Recycling And Processing Of Waste Tyres, The Pyrolytic Carbon Black Grinding And Granulation Process Plays A Crucial Role. With The Increasing Emphasis On Environmental Protection And Resource Recycling, Pyrolytic Carbon Black Is Not Only Widely Applied In The Rubber Industry. It Also Holds Significant Economic And Environmental Value. This Article Will Provide A Detailed Analysis Of The Pyrolytic Carbon Black Grinding And Granulation Process. You Will Understand How This Process Improves Product Quality And Stability While Enabling Efficient, Continuous Production.

 Pyrolytic Carbon Black Grinding And Granulation Process

 HIGH-TEMPERATURE PYROLYSIS 

Process Principle

 Waste Tyres Undergo Pyrolysis At High Temperatures Ranging From 280°C To 350°C In A Low-Oxygen Environment. In Tyre Pyrolysis Plant, The Main Components Of The Waste Tyres, Such As Natural Rubber, Synthetic Rubber, Carbon Black, And Vulcanizing Agents, Produce The Following Key Products:

 Carbon Black

 A Black Solid Material Formed From The Carbon Black And Other Inorganic Substances (Such As Fillers, Vulcanizing Agents, Etc.) In The Tyres Through The Pyrolysis Reaction.

 Pyrolysis Oil

 Produced From The Organic Components In The Tyre, Such As Rubber Molecules And Plastic Components, It Mainly Consists Of Petroleum-Based Compounds, Which Can Be Used As Fuel Or Further Refined.

 Syngas

 Composed Of Hydrogen, Carbon Monoxide, And Small Amounts Of Carbon Dioxide And Methane, Which Can Be Used For Energy Recovery.

 CORE PROCESS

 Minimize The Contact Time Between Carbon Black And Oil Gases. It Can Reduce The Residual Oil Content In Carbon Black And Improve Its Toluene Transparency.

Precisely Control The Pyrolysis Reaction Temperature. It Can Reduce The TPH (Total Petroleum Hydrocarbons) Content In Carbon Black.

 Control The Oxygen Concentration During Pyrolysis. It Can Prevent The Formation Of Incomplete Pyrolysis Products, Such As Residual Oil And Impurities In The Carbon Black.

 COARSE GRINDINGProcess Principle

 The Pyrolytic Carbon Black Particles Are Relatively Large After Pyrolysis. Typically, A Vertical Grinding Mill Is Used To Grind The Carbon Black Powder To 300-800 Mesh For Subsequent Processing.

 The Coarse Grinding Process Includes The Following Steps:

 Crushing

 Large Carbon Black Particles Are Rapidly Broken Down Into Smaller Particles Through Physical Impact And Compression.

 Grinding

 The Grinding Roller And Grinding Plate Work Together Through A Pressing Action To Further Refine The Carbon Black To The Required Particle Size.

 Classifying

 Centrifugal Force Or Air Classification Devices Are Used To Separate The Carbon Black Particles That Do Not Meet The Required Particle Size.

 Dust Removal

 A Pulse Dust Collection System Is Employed To Handle Dust, Ensuring A Clean And Safe Production Environment.

Core Process

 Precise Control Of Particle Size During The Grinding Process. It Ensures That The Powder Meets The Requirements For The Subsequent Granulation Process.

 Ensure Uniform Particle Distribution. Uneven Particle Sizes Can Lead To Instability During The Granulation Process.
