盘磨机磨片的设计理论与方法

Design Theory and Method of Disc Refiner Plates

盘磨机是目前广泛使用的磨浆和打浆设备,磨盘(或磨片)是盘磨机的核心部件,虽然盘磨机磨浆(或打浆)技术已经比较成熟,但仍存在着功耗大、磨片使用寿命较短等问题。盘磨机的功耗、打浆质量、磨片使用寿命等均与磨片设计有密切关系。本文从盘磨机的功率消耗的计算、磨浆或打浆机理研究、磨片齿形设计理论和方法、磨片的材料选择与使用寿命四个方面介绍了盘磨机磨片设计理论与方法的研究进展与应用现状,并且进行了分析与展望。本文的工作对于盘磨机设计、研究、应用和性能改善等具有重要的意义。

Disc refiners are used in refining and beating widely, the plate is a key unit of a disc refiner. Although refining and beating technology is relatively mature now, there are still some problems such as great energy consumption of disc refiners and the short service lives of the plates, the design of disc refiner plate is intimate with energy consumption and refining or beating quality. the main purpose of the paper consists in introducing the progress of study on the design theory and method on disc refiner plate from four aspects： energy consumption equations, the research on refining or beating theories, the design theory and method of plate teeth, material selection and its service life, and prospects has been also discussed in the paper, the work of the paper is significant to the design and study of disc refiner, as well as the application and performance improvement of disc refiner.
