Magnetic separator  is the necessary equipment for the separation of magnetic minerals. During magnetic separator, the ferromagnetic materials in the candidate area are suck by a magnetic system to surface of the magnetic drum. As rotating with the drum out of the magnetic area, they will be recovered into magnetic concentrate under the impact of gravity and washing water. In order to ensure the recovery rate of magnetic separator, which is inseparable from the stability and safety of the equipment,it is necessary to ensure the stable and safe production of magnetic separator.The routine inspection is a must-have thing, including daily inspection,regular maintenance, lubrication system inspection, and daily cleaning operations. 1. Daily Inspection of  Magnetic Separator  (1) Check the bolt fasteners of magnetic separator on a daily basis to see if there’s rusting. (2) Check the temperature of bearings,reducer and motor to ensure the temperature of each part is...

Although gold exists in the form of the simple substance in the natural world, gold is usually associated with other mineral ores in a complex relationship, due to the particle size and associated relationship, etc. Sometimes the conventional physical separation method has been incapable of classifying gold mine, so the separation process that uses different surface hydrophobicity of mineral becomes the common beneficiation processes in gold beneficiation plant. There are many that affect the gold flotation process , such as particle size, flotation reagent system, pulp density, flotation time, agitation intensity, inflatable volume, pulp temperature, etc., In order to achieve better flotation effect, all parameters must remain optimal value for the flotation process. 1. Particle Size In gold flotation process, the grinding fineness depends on the gold Khenpo size, too large or too small will affect the final flotation effect. Too big particle size, on the one hand, the gold might...

In copper beneficiation solutions, copper mining process equipment price is related to its type, specification, and minerals to be processed. Among these factors, the type of mineral is the key to choose the most suitable equipment. To make sure copper mining process equipment type and specification, the quality and type of copper should be studied. Taking the example of copper in Dexing, Jiangxi, it is a kind of porphyry copper deposit. And according to different mineral quality and containing properties, it is divided into two types, altered phyllite and altered granodiorite. It also can be divided into the thin vein and disseminated structure, according to various structures. There is much-oxidized ore and mixed ore in the upper and surrounding of ore. The content of copper in raw mineral is 0.5%, sulfur 2%, molybdenum 0.01%, gold 0.235g/t. The composition of ore is simple, and the mainly useful minerals are pyrite, chalcopyrite, and chalcocite. Then there are chalcocite, bornite...

It has become a consensus that the working noise is relatively large in the mineral processing plant, which not only affects the lives of people in the surrounding areas, but also causes physical and mental damage to the operators. With the continuous development of the mineral processing industry, the technology of noise reduction is more and more advanced. Today, Xinhai illustrates how to reduce noise taking   vibrating screen   the as an example. Generally, the vibrating screen is featured with the high noise level and complex sound source. So how to effectively reduce the noise of the vibrating screen? Xinhai technical expert summarizes several methods of noise reduction as follows. First, whether the loose parts of the equipment cause noise. Therefore, the first method of noise reduction is to tighten all the parts of the vibrating screen, especially the screen plate that should be replaced frequently. Next, paste with   rubber  board on the side of scr...

According to their different discharging end,   ball mills   can be divided into three types:  grid type, overflow type and peripheral discharge type. In practice, peripheral discharge ball mills are rarely used; while grid ball mills and overflow ball mills are commonly adopted. If comparing the grid types and overflow types,  what are the common grounds and differences between them? Under what circumstances are grid ball mills a better choice? And overflow ball mills?  Here, we will give a brief introduction to you. Common Grounds: Overflow ball mills and grid ball mills have basically the same structure, consisting of shells, feeding ends, discharging ends, main bearings as well as drive and lubrication system. Differences: The different structure of Feeding End. The main part of overflow ball mills’ feeding end is helical blade with the opposite rotation direction to the mills; while that of grid ball mills is grid plate. Different  Discha...

Generally, the relationship between market supply and demand is mutually reinforcing. With the continuous development of the mineral processing industry in recent years, the demand for  mineral processing equipment   for is increasing greatly. A large number of mineral processing equipment emerges at the right moment, which makes the increasing competitiveness among manufacturers. As a common grinding equipment in the ore dressing process,   ball mill  plays a key role in improving the comprehensive recovery rate of ore. In order to stand out in the market competition and gain a firm foothold on the international stage, Xinhai keeps improving and optimizing its product structure, so as to develop the perfect ball mill that can satisfy various consumers’demands. Any product, only with the high quality, can win the market and obtain the recognition of consumer. As a manufacturer with more than 20 years, Xinhai is well aware of the importance of quality, so it s...

Copper and molybdenum are accompanying minerals. Almost over 20 percent molybdenum is recovered from copper and molybdenum. Copper and molybdenum ore, which are mainly copper ore, is existed as porphyry copper with high recovery value and low grade of molybdenum (0.01~0.1%). Copper in copper and molybdenum is existed mainly as CuFeS2, Cu2S, while molybdenum is existed as MoS2. Copper and molybdenum include preferential flotation , part combined flotation and combined flotation. Preferential flotation contains two processes: one is concentrate molybdenum first, while another is concentrate copper first. There are some shortcomings of preferential flotation: copper and molybdenum is hard to reactivated, flotation process is complex, flotation index is worse, and process cost is high. Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it’s rarely adopted in industrial production. In part combined flotation process, molyb...

XCF flotation cell   is one of the important means to realize the flotation process. Since the mid-1960s, China’s flotation cell has made considerable progress for 10 years. Nowadays, with the upsizing and high-efficiency of mechanical equipment, will XCF flotation cell usher in a new wave of development? The main design of XCF air inflation flotation cell totally avoids the disadvantages of the traditional air inflation flotation cell. In the design, XCF air inflation flotation cell adopts a new cone-shaped impeller technology, which can not only circulate the slurry, disperse air, but also suck the feeding ore from the outside of the tank. Therefore, it solves the problem that the traditional flotation cell can’t suck the slurry caused by the low-pressure air. In addition, the ladder configuration of flotation operation is changed to the plane configuration, which can remove the foam pump. This design improves many problems in traditional air inflation flotation cell caus...

" The sun is parching the earth like a big fireball, and the grass near the road is almost burning. The searing air makes people hard to take a breath. Without a breeze, the cannas along the road almost withers." A child described the summer of 2018 in an essay. However, a group of Xinhai people is still striving for completing each project delivery as scheduled in the scorching sun. Let’s see the latest news about Xinhai mineral processing   EPC   projects!
