Analysis of DF Production Technology: A Systematic Process from Milling to Drying

Breakthrough Proprietary Craftsmanship: Synergistic Advantages of High-Flow Disc Bead Mill & Spray Granulation Dryer for DF Industrialization

1. High-Efficiency Milling to Guarantee Superior Slurry Quality

   The high-flow disc bead mill adopts double mechanical end-face seals, polyurethane liners and high-density zirconia grinding media, paired with an optimized rotor structural design. It delivers continuous grinding capacity of several tons per hour with low energy consumption. Its unique cooling system maintains stable temperature during long-hour operation to prevent thermal decomposition of heat-sensitive technical materials. Post-grinding slurry achieves a D90 particle size of 1–10 μm, providing high-stability, low-viscosity feedstock ideal for subsequent spray drying.
2. Precision Drying for One-Step Pellet Forming

   The matched DF-specific spray granulation dryer employs pressure atomization combined with co-current/mixed-flow drying modes, equipped with adjustable hot air distributors and multi-stage cyclone separation systems to ensure uniform heating and controllable residence time of pellets inside the drying tower. The finished DF pellets are nearly spherical with excellent flowability, moisture content below 0.5% and rapid disintegration performance, fully complying with technical specifications for DF formulations.
3. Automated Integration to Improve Overall System Efficiency

   The entire production line realizes interlinked operation via the central control system. All procedures including feed metering, grinding parameter adjustment, drying temperature curve setting and finished product packaging are monitored digitally throughout the workflow. Built-in online detectors feed back real-time slurry particle size variations to dynamically adjust the rotational speed of the bead mill; high-precision temperature sensors conduct non-contact drying inspection to guarantee consistent finished product quality. Notably, the embedded one-touch CIP cleaning system carries out programmed flushing for grinding chambers, conveying pipelines and nozzle assemblies, effectively eliminating cross-contamination between batches and greatly enhancing flexibility and safety for multi-product switching.
