XINAN is specialized in producing series of dust removal, conveying and burning equipments. A large quantity of chips, shavings and dust produced in the machining process are sucked into central dust collector and them forced to pass through the separator to enter the silo. The wood waste from the silo is transported by screw conveyer through the excretive valve to the boiler. The whole system not only realizes the mechanization to reduced labor intensity but also saves a large quantity of coal and keeps the environment clean. ■ Design, manufacture, installation and trial run of pneumatic dust removal system for wood machining workshop ■ Design and manufacture of pneumatic dust removal system for sander ■ Design and manufacture of waste conveying-burning system ■ Manufacture of efficient pneumatic separators with a variety of specifications ■ Manufacture of pneumatic pulse sack-like dust removers which a variety of specifications ■ Manufacture of residue conveying fans
