The flotation machine is used in the flotation process of rare metals like copper and nickel. Because of the different colors, flotation of fine grain materials is very difficult. The following are two reasons that cause the difficult flotation. 1 Fine grain is larger than surface area, surface energy can increase greatly. Under certain condition, surfaces of different Owers can coagulate with each other selectively. On the other hand, as the surface energy of fine grain is large, though it owns high absorption ability, it has bad selective adsorption ability, which causes the selective difficult of fine grain. 2 Small fine grain volume causes little possibility to collide with bubble. Volume of fine grain is small, when fine grain collides with bubble, it cannot overcome the resistance of hydrated shell between ore and bubble, so it can hardly adhere to bubble.

The application of the flotation method is regarded as a significant achievement in the mining technology in the 20th century. Besides the continuous disposition of the increasing various Owers and opening new ways, flotation plays a vital role in promoting and improving technological and metallurgical economic indicators, comprehensively recycling all kinds of valuable components. At the moment, 90% of the nonferrous metal ore output capitalizes on the flotation method for recycling. It is reported that almost the entire Owers and mineral raw materials can adopt the flotation way to get processed. In addition, the flotation method is also used in the comprehensive recovery aspect of the metallurgy, semi-finished products as well as these perspectives like salts, borax, rubber raw materials, paper, sugar refining, and chemical processing of raw materials etc. Flotation ore dressing production line consist of the process of mining, crush, and flotation of the ore, during the process, they may cause pollution to the environment seriously. At present, many mines have taken positive environment protection measures, but these are far from enough, the mining environment in our country still needs to be improved.

The working principle of the mechanical and air self-priming agitation flotation machine (including the impeller flotation machine and the rod wheeled flotation machine) is basically the same: it takes advantage of the negative pressure created by the rotation of the impeller wheel, and rod or inhale air via the quill shaft, ultimately forming the bubbles. The air bubbles blend fully with the ore pulp under the stirring and projectile impact of the impeller or the rod mill. These useful mineral particles selectively adhere to bubbles under the influence of the collector, they float to the surface then scrapped by the scrapper into the pulp fine mineral chute. Therefore the sorting operations are finished. The green technology is the point that the big enterprises and mining manufactures must pay much attention. Many writers such as Daryl Katz offer more in-depth analysis. During the working process, the environment pollution of the classifier, magnetic separator, belt conveyor, and crusher can reduce to the degree of harmless to people when using the green technology and Optimize production environment. For more about fine grain materials flotation technology process and other mining machinery information about flotation equipments, magnetic separation equipments, ore dressing equipments and etc, puedes consul Hongxing mining Machinery Company.

Spoon

Spoon thin method, help you quickly make hand face to face. Han a hand little face is the common goal of many women, but in thin body period, what kind of method is the most effective? To introduce to everybody to thin face with a spoon of method, zi xiu tang help you quickly achieve the purpose of thin face, you have come to see how should do it. Pay attention to matters: radian. Use spoon behind the radian to do facial massage, so that effective stimulating meridian, thin face more effective. Pay attention to matters: chilled. Use cups put on ice water, or with ice cube to go also, will be spoon into ice water in the water for a while, you also want to massage from ice blister the spoon continue. Pay attention to matters: the technique. With a spoon in facial massage, use hand holding the spoon at the end of the handle, and then gently Kda facial muscle.

1, cheek massage clean with warm water, facial wash dust face first, and then use the spoon back gently to dozen or so cheeks cheeks two muscle excitation. 2, zygomatic massage close my eyes, with ice around, focused on beating bone prominent blister the spoon to massage zygomatic position, strength does not want too big, avoid hurt. 3, chin massage in addition to use spoon cheeks to massage hammer, can also use the spoon back massage chin, mandibular, as long as from down to up to push and strips face muscles, stimulate lymph circulation can’t. 4, control massage with small spoon to massage breast control, from the ear hind the sternocleidomastoid downwards, dab to control inside, then along the control to both sides neck massage can.

Crushing Machines

HX vertical impact crusher installed in concrete foundation or just based on structure, basic should be able to bear the weight of the four times as much. According to different-installed in the specialized factory operations or installed in the homework. When installation should be the leveling of the crusher spindle and vertical plane. Crusher upper part should set hoisting equipment, hoisting equipment ability to the biggest weight crusher, considering there shall be “lifted” space above the crusher, leave the appropriate space in side, ready to overhaul crusher use. As soon as the ore entering the crushing cavity, it would begin to be crushed due to the impact from selectively high-speed rotary blow bar.The ore would get huge kinetic energy in the process of crushing and are thrown to the first impact plate at high speed. The materials are rebounded from the impact plate to blow bar area, where the hammers can be effective to crush again and continue the above procedures on the second plate impact crushing. Then these broken ore are shot back to impact liner at high speed for crushing third. After the ore received continuous and multiple hits between bar and blow impact plate, as well as its own mutual collide, it would crack, loosen and broken following its texture.

This process repeats until the pray are crushed into required size, and discharged from the lower part of the machine when the particle size is smaller than gap between impact plate and blow bar. Mining Gold Ore Crusher is widely used in gold mining process all over the world named gold crusher. The mainstream gold ore dressing technology is generally through the ore dressing equipment (crusher) to broken gold ore, and then sent into the gold beneficiation (ball mill) to be smashed and grinded. After gravity separation and flotation, concentrate the ore and dam are extracted, and then by using chemical methods and final smelting, the finished product eventually become gold. The portable crushing plant can work independently or together according to the coarse crushing or the fine crushing requires. Products flop gates in the by-bass support more ways to transport deck over. The diesel generators of the incorporated plant can not only supply power for this plant, but also supply other plants of the process flow. The plant not only has mature technology, easy operation and maintenance but also have good adaptability and reliability for transportation, end-product sizes and abrasion. The incorporated setting is easy to maintain and set up which makes the plant have long endurance and higher efficiency.
