2017 Hot selling Silica Sand Dryer/Sand dryer machine/Quartz sand drying machine with three cylinder

 Three cylinder silica sand dryer is widely suitable for all kinds of powder, the massive materials, sheet materials and variety of slag and dregs material, such as ore,ore powder, iron ore,brewer's grains, alcohol dregs, pomace, medical residue, sauce residue, sugar dregs, wood chips, etc.

Our company professional to research of the silica sand dryer, three cylinder dryer is one of the newly developed and unique principle dryer which combined with the working principle between the rotary drum 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 rotary drum 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.

Structure and Working principle of silica sand dryer:

The Wet 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 counter-flow 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 it can achieve purpose of drying.

 Technology features and advantages of silica sand 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.
5.Advanced explosion-proof fire system design, safe and convenient.
