china wet process ore minerals grinding ball mill - china

Ball Mill Price, Grinding Machine, Wet Ball Mill manufacturer / supplier in China, offering Wet Process Ore Minerals Grinding Ball Mill, Hot Sale Mining Equipment Vacuum Rotary Drum Filter with Low Price, High Quality separation High Weir Single Spiral Classifier for Sale and so on

Ball Mill is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control.The hollow shaft uses steel casting, the inner lining can be dismantled and changed, and the rotary rack wheel uses casting gear hobbing and inside the cylinder there is wear-resisting lining board which has fine abrasion performance. This machine has stable operation and reliable performance

Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications. The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls will fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the single-layer partition board and into the secondary cabin in which there are flat lining board, and in the lining board there are steel balls to further grind the materials. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.Spare parts display of ball mill                                                                                                          Packing & Delivery

Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads.  This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here

As the mill revolves, lifters assist in picking up the grinding charge and elevate it to an angle at which gravity overcomes friction and centrifugal force. The charge then cascades downward, effectively grinding particles of material within the mill by continuous, repeated impact and attrition action

Grinding Mill speed is one of the factors affecting the character of the cascading charge. As shown in the illustrations, the lower the percentage of critical speed, the smoother the flow of balls from top of charge to bottom. Higher percentage of critical speed is used for impact grinding of large feed. Lower percentage of critical speed is used for attrition grinding when a fine product is desired. The graph below will be helpful in determining percentage of critical speed when internal mill diameter and RPM are known. A Grinding Mill is a revolving cylinder loaded to approximately one-half its volume with steel rods, balls or pebbles

Grinding mills reduce particle size by impact, rolling and sliding. Of the many types in use, the cylindrical mill, which employs a cascading mass of balls or rods, is universally used for the size reduction of hard, moderate to highly abrasive materials, such as minerals, ores, stone, and chemicals. ,

A cylindrical mill, when operating under uniform conditions, will produce a uniform product. Wear on grinding surfaces has little effect on capacity or product size. Very little maintenance is required with these mills, downtime being a negligible factor in their operation. For continuity of operation, the cylindrical mill has no equal

Grinding mills of this type will give you dependable, trouble-free operation year after year, with “planned” periods of stoppage for renewal of parts. Initial cost is distributed over a long operating period. Many grinding mills are still in service after more than 40 years of almost continuous operation. Ton for ton of material handled, the cylindrical type mill has proved to be the most economical investment for reducing moderate to extremely abrasive materials

911Metallurgist sources manufacturers of all the proven mill designs in a “small” range of sizes — your assurance of getting the most suitable mill for your purpose. Best grinding efficiency and economy can be obtained only when the type and size of your mill is matched with your grinding job. Mills can also be furnished with modifications to suit any special application

The choice between wet or dry grinding is dependent upon the use of the product or the subsequent process. It is imperative to dry grind many materials because of physical or chemical changes which occur if water or a solution are added. Wet grinding with water (or with a concentrated solution of the soluble salts being ground) is generally preferred, because of the overall economies of this operation

Another factor in choosing a grinding mill is the consideration of the feed size introduced into the mill, and the product required from the mill or mill circuit. This can be best illustrated by comparing two prevailing and diametrically opposite grinds

grinding mills - 911metallurgist

In the manufacture of standard cement by grinding cement clinker, the clinker is reduced from 1″ or finer down to a specific surface of 1750 sq cm per gram. This area can be produced by an open or closed circuit grind. The specific area method (which indicates the square centimeters of surface exposed per gram of material ground) is a most satisfactory method of determining whether a cement product will meet an accepted standard

In a typical cement plant employing closed circuit grinding, 1750 surface can be obtained with a finish grind of between 93 and 96% passing 200 mesh. This area requirement means that fines are not only desirable but necessary, and that a size analysis must show a distribution of material from approximately 80 microns down to less than one micron

Wet grinding ball mill in mining operation. Balls within mill retain their high grinding efficiency regardless of wear. Ball mills are used extensively for grinding metal bearing ores and abrasive minerals

When grinding ore prior to concentration, on the other hand, the grind is determined by the degree of reduction necessary to unlock the valuable mineral from the gangue. This gangue is undesirable and must be separated from the desired material. For example, the full-size illustration above shows a piece of coarse-grained magnetite. The grind necessary to unlock the magnetite is about 14 mesh. At this grind, almost every individual crystal of iron oxide is freed from associated gangue and the ground material is ready for magnetic concentration

Actually then, the ideal grind would be to reduce this ore down to 14 mesh particles—not finer, for any expenditure of energy to reduce this ore beyond the unlocking mesh size is wasted. Such a grind is impossible, but any grinding circuit should be controlled so as to minimize overgrinding. Some fine material is produced, but it is tolerated rather than desired

The product resulting from the reduction of a number of particles is dependent on two distinct shapes of grinding media—the rod and the ball. Here the term ”ball” is used to cover the entire range of grinding media which is spherical in shape, or roughly so

grinding mills - 911metallurgist

The principle of grinding action, rods as compared to balls, can be best understood by making a comparison of their contact with adjacent rods or balls. Rods making up a grinding charge are nearly parallel and tend to meet adjacent rods in line contact. Rods tend to bear only on the largest particles, thereby expending most of their crushing force on the over-size and allowing the fine particles a freer passage between the rods without being ground to objectionable fineness. Balls, on the other hand, meet adjacent balls in point contact and particles of material at these points are ground to a very fine state

Concavex grinding medium is an improved type of ball grinding media which offers more surface area per unit of weight, and has found extensive use in the grinding of cement clinker. The advantage of Concavex medium is its ability to increase mill capacity because of its interlocking shape and increased density per cubic foot of grinding charge. Surface areas for Concavex grinding media are given later

Ball mills are built in Overflow and Diaphragm types. In the Overflow mill the material is discharged by new feed moving into the mill and displacing a mixture of solids and water being ground within the mill. The diaphragm arrangement in a ball mill is a positive means of pumping pulp or dry material out of the mill. The gradient is steeper than in an Overflow type mill. A Diaphragm ball mill has a higher capacity and requires more power than an Overflow ball mill of equal ball charge

The Overflow rod mill is applied to wet grinding. The Center Peripheral Discharge rod mill is also used for wet grinding but produces a coarser product than the overflow type. Either the End or Center Peripheral discharge rod mill can be used for wet or dry grinding. Whatever the type, the rod mill is used to produce a coarse product, whereas the ball mill is used to produce a finer product

Should a ball mill grind be required, the relationship of the length to the diameter of the mill is important. Feed and product screen analyses, and the type of circuit (open or closed), dictate the proper diameter to length ratio of a mill

Colored line indicates hp-hr/ton required to grind a hard ore from 1/2″ to 65% minus 200 mesh; closed circuit, wet grinding. Black line indicates hp-hr/ton required to grind average cement clinker from 0.5″ to 96% minus 10 mesh; open circuit, dry grinding

grinding mills - 911metallurgist

The type of mill for a particular grind and the circuit in which it is to be used must be considered simultaneously. Circuits are divided into two broad classifications, open and closed. In open circuit, the material is fed into the mill at a rate calculated to produce the correct finished product in one pass through the mill. This circuit has been popular in the cement and chemical industries, although the present trend is toward closed circuit installations. The closed circuit is generally employed in the mineral dressing industry

In the closed circuit the material is discharged from the mill into a classifying device. The classifier separates and (1) returns the oversize material to the mill for further grinding, (2) delivers the fine material as finished product of that circuit. Material returning to the mill is called circulating load, and the ratio of this material to new feed may vary from a few percent to 600 percent or more

Several types of separators are used in closed circuit grinding. Vibrating screens with screen cloth as fine as 28 mesh are used to produce a mesh product from either wet or dry grinding circuits. Fine wet grinding circuits employ a classifier to separate a product varying from 10 to 325 mesh. Fine dry grinding circuits employ an air separator for products of 65 mesh and finer

grinding mills - 911metallurgist

In open circuit grinding the feed rate must be low enough to permit a longer retention time per particle within the mill. This assures that each particle of the incoming feed, however large, will be broken down to product size. As a result, many particles in the product are ground to sub-sieve size. In ore dressing, these fine particles are usually undesirable, and the additional power required to produce them is a wasted expenditure. However, sub-sieve size particles are sometimes desirable, where the properties of the finished material require it. Finished cement and pottery glaze are examples of products requiring fines in the micron sizes

In a closed circuit operation no effort is made to produce all the reduction during a single pass through the mill. Instead, every effort is made to remove a particle from the circuit as soon as it reaches the required product size. Quite often one of the largest particles of the feed, partially reduced, will be discharged, separated and returned to the mill several times before being completely reduced to the desired size
