Introduction to dosing methods of flotation automatic dosing machine

Different drugs need to be used in the flotation and mineral processing process. With the development of science and technology, the increase of drugs has been automated. The flotation dosing machine is the equipment for automated dosing. How to correctly handle different flotation drugs? Are you clear about the increase? Come and get to know it quickly:

The flotation dosing machine is equipped to dilute solid drugs into liquid form for added convenience. Drugs with poor water solubility, such as xanthate, amine black drug, sodium silicate, sodium carbonate, copper sulfate, sodium sulfide, etc., are all prepared into aqueous solutions for addition. Configure concentration values ​​ranging from 2 to 10 percentages. Drugs that are insoluble in water must be dissolved in a solvent first, and then added into an aqueous solution, such as amine collectors. Some can be added at the same time, such as 2 oil and No. 31 black drug. , oleic acid, etc. For drugs that are easily soluble in water and have a large dosage, the concentration value is usually 10-20%. For example, sodium sulfide is used at a concentration of 15%. For drugs that are difficult to dissolve in water, organic The solution is dissolved and then prepared into a low concentration aqueous solution.

For different ores, due to different characteristics, the fluctuation range of the drug dosage of the flotation automatic dosing machine is also large. Even if they belong to different types of ores, there are differences due to the conditions where the ore deposits are generated, and the effective minerals and veins are different. The composition of stone is different, and the dosage of drug usage is also different. The general range is: the dosage of collector is 20-1500g\/t. Under normal circumstances, the dosage of xanthate collector is less, about 100g\/t per day. The amount of t mine used is from tens to more than 100 grams. The amount of fatty acid collector is relatively large, ranging from several hundred grams to more than one kilogram per ton of ore. The amount of foaming agent used is 20-2000g\/t. Activator The usage amount is 200-1000g\/t. The usage amount of inhibitor is 100-200g\/t. The usage amount of medium regulator is 500-3000g\/t. When sorting specific ores, a narrow usage area should be selected according to the experimental conclusion. Specific application As long as the material composition of the ore remains consistent, the dosage of the drug should not be changed at will.

The flotation automatic dosing machine adopts microcomputer adjustment, which has a dosing accuracy of more than 1 mL. It can accurately adjust the dosage of the drug and obtain the best drug dosage system.
