Vertical Ore Milling Equipment Main Control Parameters I
Vertical Ore Milling Equipment has been started in a large number of cement factories and other enterprises put into operation, for vertical Ore Milling Equipment such a set grinding, drying, air delivery and material grading as one of the large complex equipment, the correct and high level of installation, commissioning and production operation Operation is an important guarantee for its stable and efficient operation. This article focuses on the actual operation of LUM Ore Milling Equipment in the hot stove heating conditions and the main reasons for the emergence of various problems and adjustment methods, especially the initial stage of debugging, many companies are not paying special attention, often difficult Resulting in not running smoothly, this article can play a guiding significance.
Vertical Ore Milling Equipment work, the main motor current is rated current of 80% to 90%, the material thickness of 70 ~ 80 mm, the separator speed of 50 r/min or so, the temperature of 85 ~ 95 ℃ out of the Ore Milling Equipment, the grinding temperature < 300 ℃, vertical pressure difference 6000 ~ 7000 Pa, production capacity of 430 ~ 480 t/h, the vibration value of 6 ~ 8 mm/s, loading system hydraulic pressure 8 ~ 9 MPa. The main parameters through the following aspects of regulation and control.
Vertical Ore Milling Equipment feed volume. Under normal operation, under the precondition of ensuring the granularity of product, the output of vertical Ore Milling Equipment can be properly increased, and the parameters of various aspects must be increased. The adjustment range can be adjusted according to the vibration value, outlet temperature, system air volume, inlet and outlet grinding pressure difference, main motor current Factors to decide. The general situation is to increase the amount of material feeding, thickened material layer, increased roll pressure, increased ventilation, if the output increased significantly, the Ore Milling Equipment will also slightly increase the pressure difference. It should be noted that the main motor current to be within the rated range, the vibration value to be within the limits. Conversely, if you want to run in a low yield state, then the material layer is easy to thin, but also easily lead to vibration. So basically it should be in a stable feed volume and the amount of external circulation operation. If it is to put the sieve Yu to raise production, the direct method is to reduce the speed of the separator, improve the system air volume.
In and out of grinding pressure difference. Vertical Ore Milling Equipment operation is the emphasis of stability and balance, out of Ore Milling Equipment normalized pressure should be 6000 ~ 7000Pa, which directly reflects the vertical Ore Milling Equipment work load and Ore Milling Equipment cycle status. Pressure changes mainly depend on the vertical Ore Milling Equipment feed volume, ventilation, outlet temperature, there are other special factors, such as grinding oil spills. If there is a big change in the pressure difference, you should first check the dosing station is expected to stabilize the material, such as feeding normal, can be adjusted by vertical Ore Milling Equipment feed, ventilation, separator speed and water spray to adjust, if still not, should Other cases to judge.
