Frequently Asked Questions
Diagonal hole plates are optimized for high efficiency and self-cleaning with superior strength, while parallel wave hole plates offer a higher opening rate for maximized throughput and enhanced screening effects.
For grading sizes between 0.35-3mm, we recommend alloy steel for high wear resistance. For sizes between 0.35-1mm in non-magnetic requirements, non-magnetic stainless steel is the ideal choice.
Our screens feature a hardness of 80-95 Shore A, which provides the necessary balance between elasticity (to prevent brittle fracture) and rigidity (to maintain aperture shape under load).
Yes, polyurethane is inherently resistant to many chemicals and corrosive agents, making it an excellent choice for mining beneficiation and coal washing where harsh environments are common.
Depending on the abrasiveness of the material and operational intensity, the normal service life typically ranges from 6 to 12 months.
Our advanced manufacturing process allows for a minimum aperture of 0.015mm, enabling extremely fine separation of granular materials.
