New TDG 1250 mill size
Maximum throughput for recovered Carbon Black processing
Hosokawa Alpine is expanding its portfolio of fluidized bed opposed jet mills with the new TDG 1250 size. For the processing of recovered Carbon Black (rCB), the mill enables throughputs of up to five tons per hour at fineness levels of d97 < 10 µm, setting new standards for cost-efficient large-scale production plants.
The demand for high-quality recovered Carbon Black is increasing worldwide. As a sustainable alternative to virgin carbon black derived from fossil resources, rCB is becoming increasingly important in the tyre recycling, rubber, and plastics industries. Reliable fine grinding is essential to ensure defined product characteristics and consistent product quality for further processing.
For this application, Hosokawa Alpine’s TDG fluidized bed opposed jet mill has established itself as a proven solution over many years. More than 20 TDG systems for the processing of recovered Carbon Black have already been installed worldwide. Most of these systems are based on the proven TDG 800 size, covering production capacities of approximately 1.5 to 2.5 tons per hour at a fineness of d97 = 10 µm.
Growing demand for higher production capacities
As the rCB market continues to expand, the demand for larger production capacities is also increasing. In response to this trend, Hosokawa Alpine has developed the new TDG 1250. This larger mill design has been specifically engineered to meet the growing requirements of modern rCB production facilities. It enables throughputs of up to five tons per hour at the fineness levels typically required for recovered Carbon Black, d97 < 10 µm – while delivering the same high product quality and process reliability for which TDG technology is renowned.
The key benefit for plant operators is the ability to achieve high production volumes with a single process line. Whereas multiple parallel grinding circuits were previously required, the TDG 1250 can often provide the necessary capacity within one line. This significantly reduces capital expenditure (CAPEX) for additional equipment, peripherals, and infrastructure. At the same time, operating expenses (OPEX) are minimised, as fewer units need to be operated, maintained, and monitored.
With the introduction of the TDG 1250, Hosokawa Alpine further strengthens its position as a leading technology partner for the processing and refinement of recovered Carbon Black. The new mill size enables plant operators to respond to dynamic market growth while benefiting from highly economical production.
