Air Blaster

Air Blaster

Bulk solids, particularly fines when stored in hopper /bin / silo, do not flow smoothly resulting in phenomenon like rat holing, bridging, arching. Air Blaster when used alongwith suitable liners, prevent blockages and buildup in critical applications. Generally these clogging can be removed by the liners itself. However in case of inadequate hopper half angle and opening or discharge area (diameter or diagonal); the blockages become critical where the blasting system is employed as an aid to the liners.

A specified quantity of compressed air at 4-8 bar (60-120 psi) is released in a few milliseconds into the bin, at the position of the blockages. The impulse of the blasting force (the energy released) overcomes the compressive strength of the material and thus, free flow is restored.

The Air-Blasters are fired in an adjustable sequence by means of PLC system, to effectively generate free flow. As the quantity of air is small in proportion to the volume of the bin, the energy is dissipated, causing no harm to the structure.
