<P>PROBLEM TO BE SOLVED: To improve removal efficiency of deposited powders while controlling increase of the facility cost. <P>SOLUTION: When metallurgical coke A is passed through a sieve 2 and divided into small-and-middle lump coke B and powder coke C, air is blown on the sieve 2 by a blower 3. The blower 3 is placed so as to blow air on the sieve 2 on the upper stage from the inclined downstream side, and the blower 3 has a degree of wind pressure which allows the small-and-middle lump coke B to roll over and the powder coke C to be blown away. <P>COPYRIGHT: (C)2012,JPO&INPIT |
