Cow dung can be used as a lot of animal feed, cow dung which contains minerals and a variety of nutrients, including organic matter, total nitrogen, crude protein and other nutrients.
With cow dung as raw materials to produce organic fertilizer, the cost is small, the quality is relatively stable, the market sales space is very big.

Rotary drum dryer is designed to dry Cow dung which contains high moisture.Heat is generate by hot air generator by Coal, gas, petrol,diesel, biomass fuel etc.Total system is automated & moisture in material is adjustable as per requirement in various sectors.Depending on raw material,moisture and required production we can suggest suitable model and an approximate cost of your system in a short time frame.

Working principle

The hot air and wet Cow dung were sent into the main drying unit. Then the wet Cow dung and hot air will be sent into first stage of drying equipment,There is a special broken device in the first stage drying equipment. In this broken device, the wet Cow dung will be broken into scattered and "boiling suspended" state. With the hot air, the scattered Cow dung will be keeping rolling, rotation and separation.  So the wet and sticky and blocking phenomenon of Cow dung is solved. Thus the important transformation "high humid —→ not humid, high sticky —→ not sticky, high viscous to not viscous" is completed.

Water vapor produced in first stage drying process is automatically discharged at the end of first dryer. The scattered Cow dung are discharged into second dryer.The second dryer adopts reverse flowing and vortex drying technique, the drying efficiency is also intensified. At the same time, heat and mass transfer is strengthened, which leads to bound water extravasation and evaporation speed up. Water vapor is discharged at the end of the second dryer. Cow dung are automatically sent into the third dryer . The third dryer adopts interflow plus reciprocating drying technique,the wet Cow dung move slowly and reciprocating, while the dried ones move in advance and fast. Cow dung will be discharged automatically when they are dry enough as request.

Advantages

Special technology can take more energy-saving and efficient for you,and the main structure is consists of three different metal steel cylinder with different diameter, it can get a bigger evaporation area, and drying faster,letting the material make a full contact with the hot air;"Auto-Feeding Control device" can be regulated according to the moisture content of the material;"Negative pressure"working condition, clean work site and operating reliably.
