Feed and Discharge System
Metered infeed and stable discharge are primary drivers of output consistency. Typical layouts include vibratory dosing, guided chamber flow, and pneumatic transfer to separation and collection.
Mécanisme d'alimentation efficace
Le matériau destiné à la pulvérisation est introduit en douceur sur un disque pulvérisateur rotatif fixe à grande vitesse via un alimentateur vibrant contrôlé avec précision, garantissant un flux de matériau constant.
Force centrifuge dynamique
Un disque intérieur intégré exploite la force centrifuge pour guider de manière experte le matériau à travers le disque pulvérisateur, le propulsant dans une chambre externe pour une décharge efficace.

System Configuration
A fine grinding installation is typically delivered as a system. Define upstream feed preparation, separation and collection, and optional size classification to match your target mesh and throughput.
| Module | Fonction | When Needed | Notes / Interfaces |
|---|---|---|---|
| Granule dosing (vibratory feeder) | Stable mass flow into the mill | Recommended for consistent output | Match feed rate to disc loading and target mesh |
| Metal separation (magnet) | Protects discs and chamber | Recommended when feed contamination risk exists | Install before dosing for best protection |
| Air conveying line | Powder transport and heat removal | Typical for powder transfer to separation | Airflow is tied to fan power and duct routing |
| Cyclone dust separator | Primary powder separation | Available for dust removal and product collection | Typically paired with final filtration for fines capture |
| Dust collector (bag filter) | Final fines capture | Typically required for clean discharge | Confirm site dust handling and disposal method |
| Water cooling (optional) | Removes process heat from the grinding zone | When heat-sensitive resins or fine mesh targets increase temperature | Confirm water supply or closed-loop cooling, and connection requirements on quotation |
| Screening / classification (optional) | Narrower size distribution | When tight oversize control is required | Can be paired with return loop for oversize recycle |
| Oversize return loop (optional) | Reprocesses oversize fraction | When classification is installed | Improves yield at tighter mesh targets |
| Sound enclosure (optional) | Noise reduction | When installed near operators | Confirm access panels for maintenance |
Throughput Performance
Throughput depends on model size, disc configuration, target mesh, and polymer behavior under shear. Use the specification table for shortlisting, then confirm capacity against your resin, feed temperature, and required powder fineness.
Rendement élevé
Continuous-duty design supports steady production when feed rate, disc gap, and airflow are matched.
Material-Dependent Capacity
Hardness, brittleness, and impact behavior affect disc loading and the achievable kg/h at a given mesh.
Mesh Target Tradeoff
Finer powder targets generally reduce throughput and increase heat generation. Define acceptable size distribution before final sizing.
Thermal Management
Disc milling generates heat that can affect resin properties and powder flowability. Temperature control and internal cooling help stabilize the grinding zone and reduce thermal spikes during continuous operation.
Contrôle automatique de la température
Stabilizes the grinding zone temperature to support repeatable operation across different resin batches.
Optional Water Cooling
Water cooling can be configured to remove process heat, reduce melt risk, and maintain stable powder discharge.
Process Stability
Stable temperature supports consistent gap setting behavior and helps reduce variability in size distribution.
Maintenance and Wear Parts
Uptime is driven by disc wear, access for adjustment, and cleaning time between resin changes. Evaluate wear-part intervals and service procedure against abrasiveness, contamination risk, and shift schedule.
Disc Wear Life
Disc design targets long service intervals to reduce resharpening frequency and planned downtime.
Adjustment and Replacement
Disc gap adjustment and disc replacement are designed to be performed quickly to restore output consistency.
Cleaning Access
Access design affects changeover time when switching polymers, colors, or additive packages.
Operating Cost Drivers
Cost per kilogram is driven by energy input, wear parts, and operator time. Confirm utilities, consumables, and maintenance intervals during quotation to estimate unit economics for your mesh target.
Energy per Kilogram
kWh/kg varies with resin type, fineness target, and airflow settings. Finer mesh targets typically increase energy input.
Wear Parts
Disc service interval and resharpening/replacement plan are primary consumable drivers for long-run operations.
Labor and Changeover
Feeding, monitoring, and cleaning time affect labor cost. Faster access can reduce changeover losses between runs.

Polymer Compatibility
Input resin brittleness, hardness, and impact behavior affect achievable mesh and stable disc loading. Confirm resin type and feed condition before final model selection.
Suitable Resin Types
Medium-hard, brittle, or high-impact resins including PE, PVC, and PC granules.
Feed Form and Size
Granular feed is recommended. Maximum feed size is 14 mm for stable metering and disc loading.
Particle Size Control
Final size distribution is determined by disc tooth geometry, operating gap, and material response to shear. Define target mesh and allowable oversize when specifying the system.
Typical Size Range
20 to 100 mesh, depending on disc configuration and operating settings.
Optional Screening
Screening can be integrated when tighter control of oversize or a narrower cut is required.
Warranty and Service Terms
Warranty scope, exclusions, and service response are defined in the quotation and sales contract. Align coverage expectations with operating hours and maintenance plan.
Standard Warranty
Standard warranty term is 12 months.
Technical Support
Lifetime technical support is offered. On-site support and extended coverage depend on the selected service package.
Installation and Utilities
Define site utilities and layout constraints early to avoid capacity losses from poor duct routing, insufficient cooling, or restricted service access. Final requirements are confirmed on quotation.
