There are many types of fluidizing "pads" on the market, depending on where you are. The two types I am most familiar with are 1) mesh screen rectangular pads and 2) bell-type cover pads. The choice has much to do with the nature of the material to be fluidized. If the material is light, fluffy, or easily fluidized, then the mesh screen type works best because it introduces a continuous flow of slightly compressed air into the bed of material to aerate it and allow it to flow more easily. If the material tends to pack, build up, or become difficult to move, then the bell-cover type (I've only seen steel construction, not ceramic construction) works best because as the air escapes it causes the cover to bang against the hopper wall, acting like a vibrator, to dislodge caked material.

Hot, or warm, fly ash flows very well and fluidizes easily so the mesh screen type pad works well. However, cool fly ash tends to become difficult to move so a rapper-type fluidizing pad, or "air cannon", helps to break up packed material.

Please send better description, or pictures, of the types you are referring to for better answers.
