cow dung dryer machine is Dingli company according to the market demand professional design and developed one type new rotary dryer,this new type dryer suitable to drying the material moisture content at 50-65%,such as cow dung,chicken manure, poultry manure,sawdust,wood powder,wood chips,wood shaving,barley straw,oat straw, wheat straw,rye straw,rice straw, broom corn straw,The peanut vine,corn straw and other material.Depended on the different characteristic of each type of raw materials, different capacity, application requirements, cost control, automation degree, optimize the drying process technology,working conditions on site and other things,we can design the drying process.Dingli Company recommended product:this cow dung rotary drum dryer unit capacity is larger,high efficient,saving energy,covers area is more less, it can saving energy more than 50% than ordinary dryer,it can maximize saving energy and drying costs.

Drying process of cow dung rotary dryer:

 Working principle of poultry manure rotary dryer:

Moisture content 50-65% raw material put into mixing drum dryer by a screw conveyor for downstream drying, the material will be constantly lifting by lifting plate, then Scattered in a spiral type marching forward,this type dryer is equipped with a high -speed broken devices in the roller, it can fully mixing scattered and broken the material, the material and hot air will heat exchange, the water will quickly evaporation and gasifier, the material which achieved the drying effect will be quickly moving and fast discharge under hot air action, other material which not achieved drying effect will moving slowly under self weight,the material will fully dry inside of drum ,have a good drying effect and complete the drying process,and put out by screw conveyor. Inside of this type drum dryer is equipped with shaking and cleaning devices, this can prevent material adhesive on dryer body.

Gas flow as below:

the air by the blower add pressure into the hot stove burning to heat, when the temperature reached 600-650℃, the hot air will be into dryer by induce draft fan then drying wet material, evaporation water,after three layer heat transfer, when the wind temperature reduce to 55-60℃ will discharge from dryer.Dust which content moisture after cyclone dust collector , Wet dust collector purification reached the standard then discharge.
