Frequently Asked Questions
Polyurethane screens offer significantly higher wear resistance and a longer service life (6-12 months), reducing the cost of frequent replacements and minimizing operational downtime.
Diagonal hole plates are designed for efficient self-cleaning and higher accuracy, while parallel wave hole plates provide a higher opening rate for better screening effects and faster throughput.
For grading sizes 0.35-3mm, alloy steel is recommended for its high strength. For 0.35-1mm requirements where magnetism is a concern, non-magnetic stainless steel is the ideal choice.
Yes, they are specifically engineered for high-frequency screens used in coal washing and mining, providing the elasticity and strength needed to withstand harsh vibrations.
Our high-precision manufacturing process allows for a minimum aperture as small as 0.015mm, catering to extremely fine separation needs.
A higher aperture ratio (up to 43%) allows for faster material passage and higher throughput, whereas a lower ratio may be used to prioritize structural strength and specific precision.
