Fuel consumption is one of the key factor for the rotary sand dryer. Below we will explain the fuel consumption of the rotary sand dryer in detail.

For the rotary dryer, according to the past experience, to evaporate one ton water into vapour needs about 600000 kilocalorie.

For example, the input moisture content of sand is 30%, output moisture content of the sand is 2% , fuel is natural gas (Heat value of natural gas is 8500 kilocalorie per m3), processing capacity of sand dryer is 2 t/h.

Then, every hour the sand dryer needs to evaporate the quantity of water is : 2- (2x70%)/98% = 2-1.42857=0.57 ton.

As a result, every hour the quantity of natural gas to be used is : (0.57 x 600000)/8500=40.3 m3.

The above calculation is just for reference, the real fuel consumption shoud be according to the actual situation of the raw material , environment temperature, etc.
