Bag massagers and deblocking devices are necessary for materials that pack above the discharge spout or become severely agglomerated when stored in bulk bags. They are designed to continuously induce material flow through the discharge spout of the bag. Massage Paddles Bag Flow Aid: Each paddle is actuated by a 6” bore pneumatic cylinder that raises the paddle to a vertical position with the flow aid portion of the paddle reaching 15° past vertical. Heavy Duty massage paddles utilize two 6” bore pneumatic cylinders per paddle. Bag Flow Aids Retracted position Mid Stroke Position Complete material discharge from the bulk bag is achieved as the Massage Paddles reach the fully extended position. The pneumatic cylinder’s position and resultant geometry as the rods extend provide superior mechanical advantage causing packed materials to easily discharge from the bag. With the Massage Paddles in the lowered position the full bag sets on the top plate and the discharge spout of the bag is feed through the semi-circular cut outs in each paddle. A heavy duty steel plate with a formed angled end and semi-circular cut out provides greater surface area contact of the paddle onto the bag. A 6” pneumatic cylinder provides over 2200 lbs. of force while raising each massage paddle into the bottom and side of the bulk bag. The massage paddles controls can be automatic and/or manual operation. In the automatic mode the paddles are actuated by a start/stop signal from downstream equipment.
