OPERATING BUDGET
This will be considered per hour of operation for a 400kg/hr mill using a diesel engine
Note that the 400kg �gure is for a constant �ow of maize. In practice, a �gure of 300 kg/hr
of product is a reasonable output and the following calculations are based on 300kg/hr:
The costs are calculated in $US so that costs in Kwacha can be derived by converting at the
current exchange rate.
COST OF PROCESSING 300KG OF MAIZE (1 HOUR OF OPERATING)
USING A DIESEL POWERED ENGINE
$US
Capital cost depreciated over 10,000 hrs ($5,563/10,000) 0.5563
Cost of building dep.over 10,000 hrs ($1,600/10,000) 0.16
Diesel (2.6litres @ 0.9$/l) 2.34
Engine oil (.015litres@$3/l) 0.045
Filters – diesel and oil ($29/250hrs) 0.1303
- air cleaner elements ($55/500hrs) 0.11
- hydraulic oil �lters ($102/1,000hrs) 0.102
Belts ($11/2000hrs) 0.0055
Labour ( 2 workers @ $1.5 each/7hrs working day) 0.4286
Screens ($15/1,000hrs) 0.015
Sieving screen ($50/2,000hrs) 0.025
Total cost for 300kg = $3.9177 = $0.01306/kg = $0.235/Tin of 18kg
At a Kwacha/dollar exchange rate of 3,500 this is K822=50
KEEPING RECORDS and CONTROL!
This is WITHOUT any PROFIT!!!
