The bridge deck shot blasting machine is mainly used for waterproof construction on railway bridge decks, surface roughening of highway bridge and tunnel pavements, epoxy floor surface roughening, etc. The product is widely applied in concrete shot blasting, bridge shot blasting, steel plate shot blasting, steel box girder bridge shot blasting, high-speed railway shot blasting, airport runway rubber removal, increasing friction area on highways and airports, ship shot blasting, waterproof construction shot blasting, industrial floor shot blasting, highway marking line cleaning, large oil storage tanks, and roughening the decks of large warships and ships to improve adhesion. Our company can design and produce various customized road shot blasting machines according to customer needs to meet the requirements of different industries.
The bridge deck shot blasting machine utilizes an electric motor-driven shot blasting impeller that generates centrifugal force and airflow during high-speed rotation, achieving a shot blasting rate of 200Kg/min. The shots enter a high-speed rotating distributor wheel and, under centrifugal force, are ejected into a directional sleeve. After passing through the directional sleeve (which controls the direction of the shot blast), they are picked up by high-speed rotating blades and accelerated along the length of the blades until ejected. The ejected shots form a fan-shaped stream at a speed of 120m/s, hitting the pavement or steel surface. Depending on the type of abrasive, the penetration depth can reach 1-5mm, creating a uniform texture that cleans and reinforces the working surface. The shots, along with dust and impurities, then pass through a rebound chamber to the top of the storage hopper. A high-power dust collector separates the shot from the dust via a separator above the storage hopper. The shot enters the storage hopper for reuse, while the dust is conveyed through dust removal pipes to the dust collector. Through filter separation, the dust settles in the dust hopper and on the filter surfaces. An automatic reverse-pulse dust collector uses compressed air to periodically clean each filter. Finally, inside the machine, airflow from an accompanying suction cleaner washes the shot and separates the impurities, allowing the shot to be recycled. The shot blaster is equipped with a dust collector, enabling pollution-free construction, improving work efficiency, and protecting the environment.
