Chaffcutter Machine 900r/min 1000kg/h

Power Requirement

To achieve a sustained $1000\text{ kg/h}$ capacity, the machine typically requires:

• Motor: ²$2\text{ HP}$ to ³$3\text{ HP}$ electric motor.⁴

   

• Engine: Alternatively, a $5\text{ HP}$ to $7.5\text{ HP}$ petrol or diesel engine may be used for mobile or off-grid operation.

• Note: The motor’s actual speed (RPM) is often higher (e.g., $1440\text{ RPM}$), and the pulley system is used to reduce that speed down to the required $900\text{ r/min}$ at the cutting rotor.

2. Design and Construction

• Material: Usually made from Mild Steel (MS) for the body and robust, high-carbon or manganese steel for the cutting blades.⁵

   

• Blades: Typically features 2 or 3 heavy-duty, sharp steel blades for precision and longevity.⁶

   

• Rollers: Includes feed rollers to automatically pull the fodder material into the cutting chamber, enhancing safety and efficiency.

3. Application and Benefit

• Function: Chops coarse fodder (hay, straw, stalks) into smaller, uniform pieces (chaff).⁷

   

• Benefit: This increases the digestibility and nutritional absorption of the feed for the livestock, leading to less wastage and healthier animals.⁸
