Inlet Temperature Impact On The Vertical Ore Milling Equipment Operation

Vertical Ore Milling Equipment inlet temperature, will cause the Ore Milling Equipment material to dry too fast, suspended material increases, the differential pressure increases, the material bed is thin and unstable. At this point should be appropriate to increase the amount of water spray, stabilizing the material layer, or appropriate to increase the amount of feed. If you are not working, then adjust the humidifier water spray to reduce the outlet temperature; vertical Ore Milling Equipment inlet temperature is low, will increase the main motor drive power, thickening material layer, the output becomes low. At this point should reduce the amount of water spray to increase the inlet temperature, appropriate to reduce the amount of feeding.

Outlet Temperature Impact On The Vertical Ore Milling Equipment Operation

Vertical Ore Milling Equipment outlet temperature is the basis of our judgment of the state of the vertical Ore Milling Equipment grinding, we can judge whether the operation adjustment method we adopted is reasonable according to the outlet temperature of the Ore Milling Equipment and other trends.

  • Vertical grinding outlet temperature is too high when the grinding conditions: material thinning, material instability, Ore Milling Equipment power fluctuations, vibration; increase the amount of material back; product fineness coarse.
  • Ore Milling Equipment outlet temperature is too low when the grinding conditions: material layer thickness; Ore Milling Equipment power is high; grinding move large; Ore Milling Equipment output decline.
  • Ore Milling Equipment outlet temperature changes and vertical Ore Milling Equipment cycle load relationship: the system air volume, the same speed separator, the cyclic load changes reflect the changes in material properties and Ore Milling Equipment grinding efficiency.

  • A. Cycle load increases, the outlet temperature drops. When the cyclic loading rate becomes larger, the average fineness of the material in the Ore Milling Equipment becomes smaller, so that the heat transfer area increases, while increasing the amount of grinding memory will increase the heat transfer area, so that heat transfer between the airflow and the material is accelerated, resulting in Ore Milling Equipment outlet temperature dropped.
  • B. The cycle load decreases and the outlet temperature rises. At this point the Ore Milling Equipment has a higher grinding efficiency.
  • C. Affect the Ore Milling Equipment cycle load factor: the greater the air volume, the cycle load rate is small; the faster the separator speed, the higher the cycle load rate; material grindability, material thickness also affect the cycle load factor. In normal production, by setting a reasonable inlet air temperature and water spray to form a suitable layer. This will help improve the grinding efficiency and reduce the cycle load rate.

The Relationship Between The Optimum Grinding Condition And The Temperature Of The Ore Milling Equipment

In the vertical Ore Milling Equipment operation, sometimes the Ore Milling Equipment temperature control at 92 ℃, the Ore Milling Equipment has the best grinding conditions, and sometimes need to be out of the Ore Milling Equipment temperature control at 98 ℃ Caixing. Because of the moisture, particle size and other physical properties of raw materials and the ratio of raw materials are different, resulting in the formation of a stable, reasonable layer of water required for different. Therefore, in the operation, the temperature should not be out of the Ore Milling Equipment as a control target, but should be the grinding status of the Ore Milling Equipment as a control target, focusing on the changing trend of the Ore Milling Equipment temperature, but not too much emphasis on the size of the temperature value.

According To The Changes In Temperature Out Of Reasonable Adjustment Of Other Parameters

  • A. Grind the initial adjustment. In the initial stage of Ore Milling Equipment opening, as the fineness of the material in the Ore Milling Equipment decreases, the outlet temperature of the Ore Milling Equipment gradually decreases. When the outlet temperature stops rising and falls, it indicates that the amount of material inside and outside the Ore Milling Equipment is reduced and the feed amount can be gradually increased.
  • B. Normal grinding in the adjustment. As the Ore Milling Equipment temperature on the amount of material in the Ore Milling Equipment reaction is very timely, stable grinding Ore Milling Equipment for a period of time, if the exit temperature continues to decline, we can initially determine the grinding memory material too much; when the separator current declines, bucket Mention, the pump current drops, the Ore Milling Equipment power increases, material thickening, this time can confirm the Ore Milling Equipment material is indeed too much, the feed can be reduced to the right place. As export spies start to rise and Ore Milling Equipment power decreases, feed volumes can be gradually increased.
