在现有的文献中,对共振运输机和共振筛理论的研究都引入了这样一个基本假设:把运输槽中或筛面上被输送或被筛分的物料质量的一部分加于振动槽或筛箱质量中,从而引出一个常值的“计算质量”。生产实践表明:工艺负荷的变化是引起共振运输机和共振筛振幅变化的主要原因之一。因此,精确地描述物料对运输机和筛机系统的作用和影响是必要的。本文力图在这方面作些初浅的探讨,愿起抛砖引玉之效。物料在运输槽面和筛面上只受有单面约束。根据波列赫曼等人的理论,物料在槽面或筛面上
In the current literature, the study of resonance transporters and the theory of resonance sieves introduces the basic assumption that a portion of the mass of material being conveyed or sifted in or on the conveyor chute is added to the shaker or sieve box Quality, leading to a constant value of “calculated quality.” Production practice shows that: the change of process load is one of the main reasons that cause the amplitude change of resonance conveyor and resonance sieve. Therefore, it is necessary to accurately describe the effect and impact of material on the conveyor and screening machine system. This article tries hard to make a shallow discussion in this respect, is willing to serve as a starting point. Materials in the transport slot and screen surface only by the single-sided constraints. According to Perrierman et al’s theory, the material in the groove or screen surface
