Types of Cement Manufacturing Processes. There are two main manufacturing methods: 1. Wet Process (Older Method) Raw materials are mixed with water to form a slurry. The slurry is heated in kilns to form clinker. More energy-intensive, but provides better homogenization. 2. Dry Process (Modern Approach) Raw materials are ground into dry powder.
