High-output Fertilizer Rotary Drum Dryer Introduction
Rotary drum drying machine, which consists of rotary body, lifting plate, driving device, supporting device and sealing ring, is an ideal drying equipment for fertilizer industry, both compound fertilizer production and organic fertilizer production. It is used to reduce the moisture content of fertilizers. After drying, the moisture content of compound fertilizer will be reduced from 20%-30% to 2%-5% and the moisture content reducing range of organic fertilizer is from 10%-40%.

gear transmission of rotary drum dryer

It has advantages of low noise, fast delivery, reasonable design, high efficiency, low energy consumption and easy to operate. This rotary drum dryer can be widely used in different fields, such as bio-mass pellet industry, feed pellet industry, building materials drying, animal manure drying and so on.

High-output Fertilizer Rotary Dryer Feature

1. High operation flexibility. Rotary drum dryer operation is very flexible. Changing one of the many factors that affect drum drying, such as drum speed, material properties, will not influence the drying operation.
2. Reasonable design. The rotary drum drying machine has reasonable design, the angle of the body and the distribution of lifting plate which helps to improve the heating efficiency.
3. High thermal efficiency. The hot air passes through the rotary body with some resistance and mix with materials completely and dry evenly.
4. Convenient maintenance and use, low repair cost, continuous and reliable operation, large capacity.
5. Wide application range. This rotary drum drying machine is multi-functional and can be used for drying different materials.
6. Fully automatic control, strong overloading capacity resistance.

rotary drum dryer working principle

Working Principle of High Output Fertilizer Drying Machine
This fertilizer rotary drum drying equipment uses hot air to dry the materials. From the high side as the rotary drum dryer has an angle, the wet materials are entered into the hopper of the rotary drum dryer by belt conveyor or bucket elevator. In the rotary body, the materials are mixed with hot air which enters into the rotary body from the lower side. The materials are lifted by the lifting plate on the inner side to make the materials and the hot air mix completely which improve the drying efficiency. while the fertilizer drying machine rotating, the well-dried materials are collected from the other side. According to the need, the hot air can enter the rotary drum drying machine from the feeding side or discharging side.

Application of Fertilizer Rotary Dryer
rotary dryers are among the most versatile available for drying fertilizer, and are capable of handling almost any bulk solid material regardless of its conveyance and handling characteristics.
1. Suitable for organic fertilizer & compound fertilizer: organic & compound fertilizer granules, livestock manure waste, poultry manure, such like sheep manure, pig manure, chicken manure, caw manure etc. and compost, sludge.
2. Suitable for bio-mass pellet industry: wood sawdust, wood chips, wood shavings, agricultural straw
3. Suitable for feed and agriculture industries: straw, grass fish meal, leaves, food factory waste, corn sauce
4. Suitable for building materials drying, metallurgy and chemical industry, mining industries: respectively, sand, cement, ores, slag, coal, metal power, clay, kaolin
5. Suitable for drying powder and granular materials: phosphorus slag, crystals
