SCREEN MAT OF SCREEN DEVICE

摘要

PURPOSE: A screen mat for a grain separator is provided to reduce a waste of space of a mat by minimizing the space between holes, thereby maximizing material separating process efficiency per unit area. CONSTITUTION: A screen mat(10) for a grain separator is formed with multiple holes(17) on the surface in order to separate grains of materials. The holes are formed in the direction of the progress of the materials by being alternately broken away from the same straight line. The hole has a quadrangle structure. The hole has a circular structure. The hole has a hexagonal structure. The hole is composed of a right hexagonal structure. Each hole is arranged as a honeycomb structure.
