Agglomeration of straw and hard coal with an additive of potato pulp - experimental study
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 1
Abstract
The paper presents experimental investigations on pressure agglomeration of straw with 20% hard coal addition at various potato pulp contents and at varying process temperatures. Compaction was carried out on a laboratory stand with an open compaction chamber. The experiment was performed at potato pulp contents of 15, 20 and 25% and at temperatures of 40, 50, 70 and 90°C. The effect of densification temperature and potato pulp content on medium and maximum compacting pressures, average compaction force, compaction work and density of obtained granulate was determined. The use of the binder and increase the process temperature have resulted in a reduction in the value of maximum agglomeration pressures and a reduction in the density of the obtained pellets.
