carbon black | chemical | industries | hosokawa micron powder systems

Carbon Black is a material produced from the incomplete combustion of hydrocarbons such as heavy oil and other petroleum products. It is an essential component in tires, rubber, plastics and liquids, enhancing these products by adding strength and durability.

Most Carbon Black is produced in an atmosphere controlled furnace where fuel is introduced into a hot gas stream that produces sufficient heat to vaporize and pyrolyze the fuel into ultra-fine carbon particles. At this point the carbon black is an inconsistent mixture of fine particles and agglomerates referred to as grit. These grit particles are an unwanted byproduct, and can adversely affect the physical properties of the rubber and plastic products.

Traditionally, devices like hammer mill (like the Hosokawa Mikro-Pulverizer) were used to reduce grit levels to 100 to 200 PPM +325 MESH. Though this process was cost effective and efficient, the final material quality was limited. Hosokawa recognized carbon black manufacturers had a market for much higher grade, nearly grit free materials.

In recent years, Hosokawa Micron Powder Systems released a new milling system capable reducing grit levels to a fraction of what was previously available. The new milling system offers many new advantages over competing technologies:

The newly developed Mikro-eACM Carbon Black Air Classifier Mill greatly transcend the performance of conventional hammer mills. It offer superior grit reduction capabilities, are more energy efficient and have lower costs of operation.

recovered carbon black | hosokawa micron

The Hosokawa Group has developed a process for the sustainable recovery of Carbon Black from used car tyres. By performing a number of steps after pyrolysis, the process results in dust-free granular material that can be dosed accurately. It is ready for immediate use in the manufacture of new car tyres or other rubber-based products.

Many recycling companies that handle car tyres are keen to find a way to recover Carbon Black from the rubber. This 'black gold' must undergo several processing steps after pyrolysis before it can be used as recovered Carbon Black (rCB). "We've developed an efficient and sustainable process for that," says Marc Jacobs, Team Manager Chemicals, Minerals & Metals (CMM) at Hosokawa Micron in Doetinchem, the Netherlands. "Our new processing line makes it easy for recycling companies to recover top-quality Carbon Black from car tyres. Manufacturers of car tyres and other rubber-based products can then immediately use the resulting granules in their production processes."

Hosokawa Group developed the new, integral process by combining knowledge, experience and equipment from a number of its subsidiaries around the world. "In particular, this project involved Hosokawa Alpine, Hosokawa Micron and Hosokawa Solids Solutions," continues Jacobs. "We also worked in close collaboration with a number of partners to ensure that our customers the recycling companies can depend on an efficient processing line in which all the machinery and systems are optimally aligned. Moreover, this 'one-stop shop' approach means that each customer has a single point of contact."

"Thanks to our expertise, we're able to produce rCB with precisely the properties that car tyre manufacturers are looking for. They require dust-free and free-flowing granular material that is easy to dose," he adds. In the preparatory process, the used tyres are shredded and ground, and the steel content is reduced as much as possible. The material then undergoes pyrolysis. The oil and gas produced in this process is reused elsewhere, and the remaining material forms the basis for Hosokawa Group's rCB finishing process. However, the particle structure of the rCB pellets must be altered in order for them to be used successfully.

The pyrolized material is transformed into top-quality rCB granules in three consecutive steps: fine grinding, agglomeration and drying. The first step fine grinding is one of Hosokawa Alpine's specializations. The fine grinding step can be performed by two different grinding technologies: either with the Fluidized Bed Opposed Jet Mill TDG or the Mechanical Classifier Mill ACM.

TDG Jet Mills offer end product fineness in the range of d99 = 5-15 microns and coarser if required, even at high throughput rates. The TDG process also ensures the easy removal of impurities like metal wires during the grinding process. The ACM is limited regarding ultra-fine end product qualities. We recommend the ACM for coarser types at d97 = 20-40 microns. But the decision for a certain milling technology also depends on the product abrasiveness. For rCB types with a high ash content, the TDG solution has clear advantages in terms of OPEX.

It is not unusual for grinding lines to have a capacity of 1 ton/hour or more. Bearing in mind that the bulk density of the ground product is approximately 80-120 grams per litre, the process can soon involve volumes of more than 10 m/hour. At this stage, the Carbon Black is a dusty material with poor flow properties and a tendency to settle. "As a result, special expertise is required for handling and interim storage," explains Jacobs. "That expertise comes from our sister company Hosokawa Solids Solutions, which supplies the systems for trouble-free transfer of the semi-finished material between the various process steps."

Next, the ground Carbon Black is agglomerated and then dried: two disciplines in which Hosokawa Micron excels. The agglomeration step can be performed using the Flexomix vertical high-speed mixer. The rCB is dosed into the Flexomix together with precisely the right amount of a binder (usually water). The moistened granules emerge at the bottom of the machine. The flexible wall of the mixing chamber is continuously massaged on the outside to prevent the product from sticking to the inside.

"Alternatively, it's possible to agglomerate the product using a Pin Mixer. This is a horizontal high shear mixer from one of our partners, the American company Mars Mineral. The pins on the central rotor shaft create a helix that transports the product at the same time. With the right amount of binder, the Pin Mixer is able to produce strong, dense, spherical particles which can be transported pneumatically without cracking. Both the Flexomix and the Pin Mixer operate as continuous processes."

The resulting granular material is dried in a Hosokawa Micron static fluid-bed dryer (with or without a vibrating or shaking system) that has been specially designed for drying rCB granules. It is positioned directly under the mixer. Hot drying air is blown upwards through the holes of the perforated plate, evenly distributing the granules. Thanks to the slight incline, the product gradually moves into the cooling zone. After being sieved as a final check, the rCB is stored or packaged.

"Our interdisciplinary approach has resulted in an integral processing line to produce a free-flowing, dust-free granular material with the right properties in terms of particle structure," concludes Jacobs. "This solves a problem for recycling companies and means that the rCB granules are immediately ready for use by tyre manufacturers in the production of new tyres."

Car tyre manufacturers are keen to improve the sustainability of their production processes, including by stimulating the circular use of raw materials. Various government subsidies are available to support such goals in Europe and a growing number of companies are recovering Carbon Black from used tyres. Carbon Black not only gives car tyres their deep black colour, but also makes them robust and durable. By using recovered Carbon Black (rCB), tyre manufacturers can reduce their need for virgin material, which is produced by the partial combustion of hydrocarbons into soot. The production of rCB is significantly better for the environment since it does not involve the combustion of fossil fuels.
