In Kenya, posho mills are mainly classified based on power source, milling grade, and capacity, making it easier for buyers to choose a machine that fits their location, budget, and business needs. The most common types are electric posho mills, diesel posho mills, and combined electric & diesel posho mills.

Electric posho mills are widely used in towns and trading centres where electricity is reliable. They are affordable to run, easy to maintain, and ideal for small to medium milling businesses. Most electric posho mills come in single-phase (for homes and small shops) or three-phase (for higher commercial output) options. They produce consistent flour quality with minimal noise and no fuel costs.

Diesel posho mills are popular in rural and off-grid areas where electricity is unreliable or unavailable. They are powerful, handle hard or dry maize well, and can run for long hours if properly cooled. However, they have higher operating costs due to fuel consumption and require regular maintenance of the engine and cooling system.

Combined electric and diesel posho mills offer the best of both worlds. They allow millers to switch between electricity and diesel depending on availability, reducing downtime and ensuring business continuity. These machines are ideal for serious biashara owners who want reliability, flexibility, and higher daily output.

Posho Mill Grades Explained (Grade 1 vs Grade 2)

Posho mills in Kenya are commonly classified into Grade 1 and Grade 2 based on the type of flour produced and the milling process used. Grade 1 posho mills are designed to remove maize husks and bran before grinding, producing fine, white, sifted maize flour. This flour is popular in urban areas and commercial markets because it cooks smoothly and has a soft texture.

Grade 2 posho mills, on the other hand, grind the whole maize kernel without removing the bran. The result is whole-maize flour, which is more nutritious, heavier, and preferred in many rural households. Grade 2 machines are simpler, require less setup, and are generally cheaper to operate and maintain.

How to Choose the Best Posho Mill in Kenya

Choosing the best posho mill in Kenya requires assessing your power availability, daily workload, and long-term goals. First, determine whether you have reliable electricity; if not, consider a diesel or combined electric/diesel model for flexibility.

Next, match the horsepower to your expected daily maize volume — 7.5HP works for small to medium usage, while 10HP+ suits commercial workloads. Consider Grade 1 vs Grade 2 based on the flour quality you want. Also check cooling, ventilation, and belt setup to prevent overheating. Finally, factor in after-sales support, delivery, and warranty before buying.
Posho mills are reliable machines, but like all equipment, they can develop issues if not properly set up or operated. One common problem is overheating, usually caused by continuous grinding without breaks, poor ventilation, tight belts, or incorrect power supply.
The solution is to allow cooling intervals, improve airflow, and adjust belt tension. Another issue is poor flour quality, often resulting from worn or tightly set grinding plates; regular inspection and correct adjustment solve this. Diesel engines overheating is commonly due to low water levels, dirty radiators, or lack of coolant—routine cleaning and proper cooling fluids prevent this. Lastly, frequent motor tripping is linked to voltage drops or overloading, which can be fixed by using proper cables and matching the mill’s capacity to the workload.
What Could Be Causing the Overheating?

1️⃣ Electric Motor Overheating (Most Common Cause)
The electric side stopping after some hours usually happens because:
❌ Wrong electrical supply
Single-phase power trying to drive a heavy load continuously
Long extension cables (voltage drop)
❌ Poor ventilation
Motor placed in a closed room with no airflow
❌ Incorrect pulley alignment or tight belts
Causes friction → heat → auto-cutoff
❌ Continuous grinding without breaks
These machines are not industrial continuous-run mills
✅ Fix
Ensure correct voltage
Use short, thick power cables
Give the motor 15–20 min rest after 1–2 hours
Check belt tension (not too tight)
2️⃣ Diesel Engine Water Overheating
If the diesel water is heating up:
🔥 Radiator cooling problem
Dirty radiator fins
Low water level
🔥 Running at high RPM continuously
🔥 Poor airflow around engine
🔥 Using plain water instead of coolant
⚠️ This is NOT because of 90 kg per day — that’s light work.
✅ Fix
Clean radiator fins
Top up water / add coolant
Ensure fan is working
Avoid continuous long runs (breaks are key)
3️⃣ Grinding Setup Issue (Very Important)
Sometimes the problem is not the engine at all:
⚙️ Grinding plates too tight
Causes extreme resistance
🌽 Grinding very hard or dry maize
🔧 Poor alignment between mill & engine
✅ Fix
Slightly loosen grinding plates
Ensure proper alignment
Avoid feeding maize too fast
How much does a posho mill cost in Kenya?
Posho mill prices in Kenya range from KSh 64,000 for small electric units to over KSh 370,000 for commercial roller mills, depending on horsepower, grade, and power source.
Which is better: electric or diesel posho mill?
Electric posho mills are cheaper to run and ideal where power is reliable. Diesel posho mills are best for rural or off-grid areas. Combined electric and diesel models offer flexibility and uninterrupted operation.
Is a 7.5HP posho mill enough for biashara?
Yes. A well-set 7.5HP posho mill can grind 300–500 kg per day with proper cooling breaks and correct setup, making it suitable for small to medium businesses.

What is the difference between Grade 1 and Grade 2 posho mills?
Grade 1 produces fine sifted white flour, while Grade 2 grinds whole maize flour with bran. The choice depends on customer preference and market location.
Why does a posho mill overheat?
Overheating is usually caused by continuous running, poor ventilation, tight belts, wrong power supply, or tightly set grinding plates—not overload.
Basic inspection should be done weekly, while full servicing is recommended every 3–6 months to ensure efficiency and long machine life.
