The cooling machine is a heat exchange device, it is based on air as the medium through the high temperature of the clinker, then cooling the clinker, and at the same time recovering the heat of the exhaust gas as the kiln secondary, tertiary air and the drying air, improving the thermal efficiency of the kiln . But do you know which factor may influence the cooling effect of rotary drum cooler?
1, viscosity and thermal conductivity of matrix Liquid material, in a certain temperature range, the better the liquidity, the less the friction force of rotary drum cooler in the liquid material, the better the effect of heat transfer, the greater the coefficient of thermal conductivity in;
2, the metal materials thermal conductivity Different metal thermal conductivity coefficient, metal stuff with good electrical conductivity, thermal conductivity or;
3, metal surface finish Matrix viscosity at room temperature in 450 pa. S, contact with the wall would produce a strong adhesive.When the metal surface is rough on the surface will adhere to a substrate layer, wall surface is rough, adhesive layer is thick, continuing cooling, then this thing adhesive layer adhesion effect of rotary drum cooler is stronger, the thermal resistance is the adhesive layer and the metal wall thermal resistance, the sum of led to the decrease of the coefficient of heat transfer into the.
4, cooling column spacing of rotary drum cooler When a two column tube spacing far, between two tube center of matrix on the substrate temperature and pipe wall temperature difference is big, or small; Distance between a value is big, the substrate movement resistance is reduced, the opposite resistance increase. Distance between a factor not only consider the size of the temperature difference, coolant temperature, oil should also be considered when phase condensation temperature, substrate motion screw pump pressure factors such as the day;
As a famous rotary drum cooler supplier in China, In addition, they are professional cone crusher manufactures and cement mill suppliers, and hammer mill crusher for sale, etc,. If you have any other question or have an interest on our product ,you can write to us: sales@hxjq.com

वो जो हँसते हुए दिखते है न लोग
अक्सर वो कुछ तन्हा से होते है
पराये अहसासों को लफ़्ज देतें है
खुद के दर्द पर खामोश रहते है
जो पोछतें दूसरे के आँसू अक्सर
खुद अँधेरे में तकिये को भिगोते है
वो जो हँसते हुए दिखते है लोग
अक्सर वो कुछ तन्हा से होते है
