Automatic adjustment rod mill feeding set value control

The above grinding process is the setting and ratio control performed under the condition that the ore properties and the grinding media are constant. In fact, due to the hardness or particle size of the ore, or due to the reduction of the grinding medium, the qualified particle size of the overflow of the flow device will be reduced, and even the grinding machine will be overloaded; otherwise, the ore size will be reduced and the hardness of the ore will be reduced. In the case of softening, the processing capacity of the mill cannot be fully utilized. To this end, the change of the ore content of the ore is used to compensate for the influence of changes in the hardness and grain size of the ore. On the basis of the fixed value control, the control of adjusting the set value of the ore is introduced. The control principle is shown in the figure.

Figure Rod Mill - Cyclone Control System Block Diagram
According to the flow rate and concentration of the slurry supplied to the ore by the cyclone, the system calculates the total parameter P9 of the reaction rod grinding and gravel grinding according to the following formula:
P 9 =K 1 +K 2 F 7 (1+D 6 )+K 3 D 6 (1)
Test F 7 - slurry flow, m3 / h;
D 6 - pulp concentration, g / cm3.
K 1 (10.0), K 2 (0.1), K 3 (1.0) - coefficient.
When the ore is easy to grind, the content of -200 mesh particle size in the overflow slurry of the cyclone increases, and the particle size control loop reduces the water addition amount of the sand pump pool to ensure the particle size constant, the pulp concentration is correspondingly increased, and the cyclic load is reduced. At this time, the calculated value of P 9 is also small. The deviation value between the set value of P 9 and the setting controller (9) is positive. After the controller (9) calculates, the set value of the output of the output is increased, which increases the processing amount of the rod grinding surface. Conversely, when the ore is changed or the ore size is coarsened, the control system automatically reduces the amount of ore feeding on the rod grinding surface in order to ensure the granularity of the grinding product without overloading and overflowing the circuit.
Adjusting the set value of the ore control is more stable than the set value of the swirler of the mine control, but the ore supply has some fluctuations, and it has higher processing capacity under the condition of ensuring the product size.

LED Car Light


LED car lights refer to the use of LED technology inside and outside the car for external and internal lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load testing. LED car lights can be widely used to create the environment in the car. The life span is 50,000 hours. The structure of the LED is sturdy and not easily affected by vibration. The light output brightness will not significantly decrease during use. LED car lights are suitable for various lighting applications of automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signal lights, daytime running lights, pedal lights, instrument lights, license plates Lights, door lights, interior lights, width indicator lights, navigation, entertainment systems, backlights and indicator lights, etc.


  • Advantage

1. Energy saving: Light-emitting diodes are directly converted from electrical energy to light energy. Compared with ordinary car bulbs, the power consumption is only 1/10 of that of traditional lamps, which can better save fuel consumption and protect car circuits from being burned by excessive load currents. Bad.
2. Environmental protection: There are no ultraviolet and infrared rays in the spectrum, low heat generation, no radiation, low glare, and the waste can be recycled, no pollution, no mercury, and safe touch. It is a typical green lighting light LED source.
3. Long lifespan: There is no loose part in the lamp body, and there are no shortcomings such as easy burning, thermal deposition and light decay of the filament. Under the appropriate current and voltage, the service life can reach 80,000 to 100,000 hours, which is longer than that of traditional light sources. More than 10 times longer. (It has the characteristics of one-time replacement and lifetime use)
4. High brightness and high temperature resistance. (Electric energy is directly converted into light energy, and the heat is small, and it can be touched by hand, which is safe and secure)
5. Small size. The designer can change the lamp mode at will to make the car diversified. Automobile manufacturers' favor of LEDs is entirely determined by the advantages of LEDs themselves.
6. Good stability, strong anti-vibration performance of LED: resin encapsulation, not easy to break, easy to store and transport.
Seven, the luminous purity is high, the color is clear and bright, no lampshade is needed to filter the light, and the light wave error is within 10 nanometers.
8. The response speed is fast, no hot start time is needed, and it can emit light within microseconds. The traditional glass bulb bulb has a 0.3 second delay, which can prevent rear-end collision and ensure driving safety.
