Medium strength pulping technology

The vast majority of beating workers and researchers engaged in the beating process have long realized that increasing the beating concentration will greatly improve the beating effect. However, for a long period of time, there is no suitable medium and small size paper mill in China. The medium-strength beating equipment that can be widely used makes the beating process in our country limited to 3%-4% of the low-level beating state.
The Zhongnong hydraulic disk mill developed by this engineering center can operate at a concentration of 6%-15%, providing a reliable way to change the low-strength beating state of China's papermaking process. Zhongnong Hydraulic Disc Mill is a new type of high-efficiency and energy-saving pulping equipment. When it is beaten at a concentration of 6%-8%, it is obviously compared with the traditional low-strength beating (3%-4% concentration) beating equipment. Superiority:
●It can save 30% - 40% of the electricity consumption of ton pulping;
● The physical strength of slashers is increased by 10% - 35%;
● Toner pulping water consumption saves more than 50%.
Traditional pulping equipment, due to structural limitations, can only be operated at a low concentration of 5% or less, with high concentrations, which can cause poor flow and even blockage. The pulping at such a low concentration results in high power consumption, frequent cut-off of the fibers, rapid wear of the plate, and a large amount of noise. Zhongnong hydraulic disc mill can operate in a relatively high concentration (6%-15%) due to its special structure and advanced design. The beating action of fibers in the grinding zone mainly depends on the friction between fibers. The changes in fiber morphology, the cutting effect is less, the disentangling is stronger, the average fiber length is obviously improved, and many defects of low-strength beating are effectively overcome. The new process of medium-beating pulping has practical value for reducing papermaking costs, improving product market competitiveness, and adapting to the ever-changing production requirements of products. Medium-strength beating technology is also one of the key technologies for the development of China's paper industry.
