Abstract
The main experiments were carried out in a local factory in El-Obour city, El-kaluobia Governorate to study the effect of some operating parameters on the performance of two types of mixing units. The main objectives of this research are to: •Evaluating the performance of two types of mixing and processing feed additives and concentrated units • Optimizing some operating parameters affecting the performance of the used mixers (mixing Time, carrier type, and batch size). • Measuring the Energy Requirements for operating the used mixers • Comparing the used mixers from the economic point of view The performance of the mixing units was measured under the following parameters: - Batch size of 600, 800, 1000 and 1200 kg for BUHLER (big mixer). - Batch size of 100, 150,200, and 250 kg for RIBBON (small mixer) - Mixing times of 5, 10, 15 and 20 min for BUHLER (big mixer). - Mixing times of 30, 40, 50 and 60 min RIBBON (small mixer) - Carrier materials: For BUHLER (big mixer): Corn gluten and calcium carbonate - Corn gluten only - Calcium carbonate only.
