We all know the actual operation of the flotation automatic dosing machine, but do you know the specific standards? Let’s learn from the editor now.
1. The flotation machine stirs and mixes the slurry. The purpose of stirring is to suspend the mineral particles so that the mineral particles and bubbles can achieve reasonable contact. The purpose of mixing the slurry is to make the agent uniform after adding the medicine and before adding the air. Disperse and interact with mineral particles. The addition of aqueous solution pharmaceuticals can be done with a pipette, measuring cylinder, measuring cup, etc.
2. The flotation dosing machine scrapes the foam. Observe the size, color, thickness and other surface conditions of the foam according to the flotation process. By adjusting the amount of foaming agent used, the amount of aeration, the level of the slurry and strict operation, it can be controlled The quality and amount of foam scraped out. The aeration amount is adjusted by opening the control valve to the size of the flotation machine speed ratio. After the aeration amount is confirmed, it should be fixed to avoid comparability of the test. The liquid level of the flotation machine automatically controls the foam layer. The thickness is generally 25-50mm. The slurry cannot overflow from the flotation tank on its own. The foam adhering to the wall of the flotation tank must be washed into the tank frequently. When starting and ending the foam scraping, the pH value of the slurry must be measured and recorded. and temperature. After flotation is completed, pour out the tailings and clean the flotation machine.
3. Flotation machine grinding. First clean the ball mill by running it idling for a few minutes, then add part of the water required for grinding, then pour in the ore sample and the chemicals that should be added to the grinding, and then add the remaining water Add. When grinding, pay attention to whether there is any problem with the speed ratio of the ball mill and whether there is any problem with the sound to determine whether the ball or rod is moving normally in the mill. The grinding time must be correctly controlled.
4. Flotation automatic dosing machine fine powder processing. The products of the flotation machine should be dehydrated, dried, weighed, and sampled for chemical analysis. If it is very fine or contains a large amount of mud, coagulant can be added to speed up the settlement. When drying sulfide ore, the temperature should not exceed 110 degrees Celsius to prevent oxidation and changes in product quality grade.
