Traditional absorption costing methods, which are based on proportional allocation of overhead costs according to direct costs consumed by products, are unable to calculate costs relating to capacity changes. The calculation for the rate of overhead is normally based on past data, with no consideration for possible capacity changes (Drury, 2001).

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

To obtain maximum mill capacity several variables in groups are considered. 1. Group I
Production Capacity of One Product: Here, the amount of time required to produce one unit is divided by the machine-hour capacity. Production Capacity of Multiple Products: Most factories produce more than one product. In this case, each product is calculated as it would be for a single product, then added to the output of the other product.

process must be illustrated clearly in a yearly, monthly, daily, and hourly rate. The capacity not only determines the mill equipment size, but also dictates how to operate the mill, whether continuous or batch operation is required, and whether the process can be performed in-house or if a tolling service is a better option.

Answer: Good question. In the production capacity calculation formula, we are using product SAM to calculate the daily production capacity. Therefore, if you are adding finishing operation SAM, manual work (like marking, ironing) SAM, into the total garment SAM, those workstations will be part of the calculating factory capacity working hours.

In the case of multiple processing options, cut-off grade is used to determine which process or destination the ore will be sent to, by using the following equation: Where U1 is the utility of sending ore to process 1, and U2 is the utility of sending ore to process 2. Utility is defined as the value (economic or otherwise) of selecting a process.
