The cement production line is the cement equipment production line composed of a wide range of devices, which mainly includes crushing (crushing equipment) homogeneous preparation, raw material preparation homogenization, precalcining system, the sintering of cement clinker, and the cement grinding and packaging process.
With the rapid development of China's economy in recent years, the country increases investment to perfect the basic service facilities, thus it has brought a lot of opportunities for breakneck development of cement industry. China's cement industry has a fairly large scale through the rapid development in recent years. The cement production enterprises have turned into multiple industry from a single cement production. At the same time, the longitudinal integration of sand aggregate, concrete, cement products has become an inevitable trend in the development of the industry, and the industry will take cement as the core, take, concrete as leverage to do big industry chain of building materials.
The cement production equipment can be divided into dry process cement production line (including semi-dry method) and wet cement production line (including the semi-wet method) according to different preparation methods of the raw material.
First, let us talk about the dry cement production process. Dry and grind the raw material or you can dry the material. After the material is grinded into raw material powder, feed it to the dry kiln to calcine it into clinker. The raw material powder can be also added some water to make it into raw material ball and send it into the Lepol kiln to calcine into clinker, which is called semi-dry method. It is still one kind of dry production.
Second, let us make a brief introduction of wet cement production process for you. After the raw material with water is grinded into raw slurry, you can feed it into the wet kiln to calcine it into clinker. You can also dehydrate the raw material produced through wet method, which is called semi-wet method. It is still a kind of wet production.
The cement equipment include cement rotary kiln, cyclone preheater and grate cooler. Cement rotary kiln is the main equipment for calcining cement clinker which has been widely used in cement, metallurgy, chemical and other industries. The equipment consists of the cylinder, bearing devices, with gear wheel bearing devices, gear, activities kiln head, kiln seals, combustion devices and other components. The rotary kiln has a simple structure and reliable operation.
In the cement production process, most of the raw material should be crushed, such as limestone, clay, iron ore and coal. Limestone is the largest amount of production of cement raw materials.
