Porcelain ball
Opening a single or multiple circular holes along the diameter of the ball not only solves the problem of ball rotary resistance, but also increases the voidage and specific surface area of the packing. This improves the distribution and diffusion of the liquid. Porous porcelain balls are widely used in petroleum, chemical and natural gas industries to replace inert porcelain balls as supporting and covering carriers for catalysts.
