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...

The magnetic separation process is achieved by the effect of magnetic force and mechanical force on ore particles in the magnetic field of magnetic separator. The particles with different magnetic move along different tracks, and thus two or several individual mineral processing products are separated. According to the dry and wet degree of minerals, the types of magnetic separator can be divided into dry magnetic separator and wet magnetic separator . So, how should we choose the right type of magnetic separator? 1. Application of types of magnetic separator Wet magnetic separator is suitable for the coarse separation of lean iron ore after coarse or medium crushing, raw ore separation that has not been fully restored in the closed-circuit roasting operation of hematite reduction, iron removal from petuntse in the ceramic industry, as well as other iron removals in foundry sand, refractory materials and other industries. Besides, wet magnetic separator is suitable for those areas...

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...

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: 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  Dischargin...

Ball mill and rod mill are used widely in plant and are compared by us. This text will analyze the two equipment in some aspect. The grinding theory. Though used different medium (steel ball and steel rod are contained in a ball mill and rod mill), the working theory of ball mill and rod mill are similar. When the shell moves, the medium in the shell is raised and down which has an impact on ore. Some medium may close to the tube wall of the shell which can grind the ore. After a long time grinding, the material is ground to the correct size. For details, the grinding theory of ball mill and rod are different in many ways. For the ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it needs a high rotate speed and has a higher power consumption. But for rod mill, the grinding effect is better which need a lower rotating speed and has a...

Now, heap leaching is a popular way to separate gold from ore. Gravity, flotation, amalgamation, cyaniding, resin in pulp, carbon plasma adsorption and dump leaching are commonly used in gold processing. When gold ore is covered by sulfide ore, it is hard for cyanide to react with gold ore within. Microbe could be used to dissolve sulfide cover for the following heap leaching stage. We will introduce the microbe mining processing method in this article. Moderate thermophile and thermophilic bacteria are the most commonly used microbes in leaching, such as Sulfur thermophilic bacillus, thermal oxide vulcanization coli, sulphur bacteria and thiobacillus ferrous oxide. These microbes obtain the energy they need in the metabolic process according to oxide sulfide ore. There are three types of microbe leaching: contact leaching mechanism, indirect leaching mechanism and collaboration leaching mechanism. Contact leaching mechanism: bacteria secrete EPS to absorb on the ore surface. In the...

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!
