Leading expert in paper pulping industry since 1968.
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.
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.
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 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.

Bleaching equipment plays a crucial role in the paper making process. It is used to remove impurities and color from the pulp, resulting in a high-quality paper product. Bleaching equipment can come in different types and sizes, each with its unique functions and best practices for optimal performance. In this article, we will discuss the
In the papermaking industry, the efficiency of the dewatering process plays a critical role in determining the quality and cost-effectiveness of the end product. Pulp consistency, the amount of solid content in the pulp, is a key factor that impacts dewatering efficiency. Understanding the relationship between pulp consistency and dewatering efficiency is essential for optimizing
The pulp cooking process is a critical step in the production of paper and paperboard products. It involves the breakdown of wood chips or other raw materials into pulp using chemical, mechanical, or a combination of both processes. The quality and efficiency of the pulp cooking process are largely dependent on the equipment used. In
