Wheel dryers, with the desiccant bonded into a porous wheel rotating steadily through the drying and regeneration stages, have a reputation for greater drying stability because the desiccant is at a constant level of activity as it passes through the drying stage rather than the stepwise efficiency between regeneration stages of a traditional desiccant dryer.
The patented KP bonding process uses hollow glass spheres rather than traditional aluminum oxide as a filler material to provide additional strength to the bond post, creating a porous wheel finish that resists loading and burning.
Conventional porous wheel production depends on an added pore inducer, which can result in grains clumping around pores within the finished wheel.
In addition, a range of highly porous wheels using the same bond will be launched shortly which can be used for creep feed grinding of turbine industry components.
