Disc Refiner Sizing & Net-Energy Estimator

A first-pass estimate of plate diameter, motor rating and net refining energy from your line throughput and furnish. Diameter and rotor speed run inversely (UBC FineBar chart); net energy bands are furnish-specific. Final specification is confirmed per order.

Estimates use industry-grounded envelopes (net energy bands: UBC fibrelab / IPPTA; diameter↔rpm: FineBar chart) and assume ~80% drive efficiency + ~30% no-load headroom on motor sizing. They are for planning only — Henan Zejiang Paper Machinery confirms plate pattern, exact motor and capacity against your stock and target freeness on quotation.
