In the modern cement production system, grinding system includes raw materials grinding process, cement grinding process, slag grinding process and coal powder grinding process. In general, the power consumption causing by cement process will take 60 percent or 70 percent of the whole electricity consumption.
So improving efficiency and reducing electricity consumption are the main are the key points of grinding technology research. Facing with contradiction between economic development and resources and environment, KEFID Heavy Industry carries out industrial restructuring and speeds up technological innovation. He takes the road of circular economy then develops and designs cement grinders, which adopts advanced grinding technology in the world at present.
It is that the principle of incomplete grinding and the working mode of partial external circulation. The grinding effect is high and the energy consumption is low. Unit energy consumption is reduced by more than 10% compared with common cement ball mill. The process is compact and powerful. It integrates crushing, grinding, drying, powder selection and material gas transportation together. It is easy to layout.
This kind of cement mill has been used in the raw material grinding of the new dry process cement production line with a daily output of more than 5000 tons in China. The energy saving effect is remarkable and the environmental protection advantage is obvious.
The equipments of the cement raymond mill production line are:
1. Jaw crusher, mainly used for primary crushing;
2. Bucket elevator, which lifts the material from low to high;
3. Electromagnetic vibrating feeder can send the material to the next process evenly and continuously;
4. Raymond mill, to grind the crushed materials;
5. The analysis machine sorts the ground materials.
The performance of cement raymond mill production line equipment:
1. Strong stability, low failure rate of the production line during operation and low operating cost;
2. High grinding efficiency and large output of equipment;
3. The production line has a good dust removal and sealing device, which effectively avoids the pollution of the environment by dust during the operation, and makes the production more green and environmentally friendly.
The LM series vertical mill of Kefid Machinery Co., Ltd is one advanced mill, adopting top technology of domestic and abroad, and based on many years’ mill experience. It can crush, dry, grind, and classify the materials. It can be widely used in such industries as cement, electric power, metallurgy, chemical industry, non-metallic mineral.
You can call our customer service to know the price and more details about the vertical mill.
When grinding cement, both impact action and abrasive action all take good effect. Different grinding body with different specifications can cooperate with each other to reduce the voidage and improve capacity usage ratio by increasing opportunities getting in touch with cement. When loading capacity of grinding body is certain, total surface area of small steel ball is bigger than large steel ball’s.
If you want to smash the cement, you should choose big steel ball because it will be possess of large energy. Of course, if you want to make cement finer, you should choose small steel ball. In conclusion, selecting suitable grinding body is very important for processing cement.
There will be two problems when the temperature of cement mill rises unreasonably. On the one hand, the higher temperature reaches, the greater the viscosity of cement is. On the other hand, when we grind cement, that is to say, we are grinding amixtureof clinker and gypsum which takes effects on adjusting the time that cement spend coagulating.
When temperature rises, the gypsum will lose crystal water and becomes semi-hydrated gypsum or anhydrous calcium sulfate, which changes solubility and component totally. Just because of this, settingtime of cement will be different and it will cause the cement futile due to quick coagulation. So we should control the temperature below 100°C and prohibit it rising above 120°C.
LM series vertical milling machine can be widely used in such industries as cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.
KEFID Heavy Industry cement mill helps develop cement industry
Cement industry is a traditional energy-consuming industry. Considering sustainable development, innovative research and development of grinding mill is imminent. KEFID Heavy Industry's cement superfine grinding mill is based on absorbing advanced technology at home and abroad, and it has carried out many years of innovative research and development.
The use of cement superfine grinding mill is the future direction of cement industry development. The feasibility of replacing cement ball mill with cement superfine grinding mill has been proved. KEFID Heavy Industry cement mill integrates crushing, drying, powder grinding, grading and transportation. It adopts a fully sealed system. The system operates under negative pressure. It has no dust and the process is green.
KEFID Heavy Industry has been dedicated to the exploration of cement grinding technology, hoping to make greater contributions to the cement industry. In addition to cement superfine grinding mill, our company's large Raymond mill, high-pressure grinding mill, vertical grinding mill and other grinding equipment to purify superfine or fine powder has been recognized by the majority of customers.
