In recent years, with unceasingly increase of quantity of cleaning and processing coal, the development of coal preparation process with dense medium in the coal preparation plant has been promoted. In dense medium cyclone coal preparation, centrifugal slurry pump must always be used for feeding materials. When feeding materials with pump, the actuating medium is fluid-solid two-phase slurry which is a mixture of water, coal, gangue and magnet powdered ore. Because the working condition is very bad, serious partial wear to the flow components of pump is caused, which not only reduces the operational reliability of pump, but also reduces the service life of pump[2-4]. Therefore, besides energy saving and high efficiency, higher requirement to the operational reliability of pump is also proposed at coal preparation plants. There will be great significance for safe production to study the wear location and wear process of centrifugal slurry pump used in dense medium cyclone, and to reduce the wear degree of the slurry pump.
