Product Introduction PW2800DA type horizontal movable shot blasting machine is an environmental-friendly product specifically developed for construction and maintenance of various kinds of roads; it can keep dust-free and non-pollution during the construction; and the abrasive can be automatically recycled. The equipment can be used for: water proofing and rough making for concrete bridge deck, and cleaning and rough making for asphalt pavement, increasing the roughness of surface; recovery of anti-skid performance for pavements, tunnels and bridges; cleaning of fatting up and marks; decay-resistant treatment of steel bridge deck; rubber and marks removing for airport pavement.Working PrincipleBy adopting mechanical method, the abrasive (steel balls or sand ) will be cast into working surface at high speed and in a certain angle; the abrasive will impact working surface to roughened by the cast surface and remove the leftovers. Meanwhile, the negative pressure caused by dust collector will clean the abrasive and impurities via airstreams; intact abrasive is automatically recycled, and the impurities and dust will drop into the dust collecting box.Main Performance CharacteristicsMajor components are imported(ABB electric machine, AB soft starter, DELTA converter, SKF bearing); Abrasive-casting room introduces wear-resistant materials to guarantee the service life; wearing parts such as blasting head and oriented jacket are cast in wear-resistant materials, and the service life could reach 20000square meter(Notice: cement concrete pavement).Main Technical SpecificationsType: PW2550DA PW2800DAPower: 29kW 38kWEffective cleaning width: 550mm 800mmCleaning efficiency for concrete surface: above and beyond 300 m2/h 450 m2/hTravel speed: 0.5 25square meter/min 0.5 20square meter/minDust reclaiming: Blowback dust collector XC0408D Blowback dust collector XC0408DWalking Style: Horizontal, Self-propelled Horizontal, Self-propelledAppearance Dimensions (Length X Width X Height): 2050×720×1460mm2150×980×1450mmWeight: 595kg 770kg Type: PW2550DA PW2800DAPower:29kW 38kWEffective cleaning width:550mm 800mmCleaning efficiency for concrete surface: above and beyond 300 m2/h 450 m2/hTravel speed: 0.5 25square meter/min 0.5 20square meter/minDust reclaiming: Blowback dust collector XC0408D Blowback dust collector XC0408DWalking Style: Horizontal, Self-propelled Horizontal, Self-propelledAppearance Dimensions (Length X Width X Height): 2050×720×1460mm 2150×980×1450mmWeight: 595kg 770kg
