Closed circuit portable movable shot blasting machine for steel plate

Road surface shot blaster;Granalladora de Portátiles para concreto pisos; Granalladora para chapa de acero;

    The Closed-circuit movable shot blasting machine for steel plate is a new small, portable, and mobile shot blaster, mainly used to increase the roughness and friction coefficient of rust removal on the surface of large steel plates and bridge deck floor etc.

    During the operation of the portable road-surface shot blaster, by controlling and selecting the particle size and shape of the shot abrasive, and adjusting and setting the walking speed of the shot blasting machine, the shot flow rate is controlled to obtain different shot strengths and different surface treatment effects.

    Movable Shot blasting machines can be divided into hand-push type, vehicle-mounted type and white line type according to the walking mode. With walking motor, it can walk independently, theoretically climb 30%, can forward and reverse functions, three-phase asynchronous, 380v/480v, 50Hz/60Hz.

2. Steel-plate Shot Blasting applications:

  • Anti-corrosion coating of steel bridge deck
  • Shot blasting machine for steel plate

    The application of shot blasting technology in the anti-corrosion coating of steel bridges has been fully affirmed in our country. Most of the bridges under construction and already built choose to use the shot blasting process for surface cleaning and roughness treatment before anti-corrosion primer or other sprayings. The use of shot blasting to treat steel bridge decks can meet the requirements of SA2.5/SA3 steel plate cleanliness, and can control the roughness to meet coating requirements, and the entire process is dust-free and easy to move.
