700=0.65*700 + 0.35*700=385+315. The 385 tons underflow will be recycled. 315 tons is the overflow will be taken for the further operations. Therefore 315 tons per hour is the fresh feed. The circulating load ratio is equal to 385 upon 315, so that is equal to 1.22. Circulation Load Ratio Calculator.

Milling Step-over Distance Calculator. In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

The in-mill load volume and slurry solids concentration have significant influence on the ball mill product size and energy expenditure. Hence, better energy efficiency and quality grind can only be achieved with correct tuning of these influential operational factors to the desired optimum point.

A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge; causing, the Total Charge Filling …

The ball loading capacity of the mill can be calculated according to the formula (1-14). Gra — Quantity of Grinding Medium, T. Rho s — loose density of grinding medium, t/m3.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

Re: Ball Mill Load & feed. Dear GKS, You are correct in stating that main drive kw only increase when less grinding media charge and small size of grinding media w.r.t. feed size and feed rate. However, it was to be stated in my reply that Kwh/t of material increases in chocked condition of the mill as there is no output from the mill. Warm regards

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and …

Here's how you would calculate the load weight of a block of aluminum that is 6 feet long, 3 feet wide, and 4 feet tall: Volume = Length x Width x Height. Volume = 6 feet x 3 feet x 4 feet. Volume = 72 cubic feet. Aluminum weighs 165 pounds per cubic foot (based on the numbers from the table above).
