Dry Process Cement Plant for Sale

Cement Dry Processing Operation

Two different processes, "dry" and "wet," are used in the manufacture of portland cement. When rock is the principal raw material, the first step after quarrying in both processes is the primary crushing. Mountains of rock are fed through crushers capable of handling pieces as large as an oil drum. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller.

Dry Process Cement Plant for Sale

In modern time, the new plant uses dry process technology to produce cement. Limestone and silica-rich sand or rock is quarried and crushed, and transported to storage stockpiles near the kiln where pre-blending takes place.

The raw materials are dried, ground and mixed to form a fine, homogenous powder, with moisture content of less than one percent. This powder is fed into the kiln where the heat promotes the necessary chemical reactions.

The kiln exhaust gases are the main source of heat used to dry the raw materials. This is known as 'dry process' technology because no water is added to the ground raw materials. It is the process used by modern cement manufacturing plants.
