Animal feed is manufactured using a variety of ingredients to provide a balanced diet containing proteins, carbohydrates, fats, vitamins, minerals, medicines, and other essential nutrients. In mash feed manufacturing, certain ingredients such as De-oiled Rice Bran (DRB), rice polish, etc., are already available in powdered form, whereas ingredients like grains, fish meal, GNE, soya, etc., are available in solid form and need to be reduced to a granular or powdered size suitable for animal consumption. This size reduction is carried out using a Grinder or Hammer Mill.

Once all ingredients are converted into powder form, they must be mixed in precise proportions to achieve a uniform and homogeneous feed. Mixing is done using specially designed mixers. Therefore, grinding and mixing are the two core operations involved in mash feed manufacturing.

The intake hopper of the grinder and the top inlet of the mixer are generally installed at a height of approximately 5 to 8 feet from floor level, depending on machine size. To avoid manual lifting and ensure smooth material handling, screw conveyors are used to automatically lift raw materials from floor level to the required height.
