In order to better ensure faster performance of drugs, reasonable selection should be based on the characteristics of iron ore, drugs and processes.Peristaltic pump dosing machineDetailed address and method of administration.
(1) Dosing location. The selection of the dosage location is related to the use and characteristics of the drug. Usually, the pH regulator is put in first, and can be added to the ball mill equipment. It can make the decelerator and flotation agent at a suitable pH value. It can make full use of its effect in coal slime water and can dissolve many "inevitable ions" that are harmful to flotation agents. The polymerization inhibitor should be added before the flotation agent, and is usually also added in the ball mill equipment, so that it can be combined with the flotation agent as soon as possible. The contained minerals produce a fresh surface. Active agents are often added to the mixing tank, where they are mixed with the slurry for a while to promote and activate the mineral effect. Flotation agents and flotation agents are added to the mixing tank or flotation machine. Foaming agent, but insoluble flotation agent is often added to the crusher in order to better promote its dispersion and increase the potency time with the ore.
Usually the order of addition depends on the situation: ① When flotation reagents are used as raw ore: pH regulator-retardant-flotation agent-frothing agent. ②Inhibitor flotation minerals: active agent-flotation agent-frothing agent.
(2) Dosing method of peristaltic pump dosing machine. There are usually two forms of dosing, one is added once, and the other is added in several times. One-time dosing is concentrated by the drug, and it is added once before sweeping. Full of oil. The added medicine has a high concentration and is convenient. It is generally easily soluble in water and cannot be carried away by plastic foam. It is not easy to be reflected in the slurry and invalid medicines, such as quicklime powder, soda, etc., are generally It is added at one time. The amount of addition is divided into several times, and it is added in several times along the steps of initial processing, cleaning, and cleaning. Generally, 60% to 70% of the total output value is added before the flotation agent, and the rest is divided into several times. Add to the appropriate address. For the following situations, add them in stages: ① Drugs that are easily oxidized, easily dissolved, and prone to qualitative changes, such as xanthate, SO2 gas, etc.; ② Insoluble in water, easily dissolved by plastics Drugs brought by the foam, such as oleic acid and fatty amine flotation agents; ③ Drugs with strict dosage regulations, such as sodium sulfide. If too much is used in some cases, reactions are likely to occur.
According to the above regulations, the usage location and dosage of the peristaltic pump dosing machine design cannot be changed at will during the manufacturing process. As we all know, in the field of flotation chemicals for a long time, if the flotation machine" In emergencies such as "sinking", concentrated mining of poor quality or large quantities of metal items, certain drugs can be temporarily added in appropriate places according to the actual situation to reduce losses as soon as possible. However, abnormalities must be found immediately Therefore, make adjustments as soon as possible to change the manufacturing situation into normal life.
