A rotary dryer is a type of industrial dryer used to reduce or minimize the liquid moisture content of the material by bringing it into direct contact with a heated gas. These dryers are made up of a large, rotating cylindrical tube that is typically supported by concrete columns or steel beams. As we all know,in the world, everything isn"t perfect.T here is no one exceptional. Rotary dryer,as well as some other things in the world, when we"re using the rotary dryer to deal with raw materials,there will be some shortcomings. Now, I will list a few ones.1.Wind speed is too low in the roller, causing the material and hot air static and dynamic contact strength flabby, resulting in low efficiency of the rotary dryer.2.Material in the roller will not be in a reciprocating motion,so the materials in the roller will soon be wind pumping away,resulting in the material storage in cylinder too low, causing material and hot air static and dynamic contact area reduced.3.In order to improve the yield,the dryer roller is too long to do,and the diameter is too big.Can"t be made full use, then cause heat loss; What"s more,the rotary dryer"s covering area is too large;4.In order to improve production,the import and export temperature is too high,causeing energy waste,as well as cause the dried material quality drop; Material colour is serious black,evenly a lot of paste.5.The tilted installation of the rotary drum dryer host"s fire entry high and end of the fire low is a extreme mistake.Because the installation method can only speed up the material flow to the end of the fire, which make the material storage within the cylinder reduce again;6.In order to limit the speed of material flowing to the export direction ,so the roller rotating speed can only be at a low limite,then the material being lift frequency is greatly reduced.This causes the material and hot air dynamic contact times is greatly reduced.coal ash dryer manufacturer:...
