New Designed High Quality Organic and Compound Fertilizers Rotary Drum Dryer 

D.R.M. Organic and Compound Fertilizers Rotary Drum Dryer    

We've built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your materials. Whether you require low or high inlet temperatures,short or long residence times, counter current or co-current flow, D.R.M.'s design team can design a rotary dryer for your application. 

Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.

Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. 

The drum is positioned at a slight horizontal slope 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. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.

Direct Rotary Dryer Applications & Materials

Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a habd in nearly any industry requiring drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:

Aggregates         Gypsum         Municipal Waste & Sludge       Rubber Pellets        Agricultural By-Products   Inorganic Chemicals                 Salts & Sugars                          Animal Feeds          Limestone                           Paper Sludge       Sand              Biomass              Manure         Plastic Pellets & Grains                                     Steel Mill Waste Sludges         Biosolids             Metal Chips & Shavings               Potash                                 Urea Prills & Crystals               Fertilizers            Mining Ores & Concentrates       Reclaimed Dust

Unlike direct dryers, indirect dryers do not reply on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material. 

While indirect dryers are less efficient compared to their direct counterparts,they offer some advantages that can make them an attractive alternative. This includes: 

- Less exhaust air treatment

- No risk of entrainment of fine materials

- Precise temperature control along the length of the dryer can be achieved
