What is a concrete shot blasting machine ?

Concrete shot blasting machine eject abrasive at high speed and at a certain angle to road surface to roughen it and remove the residues. Dirt catcher will automatically recycle and clean the abrasive and residues under negative pressure, intact abrasive is recycled and the dust and residues are delivered to collection tank.

The rough surface greatly improved the adhesion strength of the waterproof layer and the concrete base, well guarantee a high quality road.

Cracks also can be clearly found out after treatment to avoid the future possible troubles caused by road quality. We have been over 8 years in manufacturing and designing of high quality concrete shot blasting machine.

 How does a concrete shot blasting machine work?

A valve in placed under abrasive storage tank to control the flow rate of abrasive. Abrasive flow through the valve and reach direction tube by gravity, and then fall into high speed rotating impeller with guidance of direction tube. Abrasive is ejected out at high speed to road surface to roughen it and remove the residues. The abrasive, dust and road residues are then absorbed up forward by high-power dirt catcher which is placed above abrasive storage tank.

Intact abrasive is recycled and the dust and residues are delivered to collection tank. No dirt and no pollution during the whole working process, safe and green. Concrete shot blasting machine is an ideal solution with excellent performance and small investment.

Features of our concrete shot blasting machine:

The machine is made of manganese steel, strong and durable.

• Total working process no pollution appear, all the dust and residues will be cleaned up automatically while working. Don’t need any further clean work. Green and environment friendly.
• Intact abrasive is recycled, no waste.
• Work on dry surface, don’t need other material.
• Include driving system, driving is powered by electricity, no need labor to push or pull. And can start and stop machine at any time if needed.
• High efficiency, treated surface roughness can equal with a new road. Road is flat, no pit appear, no harm to road.

Uses of a concrete shot blasting machine:

1. Improve roughness and friction coefficient of asphalt pavement to improve road adhesion to ensure traffic safety. At the same time, concrete shot blasting machine can remove fuel, oil, etc.. to improve skid resistance performance.

2. Anti-corrosion coating for steel bridge

Concrete shot blasting machine is widely used in anti-corrosion coating process of steel bridge.  All steel bridge include under construction steel bridge and completed steel bridges need to be treated to clean steel plate surface and improve roughness. All process no dust appears, convenient and green.

3. Maintenance of tunnel.

Generally road inside tunnel are cement concrete pavement. While skid resistant performance is a big problem, especially for long tunnel road. Concrete shot blasting machine is the great suitable solution with small investment and simple operation, no dust, no pollution.

4. Maintenance of airport runway

Concrete shot blasting machine can easily remove the tire tracks, marking from cement concrete pavement and asphalt pavement. And at the same time improve road roughness and friction coefficient.

5. Municipal roads maintenance

Concrete shot blasting machine is widely used to roughen and clean the road surface to avoid traffic accident. After 3-4 years working, the road surface gradually become smooth, skid-resistance is bad. Concrete shot blasting machine now is needed to roughen again road surface to prolong road service life, especially for the crossroads.
