Background
Lime milk is commonly used as a medicament in ore dressing plants, for example, reverse flotation of iron ore commonly uses lime milk as an activator of iron minerals; often, lime milk is added to the transported pulp during long distance pipeline transportation of the concentrate or tailings to form a calcium carbonate scale layer on the inner wall of the pipeline to protect the pipeline from pulp abrasion. At present, most of lime milk selected in factories is prepared by conveying bagged calcium oxide to a medicament preparation workshop through an automobile for stockpiling, manually conveying the bagged calcium oxide to a lime milk preparation stirring tank, scratching a packaging bag by a knife, discharging the calcium oxide into the stirring tank, stirring and mixing the calcium oxide with water to prepare lime milk (calcium hydroxide aqueous solution). The mode can generate a large amount of calcium oxide dust in various procedures of calcium oxide stacking, carrying, bag breaking and unloading, so that the environment pollution is caused, and the strongly alkaline calcium oxide and hydrate thereof not only can cause serious pneumoconiosis, but also can cause strong alkali damage to the respiratory system of people. According to the preparation method, the calcium oxide is directly added into the stirring tank, and the temperature of a workshop is often too high and the dust pollution in the workshop is serious due to the fact that the calcium oxide releases heat when meeting water in a large amount. In addition, part of lime particles are usually agglomerated after being digested on the surface of water, so that the lime is not completely digested and subsequent feeding facilities are blocked. Finally, most of the modes depend on manual operation, metering is inaccurate, the concentration of the lime emulsion is difficult to control accurately, and manual operation has high labor cost. In addition, the bag breaking is carried out by the bag breaking machine, and the feeding mode of feeding is carried out by the chain plate type conveyor, so that dust during bag breaking is avoided, but the conveying efficiency of the chain plate type conveyor is low, the lower part of a chain plate is easy to be blocked, and the failure rate of the chain plate type structure is high. Therefore, a preparation system of lime milk medicament for mineral separation, which has the advantages of simple process, high automation degree, no need of manual operation, good preparation effect of lime milk, stable system, low failure rate and no environmental pollution and personal injury, is needed to be developed.
