Cement clinker is an indispensable building material in all major construction industries. Cement clinker uses limestone, clay, and iron raw materials as the main raw materials. It is a product that is calcined through physical processing and then crushed. In the construction industry, there are many products. Construction cement tailings, these tailings can still realize their reuse value after being reprocessed by crushing equipment, so some people can't help but ask: What equipment can crush cement clinker? How is cement made? Next, Zhengzhou Global Heavy Machinery will answer your questions one by one:
How to choose equipment for processing cement clinker?
1. Fine crusher
The tertiary crusher, also known as the fine sand making machine, is a third-generation new tertiary crusher with high efficiency, energy saving and emission reduction. When the material enters the tertiary crusher, it needs to go through two passes and enter the crushing chamber to complete a transformation, breaking large materials into small pieces. Then challenge the second level and enter the second fine crushing chamber to complete the crushing until it is discharged from the discharge port. It is not only suitable for cement clinker, but also for fine crushing of granite, basalt, limestone, river pebbles, etc.
2. Roller crusher
The double rollers of the double roller crusher are equipped with roller sleeves. The surface of the roller crusher has very strong heat resistance and wear resistance, which allows the equipment to maintain low-speed rotation and extrusion of cement clinker with relatively little wear and tear on the equipment and strong adaptability. . Easy maintenance and long service life.
3. Hammer crusher
The hammer crusher integrates three crushing methods: impact, counterattack, and impact. It has high efficiency in one-time crushing and molding, increases output by 30%, and saves investment costs by 40%. It has dual functions of stone crushing and shaping, one top jaw crusher and two impact crushers. The finished product has good particle shape and uniform size, and the discharge particle size can be adjusted freely.
The above are most of the machines and equipment on the market that can process cement clinker. The specific equipment to choose depends on the customer's specific production line configuration and the materials to be processed.
How many steps are there in the cement production process?
1 Crushing and pre-homogenization: Use a crusher to crush cement production raw materials such as limestone, clay, iron ore and coal, and use science and technology to preliminarily homogenize the raw materials during the storage and retrieval process.
2 Raw material preparation: Reasonable selection of grinding equipment and process flow, optimization of process parameters, correct operation, and control of operating systems are of great significance to ensuring product quality and reducing energy consumption.
3. Raw meal homogenization: In the new dry process cement production process, stabilizing the raw meal composition entering the pit is the prerequisite for stabilizing the thermal system of clinker firing. The raw meal homogenization system plays a check role in stabilizing the raw meal composition entering the pit.
4. Preheating decomposition: mainly includes material dispersion, gas-solid separation, pre-decomposition and other steps.
5. Firing of cement clinker: In the rotary kiln, the carbonate further rapidly decomposes and a series of solid phase reactions occur to generate minerals in the cement clinker.
6. Cement grinding: It is a process in the cement production process, and it is also a process that consumes a lot of electricity. Its main function is to grind cement clinker to a suitable particle size to form a certain particle gradation, increase its hydration area, accelerate the hydration rate, and meet the cement slurry coagulation and hardening requirements.
