PURPOSE:To get a uniform slurry by a method wherein a limited portion is arranged in a hopper part and agitation of slurry is performed with an exlusive pump under a desired number of rotation. CONSTITUTION:A slurry agitating small chamber 2 having through-pass holes 1 at a lower part thereof is arranged at a central part of a bottom of hopper C, slurry in the small chamber 2 is sucked with clean liquid at the hopper C by a suction pump P1 and then supplied to an injection gun E. The upper clean liquid in the hopper C is sucked with another suction pump P2 and injected into the small chamber 2. With this operation, grinding particles or grains coming into the small chamber 2 from the lower through-pass holes 1 are forcedly agitated, resulting in that quite uniform slurry can be obtained. |
