Introduction of Cement Production Technology

1. The cement production process is mainly composed of crushing and pre-homogenization, raw material preparation homogenization, preheating decomposition, cement clinker firing, cement grinding and packaging process.

2. It is of great significance for ensuring product quality, reduce energy consumption that cement production chose a reasonable choice of grinding equipment ,optimize the process parameters, operate correctly, control the operating system.

Process Flow of Cement Production

Limestone is the main raw material for cement making ,but the general size of the limestone is large.They need to be crushed firstly. In general, limestone processing into cement requires four stages:raw materials to prepare homogenization, pulverized coal preparation, clinker calcination and cement milling .

1. Raw material preparation homogenization: after the crushing of jaw crusher, natural limestone, clay and peculiar raw materials are mixed, and then after the grinding of ball mill, it becomes appropriate ingredients, the quality of uniform raw materials;

2. Pulverized coal preparation: making coal for calcining cement raw materials , must be prepared into coal powder,  providing the required particle size, in order to facilitate the combustion, get enough combustion reaction capacity. The process can be directly into the coal, the processing will use jaw crusher and ball mill and other equipment.

3. Clinker calcination: the lime raw material will be placed in the rotary kiln calcined to partially melt to get lime clinker

4. Cement grinding: the clinker will be added to the appropriate amount of gypsum, mixed material or additives together for the cement, and packaging factory.
