Product Description wet overflow ball millThe ball mill is the key equipment for crushing the materials after they have been crushed. Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal mineral processing, glass and ceramics and other production industries for dry or wet grinding of various ores and other grindable materials. The main applicable materials include quartz stone, gold ore, iron ore, cement clinker, etc.Types:Based on its usage and structural characteristics, the ball mill can be divided into several types, including:Dry Ball Mill: Suitable for grinding dry materials.Wet Ball Mill: Suitable for grinding processes that require the addition of water or other liquids.Overflow Ball Mill: Materials are discharged through the overflow port at the bottom of the cylinder.Grate Ball Mill: Materials are discharged through the grate plate at the bottom of the cylinder.Tube Ball Mill: The cylinder is tube-shaped, suitable for long-distance material transportation.Application Fields:Ball mills are widely used in mining, building materials, chemicals, metallurgy, electricity, and many other industries for grinding various hardness materials and other substances.1. Energy Saving and Less Power Consumption: The matching of the drive and the grinding media can greatly lower the power consumption.2. The Flexible Design of the Discharging Port: The customers can decide whether the iron removing the device is required or not according to their demands.3. The Bigger Feeding Size: The reasonable design of the feeding port can increase the feeding output.4. Taking the Closed System to Decrease the Dust: Closed system, negative pressure conveying, small dust.Ore processing plant is also called beneficiation plant. It is a kind of production line of selecting kinds of mineral ores.The general process is : crush big mineral stone into small size (0-20mm) , grinding these small stone into powder (or slurry) , then separate the useful ore from the powder (slurry).There mainly have four kinds of separation method : (1) Flotation separation ,(2) Gravity separation (3) Leaching separation ,(4) Magnetic separation Flotation separation Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals..It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores".Gravity separation Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight.It suitable for Alluvial gold ,lead , chromium ect.Leaching separation Leaching is the process of extracting substances from a solid by dissolving them in a liquid.The leaching of precious metals such as gold can be carried out with cyanide or ozone under mild conditions.Leaching method suitable for Oxidized ore. Magnetic separation Magnetic Separation is which separating components of mixtures by using magnets to attract magnetically susceptible materials.It suitable for iron , Manganese ore ect.Ball mill Ball mill is the key milling equipment after material has been crushed.It used to grinding 0-20mm ore stone into powder (dry grinding ) or slurry ( wet grinding ) , after grinding , the ore size is around 120 mesh. Spiral classifier Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are a partially drained fraction containing the coarse material (called the underflow) and a fine fraction along with the remaining portion of the liquid medium (called the overflow).Flotation machineThis flotation machine is suitable for separating non-ferrous and ferrous metals as well as non metals such as fluorite and talc.The structure of flotation machine: this machine is mainly composed of pulp chute, mixing device, air charging system, mineralized bubble discharging device and electro motor.Magnetic separatorA magnetic separator is a device that uses a magnet to remove impurities and other magnetic materials from metalBall mill application:Ball mill is the key equipment for recrushing the materials after they are primarily crushed. It is an efficient tool for grinding various materials into powder. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material. Ball mill is widely used in metallurgy, mining, chemical, cement, construction, industrial and mining industries etc.Ball Mill Working Principle:The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The grinding materials are discharged through the discharging board thus the grinding process is finished.Ball Mill Structure:The machine is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Ball mill features: 1. The machine is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on.2. The hollow axis adopts the cast steel and the lining can be replaced. The big rotary gear is forged from cast rolling gears. 3. The barrel body is inlaid with wearable plates.4. The machine runs steadily and efficiently.How to maintain overflow ball mill?(1) Bearings suffer all burden of machinery, and good lubrication affect the service life of bearings, so the lubrication must be clean and sealed well, the main oiling places 1) Rolling bearings, 2) Roll bearings, 3) All gears, 4) Movable bearings and sliding plane.(2)The new strake is easy to loosen, please check often(3) Note that each part of the machine is working properly.(4) Pay attention to the wear degree of wear parts, and replace the worn parts on time.(5) Remove the dust on the under frame surface of installing movable device, which guarantees the fluent movement of machinery.(6) If the temperature of bearings boosts up, please stop the machinery and eliminate the problem(7) Please stop and check if hear the impact noise of rotary gearPREInstallation of ball mill and rod millBall mill and rod mill are widely used in grinding link in mineral processing. They have different advantages when they process ores. The first step of using them is to know how to install them.NEXRoutine problems solution of agitation tanksAgitation tank is necessary equipment in flotation divided into 4 kinds, ore slurry agitation tank, agitation store tank, lifting agitation tank and agitation tank for chemical reagent.Ball mill advantages:1. High milling efficiency2. Mechanically simple design3. Competitive capital cost4. Use of low cost5. No steel contamination of product6. Capacity to operate continuously at full load power draw7. Low rotational impeller speed with shallow charge depth providing reduced abrasion of impeller and body liner coverings
