You need a mill (plate or hammer), a power source (a diesel engine of about 10 to 16 HP, or an electric motor where there is three-phase power), a belt drive and base frame, a dry building with a firm floor, and a stock of spares such as plates, sieves and belts. Check the business permits needed with your county government before you start.
A posho mill can be a steady business in any town or trading centre. Here is what to plan before you buy.
1. Choose your power source
- Electric motor – the cheapest to run, but it needs reliable three-phase power. Ask KPLC about connection before you decide.
- Diesel engine – works anywhere and is the usual choice in rural areas. Engines of about 10 to 16 HP are common for village mills.
2. Choose the type of mill
- Plate mill – grinds between two plates. Common for maize flour in small mills and simple to maintain.
- Hammer mill – uses fast hammers and a sieve. Handles larger volumes and animal feed well.
Ask for the rated output in kilograms per hour so you can match the mill to the business you expect.
3. Prepare the building
- A firm, level concrete base for the mill and engine, so vibration does not loosen them
- Good ventilation, especially for a diesel engine, and a safe exhaust outlet
- A dry store for grain and flour
- Space for customers to queue safely away from moving belts
4. Keep spares in stock
A mill that stops loses customers. Keep at least:
- A set of grinding plates or hammers
- Sieves in the sizes you use
- V-belts
- Engine filters and oil
You can find these on our spare parts page.
5. Permits and safety
Check with your county government which business permit you need, and follow public health rules for food handling. Fit a guard over belts and pulleys, and never let children near the machine while it is running.
6. Installation
A posho mill must be aligned correctly or belts and bearings wear out fast. We deliver complete sets to all 47 counties and can install and test them on site.
Common questions
How much power does a posho mill need?
Village posho mills commonly use a diesel engine of about 10 to 16 HP, or an electric motor of similar size where three-phase power is available. The exact size depends on the mill model and output.
Can a posho mill run on single-phase electricity?
Most commercial posho mill motors need three-phase power. Where only single-phase power is available, a diesel engine is usually the practical choice.
