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 mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel.

Ball Mill Design Parameters Size rated as diameter x length.. Feed System. Top of feed hopper at least 1.5 meter above the center line of the mill. Feeder. Spout feeders preferred when using a closed-circuit with classifying cyclones. Cyclones are typically installed. Discharge . Exit about 5 .

retSCH Planetary Ball Mills are used for the pulverization of soft fibrous hard and brittle ma-terials. They achieve a very high final fineness down to the submicron range. The feed size depends on the mill and can be as large as 10 mm. If the sample feed size is larger than this then the sample must first undergo preliminary size reduction.

A ball mill grinds ores to an end product size of thirty-five mesh or finer. The feeding material to a ball mill is treated by Single or multistage crushing and screening Crushing screening andor rod milling Primary crushing and autogenoussemi-autogenous grinding. Normal feed sizes

Jun 01 2020 Therefore in ball milling processing the operator of ball mill should monitor the feeding size closely. If the particle size is over the designed limit feeding should be stopped or reduced and take relative measures to guarantee the feeding particle sizes. 2Unsatisfied steel ball filling amount.

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 .
