Ensure the feeding end of a negative pressure and inhale the high temperature gas produced by the burner to the sawdust dryer in time, to ensure which quickly exchange heat with the drying materials and put out timely,and then to lower the concentration of the waste gas as possible in order to achieve the purpose of fast drying. In the second drying stage, the temperature is 300℃,through the draughty fan to remove water, assure no coking, the third drying stage is 120℃-210℃,use the drum breaking device, hit again and again, the status is negative pressure low temperature and hot air by the draughty fan to remove the moisture.

The sandstone production line produce both of stones and sand ,which combine the stone production line and sand making production line.Our Fote Heavy Machinery machine experts will tell you the optimization process of wood chip dryer:

The selection of the ventilation and dust removal is the key of the optimization.Whether the quality of the ventilation and dust removal of sawdust dryer for sale good or not directly influence its production.So high production means choosing a dust catcher to deal with large amount of wind.Our Fote Heavy Machinery machine adopt the low temperature four stage drying under the condition of invariable lignite quality.The output lignite moisture will be below 13%.

In the first drying stage,remove the most of the moisture at 400℃ , assure no change of the lignite chemical composition and no easy to fire.With the technology advanced, the mining equipment has become more and more effectively.For rotary dryer, the output rate has increased obviously and the energy consumption has reduced largely. But the rotary dryer still have many problems, such as filling tube and dryers head easily burnt out, filling tube and dryers head easily burnt out, shorten service life of bag filter,leading the high cost of maintenance and affecting the normal production of the rotary drum dryer, and so on.
