Rolling drum & Rotary barrel shot blasting machine with Tilt-barrel

Rolling barrel or rotary drum shot blasting machines

    Tilt rotary barrel shot blasting machines or rolling drum shot blasting machines, with rotating drums, are particularly suitable for small to medium-sized castings or hot-treated/forged items of small dimensions (brass, plumbing fixtures, and fittings) or delicate parts such as die-cast aluminum.

    The rotary barrel or drum shot blasting machines process is the rolling drum mixes and blasted the pieces from all sides. The interior of the blasting drum is equipped with materials that are abrasives-wearing-resistant. The primary wearing in the high-performance turbines direct blasting zone is made of high-resistant, replaceable reinforced Manganese steel plates.

    The drum shot blasting equipments (Barrel shot blasting machines) have a specific form of the “triangle” strips of the center which cause three-dimensional movement of the pieces, which enables optimal blasting / processing effect of work-pieces.

Features of Shot Blasting Machine:

  • Automatic PLC control with loading and unloading system, batch cleaning and save labor cost;
  • Perfect of finishing consistency of surface cleaning;
  • Specific suits for the solid parts which not afraid of collision during blasting;
  • No pollution for the environmental protection;

Applications of Shot Blasting Machine:

  • Foundry: De-sanding, stripping and preparing for cutting, welding, painting, metallization or surface finishing of bronze and aluminum;
  • Forge: Deburring, removal of laminate and coating, homogeneous surface finish.  
  • Aluminum die-casting: Surface blasting finishing uniform.
  • Customized-made: Surfacing De-sanding, stripping and preparing for cutting, welding, drilling or pior preparing of painting etc.

Characteristics of Rotary barrel Shot Blasting Machine:

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;
  • Top or side installed, optimized shot blast angle and effect ;
  • VFD (Variable Frequent Drive) for motor to adjust of the shot projectile capacity;

  • Shot blasting room design with CAD (Computer-Aided Design) reach of best blasting angle and distance;
  • Blasting room made of strong profiles and 10mm plates;
  • The direct-blasting drum use of upgraded wearing-resistance manganese casting steel with 35-45 HRC;
  • The door opens and close automatically by electricity or pneumatically for sealing;
  • Labyrinth structure to keep the abrasive leak;

3. Loading bucket & Unloading conveyor:

  • The automatic interlock PLC control with shot blasting process;
  • The loading bucket is lifted by electricity (light duty) or hydraulic station (heavy duty);
  • The vibrating conveyor to carry the blasted parts for unloading collection;
  • Manual, mechanic or automatic loading integration continuous belt conveyor aligned with production for loading chamber of batching cleaning;
