dc.description.abstractEconomic sand accumulations are found along Eastern and Southern coastal belts of Sri Lanka These mineral sand deposits consist of ilmenite, rutile, zircon, garnet, magnetite, monazite, sillimanite and quartz. Mineral sand separation plants separate minerals using their physical properties such as specific gravity, magnetic properties and conductivity. Garnet is produced as a by-product of this separation process and is removed as a tailing. Southern coastal areas of Sri Lanka such as Tangalle, Ussangoda and Kirinda are known for large scale garnet sand accumulations. Garnet is a mineral with relatively high hardness value. Therefore it can be used as an abrasive material for various applications such as tool sharpening, wood polishing, and metal polishing. Water jet cutting machines use garnet in fine powder form as the abrasive material. There are two types of abrasive materials, namely coated abrasives and bonded abrasives which can be made out of garnet sand. Bonded abrasives are used mainly in abrasive wheels where a suitable bonding material binds the abrasive. These abrasive wheels can be used for removing very fine quantities of material from the work piece. Grinding is a process of removal of particles and surface generation used to shape and finish components made of metals, wood and other materials. Grinding process needs an abrasive product usually a rotating wheel in contact with a work surface. The grinding wheel is composed of abrasive grains held together in a binder. These abrasive grains act as cutting tools and remove very small chips of material from the work piece. Bonded abrasives are used for this sort of applications. Various bonding materials such as vitrified bond, rubber bond, shellac bond, metal bond are used in abrasive wheels. This research was carried out to produce an abrasive wheel using Sri Lankan garnet sands and different types of bonding agents. Performance of each combination was tested.en_US
