Problems solved by technology

[0002] Stainless steel sieve plate has high rigidity and bearing capacity, and can be used as a rigid screening and filtering device of various shapes. It is widely used in various industries for screening, filtering, dehydration, desliming and other filtering functions. The sieve plates used in grading, screening and filtration operations in quarry, chemical, food and other industries, when screening, filtering materials, and filter bodies, the movement of granular materials will cause serious wear and corrosion to the sieve plate, often causing the surface of the sieve plate to be damaged. The edge of the sieve hole is severely worn, which affects the accuracy of material screening, which significantly reduces the service life of the sieve plate, and the replacement of the sieve plate will prolong the production cycle, increase production costs, and reduce production efficiency.
