The efficiency of the grinding circuit is. 100(Wi/Wioc) = Grinding efficiency in percent.....(3A) The multipliers for the efficiency factors can be determined from the following: EF1 Dry grinding - for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding.

The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′).

Abstract: - Efficiency of industrial production lines is crucial as it results in an improved production and utilization of available resources. Factors contributing to production line efficiency are manpower utilization and machine efficiency. Measuring the machine efficiency and man power utilization should be on-line, accurate and truthful.

Machine Hours Rate: Formula, Calculation, Problems and Solutions! The machine hour rate is similar to the labour hour rate method and is used where the work is performed primarily on machines. If factory overhead is Rs 3, 00,000 and total machine hours are 1,500, the machine hour rate is Rs 200 per machine hour (Rs 3, 00,000 ÷ 1500 hours).

3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
