Rotary Dryer


In organic fertilizer production, material needs to be dried to remove water from solid organic fertilizers. Rotary dryers, strong equipment with proven technology and a long service life.


rotary dryerRotary dryer, consisted of drum, lifting board, transmission device and support device and other assembly parts, can be custom designed to suit the unique processing needs of customers’ material. The drum should be fixed at a slight horizontal slope (about 2-5 degree) to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. In virtue of simple operation, low energy consumption, long lifespan, even drying and easy maintenance, our rotary dryer has been widely applied into agriculture, feed and fertilizer industry, such as straw, pasture, organic mixed fertilizer, fish meal, starch residue, organic fertilizer, waste of aquatic products, especially used to dry fertilizer with certain temperature and particle size in organic fertilizer production.

We provide Eco drying solution with exhaust air control to meet your needs to have clean exhaust and smell free.

Working Principle of Rotary Drum Organic Fertilizer Drying Machine:

Rotary drum dryer runs on the principle that belt and belt pulley, driven by main motor, transmit to driving shaft through reduction gears, and then split gears installed on driving shaft can engage with big gear ring fixed on engine body, working in the opposite direction. Materials are added from feed end, then enter into drum under the attractive force of hot-blast air generated by hot blast heater and draught fan. During this process, the lifting board installed in drum would turn over materials continually so as for even drying, and materials would outflow from discharge hole after drying. after being dried by rotary dryer, the temperature of fertilizer granules/prills can reach 60-80℃. Then the hot organic fertilizers are transported to rotary cooler for further processing.

Advantages of Rotary Dryer:

  1. With low investment and good economic returns, our rotary dryer has stable running performance, high reliability and strong anti-overloading capacity.
  2. Without discharge of three waste, this machine is stable to operate and convenient to maintain. Moreover, it has the advanced technology, large handling capacity, limited fuel consumption and low drying cost.
  3. The lifting board of rotary dryer has reasonable layout and angle design, reliable performance and appearance so as for high heat utilization ratio, even drying and obvious energy-saving effect.
  4. With superior quality anti-corrosion and wear-resistant materials, this rotary dryer has impact structure, longer lifespan and higher running efficiency.
  5. Rotary drum dryers are equipment for the treatment of numerous products, such as chemical products, fertilizers, minerals, solid waste materials, vegetables and fruits and a large range of granulated fertilizer or pulverized solid products. They are suitable for drying a wide range of materials because of their ability to process materials having considerable variation in size and composition.
