To produce Grade 1 flour:
Maize is first crushed (Grade 2 stage)
Then it is sifted/refined (Grade 1 stage)
therefore Grade 1 needs Grade 2
A Grade 1 posho mill is a milling system that produces fine, sifted maize flour by removing bran and impurities after grinding. Unlike basic mills, it does not just crush maize — it processes and refines it into smooth, white flour that most urban customers prefer.
