Automated Multi-Component Feeding and Pneumatic Conveying System for Friction Materials High-Precision Automatic Dosing, Mixing, and Conveying System for Friction Material Extrusion Lines

1. Intelligent Material Identification & Handling

• Auto-Recognition System: Materials are placed on pallets and scanned via a Material Identification System before entering the hoist. This ensures the right material reaches the designated silo every time.

• Hydraulic Tilting Unloader: Features an Automatic Hydraulic Tilting Station with integrated dust collection. The system uses pneumatic cylinders to lock the material frame, preventing any leakage during discharge.

• Hoisting & Distribution: High-efficiency hoists and shuttle cars automatically transport raw material pallets to the specified feeding positions on the steel platform.

2. Specialized Dosing for Complex Ingredients

• Fiber-Optimized Feeding: Specifically designed to handle Metallic Fibers and other fibrous materials that are prone to bridging. The system utilizes pneumatic vibrators and anti-arching devices to maintain a steady flow.

• Precision Weighing Logic: Employs a Circulating Roller & Lifting Scale design. This multi-stage weighing approach is more efficient than traditional shuttle cars, making it ideal for high-volume, multi-batch production.

• Manual Error-Proofing: For small-dose additives, the system includes a Barcode-Verified Manual Dosing Station. Feeding ports only unlock after a successful scan, with a touch-screen display guiding the operator through the process.

3. Advanced Mixing & Process Control

• Multi-Stage Mixing Interface: The system controls a complex sequence involving Kneaders (Internal Mixers) and High-Speed Mixers. It manages specific durations for plasticization (3-6 min), dry mixing, and final blending (10-20 min).

• Liquid Resin Integration: Supports the precise injection of Liquid Resins into the mixing chamber at the exact phase of the production cycle.

• Automated Cleaning: Features centralized dust removal and a "heavy hammer" cleaning mechanism to prevent cross-contamination between different formula batches.

4. System Reliability & Safety

• Dust-Free Environment: All connection points—from bag dumping to mixer feeding—are equipped with negative-pressure dust extraction to meet strict HSE (Health, Safety, and Environment) standards.

• Modular Steel Platform: The entire system is built on a custom-engineered steel structure, optimizing workshop space while providing easy access for maintenance.
