Pulpers

Pulpers are available in sizes from 6’ to 24’ diameters for low, medium and high consistency pulps in continuous or batch production.

A pulper is a sturdy stainless steel tub, incorporating 4 baffles that aid the agitation of the stock, and prevent mass rotation. A stainless steel 8 bladed rotor is used for most applications, but medium or high consistency rotor can be used. the 8 bladed rotor is designed to rotate with minimal clearance above the screen plate, forcing stock through it. Fibres too large to pass through are cut by attrition between the rotor and screen plate bars to be accepted. Large impurities are retained in the pulper tub to be removed by pulper cleaning equipment. 

The pulper tub and baffles are fabricated in 8mm thick stainless steel, with three external RSC strengthening rings reinforcing the tub. All other contact parts are stainless steel. All rotors are mounted on forged EN8 hubs that are carried on an EN8 driveshaft, mounted on spherical roller bearings, housed in a heavy duty fabricated mild steel cartridge. The whole assembly is mounted on a robust mild steel leg assembly, giving a stable platform for pulper operation. A motor base plate incorporating a jacking arrangement and V-belt sheaves are designed to give optimum operating speeds from a customer motor.
