How to Design a Turnkey Solution for Recycled Carbon Black (rCB)

A full turnkey recycled carbon black system converts crude pyrolysis char from waste tires, plastic and biomass into high-purity, uniform ultra-fine rCB (D90 < 10μm) for rubber, plastic and coating industries. Based on JACAN Powder Equipment’s 19 years of rCB processing engineering experience, this article outlines a systematic, modular design framework covering project pre-assessment, core process layout, equipment matching, intelligent control, environmental protection, after-sales delivery and full lifecycle operation support — forming a one-stop, fully integrated turnkey production line solution.

1. Pre-Project Assessment & Customization Design Foundation

Before drafting the turnkey layout, complete targeted project evaluation to avoid mismatched capacity, poor product quality and excessive operation costs.

1.1 Raw Material & Product Index Confirmation

• Feedstock source: Tire pyrolysis char / plastic pyrolysis char / biomass char; test impurity content (steel wires, ash, gravel), moisture, agglomeration degree and hardness
• Target rCB standard: Fineness (D90 < 10μm required for high-end rubber), ash content, volatile matter, particle size distribution width, reinforcement performance
• Production scale: Customize hourly throughput (1–15t/h) according to daily pyrolysis char output, supporting 24/7 continuous operation

1.2 Site, Budget & Compliance Survey

• Factory layout: Plant height, floor load, raw material warehouse, finished product storage, dust emission area, power supply capacity
• Cost positioning: Balance German/Japanese equivalent performance with 1/3 of their procurement cost as JACAN’s core advantage
• Local compliance: Dust emission, noise, fire & ATEX explosion-proof standards for carbon black powder production

1.3 ROI & Maintenance Budget Simulation

Calculate full total cost of ownership (TCO): initial equipment investment, power consumption, annual wear part maintenance cost, labor cost and downtime loss, to optimize equipment configuration and reduce long-term operation expenditure.

2. Core Process Layout Design of Full rCB Turnkey Line

The complete turnkey workflow follows 6 linked modular units, consistent with JACAN’s mature grinding & classification technical route for recovered carbon black:

Module 1: Raw Material Receiving & Pre-Treatment & Magnetic Separation

This front-end module is critical to protect downstream grinding equipment and cut maintenance costs by 30%–60%.

1. Raw material silo & quantitative feeding: Closed screw conveyor to avoid carbon black dust leakage
2. High-intensity magnetic separation: Double-stage magnetic rollers fully remove residual steel wires and metal impurities from pyrolysis char
3. Primary sieving & coarse impurity removal: Vibrating screen eliminates large hard ash lumps
4. Low-temperature drying unit (optional): Reduce char moisture below 1.5% to prevent agglomeration during grinding

Module 2: Ultra-Fine Grinding & De-Agglomeration System

The core unit to break compact rCB agglomerates while preserving carbon black structural integrity and reinforcement properties.

• Main equipment: JACAN integrated ultrafine grinding mill dedicated for pyrolysis char
• Design targets: Realize micron-level pulverization, avoid over-grinding that damages rCB structure
• Parameter reserve: Variable frequency drive for feeding, adjustable rotor speed to match different raw material traits
• Wear-resistant design: High-alloy liner and grinding media to extend service life and lower spare part replacement frequency

Module 3: High-Precision Aerodynamic Air Classification

Guarantees narrow particle size distribution and stable D90 < 10μm finished powder.

1. Closed negative-pressure air circulation system: Separate qualified fine powder and return oversized particles for re-grinding
2. Multi-parameter adjustable classifier wheel: Real-time air velocity & frequency tuning via intelligent control
3. Multi-stage cyclone pre-collection: Recover most qualified rCB before dust removal, reduce filter cartridge load

Module 4: Dust Collection & Environmental Protection Unit

Full closed negative pressure design to meet global emission standards, zero visible dust leakage.

• Primary cyclone separation + secondary pulse bag dust collector with PTFE coated filter cartridges
• Explosion-proof design: Anti-static filter, pressure relief valve, nitrogen inert protection for ultra-fine carbon black powder
• Waste gas recovery: Hot air recycling back to drying section to cut energy consumption

Module 5: Finished Product Storage, Modification & Automatic Packaging

1. Closed finished silos with nitrogen protection to prevent moisture absorption and oxidation
2. Surface modification system (optional): Improve rCB dispersion for high-end tire and plastic applications
3. Automatic weighing & valve bag packaging line: Dust-free feeding, sealed packaging for transportation

Module 6: Central Intelligent PLC Control System

Realizes full-line unmanned operation, the core of multi-parameter intelligent optimization mentioned on JACAN official website:

• Real-time monitoring: Feed rate, grinding frequency, classifier speed, air volume, bearing temperature, vibration value
• Automatic fault early warning: Over-temperature, overload, filter blockage, abnormal vibration alarm
• Data storage & remote access: 24/7 online expert support to eliminate unplanned downtime

3. Equipment Matching & Modular Skid Design

3.1 Modular Skid Pre-Assembly Design (Turnkey Core Advantage)

All core units are pre-assembled on standardized steel skids in JACAN’s 50,000m² smart production base, including grinding host, classifier, cyclone and dust collector.

• Shorten on-site installation cycle: Complete delivery within 30–60 days, field commissioning finished in 7–15 days
• Reduce civil construction workload: Unified pipeline interfaces, pre-wired electrical cabinets, plug-and-play connection
• Easy capacity expansion: Add grinding/classification modules later without reconstructing the whole plant

3.2 Tiered Equipment Configuration for Different Client Demands

1. Standard economic line: For low-to-medium grade rCB (asphalt, low-end rubber filler), basic magnetic separation + single-stage grinding & classification
2. Premium high-end line: For tire-grade rCB (D90 < 8μm, low ash), double magnetic separation, two-stage grinding, precision air classifier, full intelligent control
3. Large-scale continuous production line (10–15t/h): Multi-set parallel grinding modules, centralized dust removal, automatic batching & packaging

4. Automation & Safety System Design

4.1 Intelligent Control Logic

• SCADA central touch screen: One-click start/stop of the whole line
• Automatic parameter matching: System self-adjust feed quantity and air speed when raw material traits change
• Production data statistics: Hourly/daily output, power consumption, wear part operation record for maintenance planning

4.2 Explosion & Fire Safety Design (Mandatory for rCB Turnkey)

• Whole-line negative pressure operation to prevent carbon black dust accumulation
• Anti-static pipelines, grounding protection for all equipment
• Temperature & smoke sensors, automatic nitrogen inert gas injection when overheating
• Pressure explosion relief ports on grinding mill, cyclone and dust collector

5. Environmental & Auxiliary System Integration

A qualified turnkey solution cannot separate production and environmental treatment:

1. Dust emission: Outlet dust concentration <10mg/m³, meeting EU, US EPA and domestic industrial standards
2. Noise reduction: Sound insulation room for grinding host, silencer on air fans, overall workshop noise below 80dB
3. Waste heat recovery: Recycle hot exhaust air from classification to raw material drying unit, cut power consumption by 15%+
