Grain cleaning and milling machinery is a type of equipment used in the agricultural industry for cleaning, sorting, and processing grains such as wheat, corn, and rice. This machinery is designed to remove impurities such as dust, dirt, stones, and other foreign objects from the grains, as well as to separate the grains into different sizes and grades. The cleaned and sorted grains are then processed using milling machinery, which grinds the grains into flour or other forms of grain products such as animal feed or cereal. Grain cleaning and milling machinery can range from small, manual machines suitable for use on a small farm to large, automated systems used in commercial grain processing plants. The use of this machinery can greatly improve the quality and efficiency of grain processing, resulting in higher yields and better quality products.
