Early refining equipment used was the pulper used in the paper industry. The pulp fibers defibrated by the pulper have excellent shape, but due to low productivity, they are no longer used in the artificial board industry. In the production of soft fiberboard, the water filtration rate of the pulp needs to reach 60-100 seconds. Some factories use cylindrical refiners to achieve good separation effects. Currently, the disc refiners used in most wet fiberboard factories have the same structure as thermal refiners, but without the wood chip cooking part, they rely on adjusting the gap between the grinding discs and the pulp concentration to control the quality of fine grinding.
