(1) Product Description
KK Perforated Ceramic ball is developed
on the basis of inert ceramic ball. It has
an adequate mechanical strength, chemical
and thermal stability as the normal inert
one; ferthermore it has higher dispersion
and flux of the fluids, more surface area
and lower resistance resulting from the
perforated holes on the ball body, As a
new efficient support and covering material
of catalyst, it has been widely used in
oil refinery, chemical, fertilizer, natural
gas and environmental protection industries
since put into market.
