Ball Mill Design/Power Calculation. Ball Mill Power/Design Calculation Example #2 In Example No1 it was determined that a 1400 HP wet grinding ball mill was required to grind 100 TPH of material with a Bond Work Index of 15 ( guess what mineral type it is ) from 80% passing inch to 80% passing 100 mesh in closed circuit

2 MODELLING THE SPECIFIC GRINDING ENERGY AND BALL MILL SCALEUP Ball mill scale up (Bonds Law)Data zBond work index w i zFeed D f and product d size (both 80% cumulative passing) Result The specific grinding energy w Mill power draw P = wT, where T the mill capacity Mill dimensions (from Tables or charts)

To accelerate the math or calculation you can use the shortened formula D m <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only single sized balls and not a mixture without consideration for ball wear.

The SAG mill product is then crushed to 100% passing 3.35 mm and is subjected to the Bond ball mill work index (S d BWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability (W SDT) and the Ball Mill

laboratory ball mill. This method is based on two power calculation approaches used in ball and rod mill design processes due to its simplicity and workability. The first approach, which is specific power calculation, determines the power required to grind an ore from a given feed size to a specific product size. The second

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill

Bond ball mill work index (S d BWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability (W SDT) and the Ball Mill grindability (S d BWI) both in kWh/t, as well as the ore specific gravity.

Equation 1 is multiplied by the factor of 1.08. A multi compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the

Ball Mill Ball Mills Steel Ball Mill. Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s.

Mar 31, 2008Best Answer A ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high chromium steel.
