Floor Shot Blaster

Floor shot blaster is a kind of road construction tool and equipment like mini roller compactor, line marking machine, power trowel machine, and crack sealing machine which can clean up the floating slurry and other contaminants like dust and paint at one time, and can roughen the road surface greatly improving the adhesion strength of waterproof layer and concrete base so that the waterproof layer and bridge deck can be better combined. Meanwhile, the cracks of concrete can be fully exposed after the working of portable shot blasting machine, which plays a preventive role. A shot blasting machine can be used in concrete floor and steel floor. With excellent performance, floor shot blaster for sale in Henan Yugong has been well welcomed by customers.

How Shot Blasting Machine Works?

The portable shot blasting machine projects a large number of small steel balls onto the surface of the road at a high speed and a certain angle by mechanical method. Small shot blasting machine enables the shot materials to impact and roughen the road surface while removing the laitance, paint, old coatings, dirt and other contaminants. At the same time, the negative pressure generated by the precipitator of the concrete floor shot blaster will recover the shot material and dust. After the cleaning of the air flow, the intact shot materials will be automatically recycled, and the dust will also fall into the dust collection box.

Working Efficiency of Floor Shot Blaster

If the floor shot blasting machine works in concrete or cement floor, it’s working efficiency can be 300-600m2/h. For steel plate, if the rust-removal grade is SA2.5, the speed of the small shot blasting machine is about 4 meters per minute. SA3 is about 3m/min. And the processing area of SA2.5 is approximately 100-180 square meters per hour.

The portable shot blaster in Yugong mainly consists of a control cabinet, a rebound high-pressure chamber, shot blasting motor, walking handles, feed inlet, dust collector connectors, separating system, walk driving system, etc.

In control cabinet, you can find main switch, motor light switch of shot blasting motor,  ammeter,  electric instructions, emergency stop switch, walking switch, and walking speed switch, which makes the operation easy and high-efficient. Shot separating system mainly controls the separation of shot material and dust. The walk driving system is driven by a motor. More detailed parts please contact us, and our sales manager will present to you clearly.

More importantly, we have matched dust collector with the floor shot blasting machine. The dust collector matched with the concrete floor shot blasting machine uses three-way back-blowing to clean the dust, and to ensure the smooth circulation of the dust collector, it adopts the pulse valve and the sequential control principle. In addition, the vacuum cleaner uses poly raw grease dedusting hose to make sure the connection is wear-resistant and reliable. And the filter paper in this dust collector is imported to strengthen the good dust removal result and long-term stable service.

Five Typical Applications of Concrete Floor Shot Blaster

1. Asphalt road. Small shot blasting machine can be used to improve the roughness and friction coefficient of asphalt road so that the adhesion of the road can be improved, which ensuring a safe driving. Meanwhile, fuel oil, engine oil, and other contaminants can be removed, which can increase the anti-sliding performance of the road.

2. Steel structure bridge anti-corrosion coating. When constructing a bridge, the floor shot blasting machine plays a very important role in the cleaning and roughening of the bridge surface to resist corrosion.

3. Tunnel maintenance. In tunnels, the surface generally is concrete cement, and small shot blaster is a good way in dealing with the tunnel surface because it is easy in operation, low in cost, good in performance, and free of pollution.

4. Preventive maintenance of airport runways. A portable shot blaster can easily remove the traces and markings on concrete and asphalt runways. And it can also increase the roughness of the airport runways surface.

5. Municipal roads and paved roads. Shot blasting machine is widely used in road pavements to remove the markings in the road surface. For traffic intersection, the road surface can be roughened to increase the roughness and friction.
