The question of the price raises the issue of whether cheap flour mill machinery cost means any good. Remember that cheap can be expensive in maintenance and in wear and tear. So cheap is not always the best. However, some grain mills may be cheaper than others depending on their countries of origin. In some countries, cheap labor is readily available making the machines cheaper than those produced in other countries. Therefore, a cheap machine does not necessarily mean that it will give substandard products, but the country of origin may influence this "cheapness".
As you consider the flour milling machinery cost, you have to consider also the running costs. For example, the rollers will eventually wear off, and they will have to be replaced. Many other parts that are susceptible to wear and tear. It is hard to say how much your mill will cost in the running costs unless you try it. It is also hard to say how much the spare parts will cost you because each part is priced differently from the others. However, if you buy a new flour mill, it can be a long time before you go to the shops looking for parts. Another determinant of the cost is the maintenance. Will your staff carry out the maintenance repairs? Will you need to hire professionals to do that? If you have to hire someone every time the machineries stall, then that will really cost a substantial amount every year.
How much electricity does the mill consume? This too is part of the running costs of the mill. Some mills have huge production capacity yet are energy efficient. Others have small capacities yet they consume a lot of electricity. From all these assessments, it is clear that no one can really say for sure what the flour mill machinery cost will be. After all, there is so much that is involved. One thing that we can be sure of is that bigger the production capacity, then the more that the mill will cost in installation costs, electricity, space and maintenance. However, the returns will be higher than those of a small flour mill. The higher the risk then the higher the returns will be. However, every mill is made for different needs and budgets so one should choose what they can afford.
