During the process of cement production, it needs grinding three tons materials for product one tone portland cement (including all kinds of raw materials, fuels, clinkers, compound material, gypsum). According to the statistics, the cement dry process production line grinding operation needs to consume 60% power of the the whole plant, among it the raw material grinding occupy above 30%, the coal grinding occupy about 3%, the cement grinding occupy about 40%. Therefore, we should reasonable select grinding equipment and technological process, optimize technological parameters, proper operation, control work system. And this will have great significance on ensuring production quality and reduce energy consumption.
The main materials of cement production are limestone and clay, they turn into raw materials through crush, burdening, grinding by vertical mill, then turn into clinker by feeding into the cement rotary kiln, and then put in appropriate gypsum, some mixed materials or admixture, then turn into cement through roller press and cement mill. At last transport out of the plant after packaging by package equipment or bulk cement loaded. For different raw material preparation method, the production line can be divided into dry process and wet process.
Cement dry process cement production technological process: Is the approach to dry raw material and grinding or dry raw material powder feed into the dry process rotary kiln. There is also an approach named semi- dry method, which needs put in appropriate water into the raw material powder to make into the raw material ball, and then feed in into the Lepol kiln, it is also belongs to one of the dry process.
The main advantages of dry process is low heat consumption, the heat consumption of dry process kiln with preheater is 3140-3768J/KG. The weakness is raw material ingredient not well-distributed, the workshop huge dust and high powder consumption.
Cement wet process cement production technological process: Is the way to grinding the raw material and water into raw material thick liquid and then feed into the wet process rotary kiln. There is also an approach to dry the raw material thick liquid into the raw material chunk, then feed into the kiln, which named semi-wet process, also belongs to wet process.
The advantage of wet process is easy operation, easy control of raw material ingredient, high quantity of production, convenient convey of thick liquid, little dust of workshop etc. The weakness is huge heat consumption, usually the clinker heat consumption is 5234-6490J/KG.
