摘要：
A rock dust blower and method draws rock dust from a portable supply of rock dust, in response to a flow of pressurized air, and entrains the drawn rock dust in a stream of the air for direction to selected surfaces of a coal mine. The supply is contained in a substantially vertical column and rock dust is drawn from the column along a peripheral edge of the column located adjacent the lower end of the column to thereby militate against cavitation of the rock dust adjacent the center of the column as rock dust is drawn from the supply. A vibrator mechanism can be employed to transmit vibration to the supply and thereby facilitate an even distribution of rock dust in the supply and a smooth and continuous flow of rock dust as rock dust is drawn from the supply.
