In Kenya, the price of a first-class corn mill varies depending on many factors, and the approximate price range is between $2,000 and $39,000. Here are some common price ranges and corresponding equipment features:

1. Lower price range (about $2,000 - $6,000):
- This type of corn mill usually has a relatively small production capacity, and the processing volume may be within a few tons per hour. For example, some small machines suitable for small workshops or families have relatively simple functions and low automation. The operation may require more manual participation, but it can meet basic corn milling needs.

2. Medium price range (about $6,000 - $20,000):
- First-class corn mills in this price range have good performance and production capacity. The production efficiency is high, the processing volume may be between a few tons and more than ten tons per hour, and the stability and durability of the equipment are also good. They may be equipped with a more advanced control system, which is relatively easy to operate and can ensure the processing quality and production continuity of corn flour.

3. Higher price range (over $20,000, even up to $39,000)
- High-priced corn mills are generally large, industrial-grade equipment with high production capacity, and the processing capacity may be more than tens of tons per hour. These machines are manufactured with advanced technology and high-quality materials, with a high degree of automation, precise control functions, and powerful grinding and screening capabilities. They can produce high-quality corn flour, and also have good performance in energy consumption and maintenance costs. They are suitable for large corn processing companies or factories.

It should be noted that the specific price will also be affected by factors such as brand, equipment configuration, and after-sales service. When purchasing a corn mill, it is recommended to choose the appropriate equipment according to your own production needs and budget.
