DRYING, SIZING AND SHAPING PROCESS TO MANUFACTURE CERAMIC ABRASIVE GRAIN
A sol gel abrasive gain and the preparing method thereof are provided. The abrasive grains deriving from alumina powders have various shapes and sizes and can be used to make a bonded or coated abrasive product. The preparing method comprises: coating alumina monohydrate sol to a carrier backing by roller coating, knife coating or extrusion coating method, etc., drying the coating to a high-solid state in a continuous dryer such as backing treatment oven, festoon oven or drum dryer, then shaping and sizing by patterned rollers or screen web, etc., further drying the shaped gel and then calcining, impregnating and sintering the gel to obtain microcrystalline ceramic grains.
