Hengchang mining machinery has been committed to providing customers with more professional services in the turnkey solutions for a mineral processing plant, optimized its services continually, and formed its own set of service system, besides. The following is the detailed flowchart of Hengchang mineral processing plant services. Hengchang proceeds from every detail, creating the comprehensive green and efficient mineral processing plant for all customers.

Rock that can be processed at a profit is called ore. To extract the minerals carrying the valuable metal from the ore, a combination of separation operations, typically known as mineral processing or ore beneficiation is required.

Ball mills are now an obsolete technology for the global cement industry, mainly on account of high specific power consumption, limitations on the throughput rates, as the modern and the latest state-of-the-art technology, is not only for lower specific power consumption, very low noise level and comparatively lower space requirement.

Modern large to very large cement plants are using Vertical Roller Mills ( VRM), Roller Press system alone in close circuit, or Roller Press with ball mill in close circuit, for raw grinding ,fuel pulverization ( grinding of solid fuels like coal ,pet-coke and lignite or a combination of these fuels ) and finish grinding. ( manufacturing of various varieties / types of cements ) .This three-in-one VRM ,combines drying ,classifying and grinding functions, is highly efficient w. r. t. power consumption and throughput , besides the very low noise levels i.e. quite eco-friendly to the industry.Currently more and more mineral processing industries globally are switching over to these large capacity ( capacities of +1000 TPH ) are already operating in some plants.

Ball Millis primarily used for fine grinding. It is key equipment which repulverises the material after it is crushed.Kefid company has been amongst the pioneers for many years in the design and application of milling systems for the size reduction of a wide variety of materials including minerals, ores, and coal. There are two kinds of ball mill, grate type and overfall types due to different ways of discharging material.

Ball Mill mainly includes the inlet part, outlet part, revolved part ,drying part(reducer, drive gear, engine , control panel). The main body of the grinding chamber adopts the welded frame and the liner is replaced. The revolved gear adopts the welded technique, and there are abrasion liners, which have good performance.Ball Mill is widely used in powder-making production line including cement process, new-type building material, refractory material, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

Niobium, formerly columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. It is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite.

It was not until the early 20th century that niobium was first used commercially. Brazil is the leading producer of niobium and ferroniobium, an alloy of niobium and iron. Niobium is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. Although alloys contain only a maximum of 0.1%, that small percentage of niobium improves the strength of the steel. Niobium is used in various superconducting materials. These superconducting alloys, also containing titanium and tin, are widely used in the superconducting magnets of MRI scanners. Other applications of niobium include its use in welding, nuclear industries, electronics, optics, numismatics and jewelry. In the last two applications, niobium's low toxicity and ability to be colored by anodization are particular advantages.

Niobium and tantalum do not occur naturally as free metals, but are essential components in a range of mineral species. The majority of these are oxide minerals; silicates of niobium and tantalum also substitute for major ions in a number of other minerals, in which they typically have low concentrations. The vast majority of the economically important species are oxides.

Extraction methods used to extract the tantalum and niobium are similar to other comparable metal occurrence. Factors that dictate the choice of extraction methods include: physical and chemical properties of mineral ore, the tonnage and grade and type, geometry and depth of field. The most common extraction methods are surface (or open) and sub- surface (or underground) mining, or a combination of both. A significant amount of niobium and tantalum are extracted by artisanal mining and small-scale.

In recent years, several advanced technologies have been developed to improve the separation of finer materials. As a leading company in mining industry, we can supply our consumers with high-tech and high quality niobium ore beneficiation equipment. Niobium ore beneficiation equipment for Brazil has lot selectivity. Our most popular products are crushing equipment, grinding equipment, sand making equipment and separating machine. For niobium ore crushing, you can choose niobium ore jaw crusher, cone crusher, impact crusher and grinding mills such as ball mill, vertical roller mill and super thin grinding mill. For niobium ore separating, you can use our magnetic separator, flotation separator or gravity separator.
