Hey everyone,

Daniel from Ready Mixer here.

Today we are going to talk about cement manufacturing and how cement is produced. 

To start, cement’s raw materials are mined out of a quarry and consist of limestone, clay, and shale. 

They are then put in a kiln and heated to temperatures up to 1450 degrees Celsius to form clinker.

Clinker is a dark grey nodule or ball of heated limestone and clay from the kiln.

Clinker is then grounded and gypsum is added during the grinding process to finally form cement. 

Gypsum is a retardant used to slow the process of hardening for cement. 

The cement is a binding agent between sand and stone. 

There are different types of kilns such as rotary and shaft kilns. These kilns can be wet and dry process kilns. The difference between a wet and dry process kiln is that the wet kiln brings the meal wet into the kiln. The dry process kiln brings the meal hotter into the kiln. 

Whether you are buying cement in bulk or by the bag, I hope this helps you understand the process of how cement is produced.
