Automatic dosing machine mineral processing plant talks about usage control
For mineral processing, the usage amount is very important. If there is a problem with the usage amount, it will interfere with the conclusion of the mineral processing plant. The mineral processing plantAutomatic dosing machineIt is an automatic dosing equipment to get out of trouble. There are several ways to control the flotation dose:
(1) Micro-dosing machine. The microcomputer dosing machine controls the on-off time of the solenoid valve, and can do timely and quantitative dosing for many dosing points. Please display the relevant parameters of each dosing point on the CRT screen to enhance dosing control. Basis Changes in each process parameter during dosing, and timely changes to each preset value.
(2) Based on the usage of raw ore feeding control algorithm.
This is also a simple test method. The computer converts the flow and concentration signals of the raw ore slurry into the dry ore volume of the raw ore, and calculates the required dosage based on the dry ore volume and the expected ratio, which is used as the input for the flow controller. The output value is adjusted by the controller, and then the drug is distributed to the dosing point of each flotation tank group through the distributor. It should be noted that using this test method, the drug concentration should remain stable, and the liquid in the drug storage tank should be kept stable. The pressure in the control loop of the position and drug circulation system should be maintained stable.
(3) The automatic dosing machine is based on the control algorithm usage of metals in the raw ore. The seasoning ratio can be given manually, or it can also be given according to the given relationship based on the taste of the raw ore.
(4) Control the usage amount based on the metal composition of the raw ore and the tailings grade. The characteristic of this method is that it can calibrate the tailings grade that reflects the flotation effect.
(5) Control the usage based on utilization rate and concentrate grade. The components of effective minerals in the tailings can reflect the flotation effect to a certain extent, but when the mineral properties change, it is impossible to ensure that the entire flotation process is done properly. The expected index value. Therefore, the utilization rate and concentrate grade should be further used to control the dosage. The current-carrying ray analyzer pushes the grade signals of metals in the raw ore, concentrate and tailings to the process management computer. The computer first based on the raw ore Taste and measure the new utilization rate to give a value, and then calculate the amount of collector added based on the actual utilization rate.
The emergence of automatic dosing machines in mineral processing plants has promoted more accurate dosing and improved the effectiveness of mineral processing plants, which is good news for the entire mineral processing plant field.
