History of Ball Mill

Ball mill appeared in the early 19th century; 1870 in the grinding mill, based on the development of a uniform size marker rod mill; in 1908 it created a self-mill without grinding media. 30 to 50 years the twentieth century, the United States and Germany have developed a roll bowl mill, roller mill and other vertical type disc pulverizers. This year is mine mineral processing equipment as an essential part of the ball is more rapid development of the.

Ball mill is the material being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ore dressing, and black glass ceramic and other non-ferrous metal production industries, and other various ore grindability of materials for the dry and wet grinding.

Ball grinding mill is a horizontal rotating device, outer gear, the two positions, lattice-type ball mill. Material from the feed device into the compound by air evenly into the mill screw shaft first warehouse, the warehouse there are ladder liner or corrugated liner, built in different specification steel balls, cylinder to convey ball into the action must generate centrifugal force After the fall height, produce severe impact on the material and abrasive.

To coarse grinding of materials in the first position after the board by the single compartment into the second warehouse, the warehouse lined with flat lining, steel ball inside, the material to further grinding. Powder discharged through the discharge grate plate to complete the grinding operation. Structural characteristics of ball mill from the feeding part, discharging Department, Rotary Department, Transmission Division (reducer, small transmission gear, motors, electrical control) and other major components. Hollow shaft with steel casting, lining Replaceable, slewing gear hobbing by casting process, the body inlaid cylinder liner wear, has good wear resistance.

Ball mill energy consumption in the course of work accounted for the majority of the whole process of cement production, including power consumption, integrated power consumption of cement accounts for about 60% -70%, so
how big the energy consumption of “downsizing” is a cement technology workers unremitting goal. Grinding equipment selection, based on cement and concrete properties (performance,mechanical properties, durability) as the core, not just the pursuit of the production process of reducing power consumption, but also to meet the needs of building energy saving.

“Standard density is low, a good additive compatibility, well age, high strength, help to improve the durability of concrete is the quality of cement concrete.” At the same time, also ensures the development of admixtures industry view, “admixture of cement industry can reduce the required particle bound to improve the performance of cement plays an important role.”

Dolomite Manufacting Process

The mineral is worked by shallow pits. During mining the Dolomite is taken care of into different grades depending upon the colours because they fetch different prices as well as, because their suitability is determined by the colours. The mineral is utilized invariably by means of fine powder. Few important mine-owners have their own pulverizing plants; others target pulverizers.

Dead burnt refractory dolomite is manufactured in rotary kilns. Generally high-grade dolomite, containing combined impurities under 3%, is selected for dead burning.

The dolomite after dead burning is cooled in either rotary or reciprocating recuperative coolers. The air useful for cooling gets heated and is also again used as secondary air for combustion within the kilns. When D.B. dolomite is manufactured having an additive, it’s important to use somewhat higher firing temperature so that you can shrink the dolomite inside a reasonable time-cycle in the kiln. It’s been accomplished by improved thermal efficiency in the kiln. Some of the means to attain higher efficiency have been using insulating brick-back of the basic lining inside the hot zone and the optimum using secondary air from your recuperative coolers, in order to grab because the accessible heat as is practical in the cooling of the product.

Dolomite Grinding Machine

Dolomite grinding mill will be the machine that is used to create dolomite into powder which popular in industry dolomite. Usually dolomite powder is 140 meshes, 325 meshes, 600 mesh, 1000 mesh, 1600 mesh. There are numerous forms of dolomite powder machine: ball mill, Raymond mill, trapezium mill, questionable grinding mill, and ultrafine grinding mill.

Gyratory Crusher

In quarry field, we always treat them as the two name of the same machine. But as it happens, gyratory crusher and cone crushers are not the same.
In basic concept, gyratory crusher is comparable to a jaw crusher that includes a concave surface along with a conical head; both surfaces are usually lined with manganese steel surfaces.
Cone crusher can be thought as the Upgrades Version of gyratory crushing machines. They are similar in operation, with less steepness in the crushing chamber and much more of a parallel zone between crushing zones. Cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and also the enclosing concave hopper, covered by a manganese concave or perhaps a bowl liner. And traditionally, in some area, we call it gyratory crusher too in mines and quarry.

Gyratory Crusher Application

In industry, Gyratory Crushers are machines which use metallic surface to break or compress materials. Mining operations use crushers, commonly classified by the degree that they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations.

Each crusher is made to work with a certain maximum size raw material, and frequently delivers its output to a screening machine which sorts and directs the merchandise for further processing. Mobile Cone crusher can crush rocks. In a mobile operation, these crushed rocks are directly combined with concrete and asphalt that are then deposited on to a road surface. This removes the need for hauling over-sized material to some stationary crusher and then to the street surface.

Selection Crushing Plant

The selection of crusher plant depends upon the kind and amount of material to be crushed. Gyratory and jaw crushers represent the majority of primary crushers used at mining operations today, although some operations use roll impact crushers, low-speed roll sizers and feeder breakers. Cone crusher  remain typically the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing.

Major Equipment Select
