How Cement Is Made

This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller. The crushed rock is combined with other ingredients such as iron ore or

The Making of Iron Steel

Iron ore as mined is a combination of iron with oxygen and various other unwanted substances generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron a process which is mostly carried out in a blast furnace using coke as both a fuel and reducing agent.

Iron and Steelmakingvsb

for iron led to intensification of its production. Air was blown into a furnace and the height of the furnace was increased. Temperature at the bottom of the furnace was being increased until iron was melted. The melt was carburized and the manufactured iron ceased to be malleable. Thereby iron production is divided into two stages

Cement Manufacturing ProcessCivil Engineering

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium) sand and clay (silicon aluminum iron) shale fly ash mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
