A roller conveyor shot blasting machine is a continuous pass-through automatic surface pretreatment device developed for mass long metal workpieces shot blasting. Unlike intermittent hook shot blasters, this whole series adopts linear roller transmission for one-time non-stop blasting, covering steel plates, H-beams, channel steel, round tubes, and various structural parts. All models integrate a blasting unit, an abrasive circulation system, a pulse dust removal system, and an intelligent control cabinet as an all-in-one unit, with a pipe shot blasting machine adding rotary V-shaped rollers to solve the incomplete outer-wall cleaning of seamless steel pipes. The equipment replaces acid pickling and manual grinding in modern production lines, matching both mass assembly lines and small customized metal processing workshops worldwide.
Working Principle of Roller Conveyor Shot Blasting Machine
All YG conveyor shot blasting machine series share a closed automatic circulation working logic based on centrifugal abrasive impact cleaning. Metal profiles or steel pipes are steadily fed into the sealed blasting chamber via adjustable-speed roller groups and move forward at a fixed, uniform speed. Multiple high-power blast turbines rotate at high speed to eject steel abrasives from multiple angles, stripping rust, oxide scale, and welding slag to form uniform rough surfaces for better coating adhesion. Mixed waste abrasives and dust fall to the bottom hopper, lifted by elevator to sorting equipment; qualified steel shot circulates back to turbines while rust dust is absorbed by matched dust collectors. The pipe shot blasting machine’s rotary rollers spin tubes during conveying to realize full 360° blasting without blind spots, and the whole cycle runs fully automatically after one startup without repeated manual loading.

3 Authentic Customer Feedback about Roller Conveyor Shot Blasting Machine
Customer 1: German Steel Structure Factory
Our factory produces bridge and construction steel structures and previously used old hook-type shot blasters with low efficiency and uneven cleaning results. After purchasing a YG roller conveyor shot blasting machine last year, our hourly output increased by nearly 80% thanks to the continuous through-type roller design. The variable-speed rollers never scratch steel plate surfaces, and the matched dust collector keeps our whole workshop clean all day, stably reaching the Sa2.5 surface standard for all finished products. YG’s overseas engineers finished installation and operation training within 5 days of the machine’s arrival. After one year of daily 20-hour continuous operation, the machine only needs simple regular maintenance without major breakdowns, cutting our painting rework rate effectively, and we plan to buy a second unit this year to expand production.
Customer 2: Mexico Pipeline Manufacturing Plant
We mainly manufacture oil and natural gas seamless steel pipes and struggled with incomplete pipe side-wall blasting before cooperating with YG. The dedicated V-shaped rotary roller set of the YG pipe shot blasting machine delivers a full 360° outer wall cleaning effect far better than our previous imported equipment. The multilingual English control panel lets our ordinary workers master all operations within half a day, and the closed abrasive recycling system saves massive steel shot costs every month. The sturdy machine body runs 20 hours daily without overheating or failure, and overseas warehouse spare parts delivery eliminates long downtime risks. This machine has become the core pretreatment equipment of our pipeline production line, and we sincerely recommend YG to all pipe processing manufacturers.
Customer 3: Southeast Asia Heavy-Duty Foundry
We needed a multi-functional roller shot blasting machine to process both structural steel profiles and small hydraulic tubes, yet most suppliers only supplied single-function equipment. YG customized adjustable roller spacing equipment for us, allowing easy switching between flat steel and tubular workpieces without buying extra machines, saving plenty of workshop space and procurement costs. Blasting intensity can be freely adjusted to prevent thin-wall pipe deformation during processing. After 10 months of non-stop production, alloy turbine blades still maintain great wear resistance with rare replacement needs. YG sales staff reply to all our technical questions quickly via video and email, with thoughtful full-cycle after-sales service that greatly raises our finished product qualification rate and factory profit.
