Nowadays, the dry process is the most popular cement making process which is widely adopted by cement plants all over the world for its great advantages in energy saving and environmental protection.

Cement production will experience several procedures which include raw materials blending process and burning process, cement clinker grinding process, and packaging process. Cement raw material and cement clinkers mainly contain four oxides: calcium oxide or lime (CaO), silica (SiO 2 ), alumina (Al 2 O 3 ), and iron oxide (Fe 2 O 3 ).

Cement is the substance which holds concrete together, which means that it is extremely widely used in our society. It has been manufactured in New Zealand for more than 100 years, and during this century production has increased one hundred-fold. Portland cement (the only type of cement in common use today) is manufactured in a four step process.
