Maize flour is majorly used in nutritional food, animal feed & baking products all over the world. The process of obtaining maize flour starts with cleaning of Maize Kernels, and the requirement for sieving starts from the beginning itself. Before the Maize kernels are transferred for grinding, it needs to be a fine sieve to remove sand and other small particles than maize kernels. Also, it needs to be passed from a coarse screen to remove impurities that are bigger than corn, for example, corncob particles.

Once it is cleaned the actual process of grinding & milling starts. During the various processing stages like cleaning, drying and milling, chances of contamination such as dust particles, ferrous particles, metal parts like screws, etc are high. Also due to moisture lumps are formed, so vibrating sieving machine is installed in the processing line to conduct safety/check screen for removing lumps, impurities, and unwanted particles & maintain the product quality.

Also, different grades of maize flour are required for different kind of products. Maize flour is classified into 4 grades: Grade 1 and Grade 2 are mostly maize skin and the small proportion of maize flour, so they are used for animal feed; while Grade 3 and Grade 4 are fine maize flour for edible. So apart from removing impurities, the vibro separator is also required for grading maize flours into a different grade.
