Frequently asked questions

How does screen size affect grinder capacity?

Smaller openings usually increase recirculation and can reduce throughput. The result also depends on material, rotor and feed conditions.

Can one screen work for every material?

No. Moisture, density, contamination, target output and downstream use can require different openings or screen construction.

What information is required for a parts quotation?

Provide the machine model, serial number, clear photos, installed assembly details, dimensions, required quantity and processed material. Compatibility is confirmed before quotation.
