Rotary drum dryer is a kind of direct heating method. This direct
heating method is of high efficiency and low lost.
A rotary dryer is suitable to dry metallic and nonmetallic mineral,
clay in cement industrial and coal slime in coal mine, etc. Rotary
dryers can be widely used to dry various materials,
most commonly seen in the mineral industry for drying sands,
limestone, stones and soil, ores, fertilizers, wood chips, coal,
iron sulphate, filter cakes, sewage sludge, other sludge, etc.
The technical solutions are as varied as the materials. Depending
on the raw material, application and water content involved, we
design and manufacture the right rotary dryer system for customers.
In addition to a precisely controlled drying process, another
important factor for drying biomass is a facility's
cost-effectiveness - making use of free waste heat.
Working principle of roller scraper dryer
Drying process: Let the liquid or muddy material form a film on the
surface of the drum heated by steam or other heat carriers. The
drum is dried in one revolution. The product is scraped off with a
scraper, and the exposed surface of the drum comes into contact
with the raw material again. And form a film to dry.
The drum scraper dryer uses a certain method to spread the liquid
or pasty material on the drum (hollow metal cylinder) with a
0.1-1.5mm film. The drum can be heated with steam, hot water or
thermal oil. When the drum rotates once, the material can be dried
and scraped off the surface of the cylinder by a special scraper.
The drum scraper dryer generally rotates at a speed of 4 to 6 rpm.
The drying of the paste-like material is to adjust the thickness of
the material and to compact the material layer. On the side close
to the feeding device, a material compression shaft is installed to
make the material evenly spread on the drum. In order to make the
material easier to fall off when the scraper discharges the
material, before the scraping, the cold air pipe can also be used
to blow a certain amount of cold air to cool the material.

Features of drum scraper dryer
1. Large operation flexibility and wide adaptability, the operation
flexibility of the drum dryer is very large, and can adapt to the
requirements of multiple materials and different output;
2. The thermal efficiency of the roller scraper drying is high;
3. The drying time is short, the wet material film of the material
to be dried on the outer wall of the drum is generally 0.3 to 1.5
mm, and the entire drying cycle takes only 10 to 60 s;
4. Large drying rate: Because the material film is very thin, the
surface of the material film can maintain the drying strength of
15-50kg water/m2h;
5. Continuous operation, stable quality, labor saving, and uniform
product can be obtained;
6. The inside of the machine is easy to clean, and it is easy to
change the variety;
7. Exhaust gas does not take away materials, and no dust removal
equipment is required.
