Nanomaterials, e.g. metal oxides, nanoclays or carbon nanotubes tend to be agglomerated when mixed into a liquid. Effective means of deagglomerating and dispersing are needed to overcome the bonding forces after wettening the powder. The ultrasonic breakup of the agglomerate structures in aqueous and non-aqueous suspensions allows utilizing the full potential of nanosize materials.
Ball mill for nanomaterials Construction Waste Crusher Construction waste refers to the construction, construction units or individuals to construct, lay or demolish all kinds of buildings, structures and pipe networks, etc., and generate the spoil, spoil, waste, residual mud and other wastes generated during the repairing process.
