（1） Basic principles of strike and impact cleaning

According to the different strength of grains and impurities, in the working screen with certain technical characteristics, the high-speed rotating striking plate is used to strike grains, so as to make repeated collision and friction between grains and striking plate, grains and screen cylinder, grains and grains, so as to achieve the purpose of separating grain surface impurities from grains.

Impact is the impact of high-speed rotating rotor on grain, the impact between grain and impact ring, and repeated collision and friction between grain and grain, so as to separate grain surface impurities from grain or break grain.

(2） Application of strike and impact cleaning

Strike and impact are mainly used for wheat surface cleaning and corn degerming. Generally, two threshing processes are used in wheat cleaning. If wet cleaning is used, two threshing processes can also be used. If two courses of threshing are adopted, it is generally light threshing before water regulation and heavy threshing after water regulation.

This is because the wheat is hard and brittle before watering, so it is easy to produce too much broken wheat and break wheat germ in heavy beating, which will affect the effect of subsequent cleaning equipment and water regulation. The surface toughness of wheat increased after water, and heavy beating was beneficial to surface cleaning.

After each threshing (impact), screening and air separation should be carried out to improve the surface cleaning efficiency. The equipment used for grain surface cleaning mainly includes: Wheat beater, wheat cleaning machine.

Strike and impact can also be used in the milling part, playing the role of auxiliary grinding, auxiliary screening, loosening and insecticidal. The main equipment includes bran beating machine, plate beating round screen, loosening machine, insecticidal machine, etc.
