The clinker for each one of these processes has particular characteristics that differentiate it from production methods and specific heat consumption; data in Table 1 correspond to clinkers for producing grey cement. For white cement the specific consumption is between 1800 and 2200 kcal/kg of clinker with the wet method.

Control of cement clinker production in a wet process

The semi-wet process of producing cement clinker involves using a slurry of raw material and water in which the water content is in the range of approximately 15% to 20%. The kiln is equipped with filters that remove a portion of the water through a process known as slurry dewatering.

Manufacturing process of cement Wet Process

2020-7-9  The wet process of cement manufacturing is divided into a number of stages. a) Raw material extraction. b) Grinding. c) Proportioning and mixing and preparing composition based on the raw material purity. e) Preheating the composition. f) Burning the composition in a kiln to form clinkers. g) Clinker cooling with gypsum addition and grounding to fine powder.

Wet Process of Cement Manufacturing Cement Wet

Wet Process. The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker.

Clinker Production Clinker Manufacturing Cement

The production of cement can be divided into dry process and wet process, while because of the high output, low heat consumption and steady running, the dry process has become the most commonly used manufacturing method in cement plant, mainly includes three models: dry process rotary kiln production, suspension preheating kiln production, and pre-decomposition kiln production.

Since raw materials can be homogenized and the mixing ratio can be corrected after grinding, this process is relatively simple.

Draft guidance on cement clinker production facilities

2015-6-18  The basic chemistry of the clinker production process begins with the decomposition of calcium carbonate (CaCO 3 ) present in the raw material at about 900 °C to leave calcium oxide (CaO, lime) and liberate gaseous carbon dioxide (CO 2 ); this process is known as calcination.
