Dosing machine for fly ash

The ZKW Otterbein cement and lime plant in Großenlüder recently upgraded its facilities with an advanced dosing machine from Carbotechnik. Specifically, this historic family-owned company blends fly ash into its production processes to achieve precise material characteristics. Consequently, fly ash improves both the strength and long-term durability of the final building materials. Therefore, the facility requires exceptionally reliable systems to maintain its high quality standards.

Strategic benefits of the new dosing machine

To achieve this, the newly installed dosing machine delivers a continuous and highly precise feed rate of up to 5,000 kg/h. Indeed, handling fine secondary materials like fly ash presents major challenges due to dust generation and varying material densities. As a result, Carbotechnik developed a custom-designed feeding system that guarantees a completely uniform, pulsation-free material flow.

Furthermore, this specialized system offers an incredible degree of operational flexibility. Specifically, Carbotechnik engineered the dosing machine to process both abrasive fly ash and dry lignite dust. Since the physical properties of these two materials differ significantly, the mechanical design requires highly advanced engineering. Consequently, this versatile setup allows ZKW Otterbein to switch between materials seamlessly.

Overcoming industrial challenges

In addition to handling different materials, the engineering team had to address strict explosion protection requirements. Because processing fine dust particles carries natural safety risks, Carbotechnik built the system according to demanding safety standards.

Ultimately, the successful commissioning of the dosing machine secures ZKW Otterbein’s competitive edge in sustainable cement production. Therefore, the plant now benefits from maximum dosing accuracy, lower operating costs, and absolute process reliability.
