Crush BK CRUSH STRENGTH Expotech USA

As the axial crush strength is much higher, it is not representative of the catalyst behavior in the reactor. Therefore the radial crush strength must be measured for industrial purposes (the type of crush strength measured must always be specified). D6175-98 procedure refers to extrudates. In this case only the radial measurement can be performed.
