Recently, Qingdao KEEJOO Group has successfully delivered its upgraded fully automatic steel plate pretreatment shot blasting machines to multiple enterprises in the steel structure and shipbuilding industries. These machines have won unanimous praise from end users for their consistent rust removal quality, high-efficiency automated production capacity and eco-friendly operational advantages.
Headquartered in Qingdao, Shandong Province, Qingdao KEEJOO Group is a professional full-set shot blasting equipment manufacturer integrating R&D, design, production, sales and after-sales service. Drawing on extensive experience in the surface treatment industry, the company focuses on technological innovation and process optimization for steel plate pretreatment lines, profile shot blasting machines and continuous through-type shot blasting systems. Supported by a mature production system, strict quality control and rich project execution experience, we provide comprehensive customized surface treatment solutions for clients covering shipbuilding, steel structure, wind power, pressure vessel and marine engineering equipment sectors.
The delivered shot blasting machines adopt an integrated continuous roller through-type design. The entire workflow — steel plate preheating, shot blasting rust removal, automatic cleaning, painting and drying — is fully automated in one continuous pass. This effectively addresses industry pain points of traditional manual rust removal, including low efficiency, inconsistent cleaning effect, poor paint adhesion and severe environmental pollution. Fitted with Qingdao KEEJOO’s patented high-efficiency blasting units, the machines deliver uniform impact force and full coverage. All treated workpieces stably meet the industrial rust removal standard Sa2.5, completely removing mill scale, rust and contaminants. This greatly enhances the performance of subsequent anti-corrosion coating and extends the service life of steel materials.
In terms of energy saving, environmental protection and intelligent operation, the equipment is equipped with a high-precision abrasive separation and circulation system as well as a multi-stage pulse dust collector. These configurations ensure high steel shot recovery rate and low abrasive loss, while keeping workshop dust emissions within regulatory limits to meet modern green manufacturing standards. The intelligent PLC control system supports variable frequency speed regulation, one-button start/stop and automatic fault alarms. Operating parameters are adjusted automatically according to steel plate specifications, drastically cutting reliance on manual labor and boosting overall production line efficiency. This enables manufacturers to lower costs, raise output and realize standardized production.
Boasting reliable product quality, sustained technological innovation and a complete after-sales service system, Qingdao KEEJOO’s steel plate pretreatment shot blasting machines are widely deployed across key domestic heavy industry segments and exported in large quantities to global markets including Southeast Asia and the Middle East. Moving forward, Qingdao KEEJOO will remain dedicated to upgrading surface treatment equipment. We will deliver smarter, more energy-efficient and highly stable integrated systems to assist manufacturers at home and abroad in achieving high-quality, green and intelligent industrial transformation.
