The filling of its multi-faceted hollow spheres is constant, which reduces the mutual friction between the filled hollow spheres. With a good understanding of the environment for film packing, it is now used for installation or method filling of circulating sludge systems. Its multi-faceted hollow sphere packing device is an important component of ecological equipment, and attention has been paid to how to improve filling to improve treatment. Generally, fillers can be classified as industrial fillers, solid fillers, and mesh fillers. Due to different usage environments, there are many other classifications that can be used for different types of fillers.

It is worth mentioning that polyhedral hollow sphere packing refers to the lazy solid material contained in the packing tower in chemical engineering, which serves as the contact surface for gases. Its polyhedral hollow sphere packing, also known as packing, refers to the solid material used to improve processing performance, mechanical properties of products, and reduce costs. It adopts special drawing and manufacturing processes to insert and fix wires in corrosion-resistant, polyhedral hollow sphere packing has excellent material selection and formulation processes, and moderate flexibility.
