinding time, ball mass to ore sample mass ratio and very slowly with increase in mill speed. the response decreased with increase in ball size. this work established a model for selecting the parameters required for a desired size reduction ratio. the workThe client provides the desired production feed rate and particle size and we extrapolate or directly correlate the mill size based on the test data. the mills scale up proportional to gas flow. and, since we have an extensive custom grinding and test facility with over 12000 scfm of oil-free air available for testing, we often are able to test The optimisation of a ball mill circuit and is supported with typical case study done by holtec in a 1.5 mio ta to improve mill output and reduction in power consumptions in the ball mill system. diagnostic study • high variations in the mill feed size on 25 mm sieve observed, which shall result in variation in the mill Wet grid ball mill capacity 0.5-500tph feed size ≤25 mm. grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. the size of ore shall not exceed 65mm and the best feed size is under 6mm.
