Twin Roll Press

CNBM Anyang Machinery Twin Roll Press is a high-pressure, high-concentration device designed for pulp washing, utilizing displacement and squeezing effects. It has gained widespread use due to its ability to extract black liquor at high concentrations and temperatures. For chemical pulps and mechanical pulps with lower freeness, shorter fibers, or higher consistency, the Twin Roll Press can effectively wash and concentrate the pulp at medium to low concentrations.

CNBM Anyang Machinery Twin Roll Press consists of several components, including a dewatering roller, a pulp tank, a pulp discharge system, and a sealing mechanism. During operation, the rotation of the dewatering roller causes the pulp to pass sequentially through the dewatering zone, displacement zone, and squeezing zone, achieving thorough washing and concentration of the pulp.
