WhatsApp: +86 18838072829For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour.
WhatsApp: +86 18838072829For example, if you are making a ″ depth of cut with a 1/4″ ball nose end mill, the feed rate would be around 10 IPM. Adjust the feed rate based on the rigidity of the setup. A more rigid setup can handle higher feed rates, while a less rigid setup may require lower feed rates to avoid chatter.
WhatsApp: +86 18838072829In the work cited the calculation of such wear has, to a first approximation, been carried out and it is suggested that the relationship between rate of wear and relative hardness of ball and particle has the form shown in Fig., whilst the relationship between rate of wear and quantity of powder in the mill has the form of Fig.
WhatsApp: +86 18838072829Feed Rate = Spindle Speed * Chip Load * Number of flutes You can manipulate this equation to calculate for unknown variables, if necessary. For example: Chip Load = Feed Rate / (Spindle Speed * Number of Flutes) You should also consider the hardness of your material and the intricacy of your design, as mentioned above.
