Recently, a roller conveyor shot blasting machine from Puhua Heavy Industry successfully completed production debugging and, after passing inspection, was packed and shipped to Southeast Asia. This equipment will be delivered to a local steel structure manufacturing company, primarily for surface cleaning of steel plates and sections, providing reliable pretreatment for steel structure painting.
This roller conveyor shot blasting machine was customized by Puhua Heavy Industry for its Southeast Asian client, configured to meet the typical needs of the steel structure processing industry. The equipment uses a continuous roller conveyor system, allowing workpieces to pass through the shot blasting chamber at a uniform speed, receiving shot from multiple blasters at different angles, achieving efficient and uniform surface cleaning.
This equipment is mainly suitable for rust removal and oxide scale removal of long steel materials such as steel plates, H-beams, and I-beams. The client's production line primarily processes steel structure components, and shot blasting is an indispensable process before painting.
During rolling, welding, and storage, oxide scale, rust, and welding slag form on the surface of steel structure components. If these deposits are not properly cleaned, they will directly affect the coating quality and corrosion resistance lifespan. Shot blasting solves two problems simultaneously: thoroughly removing surface impurities and creating a uniformly rough surface, providing a good adhesion base for the coating.
After shot blasting, the steel surface has effectively removed oxide scale and rust, exhibiting a uniform metallic luster, and its cleanliness meets the standards required for coating. The surface roughness is moderate, satisfying the coating adhesion requirements without excessive paint consumption. The cleaned components can directly proceed to the spraying process.
In recent years, Southeast Asia has seen continuous development in infrastructure construction and manufacturing, leading to the increasingly widespread application of steel structures in buildings, bridges, and industrial plants. The demand for surface treatment equipment from steel structure processing companies has also increased accordingly.
Roller conveyor shot blasting machines, due to their continuous operation, high processing efficiency, and suitability for mass production, have become commonly used surface treatment equipment in the steel structure processing industry. The equipment shipped to Southeast Asia this time was customized to meet the production capacity needs of local customers.
Puhua Heavy Industry has accumulated many years of manufacturing experience in the shot blasting machine field, and its products are exported to many countries and regions. During the delivery of this equipment, Puhua Heavy Industry provided the customer with a full-process service encompassing solution design, equipment manufacturing, factory inspection, and shipment.
After the equipment is shipped, Puhua Heavy Industry will provide the customer with installation guidance and operation training to ensure the equipment can be put into use smoothly upon arrival at the site. Puhua Heavy Industry stated that it will continue to monitor the equipment's operation and provide ongoing technical support to the customer.
A: Roller conveyor shot blasting machines are suitable for cleaning long steel materials such as steel plates, H-beams, I-beams, channel steel, angle steel, steel pipes, and welded structural components. There are no restrictions on workpiece length, but the width and height must be within the dimensions of the shot blasting chamber channel.
A: Roller conveyor shot blasting machines typically require a pit for installing the shot recovery system. If digging a pit is not feasible on-site, a surface-based recycling solution can be designed. Please confirm with our technical team during the selection process.
A: After shot blasting, the oxide scale and rust on the steel surface are effectively removed, resulting in a uniform metallic luster. The cleanliness meets the standards required for painting.
A: Yes. The conveyor speed can be adjusted according to the workpiece type and cleaning requirements. Slower speeds result in more thorough cleaning, while faster speeds provide higher throughput.
A: Yes. Puhua Heavy Industry can customize the shot blasting chamber channel size, the number and configuration of shot blasters, the conveyor speed range, and the control system functions according to workpiece specifications, production requirements, and site conditions.
