Infrastructure construction is current the most important national economic construction, foundation construction vigorously, must promote the mine, building materials, cement, highways and other industries to carry out, the broken machine needs are also more and more big. First of all, in the application of the mine, the vast mining market will continue to develop the mine equipment continuously, thus increasing the market demand for the quarry crusher. Secondly, in the application of highway and railway, with highway construction planning, construction of cement and the infrastructure development inevitably stimulate crushing machine industry a new growth. Also, in the chemical and water conservancy and other aspects, the next few years will also maintain rapid growth, the demand for the quarry crusher will continue to grow rapidly. Continue to carry out the foundation of the construction will certainly promote the upgrading of the quarry crusher industry. At present, domestic quarry crusher machine industry update update frequency is higher, due to the short service life of the small crushing machine, so annual renewal of quarry crusher accounted for crushing machine needs about 20%, so there are still many quarry crusher in the overaged work. Together with the main use of mineral processing, construction and other industries of the two pieces of broken back type quarry crusher type missing, the standard is less, seriously affected the construction of road cement and other infrastructure. With the impact of foreign countries, how to improve the skills and quality of the quarry crusher, has become a major problem facing the quarry crusher industry. The replacement of the quarry crusher is inevitable, which will be a turning point for the development of quarry crusher. But it also gives us a wake-up call, the process of crushing machine, the improvement of the service life of the machine, it is extremely urgent. The increase of market demand, the upgrading of the broken equipment, has brought the opportunity to increase investment opportunities in the export market of the quarry crusher and the opportunity to diversify the investment opportunities in the enterprise. China has been a big country in the production of quarry crusher, in the next few years, due to some advantages of our products, breaking machine to enter the international market become an inevitable trend. Broken to achieve upgrading, adapt to the development trend of diversification and internationalization, we must improve the competitiveness. With the intelligent manufacturing equipment for the development of special guidelines for the implementation of "Notice of coming out, State Ministry for mechanical include security, a series of planning and looking forward to the monitoring, efficiency and other elements, fully embodies the national attention to the intelligent mechanical. Intelligent become the main development trend of quarry crusher.

1, the lack of feed When they find a lack of storage should stop feeding material, now lose out if continued risk free feed vertical roller mill, should feed vertical roller mill equipment and feed, or make the bed thinning attack rumbling sound, causing damage reducer . 2, the vertical roller mill is too large oscillations (1) feeding uneven, when the vertical roller mill mixes mostly powder, the load factor within the large vertical roller mill, resulting in thin material on the disc, and the disc with the roller directly touching, forming a vibration vertical roller mill; when the vertical roller mill when the mixture more for lump materials, formation pressure grinding roll is not stable, vibration grinding attack. The way to deal with the granularity of the grinding material is stable, appropriate adjustments grinding feed rate or reduce pressure, to ensure the required fineness of the material premise of proper lower separator speed. (2) fitting into the vertical roller mill, view the metal detector, the magnet separator is not working properly. (3) causing damage to the kiln exhaust fans or people shaking vertical roller mill kiln exhaust gas pressure is high, instability and dust concentration Ambassador vertical roller mill high temperature thereby increasing the vertical roller mill load moment should increase throttle opening of the cycle, increasing large recirculation flap into the vertical roller mill, increased vertical roller mill personnel a negative pressure, so that the vertical roller mill work balance.

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.

(1) the mill ventilation: roller mill is a kind of air swept mill, ventilation should be appropriate. Insufficient air flow, qualified raw material can not be brought out, the material layer thickness, increase the amount of slag, equipment load is high, lower yields; wind is too large, the material layer is too thin, the impact of the mill stable operation. Therefore, the vertical roller mill ventilation must match the output, not when the big, sometimes small, should remain stable. In principle, the operator selects the ventilation rate, and should be more conducive to maintaining the mill load, whichever is relatively stable, and seeks minimal vibration, slag material at least, the highest yield and best quality. In actual operation, the operator based on trends fan speed, current, pressure, volume of feed, import and export of negative pressure, temperature and other variables, to understand the operation of the mill, combined mill vibration, slag volume, product quality and other adjustments, typically by adjusting the opening of the circulation fan speed and flap in order to achieve optimum ventilation. Under normal circumstances, the entire job stability, the various trends also show a smooth, once one of these variables change, and soon it will affect changes in other variables. At this point, to make timely adjustments, otherwise the situation could stop the mill vibration may occur. Some vibration stops entirely due to negligence or lack of experience, such as: reducing material diminished when the wind, feeding time without wind, etc., may cause abnormal changes in pressure, so that the mill out of control vibration stops. (2) the material layer thickness: vertical mill, another important factor is the stable operation of the bed stability. Material layer stability, wind, air pressure and volume of feed to stabilize, or we need to maintain the material thickness by adjusting the air volume and the volume of feed. If not it will lead to timely adjust the vibration intensifies, the electrical load to stop jumping up or system problems. Theoretically, the material layer thickness should be the diameter of the roller 2% ± 20mm, the vertical mill grinding roller diameter of 3000mm, so the 60 ± 20mm is suitable material thickness. This requires the operator to pay close attention to changes in the material layer trend, try to be controlled within the optimum range, in order to ensure stable operation of the mill. In addition, raw material thickness also depends on the particle size, grindability, particle size distribution, moisture content, etc. Initial operation, in order to find the best material thickness, have debugging gauge ring height. While in the ring height gauge certain conditions, one of the important conditions for a stable material thickness is feed particle size and particle size with the management. Feeding the average particle size is too small or too fine, thin material layer; average particle size is too large or too many chunks of material when the material layer will thicken, mill load increases. Can be controlled by adjusting the amount of water spray, grinding pressure, circulating air flow and separator speed and other parameters.
