Disc horizontal, vertical roller mill, powder area is a plane, the center of gravity of the roller system to the disc, only the movement in the vertical direction, all the impact and pressure are easy to handle in the vertical roller mill direction. Three-roll mill roll suspension systems integration and other forms of mass compared with the small, low inertia. The required power is small, the advantage of smooth motion, the inner end of the shaft 3 is rigidly connected to the roll, but the outer end of the shaft is connected to the hydraulic cylinders, respectively, a movement of the roller relative to the other two rollers have little effect, only 2%. Substantially vertical movement of the rollers independently of each other. Between the roller axis and the disc diameter roller bearing an angle so that only the circumferential direction by force, without axial thrust, vibration, bearing load and conducive to life. Before starting the use of two-way hydraulic cylinder roller can be jacked up, no-load start, no auxiliary transmission device, the material to be fed to a certain thickness of material to touch the hydraulic cylinder when the pressure roller in the other direction, and gradually work into powder, start simple and smooth mill. When running with the metallic foreign body, roller will lift automatically, protective equipment. Horizontal disc and the cylindrical center of gravity of the roller mill is only vertical roller mill movement of the roller set, and the impact of all the dynamic reacting force in the vertical direction only. Compared to other roller grinding mill with rolls of small mass, inertia, and dynamic forces and vibration is very small, the mill rolls have been patented. Increase the bearing roller inside, it can withstand greater radial load. Grinding roller and disc liner chosen a better wear-resistant materials, no dangerous cracks. Adjustable roller liner to use, so its high utilization. Compared with other roll mill, the mill roll length liner life. Changes in the larger roller layers of material into the liner wear unevenly and foreign matter have good adaptability. The large size allows the feed, pre-broken to reduce the requirements. Easy to adjust the air inlet, a small footprint, low construction costs.

With the rapid development of our national industry, and the prospect of rotary kiln is becoming brighter in the future. The human beings nearly dont talk about the issues about the rotary kiln in our daily life, which is the direct reason why we dont want to know about it, but there has been a long history in the developing history of our nation. There are some ways to improve the using efficiency of metal in the practical usage of rotary kiln in the reality. The early rotary kiln was just applied in the prospect of environmental protection marble crusher and grinding, but the human beings have begun to pay much more attention to the burning of the limestone with the rapid development and progress of our national scientific technology, and the rotary kiln also has the power to influence the life of human beings, which can make a big difference to the industries of cement, building material, mining and environmental protection. With the development of our national economy, the rotary kiln will have a bright future, which cannot be doubted in the developing process. At this right minute, there are so many mining manufacturers who are major in producing the rotary kilns, which is one indirect way to prove the significant position of mining machine, of course, and there must be some difference among those mining makers who own the technology with various levels and have the producing experience in this field. So we notice the mining buyer who should pay attention to the comprehensive strength and technology of mining makers when they choose some mining machines, and then they will found that Hongxing mining machinery is one best choice for them. We hope that the national mining makers can produce the advanced rotary kilns for the whole national industrial development, and we believe that the future of china industrial development will become better and better.
