Drum Dryer

Drum dryers, including single drum dryers, have strong material adaptability and are widely used in various industries, offering advantages like simple operation, dust prevention, sealing, and maintenance, and can be configured as standalone units or complete systems.

• Capacity: 20-400 t/d
• Dried Moisture(%): 12-15% (Adjustable)
• Heat Source:biomass, steam, natural gas, diesel, etc.
• Application:Widely used for drying organic fertilizer, compound fertilizer, dregs and other powder, small particle, non sticking property and weak bond material.

What is Drum Dryer?

Drum Dryer or Single Drum Dryer is of strong adaptability to kind of materials. This equipment is the most commonly used drying equipment in cement plant for drying limestone, clay, coal powder and mixed materials and widely used in metallurgy, mining, electricity, chemical industry, and other sectors. As key equipment, drum dryer is known for its advantages such as simple and reliable operation, excellent dust prevention, good sealing effect, and convenient maintenance. Besides, this equipment can be set up as an independent unit as well as a complete system which is including dust collector, feeder, conveyor and other necessary machines.

Applications of Single Drum Dryer

>>Slag, clay, bentonite, limestone, sand, silica sand, quartz sand, kaolin, etc. in building material industry;

>>Ore, metal powder, diatomite, Coal slime, coal, mixed fine coal, etc. in coal industry, chemical industry, mining, metallurgy and other industries;

>>Organic compound fertilizer, sludge, organic fertilizer, inorganic fertilizer, etc. in the fertilizer industry;

>>Other moist powder and granular materials of special requirements like all kinds of crystal, light calcium carbonate, active white earth, magnetic powder, graphite, inorganic mud, argil, lime slurry, mineral mud, phosphorus slag, red mud in aluminum plant, etc.

Structure and Advantageous Functions of the Drum Dryer

With the working principle of heat transfer and effect of the gravity, Drum Dryer is mainly composite with the drum, the lifting plate, the dryer roller, and the feeding box. The drum is set at a certain angle of the processing of the materials. The plates lift the wet powder or particles up and down so that the heat transfer is accomplished. The roller is the force for the drum to whirl around in order that the materials can get enough the heat of the inner wall. ZonedingDrum Dryer is of the following advantages:

• Adapt to a variety of materials drying operation, can reasonably adjust machine parameters depending on different material humidity and nature, more targeted and higher drying quality.
• Concurrent drying, heating medium and wet materials high temperature in and low temperature out; highly efficient and reasonable.
• High-temperature resistance, fast drying, less fuel consumption, and low drying cost.
• After drying, the moisture content of coal slime is lower than 8% and the granularity under 8mm.

Difference Between Single Drum Dryer and Three Drum Dryer

	Single Drum Dryer	Three Drum Dryer
Diameter of Outer Cylinder(m)	1.2-3.6	2.5-3.6
Length(m)	8.0-28.0	7.0-8.0
Volume(m³)	9.0-285.0	16.63-81.38
Capacity(T/H)	1.9-76.0	Yellow Sand:25-70 Slag: 20-65

There are types of drum dryer like single drum dryer, double drum one, three-drum one, and air-flow dryer, etc. Two of mostly used drying machines are compared here. Hope it arises a little help. From this table, it is clear that:

1> Three Drum Dryer takes less space but a better utilization of the heat;

2> Three Drum Dryer is of lower energy consumption than a single drum dryer when they take the same space; 

3> Single Drum Dryer is of larger capacity and lower price;

4> Single Drum Dryer is easier operated and maintained. 

Attention Needed When Operating a Single Cylinder Dryer

• Pay attention to the burning system, sir-blower fan, and the dust collector, because the efficiency of the machine mainly depends on the operation of the burning system;
• Light the oven 1 hour before the work of the dryer and give a careful check to all the attached equipment;
• Turn on the Drum Dryer Equipment in this order: the motor, the wet materials conveyor and the dry materials conveyor, which is a constant and even process;
• Control the temperature of each bearing under 50℃ when the dryer is working. Besides, keep the wheels, the cylinder and other rolling parts rotate stably and normally.
