The present invention aims to provide an ice shaving machine that can produce a quantity of shaved ice powder without a fuss and that makes less noise. An ice shaving machine has an ice shaving chamber in which is provided a slit that a shaving blade faces, a rotary vane for rotating ice charged into the ice shaving chamber, a motor mechanism for rotating the rotary vane, a rotating hopper that stores the ice in the ice shaving chamber and coaxially rotates with the rotary vane, and an ice stocker that is provided above the rotating hopper and has openings at the lower and upper ends. The rotating hopper has a diameter that is reduced upwards, and the ice stocker coaxially rotates with the rotary vane and the rotating hopper.

A suspending agent-containing slurry is disclosed which comprises a dispersant and a particulate suspending agent having a particle size distribution in which the particle diameter at weight-cumulative 95%, from the minimum particle size, is 1 &mgr;m or smaller. A method for efficiently producing the suspending agent-containing slurry is also disclosed. A process for suspension polymerization by use of the suspending agent-containing slurry is further disclosed. The slurry not only has such an excellent suspending ability in suspension polymerization that it enables the production of vinyl polymer beads having a narrow bead size distribution, but also is capable of retaining this ability over long and of exhibiting the same ability even when it has a high concentration. The suspension polymerization process enables vinyl polymer beads having a narrow bead size distribution to be produced efficiently due to the use of the slurry.
