The road mobile shot blasting machine applies for pavement of concrete road and railway.
Road railwany bridge vulnerable to rain erosion,the corrosive effect of the rain on the birdge showed:rainwater infiltration caused damaged in concrete base environment,the lose of calcium,will result in erosion of concrete,steel rust ,strength reduction,resulting in reduced the service life of bridge.Especially in north area,temperatures below 0 ℃ in the winter,freeze-thaw damaged the concrete surface ,exacerbate the corrosion rate of steel.In the past,bridge surface pavement listed undefended basic aqueous layer,it relies mainly on the aspect of slope and drainage discharge system,some bridges set waterproof layer,but the quality below standard,that must will lead the surface of birdge appears water seepage, off pavement, alkali - aggregate reaction, steel corrosion caused severe damage to concrete spalling and other problems.

Road mobile shot blasting machine is produced by QINGDAO KNNJOO MACHINE INC which is designed for a variety of construction and maintenance of road construction and the development of environmentally friendly products,during the construction work,it can be done in clean ,non-polluting,and pellets can be automaticaly recycled.The machines apply: roughening concrete bridge deck waterproofing,cleaning and roughening asphalf pavement,to increase the surface roughness; recover the skid resistance of road,tunnels and bridges;asphalt pavement weeping cleanup,clean the flag line;steel deck anti-corrosion coating process;rust blaster cabin deck surface;removal the glue and line of the airport road；shot blasting oversized steel surface roughening, water treatment and other indrustrial coating plant floor cleaning,roof surface. 

KNNJOO Shot blasting machine is an environmentally friendly, efficient and concrete, asphalt, stone, steel surface treatment machinery. By throwing the first high-speed operation of 0.5-2.0 mm diameter after accelerating cast steel shot hit the surface to be treated, clean the surface of the deposits, and to a certain roughness, directly to clean up cleaning purposes or for the next pavement prepare grassroots preparation. Waste generated is automatically collected into the cleaning device supporting the operation of the whole process without any pollution and emissions, the treated surface is no residue, without further treatment for a variety of cleaning and pretreatment of the surface, in particular suitable for highway maintenance, bridge maintenance, airport maintenance and other areas, particularly noteworthy things through shot blasting machine processing surface, can meet the standard SA2.5 / 3, to meet the special steel surface processing requirements.

Shot blasting clean equipment：
Uniform surface roughness;
Completely removed from the sand and floating pulp;
100% "a surface" exposed bone, but it does not remove the close bond
Time construction, do not need to clean up late;
Construction and high efficiency;
Low equipment operating costs;
Early exposure to concrete defects,
Open the concrete pores;
Construction process no dust, no environmental pollution
Construction, high efficiency, 8 hours a day cleaning efficiency can reach 1,500 to 2,000 square meters.
Simple, 2-3 people can operate.

 Supplier promise the name, model, specification and quantity comply with technical protocol,
