Powder Processing

Fluidized Bed Powder Processing Systems

SCHWING Technologies provides solutions for fine particle treatment with our Fluidized Bed Reactors (FBR). Our systems are appropriate for a wide range of applications, where process atmosphere and temperature uniformity are crucial to producing materials of consistent quality. SCHWING FBRs provide excellent heat transfer and maximum gas-solid contact to facilitate numerous thermochemical reactions. Around the world, our customers appreciate the simplicity, reliability, and low maintenance of the fluidized bed system. SCHWING’s pilot plant is highly flexible for process development—providing feasibility and optimization trials.

Controlled Atmospheres for Gas-Solids Reactions
