  • Manual processing of millet and sorghum stem residues is time-consuming.
  • Unutilized residues are often burned, contributing to soil carbon depletion, local air pollution, and unnecessary CO2 emissions.
  • Traditional feeding methods lead to sub-optimal animal diets and reduced digestion.
  • Storage and preservation of feed products face difficulties.
  • Dryland areas in Sub-Saharan Africa experience feed biomass scarcity due to low rainfall.


  • Allows for chopping or crushing of residues, ensuring they are used effectively as feed or mulch, reducing wastage and maximizing livestock nutrition.
  • Provides animals with balanced and digestible diets, leading to improved health and productivity in livestock rearing.
  • The processed residues produce higher-quality manure, contributing to improved soil health and long-term agricultural sustainability.
  • Enables efficient compaction of feed materials in bags, improving their flavor and nutritive value.
  • Particularly beneficial for regions with low rainfall, offering a crucial solution for sustaining livestock in Sub-Saharan Africa.

  1. Transport and Setup: Easily move the mobile processor between fields using a donkey cart or motorbike. Ensure the machine is properly positioned and stabilized.

  2. Loading and Processing: Collect the crop residues from the field and feed them into the machine. Ensure a steady supply to maintain consistent processing.

  3. Operational Checks: Regularly inspect engine oil levels and moving parts to prevent clogs or damage. This ensures the machine operates efficiently.

  4. Adjustment for Desired Output: Fine-tune settings based on the desired size of feed material. This may involve modifying the size, number, and positioning of hammers for optimal operation.

  5. Monitoring and Maintenance: Train operators in routine maintenance and safety practices to keep running costs low and prevent physical injuries.

  6. Ensuring Uniform Processing: Ensure that the top and bottom rollers are functioning properly, turning in opposite directions to maintain a steady flow of stover through the machine.

  7. Crushing Process: After chopping, materials enter the crushing chamber where hammers mounted on a rotating shaft revolve at high speed. Material is further ground through the beating action of the hammers.

  8. Sizing and Screening: Material is pushed forward by the motion inside the chamber and passes through holes in an adjustable screen to achieve the desired size.

  9. Collecting Processed Material: Gather the processed feed material and store it appropriately for feeding or mulching purposes.

  10. Safety Measures: Educate operators on safety protocols to prevent accidents and ensure the technology is used efficiently and effectively
