Assesment [sic] Assessment of process parameters on pellets' quality using different raw materials

Abstract

During this research two raw materials are investigated sawdust and Lebanese olive residues in order to find the optimum conditions at which the pellets process occurs. In addition to the creation of new type of hybrid pellets that combine the advantages of both raw materials, where the obtained pellets from the raw materials mixture will have better characteristic than each separately. In order to achieve this objective, many analyses were done on both raw materials in terms of density friction and PIN Test. More than 700 experiments were done on the universal test machine (UTM) for both friction test and PIN Test. The friction test necessitated a modification of the UTM. Once the behavior of both raw materials is known under different test conditions, a series of ratios (Abou Haidar Ratio: {cedil}{9D}{90}{thorn}{cedil}{9D}{90}{BB}{cedil}{9D}{91}{85}) and a procedure (Abou Haidar procedure: {cedil}{9D}{90}{thorn}{cedil}{9D}{90}{BB}{cedil}{9D}{91}{83}) are proposed in order to optimize the manufacturing of pellet mill machine and calculate the power needed for the use of Sawdust, Olives Residues and the mixture of both in three types of pellet mill machines (Flat Die Machine, Inner Ring and outer Ring Die Machine). A deep analysis on each type is done as well s as comparison between the three types, and more than 15 tests are done on different raw materials condition to achieve the optimum conditions for the pelletizing process.
