Flotation automatic dosing machine manufacturer talks about usage control

For mineral processing, the usage amount is very important. If there is a problem with the usage amount, it will affect the conclusion of the mineral processing plant. The dosing machine of the mineral processing plant is the automatic dosing equipment to get out of trouble. Control flotation. Automatic dosing machine flotation There are several ways to dose:

(1) Micro-dosing machine. The automatic dosing machine controls the on-off time of the solenoid valve, performs direct quantitative dosing on multiple dosing areas, and displays the parameters of each dosing point on the CRT screen, thereby improving dosing control. According to the dosing Changes in each process indicator during the link will immediately change each preset value.

(2) Based on the usage of computer ore feeding control algorithm.

This is a very simple control measure. The computer converts the computer slurry and flow concentration value data into the computer's dry ore volume, and calculates the required dosage based on the dry ore volume and the predetermined percentage, which is used as the input for the flow regulator. The fixed value is controlled by the controller, and then the drugs are arranged to the dosing point of each flotation tank group through the regulator. It should be noted that using this type of control measures, the drug concentration should be maintained stable, and the liquid level meter in the drug storage tank The pressure in the and drug circulation circuits should be maintained stable.

(3) According to the amount of metal material used in the flotation dosing machine computer, the seasoning ratio can be given manually, or it can be given based on the computer taste and the relationship between the given values.

(4) Control the dosage based on the computer metal composition and tailings taste. The characteristic of this method is that it can calibrate the tailings taste that reflects the effect of flotation reagents.

(5) Control the usage based on utilization rate and concentrate grade. The content of useful minerals in tailings can reflect the actual effect of flotation reagents to a large extent, but when the mineral properties change, it is impossible to guarantee that the entire process of flotation reagents will be achieved Predetermined indicators. Therefore, the utilization rate and concentrate grade should be further used to control the dosage. The current-carrying ray analyzer sends the computer, the metal material grade signal in the concentrate and tailings to the process control computer. The computer first based on the computer taste Calculate the new utilization rate given value, and then calculate the collector addition amount based on the calculated specific utilization rate.

The birth of the automatic dosing machine for flotation makes dosing more accurate and improves the actual effect of the mineral processing plant, which is a benefit to all mineral processing plant industries.
