The Use of Thermography to Determine the Compaction of a Saddle-Shaped Briquette Produced in an Innovative Roller Press Compaction Unit

Abstract The unit compacting pressure in the fine-grained material consolidation process roller press can reach >100 MPa and is a parameter that results, among other things, from properties of consolidated compaction geometry. Achieving right during briquetting one factors guarantee proper quality briquettes. distribution temperature on surface briquettes correlates with locally exerted pressure. present work aimed to analyse four materials equipped saddle-shaped briquette-forming rollers based images obtained thermography conducted immediately after their consolidation. tests were carried out was forming 450-mm diameter having cavity volume 4 cm 3 , as described by patent PL 222229 B1. Two mixtures hydrated lime 9.1 wt% 13.0 water, mixture scale electric arc furnace (EAF) dust used for tests. In most mixtures, highest temperatures achieved middle-upper part EAF heated up 37.7 °C. difference between maximum briquette ambient 20.2
