Abstract
This study was conducted to evaluate the ĞīĞcƚ of rotor speed and screen size on power consumed during milling ŽƉĞrĂtiŽn͘ The milling system was tested using three ĮƐŚ feed ingredients; bone meal, groundnut cake and maize, the moisture content of the ingredients bought from the market are 13.1%, 14.7% and 17.5% dry basis rĞƐƉĞctivĞůy͘ The milling machine was evaluated with 3 kg of each feed ingredient and was replicated three timĞƐ for each of the experimental parameters. The machine parameters varied during the experiment includes four screen size (1.5 mm, 2.0 mm, 2.5 mm and 3.0 mm) and ĮvĞ rotor speeds (1500 rpm, 1800 rpm, 2100 rpm, 2400 rpm and 2700 rpm). Regression analysis was carried out on the data collated. The analysis was used to develop model which is capable of ƉrĞĚŝctinŐ the electrical energy (kJ) consumed. There was no ƐŝŐnŝĮcĂnƚ ĞīĞcƚ of screen size on the average power consumed during milling since there is no linear rĞůĂtiŽnƐŚŝƉ between power consumed and screen size. However, there is a ƐŝŐnŝĮcĂnƚ ĞīĞcƚ of speed on average power consumed, the power consumed increases as speed decreases therefore making milling ŽƉĞrĂtiŽn at higher speed to be cost ĞīĞctivĞ since it doesn’t require much power to achieve the required output. The P-Value depicts that screen size has no ƐŝŐnŝĮcĂnƚ ĞīĞcƚ on the electrical energy consumed during the milling ŽƉĞrĂtiŽn while speed has ƐŝŐnŝĮcĂnƚ ĞīĞcƚ on the electrical energy used at 95% cŽnĮĚĞncĞ level.
