Recovered Carbon Black rCB Processing Grinding Mill Machines

1. What is rCB?

Recycled carbon black (rCB), usually derived from the high-temperature pyrolysis of waste tires, is a relatively new, sustainable class of raw material products that can be used in products such as rubber, plastics and pigments.  

2. How to process rCB?

High-temperature thermal cracking is an effective recycling method for the harmless and resource-based treatment of waste tires that has developed rapidly in recent years.

The main products of the thermal cracking process are pyrolysis oil, pyrolysis carbon black (rCB), and syngas. and steel wire.

The primary carbon material (char) obtained by cracking cannot be directly used as a rubber or plastic filler.

In order to improve and improve the performance of rCB and maximize the benefits of the thermal cracking process, the primary carbon material is usually ground and processed. A series of post-processing processes such as grinding, modification and granulation.
   

3. What grinding mill is suitable for processing rCB?

Recycling carbon black grinding mills (pyrolysis carbon black mills) include Raymond mills, pendulum mills, vertical mills, and ultra-fine vertical mills. If the rCB of 80-325 mesh is processed within 20 tons in one hour, it is recommended to choose an economical pulverizer (Raymond mill, pendulum pulverizer). If you want to process more than 20 tons, you can consider Vertical mill, because the production capacity of vertical mill is much larger than that of Raymond mill.

To produce recycled carbon black powder with fineness in the range of 325-2500 mesh, with a production capacity of more than 20 tons, it is recommended to use HGM ultra-fine vertical grinding mill to configure the production line. The configured multi-head grading and powder separation system can adjust the fineness of powder in the range of 325-2500 mesh at will.

The following will mainly introduce two of the most commonly used recycled carbon black mills: Raymond mill and ultra-fine mill.

2. HGM Ultrafine grinding mill for rCB

HGM Ultrafine grinding mill is also named HGM micro powder grinding mill. It can be used for pumice, activated carbon, limestone, calcite, marble, talc, barite, gypsum, dolomite, bentonite, mica, pyrophyllite, sepiolite, diatomite, graphite, alumite, fluorite, potassium feldspar , Phosphate rock, pigment and other more than 100 kinds of non-flammable and explosive materials with humidity less than 6% and Mohs hardness not greater than 6 are processed into ultra-fine powder. The particle size of the finished product is 325-2500 mesh (0.044-0.005mm).

Recovered the carbon black short as rCB mostly from the waste tires after pyrolysis carbon black, which is different from the virgin carbon black. But after refining by the HGM micro powder grinding mill. It can reach N series grade as semi-reinforcement properties at economical prices. rCB has been used as the reinforcing agent in tires. 

In many many areas it can be used as the substitution for Virginia carbon black, such as the passenger car light truck tire tread. heavy duty conveyor belts, high-pressure hoses, transmission belts, industry agriculture tire tread and carcass, rubber sheeting, wire cable jacketing gaskets seals rubber roofing, passenger car light track tires sidewalls, truck car tire under threads, truck tire body and a belt prices.  As the raw materials and energy resources price keep increasing.
