Achieve capacity and energy benefits in your preheater

The design of the preheater system is a major factor for efficient cement production. Its design and complexity have evolved rapidly thanks to growing production volumes and increasing energy costs.

Today’s dry process kilns, coupled to multiple-stage preheater systems, offer 20 times more capacity than similarly sized wet-process kilns. The thermal efficiency and capacity of a modern cement-making operation is very high – but can be even higher with the right refractory solutions.

In this section, we deal specifically with the following areas of the preheater:

• Cyclones (including connecting ducts)
• Calciner
• Smoke chamber and riser ducts
• Meal pipes
