CNBM Paper Pulping Machine Advantage

CNBM manufactures paper pulping machines and builds pulp production lines cover the pulp cooking, pulp washing, and pulp bleaching process. Through continuous technology improving and careful selection of construction materials, CNBM paper pulping machines have achieved multiple advantages including low energy consumption, small noise, high production efficiency, compact size, easy to operate, etc.

CNBM also developed the super batch cooking system to replace the conventional cooking system used in pulp cooking process. Its annual output reaches 300,000 tons and it considerately reduces energy consuming and waste discharging compared with the conventional pulp cooking system.

paper pulp cooking process

Pulp cooking process is where the main part of the delignification takes place. Here the wooden chips are mixed with white liquor, heated to increase the reaction rate and then disintegrated into fibers by ‘blowing’ – subjecting them to a sudden decrease in pressure.

paper pulp washing process

In pulp washing process, because of the high amounts of chemicals used in the cooking wood in Kraft pulping, the recovery of the chemicals is of crucial importance. The process where the chemicals are separated from the cooked pulp is called pulp washing process.

pulp bleaching process

Pulp bleaching process involves removing virtually all of the lignin that still remains after paper pulp cooking, as the lignin contains the chromophoric groups which make the pulp dark. Pulp bleaching process has two steps: oxygen delignification and final bleaching.
