Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. Coal has very wide using fields in our daily life. SBM crushers and grinding mills are neccssary equipments in coal processing.

Natural coal is feeded evenly into jaw crusher through belt conveyor, after crushed, it enter into impact crusher or cone crusher for fine crushing. Final it is screened out by screening machine.

In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm. So coal processing in coal preparation plant includes coal crushing and coal milling.

Coal crusher is the main crushing machine used in coal crushing plant. Coal crushing plant consist of many types of crushers, vibrating feeder, screen and grinding mills. Coal crushing equipments include jaw crusher, impact crusher, cone crusher hammer crusher and mobile crusher etc. Vibating feeder, screen and washing machine are also the coal processing equipments. These complete coal crushing plant produce small coal particles for further grinding process.

In the coal grinding process, the degree of grinding required depends on the type of coal used. Coal with a low volatile content requires a high ignition temperature and must be finely ground. Coal with a high volatile content, however, must not be ground too fine, otherwise the volatiles will be expelled too quickly to be able to mix properly with the combustion air.

SBM Machinery has the best of technology and experience for Iron Ore beneficiation in the form of gravity separation technology and the Magnetic separation process route. Several beneficiation plants have been upgraded with latest improved technological equipment and built in India by SBM Machinery for upgradation of Iron ore, for use as Sinter grade fines as well as concentrates used for pelletisation plant.

In industrial and agricultural production, iron is the most important structural material. Iron alloy has a wide range of application. It is of great importance especially in the uses of national defence and wars, which mainly depend on the contest of iron and steel. The annual output of iron and steel represents a country's level of modernization.

With a high magnetic field intensity, this machine can make a continuous row of ore feed and discharge. It also has enough working clearance and high processing capacity. wet drum permanent magnetic ore separator is widely applied in the separation of various kinds of iron ores and gold ore. In order to increase the grade or capacity, several sets of wet drum magnetic separators can be installed in series connection or parallel connection.

The Iron Ore Beneficiation has taken an important position in aligning plant strategies. Leading professionals from the industry have decided to put in efforts to spot ways to make the process more energy efficient, aiming at zero waste management for sustainable development which is synonymous with the concern for environment along with its social and economic goals. Today, with metal companies being freely permitted to import rich ores at low tariffs, mining these lean ores makes bigger challenge to have an economic sense, in order to effectively utilize & conserve the resource.

Processing of the iron ore includes iron crushing and screening. 40% of the iron ore produced is in the form of lumps which is subjected to crushing. SBM Machinery has installed a crusher of 150 tph capacity which is adequate to the production of 0.45 mtpa. The lumps production from the mine is estimated to be about 0.26 mtpa. Hence the capacity of the existing crushing plant will be adequate to handle the total production of 0.26 mpta of lumps (40% of total production of 0.65 mtpa). One screening plant of 100 tph capacity available is adequate to handle the total production of the mine.

A mineral is a naturally occuring, homogeneous, solid with a crystalline atomic structure. Crystallinity implies that a mineral has a definite and limited range of composition, and that the composition is expressible as a chemical formula. Some definitions of minerals give them as inorganic materials, however both diamonds and graphite are considered minerals, and both are primarily comprised of carbon, which would make them organic.

In the field of extractive metallurgy, mineral processing, also known as mineral dressing or ore dressing, is the process of separating commercially valuable minerals from their ores.

Mineral processing is art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sampling and analysis and dewatering.

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sampling – moval from a given lot of material a portion; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.

Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material.

Sampling is done either by hand or by machine. Hand sampling is usually expensive, slow, and inaccurate, so that it is generally applied only where the material is not suitable for machine sampling (slimy ore, for example) or where machinery is either not available or too expensive to install.

Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic or electric (magnetic and electrostatic separation), and physicochemical (flotation separation).

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water contained in particles. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

The equipments of mining production line cover feeder, crusher, ball mill, classifier, vibrating screen, rocking bed, magnetic separator, mix tank, flotation machine and so on.

Ore is a volume of rock containing components or minerals in a mode of occurrence that renders it valuable for mining. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Mine ores undergo ore processing plant to extract and recovery ore.

In the field of extractive metallurgy, mineral processing, also known as mineral dressing or ore dressing, is the process of separating commercially valuable minerals from their ores.

Generally, the complete ore crushing plant consists of jaw crusher, ball mill, classifier, magnetic separator, flotation machines, thickener, dryers and other major equipment, such as vibrating feeder, bucket elevator and belt conveyor. This production line feature with high efficiency, low energy, high capacity, economical and so on.

Following grinding in the ball mill, the material is returned via the sump to the secondary hydrocyclone for resizing. The trash screen removes wood from the old workings that may have found its way into the processing circuit. The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation C the size required for the cyanide to be able to 'see' the gold in the leaching process.

Limestone crusher used in stone quarry. In stone quarry, there are several types of stone crushers that can be used in limestone crushing plant.

Ore minerals are usually found within and among grains of other ore minerals or (relatively) worth less gangue minerals, This fact makes the processing of some ores more complicated than others. For instance, a complex sulphide ore containing microscopic particles of sphalerite within small blebs of galena or other sulphides presents a special challenge to the metallurgical engineer, that is, to design a milling process that will liberate these various constituents from each other as cleanly and economically as possible so that each may be recovered.

The procedure of the mineral processing flow goes like this: the ore is first sent to jaw crusher for primary crushing. Then the ore with a proper size for secondary crushing will be sent into the ball mill for fine crushing and grinding. The ore powder discharged from the ball mill will be sent to the next procedure: classifying. Because of the different sedimentation rate due to the varied specific gravity, spiral classifier can clean and group the ore mixture. The cleaned and gouped mixture is sent to magnetic separator, due to the different susceptibility, magnetic substance can be separated from the mixture under magnetic and mechanical force. Then the mixture is sent to flotation machine, according to the features of different ores, we can add different additive into the mixture to separate the ore we want from the mixture. `After the separation from the mixture, the ore we want always contains a lot of water, we need a thickener to have it concentrated first and then dried by a drier; eventually we can get dry ore.
