Wavy-shaped sintered plate dust collector (also known as sintered plate dust collector) is made of sintered filter sheets, which are strictly mixed with various polymer powder compounds before casting and sintering. This forms a porous matrix, and then a special spraying process fills the gaps in the sintered plate matrix with ultra-fine dust particles less than 1-2 micrometers, achieving high dust removal efficiency and ultra-low emissions, meeting the requirement of smoke and dust emission concentration of 3-5 mg. It is particularly suitable for the treatment of ultra-fine dust from coarse rolling machines. The sintered plate not only has high dust removal efficiency but also a long service life, with domestic sintered plates lasting 8-10 years.
