- Why Is Clinker Ground Into A Fine Powder
The newly formed clinker has unique chemical properties that impact the cement's strength and other key properties. Step 4: Grinding and Preparing the Cement. After the production of the clinker, the next step is preparing the cement powder. Grinders break down the clinker into a fine powder.
