KHD built the first preheater (Germany, Bomke & Bleckmann), a starting point of a new era of optimising the heat consumption of the clinker pyro-processing system. At the time, this technical revolution reduced the heat consumption by nearly 50 percentage. Modern cyclone pre-heaters from KHD have considerably reduced the heat consumption of kiln lines, while ensuring availability and operational safety. The raw meal processed in the kiln first passes through the pre-heater absorbing the heat content of the kiln and PYROCLON – gases minimising the heat consumption of the system.

Features:

270- inlet spiral with improved inlet geometry.
An optimum of separation efficiency and pressure drop from immersion tube, separation efficiency of top stage approx. 95%.
Steep cones to minimize coating tendency.
Low gas flow velocities in the immersion tubes between 10 and 15 m/sec.
Pre-heaters with modern designed cyclones produce low pressure drops and are high in separation efficiency. This also leads to improvement in energy efficiency of the system.

The American Cement Association projects a nearly 1Mt annual increase in US cement demand over the next three years, driven by the surge in AI data centres. Consumption by data centres is expected to grow from 247,000 tonnes in 2025 to 860,000 tonnes by 2027. With over 5,400 AI data centres currently operating and numbers forecast to exceed 6,000 by 2027, the association cautions that regulatory hurdles and labour shortages may impact the industry’s ability to meet demand.

GoldCrest Cement will build a greenfield integrated plant with a 3.5Mt/yr clinker capacity and 4.5Mt/yr cement capacity. GoldCrest Cement appointed Humboldt Wedag India as engineering, procurement and construction contractor in March 2025 and targets completion by March 2027. It has signed a 40-year supply agreement with Gujarat Mineral Development Corporation for 150Mt of limestone from its upcoming Lakhpat Punrajpur mine in Gujarat.
