ABSTRACT:
A grinding machine includes a casing with a top plate unit, two grinding units installed on the top plate unit, and a driving unit for activating the grinding units. The top plate unit has a dust inlet slot formed therethrough so as to permit dropping of dust from the corresponding grinding unit into the dust inlet slot. The casing has two side chambers communicated with the dust inlet slots, and a middle chamber which is located between the side chambers and which receives a filtering unit therein. A dust-collecting chamber is located in a bottom portion of the casing and is communicated with the side chambers and the middle chamber. An exhaust fan unit is disposed in the middle chamber and is located over the filtering unit to draw dust from the dust-collecting chamber in order to discharge the same from the casing. Two fireproof dust-guiding units are disposed within the side chambers respectively so as to guide dust from the grinding units to the dust-collecting chamber through the side chambers and so as to prevent fire sparks from contacting a filtering sheet of the filtering unit.
