Sludge Rotary Dryer Equipment

Drying equipment is widely used in industrial production To accommodate materials of different shapes and properties, currently widely used drying equipment includes: box dryers, vacuum belt dryers, spray dryers, air flow dryers, fluidized bed dryers, rotary dryers, and paddle dryers. In the field of sewage treatment, paddle dryer machines are widely popular due to their unique features.
1. The shaft, blades, and casing can all conduct heat, offering a large drying area and fast drying speed. The thermal efficiency is over twice that of ordinary drying equipment, reaching over 80% efficiency.
2. Various operation methods are available, including intermittent or continuous operation, pressure or vacuum operation, and suitable for heat-sensitive materials.

3. The axis speed is adjustable (usually 3-25 r/min, outer speed 0.03-1.5m/s), allowing control of the drying temperature, drying time, final moisture content, and production. The material is evenly mixed and dried
4. Since it uses conduction heating, it requires less gas for drying, significantly saving energy. Compared to similar products, it saves about 40% of steam and 30% of electricity.
5. There is very little dust carried, and the emitted gas is easy to handle. Subsequent processing equipment such as dust capture systems and material steam recovery systems have low loads or can be omitted.
6. The blade structure is special, and its heating surface has a self-cleaning function.
7. When using inert gas as a carrier, organic solvents can be recovered.
8. Dual-axis low-speed rotation, minimal wear on blades and shaft.
9. Few fragile parts, low operation and maintenance costs, only the bearing and the internal stationary ring of the rotary joint are fragile parts.
The hollow blade dryer is a new energy-saving dryer, widely welcomed in the context of energy efficiency and environmental protection due to its energy efficiency and good operating environment. Its application will become increasingly widespread.
