Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For 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 8-hour shift, allowing to calculate corresponding to circulating load ...
Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element
The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm 'a' λ =0.5 for hot rolling and 0.45 for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = 2P.a Consider two high roll mill as shown in the figure.
