ABSTRACT:
A high-speed fine pulverizer wherein a fixed top grindstone is mounted in a pulverizing chamber with a reduced pressure-tolerable mechanism, a rotating bottom grindstone is arranged in opposition thereto and mounted firmly to a rotating disk with a plurality of ejection wings for reduced pressure and disposed around the rotating grindstone, and an intensive reduced-pressure jet stream is caused by the high-speed revolution of rotating bottom grindstone to such air from a central opening of fixed grindstone, thereby forcedly passing the pulverizing raw material fed from said opening through the clearance between both grindstones at high speed while whirling it so as to be finely pulverized, wherein the pulverizing raw material can be pulverized finely at ambient temperature without a rise in temperature, allowing the conversion of foods etc. to powder without thermal transmutation. The invention can also include equipment for producing finely pulverized powder, including a high-speed fine pulverizer and an air classifier.
