High-Quality Roller Conveyor Blasting Machines Exporter & Service

Roller conveyor shot blasting machines provide continuous, automated through-feed processing optimized for long, heavy, or flat components like structural H-beams, pipes, and sheet metal plates. Unlike hook machines that process parts in batches, or tumble-belt systems that risk denting fragile components, roller systems feed parts at continuous, regulated speeds, eliminating impingement shadowing and part-on-part impact damage while maximizing hourly production square footage.

For structural descaling and general rust removal, spherical cast steel shot (S280 to S390) or angular steel grit (GL/GH 25 to 40) is typically deployed to strip mill scale and impart a rugged mechanical anchor profile ($R_z$ 50–90 µm) suitable for industrial coatings. For precision fatigue life enhancement or aerospace peening, conditioned cut wire shot, high-hardness cast steel shot (per SAE J444 / AMS 2431), ceramic beads, or glass microspheres are specified to induce controlled compressive residual stresses without generating micro-notches.

Uniformity is achieved through geometric simulation of abrasive projection trajectories. Turbines are positioned at calculated oblique angles (typically between 12° and 35° relative to the conveyor axis) on both upper and lower quadrants of the blast vestibule. This cross-fire orientation ensures that vertical flanges, horizontal webs, and recessed weld corners receive overlapping abrasive exposure during component travel.

Every system conforms to CE Machinery Directives and NFPA guidelines for combustible dust handling where applicable. The filtration units utilize flame-retardant pulse-jet cartridge filters, secondary HEPA safety stages, explosion relief venting doors, and automated differential pressure monitoring. Dual pneumatic seals and interlocking vestibule curtains prevent abrasive leakage into plant work aisles.

Yes. For clients requiring computer-monitored peening and blasting in accordance with AMS 2430 or AMS 2432, our Singapore control engineering team equips the PLC architecture with precision magnetic media flow valves, variable speed closed-loop motor tachometers, and complete Almen saturation logging suites. All process deviations halt operation instantly and are cataloged within exportable audit databases.
