Preservation line working from Mesblate is for blasting, painting and drying of steel plate, steel sheet and steel strips in Vietnam. Heavy duty roller conveyor feed steel plate into shot blasting machine chamber where 10 pieces of blasting wheel clean the sheet metal in different angles. Brushing and blowing device collect used steel shots to keep top surface clean. Airless spaying nozzles apply prime or paint at required thickness on plate. And hot air in drying chamber will heat plate dry while out of drying chamber.
