New dry-process cement production line process flow decomposition

Cement is a kind of powdery water-hard inorganic cementitious material, which will become incredibly hard after being fully mixed with water. Silicate cement is one of the most widely used building materials in the construction industry today. Cement production process, divided into wet process, semi-dry process and dry process three processes, is currently more widely used is the dry process to produce cement. Here we do a specific analysis of the dry cement production process.

Cement production process can be summarized as “two grinding and one burning”, “grinding - burning - grinding” process, raw materials need to be crushed first, followed by calcination, in the crushing.

1. Crushing of cement raw material

Raw cement is composed of limestone, clay, iron ore and other materials, raw materials need to be crushed before entering the use, so the crushing process of raw cement is also a mature process of cement production line, crushing process, generally used crusher for the jaw crusher, hammer crusher and impact crusher and so on this structure of the crushing equipment is relatively simple to carry out the primary crushing process.

2. Drying process of cement raw material

The drying process of cement raw material can save more energy and cost for the next calcination process of cement. This step is used is the dryer, dryer make useful rotary, suspended, tower and other different types of drying equipment, generally for the drying of raw cement, commonly used is the rotary dryer, rotary dryer in the drying of raw cement, the internal temperature up to 700 degrees Celsius, for the next step of calcination to prepare.

3.Calcination process of cement raw material

Calcination process of cement is an important process in cement production line, cement raw material will be changed from raw material to cement clinker in the calcination process. The calcining equipment used in the calcination process of cement raw material is generally rotary kiln, of course, there are also some manufacturers use vertical kiln, which is mainly used for semi-dry process production.

The rotary kiln in the new dry cement production process, the new increase in the precalciner kiln and suspension preheating process, so that the cement raw material into the rotary kiln before entering the preheating kiln for preheating, to reduce the rotary kiln heat load and the length of the rotary kiln, and so that the cement raw material in this stage can be fully mixed with the kiln's hot air, thus improving the production efficiency of the rotary kiln for the cement raw material to reach the kiln so that it is quickly calcined to lay the foundation. This will improve the production efficiency of the rotary kiln and lay the foundation for the rapid calcination of the raw cement material in the rotary kiln.

4. Grinding process of cement clinker

Cement clinker is formed after the calcination of cement raw material, and then it will be applied to various industries after ultra-fine grinding process. Cement clinker grinding is generally used in the circle flow grinding process, the use of compression crushing and impact crushing way, can make the cement clinker grinding to improve 40%, reduce 10% of the power consumption. The purpose of cement clinker grinding process is to enhance the cement clinker in the production and use of water slurry coagulation and hardening process.

New dry cement production line not only for customers to save a lot of money, but also greatly improve the production of cement clinker, in order to make its continuous contribution to various industries, of course, in the cement production line, it is easy to cause pollution emissions, this time it is necessary for production enterprises to buy environmentally friendly cement production equipment.
