Three cylinder sand dryer have a very good drying efficiency in the wet raw material drying equipment series.This three drum sand dryer machine is based on single tube rotary dryer improvement of high efficiency and energy saving products. After many companies and industries’  application ,this three cylinder sand dryer machine have a very good drying effect .

The hot air and sand raw material in the three cylinder going direction as below

 Three rotary drum sand dryer improved and design the internal structure on single drum dryer, this three cylinder sand dryer structure increase the drying effect before the wet material into the machine and prolong the drying time of the wet material in the dryer machine,this dryer machine also add seal,the heat preservation and other reasonable supporting measures, this make this sand dryer drying capacity improve 50-80% than single drum dryer, Unit water evaporation intensity can increase to 120-180 kg/m3, the coal consumption only is 6-8 kg drying one tone material. This three cylinder dryer use advanced technology, the drying operation parameters is reasonable , operation is simple and feasible. It widely used to many industries of drying sand, quartz sand ,slag, clay, coal ,iron powder, mineral powder and other mixing material.

The advantage of the three-cylinder sand dryer:

1.The sand dryer principle is scientific and reasonable,also is high efficiency and energy saving drying equipment. Material in the dryer cylinder for heat transfer with hot flow in the form of radiation, convection and conduction,outer tube heat transfer in the form of conduction and convection.

2.This sand dryer high thermal efficiency,energy saving is very remarkable.After the examination, the level of thermal efficiency is about 50% more than traditional dryer . The equipment after working, the production of the energy saving effect is remarkable.

3.The sand dryer the material and heat flow downstream drying process,it widely application to drying river sand,quartz sand,clay,coal,slag,ore powder and other material ,this three cylinder sand dryer also can be used drying the material of metallurgy,chemical engineering and other industry. This rotary dryer design with compact structure, The whole dryer use machine horizontal layout, adopt roller bearing support, this design cancel the transmission of big and small gear,instead of riding wheel drive, this make the installation more convenient, operation more simple,dryer working is more reliable, operation rate is higher.

4.The external surface area of this sand dryer is reduce more than 30% than the single tube rotary dryer, also the external cylinder to internal cylinder have heat preservation and heat insulation effect, this reduce the heat lost,at the same time of High Efficiency and Energy Saving, Greatly improve the working environment and working conditions.
