According to the proposed method the calculation of power consumption was performed for the tubular ball mill Ø4x135 m. They also recorded the consumed power values concerning a similar mill at the Karachay-Cherkessia

Ball Mill Design/Power Calculation

Example Calculation. A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power.. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution.

Ball mill media optimization - Metcom Tech

mill power multiplied by the CSE. Therefore: Circuit production rate of new fine material (t/h) = Total mill power (kW) x CSE (%) x Mill grinding rate of coarse material (t/kWh) (2) Production rate mill power and CSE can be measured during a plant circuit survey. The mill grinding rate of coarse material is then calculated.

Ball Mill Parameter Selection & Calculation - Power Critical ...

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.

GROSS POWER CALCULATOR - SMC Testing

base are up to 40ft in diameter and ball mills are up to 26ft in diameter. The measured gross power draws from these mills are plotted against the model predictions in Figure 1. As indicated by this data base the accuracy of the model (1 standard deviation) is 4.6%. How to Use the Model . Inputs to the model are made in three windows viz: Mill ...

CALCULATION OF THE POWER DRAW OF DRY MULTI–COMPARTMENT BALL MILLS

of the Bond ball mill grindability test. For all model based methods a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

Ball mill media optimization - Metcom Tech

mill test the calculation method of the mill energy specific cumulative grinding rates is shown by the following example. Using plant data the value of E is the specific energy input to the solid material as it passes through the plant mill (the mill power draw divided by the mill solids throughput rate) and assumes plug
