Cement Manufacturing Plant
Cement production is a complex process. It requires various processing techniques and many different types of equipment. Cement manufacturing is generally accomplished in four steps: quarrying, raw material preparation, clinkering and cement milling.
Zenith has been dedicated in cement manufacturing technology for long history. As a professional supplier and manufacturer of processing plant, we provide high performance cement manufacturing plant for sale including quarry machine, mining and extraction plant, crushing machine, grinding mill, rotary kiln, and processing equipment.
Step 1 - Quarrying
Limestone and cement rock such as clay or shale are quarried and delivered to the cement production line. These rocks contain raw materials for cement manufacturing such as lime, silica, alumina and ferrous oxide.
Used plant: includes drilling and blasting machine, extraction plant, and quarry crusher etc.
Step 2 - Raw Material Processing
The step can be completed in dry or wet process. The dry process uses more energy in grinding but less in the kiln. The quarried clay and limestone are crushed separately until nothing bigger than a tennis ball, and then grinded into find particle size of less than 90µm in diameter.
Used plant: jaw crusher, impact crusher, cone crusher, mobile crusher, vibrating screen etc.
Step 3 - Clinkering
Clinkering is characteristic of Portland cement production. The finely grinded raw materials are then dried, heated and fed into a rotating kiln, and then cooled down again.
Used plant: rotary kiln, cooler.
Step 4 - Cement Milling Process
To produce the final product the clinker is mixed with gypsum, which is added as a set retarder, and ground in cement grinding plant. The cement grinding process is highly energy consuming. In the end, the clinker is processed into useful cement.
Used plant: includes ball mill, high pressure mill, ultrafine mill, trapezium mill, vertical mill, roller mill etc.
