While it is being heated various chemical reactions take place to form the major mineral constituents of Portland cement. The powder from the dry process doesn’t contain much moisture, so can be dried in a preheater tower. As it falls through the tower (which takes 30 seconds) it is heated from 70 to 800oC.

Research behind the solution prior to the building of the Holnam backward-curved preheater fan, Robinson had conducted an extensive study into the problem of build-up in cement factory fans. The study entailed two approaches: 1) information gathering and 2) a laboratory simulation of cement plant build-up conditions.

The basic dry process system consists of the kiln and a suspension preheater. The raw materials, limestone and shale for example, are ground finely and blended to produce the raw meal. The raw meal is fed in at the top of the preheater tower and passes through the series of cyclones in the tower.

A rotary kiln of 6 x 100 m makes 8,000–10,000 tonnes per day, using about 0.10-0.11 tonnes of coal fuel for every tonne of clinker produced. The kiln is dwarfed by the massive preheater tower and cooler in these installations. Such a kiln produces 3 million tonnes of clinker per year, and consumes 300,000 tonnes of coal.

Cement manufacturing process is mainly divided into three stages, namely, raw meal preparation, clinker burning and cement grinding. Cement Manufacturing Coming soon, more information about cement manufacturing including the industries sustainable and safety measures.

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.

Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.

improving process economics. Preheater and precalciner kiln systems often have an alkali bypass system between the feed end of the rotary kiln and the preheater tower to remove the undesirable volatile constituents. Otherwise, the volatile constituents condense in the preheater tower and subsequently recirculate to the kiln.
