Drum dryer is mostly used in the mining industry and suitable for drying the metallic ores and non-metallic ores including the magnetic concentrate, gravity concentrate, and flotation concentrate. Drum dryer is also applicable to dry the clay of the cement industry and the coal slime of the coal-mining industry. Everything is not perfect, so is the drum dryer machine. Not only does the drum dryer machine have eye-catching advantages but also has some disadvantages. And what aspects is it embodied in? The advantages and disadvantages of drum dryer are summarized as follows:

Advantages of drum dryer:

a. The drum dryer machine with the new type multi-modular material lifter can overcome the wind tunnel phenomenon of traditional dryers. So, drum dryer has high thermal efficiency and its coal consumption is reduced by about 20%.

b. Drum dryer has higher operational flexibility. In the production of drum dryer, it allows the yield of finished product to have a little great fluctuation without affecting the quality of finished product.

c. Drum dryer machine can cooperate with multiple combustion furnaces, such as the high-temperature gas furnace, pulverized coal injection furnace, and manual coal furnace.

d. Drum dryer machine can be equipped with centralized control system, so that large enterprises can realize the central monitoring and management to the drum dryer machine.

e. Drum dryer can carry out continuous producing operation, so the production capacity of drum dryer can reach 2.2~18.5 t/h.

f. Drum dryer has simple structure mainly including the heating device, feeding device, roller device, drying drum, gearing wheel device, discharging device, etc. Drum dryers can be operated conveniently and easy to be repaired when failure occurs.

g. Generally, we can use the drum dryer machine to dry the granular material. At the same time, drum dryer also has great drying effect on the material with large adhesion.

h. The conventional cast steel gears are replaced by the high wear-resistance and high-strength toughness wheel gears. It can help users to save the investment cost and reduce the maintenance costs and time of drum dryer.

Disadvantages of drum dryer:

a. The drum dryer machine is bulky, so it is difficult for users to install and dismantle.

b. It needs a large amount of capital for users to invest in the drum dryer.

c. Some users want to have a large yield of drum dryer, so they may choose a drum dryer machine with too long and too wide drum body. As the result, the drum dryer needs larger footprint. What’s worse, if the space of the drum dryer can’t be fully used, the drum dryer machine inner will have much heat loss and lots of resources will be wasted.

d. The residence time of material in drum dryer is long and the residence time of the material granules is very different, so drum dryer is not suitable for drying the materials that have strict requirements on temperature.
