Grenzebach’s Dross Box ensures precise and reliable handling of the glass ribbon during its critical transition from the tin bath to the annealing lehr in float glass production.

Featuring a simplified and fast height adjustment of the lift-out rollers, the Dross Box allows an individual adaptation of curve geometry to meet specific production needs. This not only enhances process reliability but also provides greater flexibility for manufacturers, particularly when producing varying glass thicknesses.

The Dross Box can be equipped with different typs of roller types—including steel, coated steel, and ceramic—giving manufacturers the flexibility to choose the most suitable option.

Advanced insulation and optimized atmosphere separation guarantee consistent temperature distribution across the glass ribbon while minimizing heat loss, crucial for maintaining high product quality and energy efficiency.

Designed with easy maintenance and improved operator safety in mind, the Dross Box allows for quick replacement of graphite bars. Continuous cleaning of the rollers is achieved through multi-part graphite bars with pneumatically adjustable contact pressure, ensuring a clean process.

With its innovative design, adaptability, and performance-oriented features, Grenzebach’s Dross Box establishes new benchmarks for precision, and efficiency in float glass production.
