Rotary Heating Dryer Machine for Drying Coal Slime, Slurry, Mud

Introduction:

Rotary dryer is a kind of highly efficient, stable and reliable heating drying equipment, and its performance is better than tube bundle rotary dryer, blade rotary dryer. Drying machine adopts "center - adjusting roller device", making the cooperation of roller and rolling ring always show linear contact which greatly reduces the wear and power consumption. This machinery is applied in the materials like coal slurry, mud, felted gypsum, Muddy, high - moisture swell soil, electroplate mud and so on.

Features:
1. Mass processing
The number of heating tubes is large and the heat transfer area per unit volume is the largest of all the rotary dryers presently available
2. Easy operation
Large changes in processing quantity can be fully absorbed, featuring ample retention time and simple adjustments, only temperature of heat source needs to be controlled for drying operation
3. Energy-saving
Thermal efficiency is extremely high especially for processing a large quantity of
material at low temperature, mechanistically, the driving power is smaller and also
running costs are lower
4. Low leakage
The special gas sealing mechanism seals the dryer to prevent both inert gas from
leaking and air from flowing into the dryer, therefore, solvent is recovered easily and inert gas emissions are lower
5. Low pollution
Indirect heating minimizes inert gas emissions, inert gas treatment system and
deodorization system can be made compact


 

Application And Operating Principle:

The moist material enters the dryer from one end. With the stirring of the uniformly distributed lifting blade inside the shell, the material disperses equably inside the dryer. In this way, the material is fully exposure in the flowing hot - air, and the drying process is quickened. During the drying process, the material is moved manageably to the other end of the dryer under the effect of both the gradient and the hot - air. Thus the finished product is produced.

The rotary dryer is mainly applied in the drying of the material, which requires for low - temperature drying and mass continuous drying, for example, the drying of large particles and large specific gravity, such as the ore, coal, metal power, blast - furnace slag,phosphate fertilizer, thiamine, and so on, in the industries of chemical, mineral, metallurgy and etc; and the drying of powdery and granular material of special requirements, such as the HP foaming agent, vinasse slag, light calcium carbonate, activated clay, magnetic powder, graphite, herb residue, and etc.
