The process of clinker manufacture has evolved massively over the last decades. Back in 1843 when William Aspdin invented the technical process of clinker manufacture in a rotary kiln, the production was primarily driven by the burner. With all the developments coming in the subsequent years, especially the precalciner and the external combustion chambers, the main burner (as it has been called since then) only takes over about 45% of the thermal input.
Aerzen is significantly expanding its product portfolio in the higher-pressure range and has added innovative compressors from the standard segment for differential pressures of up to 13 bar.
In recent years, the adoption of alternative fuels has become a key factor in the sustainable evolution of the lime industry. In particular, the use of biomass is emerging as an effective solution to reduce environmental impact while ensuring a more flexible and resilient energy supply.
Starlinger presents technical solutions for closed-loop systems in woven plastic packaging. “Plastic packaging is the packaging of the future,” stated Harald Neumüller, CSO of Starlinger.
The new pilot plant for tempered clays at the Rohrdorf cement plant successfully went into operation at the beginning of July. In the plant, raw clay is activated (“tempered”) through thermal treatment. The aim of the plant is to research tempered clays, as these can be used as a lower-CO₂ alternative to clinker, the main component of cement.
Net negative emissions by 2040: Five key levers are required to pave the way to CO2 negativity in Great Britain’s lime industry. In an interview with ZKG Cement Lime Gypsum, Mike Haynes and Jon Flitney further outline the details of the MPA Lime Net Negative 2040 roadmap.
