Key Features and Design
Power Sources: Locally assembled units are commonly driven by a 7.5 HP petrol engine, a 3HP or 7.5HP single-phase electric motor, or a diesel engine (e.g., 6HP–18HP).
Construction: Fabricated using locally sourced, heavy-duty materials, often featuring a reinforced steel rotor, perforated concave, and a sturdy frame.
Mechanism: Uses a rotating cylinder with spike teeth (or axial flow design) to impact the cobs, stripping the kernels through collision and friction.
Portability: Many models come with wheels and a compact structure for easy transportation between farms or storage areas.
Cleaning System: Equipped with built-in blowers and fans that clean the maize by separating chaff, husks, and dust from the grain, resulting in clean, ready-to-mill kernels.
