You have to consider power supply, especially in the less developed areas. You need a reliable source that is within your ability to pay.
As we all know, the power of flour milling unit usually is too big to use domestic electricity, most of the machines need 3 phases electricity (industrial electricity). So you need to confirm if the 3 phases power is available in your area. Besides, you need to confirm the voltage of the maize mill before you purchase them.
We can provide flour mill machines with different motors to meet the voltage of customers and make sure all the motors can work under the power in your workshop.
Besides, If you are in a rural area where the power supply is not stable or not available, you can purchase a generator for the flour mill.
