Coal-based wet slurry is a core intermediate feedstock in coal chemical processing. Fine coal particles tend to form tightly packed agglomerates, leading to insufficient reaction completeness upon feeding into the reactor and fluctuating raw material utilization rates, while also increasing the burden on flue-gas treatment. Conventional grinding relies on relatively weak shear forces, capable only of breaking down large chunks of material but struggling to disintegrate micron‑scale agglomerates.

The ultrafine powder cell mill employs a multi‑stage turbine shear design to progressively break down coal‑powder agglomerates, ensuring uniform dispersion of slurry particles and enhancing gasification reaction efficiency. Its vertical chamber is equipped with a water‑circulation temperature‑control system, preventing slurry heating and caking during prolonged processing and ensuring stable short‑term storage.

The equipment features a modular, hierarchical design that allows for the addition or removal of grinding stages, accommodating both laboratory-scale trials and large‑scale production at the ten‑thousand‑ton level. It is suitable for preparing coal‑to‑ammonia and coal‑to‑methanol slurries, with automatic fineness control and compatibility with various coal feedstocks across a wide range of moisture contents, offering strong versatility.
