Factsheet: A-Z of posho mill types and prices
A huller retails for around Sh110,000. A roller mill will usually cost Sh245,000, while a maize crusher goes for about Sh165,000. A hybrid of both roller and crusher will cost about Sh400,000. An alternative is to use just a posho mill and a huller alone, which are enough to produce quality whole meal, market-ready flour.
