Industrial Ceramic Products For The Papermaking Industry
Industrial Ceramic Products For The Papermaking Industry with wear resistance
Ceramic parts are effective for separating foreign materials and dewatering.With their superior wear resistance, ceramics are used to create cleaner cones that separate foreign material from pulp slurry, suction box covers, and blades to dewater through a wire mesh, as well as flat parts and rollers to remove water from felt.
