A Separate Grade 1 and Grade 2 posho mill consists of two milling units designed to process maize into different flour grades. The Grade 1 mill uses rollers to produce fine, sifted flour, ideal for urban markets and baking. It includes a cleaner, roller mill, and sifter to remove bran and impurities, yielding high-quality flour. The Grade 2 mill uses hammers or disc mills to crush whole maize into coarser, unsifted flour, retaining bran for a more nutritious product favored in rural areas. Operating both mills separately allows flexibility, better efficiency, and diversification of products to meet varied customer preferences and maximize profits.
