PURPOSE: Provided is a micro-grinding apparatus to generate proper amount of impact according to the condition of raw materials in order to improve grinding effect without alternative grinding ball to minimize abrasion and damage of grinding blade and case. CONSTITUTION: The micro-grinding apparatus further comprises a cooling part mounted outside a case(100) having a number of cooling pins(110a) and a flow duct(110b) for passing cooling fluid and a rotational axis(210) fixed with frictional blade(210a) for inducing co-impaction of raw material corresponding to a grinding blade(220), in addition to conventional constructions such as the case(100), a grinding part of raw material; and a power supply part.
