Shot blasting with robot
Clemco Denmark is a leader within the supply of very durable and advanced robotic blast cleaning systems for larger steel structures. The industries within off-shore and wind turbines have been our working field for many years.
CLEMCO ROBOTIC BLAST MACHINE 300 L DUAL CHAMBER
The Clemco 300 liter blasting unit is a traditional blasting container, but with additional electrical and pneumatics components made for robotic blasting. The timing of the cycles between the blasting and loading is controlled by a PLC. The tank needs to be loaded with abrasive blasting media every 20 minutes of operation.
The air supply is prepared with 2” piping for the main air valve ensuring the pop-up system in the chamber to close faster which means less pressure loss. The valves ensure that the pressure is maintained constantly in the shot blasting system.
The blast cleaning process starts and stops by the robot, which is controlled in the blasting program.
On the user panel you can start and stop the blasting process to test the automatic blasting equipment.
The amount of grit coming out of the nozzle is regulated on the abrasive valve on the bottom outlet of the blasting machine. The blasting pressure is controlled by the robot and can also the controlled on the operator panel at 2 set-point values. In practice the equipment can be installed with one 19mm venturi nozzle or two 19mm venturi nozzles. With one 19 mm nozzle the approx. cleaning time is 1,5 m2/min to SA 2½ with the Clemco Denmark robot solution. The roughness can be from 90-100μ to 120-150μ depending on grit size and abrasive material. Normally we will recommend a work mix of steel grit for robotic abrasive cleaning and steel surfaces.
