Selection of drying equipment and examples of thermal calculation
(1) Known conditions: The temperature of the flue gas when entering the dryer is t 1 =800 ° C; Aluminum is one of the most commonly machined materials because of its excellent mechanical properties, some of which include softness, economy, durability, and corrosion resistance. CNC machine tools process aluminum profile workpieces with many processes such as milling, drilling, tapping, and CNC turning process. The precision aluminum machining parts produced are widely used in military, medical, aerospace, and industrial projects.

A beneficiation plant pyrite flotation concentrate was dried with a cylinder dryer.
The weight of the concentrate before drying is G 1 = 7000 kg / h;
The moisture of the concentrate before drying is W 1 = 16%;
The moisture of the concentrate after drying is W 2 = 6%;
The temperature of the wet concentrate before entering the dryer T 1 = 10 ° C;
The temperature of the dry concentrate when leaving the dryer T 2 = 90 ° C;
The nature of the air entering the furnace is t 0 = 20 ° C; ф 0 = 70%, I 0 = 46.47 kg / (kg K) from the Id diagram Id, d 0 = 10.42 g / kg dry air; 
The exhaust gas temperature discharged by the dryer is t 2 = 110 ° C;
