Coal passing through the 4.75mm screen but retained on the 600mm screen was placed in a mixing drum. Once all the coal was screened and transferred to the mixing drum, it was mixed for approximately 5 hours. The material was then transferred to containers capable of holding about 10kg of coal sample. Forty five samples were obtained in this way.
Abrasion testing. Abrasion is the property of the coal which describes its propensity and ability to wear away machinery and undergo autonomous grinding. While carbonaceous matter in coal is relatively soft, quartz and other mineral constituents in coal are quite abrasive. This is tested in a calibrated mill, containing four blades of known mass.

Sep 01, 1990· Abrasion index is expressed as milligrams of metal loss per kilogram of coal. Du Toit and Bonapace11 noted that during the test, high-stress abrasion occurs in the early stages of operation, when large particles are being comminuted, and scratching abrasion and erosion occur when the charge is practically reduced to powder.

About Quality of Coal: Abrasion Index. Jun 05, 2013 · Abrasion index is an index that shows the abrasive properties (abrasion) of coal on the part of the equipment used to grind the coal before being used as fuel in certain combustion systems. The higher the index the abrasive coal the higher the maintenance costs of the coal grinding equipment.
the amount of abrasion is mainly determined by the magnitude of the relative hardness of materials in friction. In the case of a coal particle in friction against the YGP tester blade, abrasion of the mineral inclusion is defined as /h h i b where h i and h b respectively represent the mineral particle hardness and the blade hardness.

al., 2001). Coal quality is specified in heating value, ash content, moisture and sulphur content, with additional properties like volatile matter, fixed carbon, ash fusion temperatures, grindability, abrasiveness index etc. The effects of the above coal quality properties includes fouling, slagging,
Sapozhnikov and G Caking Index tests are used in certain areas of the world as resistance of coke to impact and abrasion during removal from the coke oven and transportation, and the abrasion that percentage of each rank of coal in your blend, troubleshoot quality problems, and evaluate how coking operations impact your final product
Apr 05, 2013· Coking coal is a naturally occurring sedimentary rock found within the Earth’s crust. Categories of coking coal include hard coking coal, semi-hard coking-coal or semi-soft coking coal, and coal for pulverized coal for injection (PCI). These apply to the different quality grades of the coking coal, all of which are used in ironmaking.

Sep 25, 2018· Metallurgical coal is also called ‘met coal’ or ‘coking coal. It is a bituminous coal which allows the production of a coke suitable to support a blast furnace (BF) charge. It is distinguished by the strong low-density coke produced when the coal is heated in a low oxygen (O2) environment or in absence of air to reduce mineral impurities
