Roller presses are most common pelletizing and compacting machines for fine-grained materials in metallurgy and related industries. Rollers with replaceable tires, whose effective surfaces are equipped with molding elements, are major components that directly exert a force on the material being compacted. The press surface configuration significantly influences the compaction conditions and the quality of pellets. Analysis of information sources shows that there is currently no single systematic approach to choosing the rational surface configuration for roller press tires. A large number of process and service parameters indicates that the choice of rational surface configuration for press tires should be based on multivariate analysis methods. Therefore, a systematic approach to the choice of rational geometrical parameters for roller press tires and a method that implements this approach have been developed. The method represents the problem in question as a three-level hierarchy: options for the design of tires, criteria to evaluate the rationality, and the most rational tire design. A specific example demonstrates how the proposed approach is applied to choose the configuration of pressing surfaces to promote the required parameters of charge compaction, the tires having the longest possible service life, and ensure that the press is operated within its technical characteristics. The proposed systematic approach and the method developed to implement it allow the geometrical parameters of press roller surfaces to be compared and evaluated for rationality at the design stage. The results can be used as a constituent part in the development of specialized software for the calculation and design of roller presses.

选择合理的表面配置 用于辊压机轮胎

辊压机是冶金及相关行业最常见的用于细粒材料的造粒和压实机器。带有可更换轮胎的压路机，其有效表面装有成型元件，是直接对被压实材料施加力的主要部件。压机表面配置显着影响压实条件和颗粒的质量。对信息来源的分析表明，目前没有单一的系统方法来选择辊压机轮胎的合理表面配置。大量的工艺和使用参数表明，选择合理的压榨轮胎表面配置应基于多元分析方法。所以，已经开发了一种为辊压机轮胎选择合理几何参数的系统方法以及一种实施该方法的方法。该方法将问题表示为三个层次：轮胎设计选项、评估合理性的标准以及最合理的轮胎设计。一个具体的例子展示了如何应用所提出的方法来选择加压表面的配置，以提高装料压实所需的参数，使轮胎具有尽可能长的使用寿命，并确保压力机在其技术特性范围内运行。所提出的系统方法和为实现该方法而开发的方法允许在设计阶段比较和评估压辊表面的几何参数的合理性。
