1. Classification by material form

Paste-like material

Characteristics: High viscosity, poor fluidity, and prone to adhering to the inner walls of equipment.

Applicability: The disc dryer, through the forced stirring and layer-by-layer turning by the rake blades, can effectively break up paste-like material clumps and promote heat exchange.

case

Chemical industry: drying dye intermediates, rubber auxiliaries, electroplating sludge, etc.

In the field of environmental protection: treating printing and dyeing sludge and paper-making sludge, reducing the moisture content from 80% to below 30%.

Granular material

Characteristics: Wide particle size distribution, requiring avoidance of particle breakage or agglomeration during the drying process.

Applicability: The rake blade speed is adjustable (3-15rpm), with gentle stirring to reduce particle wear, suitable for fine chemical products.

case

Pharmaceutical industry: dry granular antibiotics, vitamins, and traditional Chinese medicine extracts.

Food industry: dried starch, glucose, salt crystals.

Powdery material

Characteristics: prone to flying, requiring enclosed operation to prevent dust pollution.
