Automatic Shot-Blasting Machines

Vertical Roller Table | Model LAMI-V

Shot-Blasting Process: Continuous

The LAMI V model, with vertical rolling tables for feeding and extracting elements, is the most efficient and effective solution for shot-blasting sheet metal (steel plates). Also allows the shot-blasting of steel profiles.

The steel plates are placed on the rolling table with variable speed, which continuously transports into the projection chamber where a set of electrically driven and properly positioned centrifugal turbines project at a speed of 3.000 rpm a mixture of spherical and angular steel grit against the plates, guaranteeing a uniform shot-blasting pattern (e.g. SA 2,5) throughout the whole plate.

The roller tables are hydraulic driven (horizontal and vertical position) making the sheet placement process more efficient. The table is in horizontal position to receive the plate, going to vertical position to enter into the shot-blasting chamber.

The steel grit projected against the plate falls by gravity, eliminating the need for a cleaning chamber after the projection chamber.

The dust resulting from the shot-blasting process is extracted by a fan into a filter cabinet.

The automatic shot-blasting process takes place in a closed circuit. The projected steel grit is collected by a screw conveyor, installed at the bottom part of the machine, up to the elevator bucket that transports it into the recuperator hopper, mounted over the machine and distributes it within the centrifugal turbines.

Depending on the size of the parts to be shot-blasted, the projection chamber, the number of turbines and other elements are defined.

  • Projection chamber built with anti-wear material.
  • Centrifugal Turbines of high performance and endurance for steel grit projection. Models from 7,5 kW up to 18,5 kW.
  • Bucket elevator.
  • Recuperator hopper with respective steel grit distribution valves with pneumatic adjustment.
  • System of recovery and treatment of steel grit, maintaining a suitable particle size, eliminating impurities
  • Dust extraction by fan into filter cabinet with automatic sequencer cleaning of filter cartridges.
  • Vertical rolling table for feeding and extracting the steel plates with adjustable speed. The rolls in the projection chamber have suitable heat treatment and protection labyrinths over the bearings that support the rolls. The roller tables are hydraulic driven, allowing to have horizontal and vertical position.
  • Variable speed during shot-blasting process of the elements, allowing different shot-blasting patterns.

Horizontal Roller Table | Model LAMI-H

Shot-Blasting Process: Continuous

The LAMI H model, with horizontal rolling tables for feeding and extracting elements, is the most efficient and effective solution for shot-blasting steel profiles and steel structures.

The profiles and structures are placed on the rolling table with variable speed, which continuously transports into the projection chamber where a set of electrically driven and properly positioned centrifugal turbines project at a speed of 3.000 rpm a mixture of spherical and angular steel grit against the material, guaranteeing a uniform shot-blasting pattern (e.g. SA 2,5) throughout the whole plate.

After the projection chamber, the shot-blasted parts enter into a cleaning chamber in which a linearly positioned rotary brush and high-pressure blowers remove the powder and some of the steel grit deposited on the parts.

The dust resulting from the shot-blasting process is extracted by a fan into a filter cabinet.

The automatic shot-blasting process takes place in a closed circuit. The projected steel grit is collected by a screw conveyor, installed at the bottom part of the machine, up to the elevator bucket that transports it into the recuperator hopper, mounted over the machine and distributes it within the centrifugal turbines.

  • Dust extraction by fan into filter cabinet with automatic sequencer cleaning of filter cartridges.
  • Horizontal rolling table for feeding and extracting the steel profiles and steel structures with adjustable speed. The rolls in the projection chamber have wear protection and also protection labyrinths over the bearings that support the rolls.
  • Variable speed during shot-blasting process of the elements, allowing different shot-blasting patterns.

Suspension System | Model CARPENFER

Shot-Blasting Process: Continuous

The CARPENFER model, in closed circuit by carousel system for feeding and extraction of parts, is the ideal solution for shot-blasting parts with complex geometries, guaranteeing high productivity rates.

The parts to be shot-blasted are suspended in hooks coupled to the variable speed carousel system, which continuously conveys them to the projection chamber where a set of electrically driven and properly positioned centrifugal turbines project at a speed of 3.000 rpm a mixture of spherical and angular steel grit against the parts, guaranteeing uniform shot-blasting pattern (e.g. SA 2,5) throughout the whole parts.

The pieces can also be rotated inside the projection chamber.

After the projection chamber the shot-blasted parts pass through a cleaning chamber composed of high-pressure blowers that remove the dust and the steel grit deposited on the parts.

The dust resulting from the stripping process is extracted by a fan into a filter cabinet.

The automatic shot-blasting process takes place in a closed circuit. The projected steel grit is collected by a screw conveyor, installed at the bottom part of the machine, up to the elevator bucket that transports into the recuperator hopper, mounted over the machine and distributes it within the centrifugal turbines.
