Jiangsu Pengfei Group High-efficiency Energy-saving Grinding Equipment

Grinding system is a key link in cement, metallurgy, chemical industry and other industries, and its equipment level directly affects the production efficiency and energy consumption index. Pengfei Group has been deeply engaged in the R & D and manufacturing of grinding equipment for more than 40 years, and the manufacturing scale of grinding equipment ranks second in the world. The products cover the four core main machines of Vertical Roller Mill, Tube Mill, Roller Press and Separator, and are equipped with complete automatic complete systems for drying, powder selection, conveying and dust collection. Cement raw meal, Pengfei grinding equipment insists on Energy-saving, Intelligent and Integrated R & D routes can not only supply independently, but also support the overall output of the group's cement and lime EPC projects, and the products are widely used in more than 50 countries along the "the Belt and Road" in various provinces and cities in China. It is suitable for many fields such as Building materials, Metallurgy, Electric power, Chemical industry and Solid waste recycling. With the comprehensive advantages of low energy consumption, high stability and long service life, it has become the mainstream brand in the global grinding market.

separator is responsible for precisely regulating the fineness of the finished product;"; The hydraulic system provides continuous grinding pressure; the grinding disc and the wear-resistant surfacing grinding roller complete the material rolling; the hot air channel integrates the drying function.

2. The material layer is compacted by the high-pressure grinding roller to complete the double crushing of extrusion and shearing, and the hot air introduced synchronously dries the high-moisture material in real time. The crushed fine powder is carried to the top powder concentrator by the ascending airflow, the qualified fine powder is sent out and collected along with the airflow, the coarse particles automatically fall back to the grinding disc for secondary grinding, and the whole process is closed-loop circulation operation.

3.

For the 6 × 6000TPD cement production line project in Egypt, Pengfei provided six Φ5.0X74m rotary kilns, two PFRM63.6 vertical mills for raw materials and two PFRM56.1 vertical mills for raw materials

. It can be matched with external elevator and powder concentrator to form a circular flow grinding system.

2. in that circular flow system, the ground material is sent to a pow concentrator through an elevator, the fine powder finis product is separated and put into storage, and the coarse material is refluxed and ground again.

3.

Two Φ5.2 × 110m roasting kilns, two Φ5.5x58m acidizing kilns, two Φ4.5x55m cooling kilns, Two Φ3.1

hydraulic systems provide 100 ~ 150MPa high pressure for the movable roll, and the roll surface adopts tungsten carbide wear-resistant pattern layer.

2. A large number of micro-cracks are produced by the mutual extrusion of material particles, 20% -30% of the qualified fine powder is directly produced, and the rest forms a dense material cake full of cracks. The material cake is sent to a ball mill or a powder concentrator for secondary processing after being broken up, and the grindability of the material is improved by more than one time.

3.

1. The core grading rotor adopts streamlined structure and is equipped with adjustable guide vanes to precisely control the grading airflow.

2. that variable frequency rotor form a stable forced vortex, and the material is classify under the dual action of centrifugal force and air flow buoyancy. The qualified fine powder passes through the rotor blade and is collected as a finished product, and the coarse particles are thrown to the inner wall of the shell for reflow and re-grinding.
