2021-11-25

Recently, the overall optimization and speed-up renovation project of PM3 paper machine in Zhaoqing Zhongsheng Paper Industry, undertaken by Big Finger Equipment, was successfully started up. The overall operation effect exceeded expectations and was highly praised by users. At the same time, it also announced that Big Finger Equipment added a successful case of the quality and consumption-reducing renovation project of the whole machine in the South China market.

PM3 is a long-net multi-cylinder cultural paper production line with a width of 2640mm and a design speed of 600 m/min. It mainly produces 60-150g/㎡ high-grade cultural printing paper. It has been running for many years and has many problems, resulting in low production efficiency, high steam consumption and low product quality.

Line pressure fluctuation in press section
Long open distance, many paper diseases, easy to break the head
Gear box transmission noise, oil leakage and vibration
The steel wire roller sizing machine has low operating efficiency and is prone to streaks
After on-site investigation and detailed communication with customers, the two sides confirmed the following transformation plan and put it into practice, with remarkable effect.
The press department replaces the new hydraulic and control system to stabilize the line pressure.
Adjust the position of the guide roller, optimize the geometric angle of the press section, and improve the paper feeding efficiency.
Replace DST scraper to improve dehydration effect
Before increasing positive pressurePressnip web stabilizerReduce paper disease and improve operating efficiency.
Changed gear box driveGuide roller silent drive
The second baking is changed to single hanging, and a paper stabilizer is added.
dryerAdded spoiler rod deviceImproved drying effect
Old-fashioned steel wire roller sizing machine changed to more advanced structureIntegra®-Sizer film transfer sizing machine and modification of the feeding station system

"From the preliminary plan exchange to the subsequent implementation of the big finger equipment, relevant professional technicians are responsible for docking, and tailor-made design of the most cost-effective implementation plan for our machine. In addition to the film transfer sizing machine, big finger company mainly provides key equipment similar to DST scraper, paper stabilizer, guide roller drive and other key equipment with small investment but immediate effect to improve the operation performance of the paper machine according to the problem characteristics of our machine, this fully demonstrates their company's rich experience in transformation. After the transformation, the paper sheet operation efficiency of the press department and the drying department has been significantly improved, and the paper disease problems, noise and oil leakage problems have also been effectively solved. The film transfer sizing machine of Dazhi Company is more automated and easier to operate than the previously configured sizing machine. I think the overall transformation effect of the project is very successful, and I am full of confidence and expectation for further cooperation between the two sides in the future"

Chen Xuewen, Deputy General Manager
