    • PURPOSE:To produce efficiently an annular green compact at a low cost by inscribing a porous core with a rotary drum provided with discharge holes, supplying a liquid material contg. pulverous powder into the core and dehydrating said material under high speed rotation. CONSTITUTION:The core 2 of the porous ceramic is installed to inscribe the rotary drum 1 having the discharge holes for liquid and gas on the outside periphery. Filter paper or filter cloth 3 is adhered into single or multiple layers by the liquid to the inside surface of such core 2. The complete powder mixed with various kinds of necessary pulverous powder materials is then suspended in methanol, etc. and is sprayed into the core 2. The powder is dehydrated by rotating the drum 1. The green compact 5 is taken out together with the core 2 after the dehydration and is dried, by which the green compact 5 is obtd. The green compact 5 is subjected to working and sintering to be made into the product having a prescribed size and shape. The large-sized annular product is thus manufactured without using dies and press machine.
