The Purpose of Optimizing Refiner Plate
Beating is a simple and crucial step in the paper making production process. Due to its simplicity, it leads to neglect of management and technology, resulting in low actual utilization rate of refining machine, unreasonable matching of disc refiner plate teeth, high power consumption, and waste; The “key” is that the beating method and the adaptability of the refining machine model, refiner plate tooth type, etc. have a very important impact on the beating indicators and paper machine paper making, and often affect the established indicators of the finished paper. Disc refiner plate is the “core component” of the pulping machine. Whether it is a conical refiner, a double disc refiner, or a middle consistency refiner, each model and specification of the refining machine has several to dozens of different refiner plate tooth types to choose from. Different pulp, paper types, processes, and indicators require the selection of suitable tooth types of refiner plate. The design and selection of refiner plate tooth types will directly affect the quality and efficiency of the refining machine. In the future paper production, there will be more diversified requirements for pulp fiber indicators. Therefore, optimizing the design and selection of refiner plate and pulping methods to ensure pulping quality and fully utilize the efficiency of the refiner is of great significance. Optimizing refiner plate is also an innovative behavior to reduce internal friction and improve economic efficiency in paper making enterprises, which should be taken seriously by the industry.
Differences and Effects of Pulping
The differences in pulping methods or the selection of refiner plate can lead to different pulping indicators and fiber properties, and also affect the adaptability of different paper machines for paper making. Refining optimization includes fluid equipment selection, pipeline layout, number of activated refining equipment, series and parallel forms, refiner plate selection, refining methods, etc. The optimization of refining methods includes refining concentration, power distribution, pressure control, flow control, temperature control, etc. Refining accounts for a high proportion of electricity consumption in the paper mill, but because the refining process accounts for a small proportion of the entire paper mill process and the equipment form is relatively simple, managers often ignore the refinement and optimization of the refining process in the refining section, resulting in high refining energy consumption, unstable refining indicators, and fluctuations in paper quality.
The Impact of Refiner Plate Tooth Profile Optimization on Pulping
The combination of refiner plate tooth profile optimization and refining method adjustment is a simple and effective way for paper enterprises to reduce consumption and improve efficiency; The selection of refiner plate has a direct impact on the beating index, and choosing different refiner plate tooth types for different beating processes is a prerequisite for optimizing beating; Optimizing and adjusting aspects such as pulping pressure, throughput, and pulping current can enable pulp to have different filtration speeds and properties.
