Shot blasting machine for Bars, Suck Rods, rebars

    Shot blasting machine for bars, Suck Rods are designed to small diameter of tubes and pipes, round bars, rebars, drill rods, round sections, thin gas steel bottles, and other cylindrical elements external surfaces treat tubes and cylindrical workpieces (cylinders, tanks, etc.) of various  lengths at various transport speeds in a continuous process.

    Featuring a rollers or the skew conveyor arrangement, the bars shot blasting machines are equipped with a motor-variable-frequency-driven inverted through the shot blasting machine for suck rods on a conical cylindrical conveyor or on a conveyor while rotating around rollers’ longitudinal axis, which is a condition for evenly blasted surface standard.

    The automatic bars shot blasting machines, also for tubes, cylinders, and long tanks; may operate individually or be built in an existing transport system of highly productive lines for basic paint application, including a drying chamber, automatic painting chamber, and drying tunnel.

    Standard equipment includes PLC, HMI display, automatic or manual mode, automatic start-up of shot wheels, working-hour time counter, roller conveyor variable frequency drive (VFD), etc.

Features of Shot Blasting Machine:

  • Automatic PLC control, save labor cost
  • Perfect for finishing uniform surface cleaning
  • Continuously feed for pipes, tubes, cylinders, etc.
  • No pollution for the environmental protection

Applications of Shot Blasting Machine:

  • Cylinder: Remove rubber, rust, and stain for a repaint or recoating; 
  • Pipes: Surface cleaning for painting, coating or drilling, welding, etc.
  • Bars, Suck rods: Remove dust, rust, and stain for a repaint or recoating; 

Characteristics of Continuous Shot Blasting Machine for Bars, Suck-Rods:

1. High efficient of Shot wheel Turbines

  • Compact shell structure, longer lifespan of blades, lower maintenance;
  • Upgraded wearing-resistance with low working noise & vibration;
  • High-speed blasting capacity with more recycle abrasive using;
  • Optimal blasting angle, velocity and energy-saving;
  • 360 degrees of coverage or lower postion shot turbines installed;
  • VFD (Variable Frequent Drive) for motor to adjust of the shot projectile capacity;

  • Labyrinth structure to keep the abrasive leak;

3. Skew conveying system:

  • The roller conveyors with mangeness liners for longer lifespan;
    • Horizontal continuously rollers for the multi low-diameter pipes displayed at the same time;
    • Screw rollers for big-diameter pipes, one piece per time;
  • Bearing support with the labyrinth shape prevents leaking of the steel media;
  • Standard capacity is 1,000kgs per meter;
  • VFD (Variable Frequent Drive) for motor to adjust of the input & output feed speed;
