Why Sunco Machinery 7 Chambers rotary sand dryer is with better work performance ?

Time:2017年03月22日      Hits:

Here we will compare our 7 chambers design rotary sand dryer with the traditional single drum dryer.     

The traditional single drum dryer inner structure is like the below photo:

When the dryer is rotating, most of the sand is on the bottom of dryer drum, and it is difficult to be contacted and heated by the hot air sufficiently, thus its heat exchanging efficiency is low, and its natural gas consumption will be more higher.

For our new design Rotary sand dryer with special 7 inner chamber, it is like the below photo:

When our 7 chambers rotary sand dryer is rotating, the sand is dispersed into all the above 7 chambers, and the sand moving situation inside the dryer is like the below photo which is taken at our factory when we made a test run of our 7 chambers designed dryer without opening the burner and draft fan/blower and just to see the moving situation of raw material when only the dryer drum is rotating.

As you see, in each chamber of the sand dryer drum, there are welded guide plate (Lifting Plates) which flip the sand continuously, 

(a)The traditional single drum dryer only flip the sand one time, our new designed 7 chambers dryer flip the calcium carbonate 7 times.

(b) The sand layer thickness in our new designed 7 chambers dryer is about 1/7 of the sand layer thickness in the traditional single drum dryer.

(c) All the 7 chambers of our new designed 7 chambers dryer have sand when rotating, and the weight of each part of our dryer is even / balance, and the dryer can rotate smoothly and stably.

As a result, for our 7 chambers designed rotary sand dryer:

The contact area between the hot air and the sand is more, and the heat exchanging efficiency is higher, and then the Natural Gas Consumption will be lower than the traditional single sand drum dryer.
