Rewetting Agglomerators

Rewetting Agglomerators

Rewetting Agglomerators are used in fine sized powders (or powder mixes) that require agglomeration in order to become instant, free-flowing and dust-less consumer products (with fixed micro-composition).

Rewet agglomeration involves dispersion of the fine powder in air, rewetting it by mixing it with small droplets of liquid to form loose agglomerates with point-to-point contact. The material handling during the agglomeration process itself is specially controlled according to the desired properties of the end-product.

The agglomerates are dried, cooled and screened. Fines and milled oversize material are recycled.

Common Processes

• Wetting of the surface of the particles
• Agglomeration
• Redrying
• Cooling
• Sizing
