<p>Rotary dryer can dry many kinds of materials which contain moisture, not to say ordinary materials such as coal, coal slurry, slag, industrial waste, and clay stone. It could also dry those materials that could not have contact with iron or corrosive, such as silica sand, glass product materials etc. Fote drying machines has been exported to Indonesia.</p><p>The following we will share five problems and the corresponding methods of rotary dryer:</p><p>1. The wind speed is too low which lead to contact dynamics loose between the material and the dynamic &amp; static hot wind and the rotary rotary dryer efficiency is much lower.</p><p>2. To raise the output makes the inlet temperature and the outlet temperature over high which lead to the waste of energy and the quality of material being dried decreased, the color and luster go black, and there are many paste material.</p><p>3.The material cannot make “alternating motion” in the rotary rotary dryer, and so the material in the rotary dryer will be taken out by wind which leads to the low material storage quantity in the rotary dryer, thus the contact area between the material and the dynamic and static hot air decreases.</p><p>4.To limit the material way out direction’s flow speed, the rotation speed of the rotary rotary dryer should be kept very low. Thus the elevated times of the material in the rotary rotary dryer are greatly decreased. So the contact times of the material and the hot air are greatly decreased.</p><p>5. There is only fair current drying, and the saturated steam cannot discharge timely in the drying process. So the steam moves a long distance in the rotary dryer which leads to the moisture reabsorbed by the dry material. high pressure grinding mill.</p><p><a href="http://www.ft-dryer.com/">Rotary dryer</a>s are the most commonly used wood drying system in the particleboard industry. These dryers also play an increasingly important role in drying wood residues for fuel. Many potential benefits may be realized through an improved understanding of the rotary drying process. </p><p>crusher mobile: http://www.fote-machine.com/product/rub … </p>
