EQUIPMENT FOR WIRE CLEANING
RG-3800 SHOT BLASTING MACHINE FOR WIRE ROD
The shot blasting machine is mainly designed for cleaning wire rods. The machine uses shot blasting cleaning process for descaling the surface of the wire and roughening the surface while also increasing treated metal’s resistance to corrosion. Compared to pickling line, shot blasting cleaning method is more effective, economic, and eco-friendly.

Features of Wire Rods Shot blasting Machine
The equipment uses a unique technology of having a rotating shutter (360°) and a double console crane for wire rod transportation, which significantly increases the production capacity of the equipment
In order to provide a better cleaning, during the shot blasting process the wire goes through a complex of operations: up-down rotation, left-right rotation, forward and reverse rotation. Additionally, the design of the equipment allows both inner and outer sides of the wire surface to get an even shot processing. After shot blasting the wire surface reaches the surface preparation standard of Sa 2.5 (very deep blast cleaning).
