Step 2. Ball mill drum dimensions. Specify the length and capacity of the drum. If not available, specify the length and diameter of the drum. Step 3 (the final). Grinding bodies. Specify the weight of grinding bodies. You can simply specify a fill ratio for the drum if you do not know the exact weight of grinding bodies. Done!
2.2 Working roll force calculation. According to the structural characteristics of the four rolls, it is easy to know that the four working rolls can be arranged in two different ways: Rollers are arranged in a symmetrical arrangement and asymmetrical manner. Therefore, it is necessary to do the force analysis of the four-roll machine separately.
How to Calculate Product Yield. The formula for the product yield is the sum of the good units and the reworked units available for sale. The formula looks like this: Y = (I) (G) + (I) (1-G) (R) Where Y = Yield, I = Planned production units. G = Percentage of good units. R = Percentage of reworked units available for sale.

weight of 14.8 grams is recorded. The No. 8 (2.36 mm) sieve is removed from the nest of sieves, the material is emptied into the pan with the No. 4 (4.75 mm) material and the cumulative weight is recorded on the worksheet beside the No.8 (2.36 mm) sieve, example 47.6 grams. Repeat the procedure until all of the sieves are weighed

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

Let me help you with a quick back of the envelope calculation. If you are using a 270 Liter Tangential Internal Mixer, you are engaging at least two units of 26″x84″ two-roll mills in the downstream section. Each 26″x84″ two-roll mill, requires around 180 kW (minimum) motor power – totaling to 360 kW (=180 x 2) only for the mills.

If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.
