Natural gas heat source of river sand/silica sand roation drum dryer

== river sand/silica sand roation drum dryer Brief description

Riversand dryer/sludge drying machine/mud drier for sale is one of the newly developed and unique principle dryer which combined with the working principle between the three cylinder rotary dryer with dip angle and airflow drier. After continuous improvement, it has been reached the international advanced level, not only can deal with low viscosity and high moisture materials but also viscous larger and high moisture materials. It overcomes bulky of the traditional silica sand dryer and larger cover area of air flow dryer, with small size, high thermal efficiency, light weight, wide applicability, flexible temperature control and so on.

[Factory Brief Introduction]

Henan Dingli Drying Equipment Co.,Ltd,located at No.59,Dongda Street,Guancheng Dist.,Zhengzhou,China.We are the expert and the biggest factory of  manufacturing various drying machine equipments as rotary drum dryer,coal dryer,mining drying machine and biomass dryer,applied for coal,wood,biomass,manure,food,grain,decoction,straw and others,equiped with conveyor, crusher or grinder,heater or burner,dust collector or removing,pellet mill and packing machine. 

== river sand/silica sand roation drum dryer Structure and Working principle 

Material goes through the feeding device into the lining of the drum, in order to realize the downstream drying, material inner constantly grabbed, scattered under the copy board of a spiral rolling to realize heat exchange, the material move to the other side of the lining and into the middle side, at this time going counterflow drying, material in the middle are constantly repeated by copy board, it is marching into two steps forward and one back, material in the middle is fully absorb heat coming from the inner cylinder, and absorb the middle roller heat and prolong the drying time again at the same time, at the moment dry material is at the best condition. The Material go to the other side of the middle section and into the outer section, material within the outer cylinder in rectangular loop travel , in order to achieve the material moving fast to discharge roller under the effect of drying in hot air . Because of the weight other wet material can't advance rapidly drying, the material returns to this rectangular copy board with fully drying action, in this way offer machenical riversand drying machine and sludge or mud dryer can achieve purpose of drying.

==  Reliable technology of river sand/silica sand roation drum dryer
1. The earliest silica sand dryer technology was from Germany, which is composed of three concentric rotating drum, material at head of the tube goes into the inner cylinder, under the action of copy plate the material back to the middle barrel, once again back to the outer barrel, finally dry material is discharged from the other end of the barrel, the length is three times as that of the traditional dryer, thus it greatly reduced the volume of the equipment.
2. Rotation speed controlling system can be adjust according to the different materials , little abrasion, safe and reliable, low maintenance cost.
3. The feeding speed can be adjusted,simple operation.
4. Large capacity, continuous operation of offer machenical riversand drying machine and sludge or mud dryer .
5. Advanced explosion-proof fire system design, safe and convenient.
