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...

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...

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...

Due to various reasons such as equipment structure, we cannot crush the material to the required fineness at one time in the actual production process. Usually, the material is coarsely crushed through the jaw crusher, and then transported to the impact crusher or cone crusher by belt conveyor for secondary crushing and fine crushing, so as to ensure the finished product size meets the customer's demand. Xinhai has accumulated many years of experience manufacturing   crushing equipment , and developed   hydraulic cone crusher . With its unique technological design and scientific idea, hydraulic cone crusher immediately stood out among crushing and grinding equipment, and has been highly praised by global customers. Xinhai hydraulic cone crusher is developed with advanced crushing technology, which integrates machinery, hydraulic pressure, electric and intelligent control. Its new crushing structure combines with the optimized pyramid crushing cavity type and the fully ...

" 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!

Graphite is an excellent natural non-metallic mineral with good floatability and it is widely used in chemical, metallurgy, oil, automobile manufacturing and other industrial sectors. In the industry application, Graphite with larger flakes and higher purity will have wider application and high price. Therefore, in the process of graphite, protecting the graphite flakes and improve the impurity is key. As we all know, the graphite processing equipment has the large effect on the graphite concentrate besides the Graphite beneficiation process. What are the graphite processing equipment and how to choose it? At present, graphite beneficiation processes commonly adopt the flotation process. Therefore, the graphite processing equipment mainly include crusher and screening equipment, grinding and separating equipment, flotation equipment and concentration and dewatering equipment and so on. The crushing, screening and grinding of graphite are called graphite’s smashing. During...

There are many kinds of iron flotation equipment in Xinhai, like SF Flotation Cell, JJF Flotation, cyclonic micro-bubble flotation column. They are energy saving and high-efficient as well as good performance. Among those machines, the cyclonic micro-bubble flotation column is suitable for the coal minerals with the finer fraction that is smaller than 0.5mm or the flotation process of the meal mineral. The features of the machine are the combination of the flotation principle and the gravity principle. It can achieve the goal of three usages with one machine. That is, it can have the three flotation operations of primary flotation, scavenging and secondary flotation at the same time in one flotation column. It is of large capacity, high recovery rate, good processing indexes, less pollution of minerals, smaller ash in operation, well sold and has won the good reputation of the users. The SF mechanical agitation flotation cells that Xinhai Mining Technology and Equipment Inc. Manufac...

With the continuous copper ore mining, there is fewer and fewer high-grade copper ore, and copper ore block size is getting smaller and more complex. Ordinary flotation process seems not available for those ore. At this time, "poor, fine, miscellaneous" copper ore dressing process - the biological leaching process was born. The following is a brief introduction of biological leaching of copper production line. Common microbe mineral processing technology are heap leaching and leaching. Heap leaching means to heap mined ore, and then use microbe leaching solution. Due to its production cost is low and less pollution, it has been widely used. Situ leaching is to use a chemical solvent or microbial leaching solution to inject underground mines copper and dissolve copper and other valuable metals, then collect the dissolved rich liquid. This kind of processing method is the combination of mining and mineral processing, and there is no need to ship the ore out the ground whic...
