Hello, friends! I am Sensen Wang, a reporter from China Magazine Papermaking. Today, we are at the scene of the 2025 China International Paper Science and Technology Exhibition. We have now arrived at the booth of Zhengzhou Yunda Paper Machinery. Today, we are fortunate to meet General Manager Xu. Hello, General Manager Xu! Could you please introduce the development of Yunda over the years and your main core competitive products?
Yunda this year has been 44 years of history, has been deeply involved in the papermaking pulping equipment industry. Our pulping and papermaking equipment covers several major production lines. The first is tissue paper pulping equipment, the second is waste paper pulping equipment, and the third is complete production lines for CTMP. Additionally, we also produce spare parts and provide preliminary consultation and maintenance services, such as the maintenance of high consistency refiners and drum pulpers, offering professional industrial services to contribute to China's and the world's papermaking industry.
OK, General Manager Xu! I see you have brought many products to the exhibition. Could you please introduce them?
The products we are exhibiting primarily include our high consistency refiner, which is mainly used for CTMP and high-yield pulp. Over here is our screen basket, this is the Oda screen basket, known for its reliability, energy efficiency, and high performance. It is also one of our industrial service spare parts products. Additionally, we have our waste paper pulping equipment. This time, we have brought the largest rotor for waste paper disintegration. This is the 13.5DR model, with a daily production capacity of up to 1,500 tons. These are the main products we are showcasing at this exhibition.
Moreover, we provide maintenance and renovation services for paper mills. So far, we have maintained 39 high consistency refiners and renovated 36 drum pulpers. Industrial services for paper mills will remain one of our main business focuses in the future.
Great! Thank you, General Manager Xu.
