Abstract

When considering the operation of roller presses for the consolidation of fine-grained materials, the main problems are disturbances in the proper flow of the material and its bridging in gravity feeders. This is especially true for small and medium capacity presses, where the hoppers for dosing the material are narrow. This article presents innovative laboratory tests of the impact of using a polymer plate lining in the gravity feeder of a roller press. Polymer materials Polyacetal C (POM C) and Ultra-High-Molecular-Weight Polyethylene (UHMW-PE) were used for the tests. The influence of the use of plates on the material flow and quality of briquettes was investigated in comparison with the case where such plates were not used. The research showed an improvement in the flow of fine-grained materials in the feeder and an increase of the briquette strength indexes, as compared to those cases when polymer linings were not used in the feeder.

摘要

在考虑使用辊压机压实细颗粒材料时，主要问题是物料正常流动受到干扰以及在重力给料器中出现架桥现象。对于中小型压机而言尤其如此，因为这些压机用于给料的料斗较窄。本文介绍了在辊压机重力给料器中使用聚合物板衬里所产生影响的创新性实验室测试。测试使用了聚合物材料聚甲醛C（POM C）和超高分子量聚乙烯（UHMW-PE）。与未使用此类板的情况相比，研究了板的使用对物料流动和压块质量的影响。研究表明，与给料器中未使用聚合物衬里的情况相比，给料器中细颗粒材料的流动性得到改善，压块强度指标有所提高。
