The analysis is focused on the pneumatic momentum, mass, and heat balance of the solid particle when it moves inside the reactor. A fixed bed fluidization model was used to calculate the forces balance on the single solid particle. By solving mass and heat balance occurred in the particle, the water/liquid removal efficiency can be calculated. To validate the model calculations, we conducted a set of experiments and compared the simulation with the experimental data. High-moisture, natural concrete sand, the additional material for portland cement, was used and dried along a vertical cylindrical tube with length of 2 m and diameter of 6.68 cm. The drying gas was supplied by a high-capacity air blower which was connected to the burner to produce 120 m3/h of drying gas with maximum temperature of 800C.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Heat balance,Pneumatic drying,Pneumatic momentum,Pneumatic transport[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Mass-heat balance,Pneumatic drying,Pneumatic drying model,Pneumatic transport[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1080/08916150701418252[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
