Modern cement manufacturing is inseparable from a full set of high-quality cement equipment. Many capable cement enterprises choose to set up large cement production lines. In any case, quality cement kilns are essential equipment in the cement production process. As the heart of the cement plant, cement kiln is mainly responsible for the calcination of cement clinker. Its technical performance and operation condition, to a large extent, determine the quality, output, and cost of cement products, which is the potential influence factor of cement enterprise benefit.
Cement kilns can be classified into cement shaft kiln and cement rotary kiln. The shaft kiln is suitable for small scale cement plants, large and medium cement plants often use cement rotary kiln. What we called rotary kiln cement plant is the cement manufacturing plant with rotary kiln as calcining equipment and other cement equipment as auxiliary equipment. At present, most cement enterprises around the world adopt rotary kiln cement plants for cement production. It occupies more than half the market by a very significant advantage. Why they choose the rotary kiln cement plant? And how do we purchase a rotary kiln cement plant? The following is what we discussed in details.
Advantages Of Rotary Kiln Cement Plant
The rotary kiln cement plant can be divided into dry method cement plant and wet method cement plant. Their main difference lies in the cement rotary kiln. Raw meal calcined in the wet method kiln is a slurry containing 32% to 40% moisture, so the kiln body is longer and the clinker produced is of high quality with small dust pollution. On the contrary, the raw meal in dry method kiln is a powder with less than 1% water content. The kiln size is relatively small and the thermal efficiency is high. At present, these two kinds of cement plants are commonly used in the cement industry. Their high efficiency and high quality are well received by customers. In addition, they also have the following characteristics:
- Cost Saving
The clinker calcination degree of rotary kiln cement plants is high. That simplifies the follow-up process, improves the product qualification rate, and realizes the purpose of cost-saving. Besides, due to the effective utilization of heat energy, its fuel consumption is relatively low and the production cost is well under control.
- High Energy Utilization
The rotary kiln cement plant has a wide range of energy utilization, which can make full use of cheap energy, clean energy, and even the gas that has pollution to the environment.
- High Production Efficiency & Large Output
Rotary kiln cement plants can realize large-scale and continuous cement production with high output and high production efficiency. They apply the most advanced production technology with a simple process. The cement product quality can stand the test.
Supporting Equipment For Rotary Kiln Cement Plant
In addition to the main calcining equipment cement rotary kiln, the rotary kiln cement plant also needs some other highly mechanized ancillary equipment, such as:
Cement crusher: cement raw materials vary in size. Before be calcined in the cement rotary kiln, they should be processed by cement crushers to reach certain fineness. The frequently used cement crushers include cone crusher, hammer crusher, impact crusher, jaw crusher, etc.
Cement mill: cement clinker is a kind of gray-brown spherical particle with a large size. They need to be ground into cement powder by a cement mill before packed in the bag. The cement ball mill, cement vertical mill, and cement roller press are all good choices.
Clinker cooler: this equipment is usually set behind the cement rotary kiln, mainly responsible for cooling down the hot cement clinker as soon as they discharged from the kiln.
Cement dryer: the rotary kiln dryer is used to dry the water in the raw material.
Tips For Purchasing A Rotary Kiln Cement Plant
Choose A Reliable Manufacturer
The first thing we have to do before purchasing a rotary kiln cement plant is to find some big brand cement equipment manufacturers. Because these manufacturers have large economic strength and scale and are trustworthy in terms of equipment technology and production capacity, they can escort the quality of equipment. After that, we need to carry out further comparison and investigation on them.
- Big technology investment
Large scale cement equipment is directly related to the cement production and future income of the cement plant. The manufacturer that invests big in equipment technology appears to have more advantages.
- Stable quality system certification
The life cycle of high-quality equipment is longer, which is conducive to saving investment costs. The quality system of mechanical equipment in each country has certain regulations on the equipment material and tracking quality. Companies with stable quality system certification are worthy of our cooperation.
- Comprehensive service
Whether the manufacturer has perfect service is an important consideration factor, such as the equipment customization, installation, debugging, and specific operation training services, as well as spare parts supply and other after-sales services. All of these services will save us a lot of trouble.
- Factory field visit
The field visit to cement equipment manufacturing factory can help us intuitively inspect the equipment quality. At the same time, direct and effective communication is more conducive to the cooperation of both sides. Therefore, whether the manufacturer offers the factory field visit service is important.
Choose The Most Suitable Cement Equipment
The construction of cement plants is inseparable from the cement equipment which occupies the biggest investment. How to choose the most suitable cement equipment?
- Equipment quality
Quality can measure the service life of the equipment. The equipment with good quality will have a longer service life. We can start from the hardware configuration of the equipment, comparing the casing material, motor, engine power, power consumption, energy consumption, rotating speed, and a series of other parameters.
- Cost performance
The price of cement equipment is the concern of every buyer. It can reflect the quality of equipment to some extent, but it is not that the higher the price, the better. We still need to comprehensively consider the cost performance of the equipment.
- Equipment model
The selection of cement equipment models will affect the output of cement plant and cement product quality. We should select it to combine with the specific investment and cement production scale.
