PURPOSE: An apparatus for preventing deposition and adhesion of fine granulated slag in a mesh roll hopper is provided to reduce working load when removing granulated slag adhered to the inside of the hopper, improve operating ratio of the granulated slag, and remove factors generating safety accidents in advance by having the fine granulated slag flown into the mesh roll hopper not deposited, thereby preventing the fine granulated slag from being deposited to be stuck to the hopper. CONSTITUTION: The apparatus comprises bubbling air rotational fins (25) from the inside of which air can be ejected, wherein the bubbling air rotational fins (25) can be rotated in a propeller type; a motor (29) for driving the bubbling air rotational fins (25); concentration detecting rotational fins (26-1,26-2) stirring granulated slag deposited in the lower part of a hopper and detecting the concentration of fine granulated slag depending on the amount of the fine granulated slag; motors (27-1,27-2) for driving the concentration detecting rotational fins (26-1,26-2); current detecting parts (36-1,36-2) for detecting the content of the fine granulated slag by operating the concentration of the granulated slag into current; a fine granulated slag detecting part (37) for detecting the content of the fine granulated slag; a control system (35) being driven according to output signals of the fine granulated slag detecting part (37); a flow rate transmitter (34) and a control valve (33) controlling the amount of air ejected by adding or subtracting the output according to output of the control system (35); a check valve (30) for preventing water in the hopper from being flown backward to an air pipe; and manual valves (31-1,31-2) installed at the front and rear parts of the control valve (33) so that repairing can be done during breakdown.
