It was developed for other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2-3% percent of GYPSUM. Several types of Portland cement are available.

Clinker Grinding Unit INTRODUCTION The cement grinding process mainly includes cement homogenization and batching, cement grinding, cement bulk loading and packaging. It is divided into three systems: cement grinding system, powder separation system and packing system.
