To Recur to the Size of the Solid Particles

The classifier.html">spiral classifier recurs to the principle that solid particles of different sizes have different specific gravity, and thus, the settling velocity in the liquid is different, the fine mineral particles floating in the water overflow, the coarse ore particles sink to the bottom. It can be able to filter the powder in the mill and then the crude material is screwed into the feed inlet by using a spiral piece, to filter out the fine material that will be discharged from the overflow tube. The grading machine base is made of the channel, the body is made of welded steel plate.
Grading machine has simple structure; it is reliable, and easy to operate. Grading machine is widely applicable in the concentrator to form the closed circuits process with ball mills to sort the shunt mineral sands, or it is used for the grading of ore and fine mud in the gravity concentrator as well as the pulp particle size classification in the metal beneficiation process and the desliming dehydration and other operations. Grading machine structure is simple, reliable, and easy to operate. The head and the shaft head of the spiral shaft are made of the pig iron sets, it is wear-resistant and durable, and the lifting device includes the types of electric and manual. Bubble mineralization. The ore particles are selectively adhered to the air bubbles, which is the basic behavior in the flotation process. With regard to the pulp adjustment and the addition of the flotation reagent, its purpose is to cause the difference of the nature of the mineral surface, i.e. to change the wettability of the mineral surfaces, to adjust the selectivity of the mineral surfaces so that some of the mineral particles can be attached to the gas saturation, while others cannot be attached to the bubble. As for the problem of agitation to result in a large number of bubbles, it can be realized by the stirring action of inflatable flotation machine, resulting in the dispersion of the pulp in the air and the formation of a large number of bubbles, or to promote the air that has been dissolved in the pulp to form micro-saturated precipitation.
