As the powder materials industry moves toward greater precision and efficiency, the performance of processing equipment directly determines the ultimate value of the materials. From non-metallic mineral fillers to new-energy battery materials, from nano-electronic powders to graphite electrode raw materials, the requirements for powder particle size, dispersibility, surface activity, and purity are becoming increasingly stringent. As a core piece of equipment for advanced powder processing that integrates multiple functions, the Honeycomb Mill—thanks to its innovative “first deagglomeration followed by drying, with simultaneous surface treatment” process—breaks the limitations of traditional multi-equipment serial processing and provides highly efficient solutions for powder material processing across various industries.

The breakthrough advantage of the honeycomb mill stems from its precise control over the entire powder-processing workflow. By employing a three-stage core process, it simultaneously achieves drying, depolymerization, and modification—all without the need for additional equipment connections—thereby reducing energy consumption and material loss right from the source.

The deep-drying stage, serving as the foundation of the processing, precisely introduces hot air and materials into the drying chamber. Driven by a high-speed rotating rotor, this process creates a turbulent flow state, and with the aid of vacuum flash evaporation technology, moisture is rapidly removed from the materials. The equipment can withstand up to— With a hot air input at 450℃, the outlet temperature is precisely controlled to maintain stable product dryness, ultimately reducing the moisture content of the powder to below 5‰. This process completely breaks the hydrogen bonds on the surface of nanoparticles and eliminates adsorbed moisture bridges, thereby removing any obstacles for subsequent depolymerization processing. This drying method features a large heat exchange area and achieves a 30%–50% improvement in thermal energy utilization compared to conventional equipment, making it particularly well-suited for drying wet-milled filter cakes and slurries.

The disaggregation and dispersion stage is crucial for ensuring the uniformity of powder particle size. The equipment is equipped with multi-stage, vertically mounted disaggregation wheels, each consisting of hundreds of blades, to... Operating at a high linear velocity of 110–160 meters per second, the rotor interacts with the stator’s specially designed groove structure to create 160 turbulent “honeycomb” zones. Within this region, shear forces, frictional forces, and centrifugal forces work synergistically to rapidly break apart and disperse agglomerated powders, precisely restoring them to their original particle size or natural crystal form while avoiding the particle-size non-uniformity caused by excessive grinding. For powders that have been ultrafine-milled and thus exhibit sharp-edged particles, the mutual grinding between particles themselves and between particles and equipment walls can further shape the particles, significantly reducing their aspect ratio.

The compounding and modification step imparts enhanced functionality to the powder. While the powder is in a boiling state, After being atomized, 1–3 types of modifiers are precisely sprayed and thoroughly mixed with the powder in a turbulent environment, forming a uniform single-layer nano-coating within just 3 seconds. The coating coverage rate reaches as high as 99.2%, and the activation rate is as high as 99.8%. The utilization rate of the modifiers is significantly enhanced after atomization by compressed air. Combined with a negative-pressure air-sweeping system, this process enables continuous production with zero dust leakage, ensuring both a safe operating environment and preventing waste of the modifiers.
