Depending on a physical state of raw mix, Portland cement clinker production is classified under the following technologies: 
- If a raw mix is prepared as raw mix suspension in water - slurry - wet production technology is being used;
- If a raw mix is prepared as dump granules - semi-wet or semi-dry technology is being used;
- If a raw mix is prepared as dry powder  - dry technology is being used.
Cement production begins with quarrying limestone and its crushing in jaw and hammer crushers. Clay is the other component of cement production. Clay is being received from quarry and modified to wet suspension - clay slurry - in a clay wash mills. Clay slurry is being pumped to raw mills through intermediate volumes; crushed limestone and raw mix corrective materials- iron ore and sand - are also fed to raw mills. Raw materials are grinded and blended in the raw mill, transforming them to the quite fluid smooth suspension, having ****8 % of moisture and called slurry. Before feeding it to a rotary kiln the slurry is being stored and constantly blended in containers, called slurry basins.
