Turbo Flash Disintegration & Drying Machine

This all-in-one drying & disintegration equipment acts as the front-end material conditioning core for full kaolin processing lines. It integrates hot air dehydration and high-speed turbine impact crushing into a single unit, instantly breaking wet agglomerated filter cakes and damp mineral lumps while removing free surface moisture. It outputs loose, uniform low-moisture feedstock for downstream grinding, maintaining optimal grinding activity and high fluidization efficiency of raw materials.

One-Step Integrated Drying & Disintegration

Traditional filter cake processing requires separate crushers and independent drying ovens, leading to long process flow and extra equipment investment. This turbo machine completes lump breaking and moisture removal in one single pass after feeding, cutting down supporting auxiliary machines. Its circulating impact structure repeatedly crushes stubborn hard agglomerates wrapped with impurities, fully exposing iron-titanium contaminants inside mineral clumps to boost the purification effect of subsequent magnetic separation.

Low-Temperature Instant Drying

Materials only stay inside the chamber for several seconds under mild hot air, avoiding long-time high-temperature baking. For uncalcined kaolin, it fully retains natural lamellar crystal shape without whiteness yellowing; for calcined rework materials, it prevents over-sintering and maintains stable absorption oil value.

Anti-Clogging Turbine Impact Structure

High-speed rotating turbine blades continuously shear and disperse incoming viscous mud lumps. The airflow circulates to flush the inner wall, effectively solving the sticking and blockage issue common in ordinary drying equipment, supporting long-term non-stop continuous feeding.

Wide Raw Material Compatibility

It supports three mainstream kaolin feedstocks: high-moisture washed filter cake, slightly damp agglomerated raw ore, and hardened calcined rework lumps. After treatment, all materials turn loose dry powder that meets the feeding standard of ball mills and impact mills.

Adjustable Outlet Moisture

Hot air temperature and turbine speed are independently adjustable, allowing precise control of outlet moisture content. It can flexibly adapt to the optimal feed moisture requirements of different downstream grinding processes, ensuring stable grinding efficiency and consistent product fineness.

Compact Structure, Easy Daily Operation & Maintenance

Integrated design reduces overall equipment footprint. Wearable impact components are modular for quick disassembly and replacement, lowering long-term labor and maintenance costs for mass-production factories.

Application Limit

This machine only serves as front-end pretreatment equipment and cannot achieve ultrafine grinding of kaolin particles. If raw ore needs direct ultrafine refinement without pre-processing, you should select ceramic ball mills or ACM impact mills instead. It cannot handle large bulk ore blocks over 30mm; primary crushing equipment must be equipped for oversized raw ores.

Ceramic Ball Mill & Horizontal Air Classifier Integrated System for Kaolin

This closed-loop production line combines full ceramic ball mill with high-precision Horizontal Air Classifier, a globally standard processing solution for high-purity kaolin. The full-ceramic grinding unit eliminates metal contamination, while the dedicated Horizontal Air Classifier realizes precise particle size cutting via closed-circuit circulation. The system covers D97 2–10μm particle range, with 5–10μm industrial filler grade featuring maximum throughput and stable continuous operation, perfectly matching coating, paper, rubber and plastic kaolin manufacturing requirements.

Full-Ceramic Anti-Contamination Design

All material contact parts adopt high-purity ceramic, eliminating iron wear pollution from steel equipment. Iron and titanium impurities damage kaolin whiteness and dispersion, failing high-end filler standards. Our ceramic structure avoids secondary metal pollution during grinding, cooperating with front magnetic separation to stabilize impurities at ppm level, sustaining long-term consistent high whiteness and powder purity.

Gentle Tumbling Grinding

Low-stress grinding fully preserves the natural lamellar crystal shape of uncalcined kaolin ore and washed cake, delivering superior hiding power, suspension and lubricity in coating & paper filler applications.

Wide Raw Material Compatibility

Compatible with raw kaolin ore, dried filter cake and calcined rework materials. Wet agglomerated materials need JRTM flash drying & disintegration pre-treatment before grinding, with smooth load fluctuation for long-hour continuous production.

Precise PSD Control with Horizontal Air Classifier

Matched with professional Horizontal Air Classifier, coarse particles circulate back for re-grinding. Horizontal structure offers higher cutting precision than vertical classifiers, generating uniform powder with ultra-narrow PSD.

Mature Industrial Configuration

Globally verified mainstream equipment set. Wear part replacement, routine inspection and capacity expansion are simple to control long-term operation cost.

Application Limit

Long-term mass production of D97 <3μm submicron kaolin leads to obvious throughput decline and higher energy consumption. ACM ceramic impact mill or fluidized bed jet mill is more suitable for ultra-fine demands.

Air Classifier Mill (ACM) for Kaolin Ultrafine Processing

Air Classifier Mill integrates high-speed impact grinding and built-in air classification in one unit, the core ultra-fine equipment for dry kaolin lines. High-speed impact discs crush particles through impact, shear and collision; built-in turbine classifier controls fineness precisely. Coarse powder auto-returns for re-grinding, forming closed-circuit one-step ultra-fine processing for narrow PSD kaolin powder.

Integrated Grinding & Classification

Traditional dry lines need separate ball mills and external classifiers with complex piping, causing high investment and energy loss. This ACM integrates grinding and classification in one unit, completing ultra-fine pulverization and size classification in one pass. Coarse particles auto-recycle inside without external conveying, shortening process and cutting energy use. Stepless classifier speed enables flexible fineness switching for coatings, rubber and paper kaolin specifications.

Strong De-agglomeration

High-speed impact discs generate strong collision and shear forces, effectively breaking hard agglomerates in calcined kaolin rework. Restores individual particles more efficiently than ball mills, improving powder dispersibility in downstream polymer systems.

Wide Fineness Range

Adjusting classifier speed and air volume flexibly controls D97 3–45μm fineness. One machine covers general fillers to medium ultra-fine kaolin, reducing extra equipment investment for multi-product factories.

Full Dry Process

Entire grinding and classification runs dry, no water or slurry involved. Finished powder goes directly to packaging or surface modification, eliminating post-drying and moisture control costs, ideal for dry kaolin deep processing lines.

Ceramic Lining Optional

Chamber lining, impact pins and classifier blades can be customized with high-wear ceramic materials, avoiding iron contamination from steel abrasion. Meets high-purity kaolin requirements for coatings, cosmetics and electronic fillers.

Compact & Easy Maintenance

Integrated vertical design saves over 30% floor space vs. separate mill + classifier sets. Side quick-access doors simplify inspection and wear part replacement, minimizing maintenance downtime.

Application Limit

For mass production of low-value bulk kaolin below 800 mesh, ACM brings higher unit procurement and operation cost than ceramic ball mill systems, resulting in poor economic efficiency. This equipment is cost-effective mainly for medium & high-value ultrafine kaolin for coatings, rubber and special filler industries.

Fluidized Bed Opposed Jet Mill for High-Purity Ultrafine Kaolin

Fluidized bed opposed jet mill is flagship ultrafine grinding equipment for high-end kaolin. It relies on high-pressure airflow for particle self-collision crushing without grinding medium contact. Matched with high-precision classifier, it stably produces submicron-level ultra-pure kaolin, fully meeting strict standards of electronic substrates, cosmetics and high-performance composite fillers.

Medium-Free Self-Collision Grinding

Unlike ball mills and impact mills equipped with metal grinding parts, this jet mill crushes materials via particle-to-particle collision. No metal components touch kaolin powder during the whole grinding flow, eliminating iron-titanium impurities generated by steel wear. Even without ceramic lining, metal residue can be controlled to ultra-low ppm level, fully matching ultra-high purity requirements of electronic, medical and cosmetic kaolin and solving core purity pain points of downstream high-end manufacturers.

Stable Submicron Fineness Output

High-pressure opposed airflow delivers uniform ultrafine crushing. Stepless classifier adjustment stably produces kaolin powder with D97 ranging from 2 to 6 μm, far exceeding the stable fineness limit of ball mills and ACM impact mills for high-end filler production.

Gentle Crushing, Less Lamellar Damage

Particle self-collision avoids intense mechanical shear force compared with ACM impact mills. It greatly reduces fragmentation of uncalcined kaolin flakes, retaining excellent hiding power, insulation and suspension performance of raw kaolin.

Closed-Loop Dry One-Step Processing

The whole process runs fully dry with integrated grinding and classification inside the unit. Coarse particles circulate automatically, finished powder directly enters modification or packaging without secondary drying treatment.

Ultra-Narrow & Controllable PSD Curve

Air volume and classifier speed are regulated independently to lock particle size distribution tightly. Ultra-narrow PSD reduces large-particle impurities and stabilizes insulation & heat resistance of electronic composite materials.

Modular Structure, Easy Cleaning & Grade Switching

Detachable fluidized bed and classification chamber simplify full machine cleaning. It effectively avoids cross-contamination when switching batches of cosmetic and electronic high-purity products.

Application Limit

High equipment investment, large gas consumption and low single-machine throughput lead to poor economic efficiency for mass production of conventional D97 ≥5μm industrial fillers. This jet mill is only cost-effective for small & medium batch production of high-value electronic, medical and cosmetic ultra-pure kaolin; mass low-end filler lines should select ball mill or ACM impact mill to cut processing cost.

Three-Roller Vortex Surface Modification Mill for Kaolin

Continuous dry surface modification unit with three groups of staggered rotors to build multi-stage vortex field. Kaolin powder and quantitative modifier go through repeated shear, collision and friction inside three serial chambers. Self-friction heat melts coating agent to achieve uniform surface coating, with built-in de-agglomeration function. It matches ball mill, ACM and jet mill as post-processing equipment for plastic & rubber filler kaolin.

Three-Stage Serial Vortex Coating

Ordinary single-cavity modification machines form static dead zones and cause inconsistent coating effect. This mill adopts three separated mixing chambers and staggered high-speed rotors, materials circulate through multi-stage turbulent flow to avoid local accumulation. Strong vortex shear fully breaks kaolin agglomerates and ensures full contact between each particle and molten modifier. Compatible with stearic acid, titanate and aluminate coupling agents, it delivers stable activation index during mass production, eliminating batch difference of finished filler powder.

Self-Friction Heating, No External Heater

Heat generated by high-speed friction between powder and rotors melts solid modifiers directly. No extra heating furnace or heat preservation pipeline is required, simplifying production layout and cutting auxiliary equipment investment.

Built-In De-Agglomeration

Multi-stage vortex shear crushes hard agglomerates generated after ultrafine grinding. Modified powder keeps good flowability and can be delivered to silo packaging without secondary screening.

Low Operating Cost & Large Throughput

Power consumption is around 30 kWh per ton of powder. Less auxiliary equipment reduces maintenance workload, with max single machine throughput up to 6t/h to satisfy large filler factory demands.

Full Negative Pressure Sealed Operation

Whole system runs under negative pressure with matched cyclone and bag dust collector. Sealed feeding and discharging stop powder leakage, improve workshop environment and cut raw material waste.

Wide Matching Range With Front Grinding Equipment

Independent metering feeding structure can directly connect turbo dryer, ceramic ball mill, ACM and jet mill, realizing integrated grinding & modification process without intermediate buffer silos.

Application Limit

Temperature control accuracy is limited by self-friction heating, so it is not ideal for D97<3μm ultrafine kaolin that requires constant-temperature coupling agent coating. It also has poor economy for small-batch silane modification of high-end products.
