1.Refiner plate is the core part of the beating process of pulping machine  in paper and pulp industry.

2. It is used to improve the beating degree of pulp to satisfy the papermaking demand. This Refiner plate disc is suitable for various pulp, such as wood pulp, chemimechanical pulp, chemical pulp and waste paper pulp.

3.Material selection

High chromium cast iron, nickel chromium alloy, alloy, stainless steel, tungsten carbide are available. The optimized grinding tooth profile can meet the needs of specific process, to improve fiber beating quality,paper quality and reduce power consumption.
