2025.12.08
All boiler feed pumps at Daio Paper Kani Mill are now manufactured by Torishima [Orders Received in July 2025]
Daio Paper Corporation’s Kani Mill is a major production base second only in scale to the Mishima Mill, where the company’s headquarters are located. It is a vast factory covering approximately 300,000 m2. It manufactures pulp from plantation wood chips and recycled paper, producing a wide range of paper products through integrated manufacturing, from everyday household items to industrial-use papers. Daily production capacity is approximately 1,200 tons of pulp and 1,010 tons of paper. It produces the largest volume within the group of Elleair brand tissues and
toilet paper.
The mill generates approximately 80% (about 60,000 kWh) of the electricity required to operate its production equipment through on-site power generation, driven by two recovery boilers (2RB and 3RB), one sludge boiler (4SB), and one biomass boiler (6BB).
The boiler equipment (2RB), for which the renewal of the boiler feed pump has been ordered, recovers and reuses black liquor (a mixture of chemicals and wood components) generated during the pulp cooking process*, to efficiently reuse the heat from steam and waste liquid and achieve high energy efficiency.
The existing pumps manufactured by another company had progressing component aging due to long-term operation, leading to frequent breakdowns and troubles, as well as increased maintenance costs. In response to this situation, Torishima made a renewal proposal, which led to this order.
In addition to the two boiler feed pumps of 2RB No. 1 and No. 2 from this project, the mill already uses other boiler feed pumps manufactured by Torishima that receive regular maintenance. The trust of the customer was built by Torishima’s service representatives (SV) and high evaluation of our products and support, as well as the introduction of the vibration monitoring system TR-COM. This trust contributed to the selection of Torishima pumps for this project. As a result, all boiler feed pumps at the Kani Mill will now be Torishima products.
We will continue to contribute to stable mill operations through high-quality products and services, striving to meet our customers’ expectations.
* Pulp cooking process: The process of boiling wood chips with chemicals to extract fibers for producing pulp, the raw material for paper.
