Description: The screen frame (mesh frame) of the corn screening and impurity removal vibrating screen is a core load-bearing accessory of linear grain cleaning screens and corn primary cleaning vibrating screens. It is used to tension and support the screen mesh and is installed inside the screen box of the equipment. The screen frame continuously withstands the impact of corn materials and high-frequency reciprocating vibration, keeping the screen mesh flat and taut, stably achieving corn impurity removal and grading and separating straw, mud lumps, broken corn, shriveled kernels and dust. It is widely used in the cleaning sections of corn purchasing stations, feed mills, corn starch plants and corn deep processing EPC production lines.
