A concrete floor shot blaster cleans, profiles, and strips a floor in one pass. A 200 mm blasting wheel throws steel shot at the surface, and a matched dust collector keeps the work area clean. YG Machinery offers three models: the single-wheel YG-270 and the double-wheel YG-550/600 and YG-850. Working width runs from 270 to 800 mm, and concrete cleaning speed reaches 600+ m²/h. Steel shot use stays near 10 g/m². This guide compares the models, explains shot blasting vs sandblasting, helps you size your job, and shows the next step toward a quote.
Which Concrete Floor Shot Blaster Fits Your Site? 3 Models Compared
Pick by floor area and power supply. The YG-270 suits tight spaces, the YG-550/600 suits mid-size floors, and the YG-850 suits large open areas. All three share a 200 mm blasting wheel and a 400V, 50Hz, 100A power requirement with a CEE socket.

Shot Blasting vs Sandblasting for Concrete Surfaces: Which Wins?
Shot blasting wins on large, flat concrete floors. Sandblasting wins on corners, walls, and detail work. Here is how they differ:
| Factor | Shot blasting | Sandblasting |
|---|---|---|
| Method | A spinning wheel throws steel shot | Compressed air pushes abrasive through a nozzle |
| Best for | Large flat floors and roads | Corners, edges, and vertical surfaces |
| Dust | Matched dust collector captures dust | Open blasting creates heavy dust |
| Abrasive | Steel shot, reused in the cycle | Sand or slag, often used once |
| Coverage | Wide path, steady forward speed | Hand-held, slower on big areas |
Silica sand raises serious dust-health concerns, so check your local rules before you choose an abrasive. When you weigh shot blasting vs sandblasting for concrete surfaces, many crews use both: shot blasting for the open floor and a small sand blasting machine for corners and walls.
How Does a Concrete Shot Blasting Machine Work? 4 Steps
A concrete shot blasting machine throws steel shot at the floor with a spinning wheel, then removes dust through a vacuum. The process runs in four steps:
- Throw. The 200 mm wheel flings steel shot at the surface at high speed.
- Strike. The shot removes paint, laitance, and contamination, and it roughens the concrete.
- Collect. The dust collector pulls dust through the 120 mm or 150 mm connection pipe.
- Advance. The machine walks forward at 0.5 to 33 m/min, so you control the finish.
Use 1.2–1.5 mm steel balls on the YG-270 and 1.5–1.8 mm balls on the YG-550/600 and YG-850. The automatic backflush design clears the filter cores during work, so suction stays steady. Steel shot use stays near 10 g/m², which keeps running costs predictable.

7 Jobs a Concrete Floor Shot Blaster Handles
A concrete floor shot blaster handles seven common jobs:
- Coating preparation. Roughen concrete so epoxy, polyurethane, or paint bonds better.
- Paint and old coating removal. Strip worn layers in one pass.
- Road marking removal. Clear old lines before you repaint with a thermoplastic paint machine or road line marking machine.
- Laitance removal. Take off the weak top layer before you pour or coat.
- Anti-slip texture. Add grip to warehouse floors, ramps, and walkways.
- Steel plate rust removal. Clean steel plates at 15 to 160 m²/h, depending on the model.
- Repair preparation. Open the surface before you use crack filling machines or level it with a concrete laser leveling machine.
For polishing or cleaning without abrasives, consider our portable dry ice cleaning machine as an alternative.
How Long Will Your Job Take? Size It in 3 Steps
Divide your area by the rated hourly efficiency. Follow three steps:
- Measure the area in square meters.
- Divide by the rated efficiency (180, 400, or 600 m²/h on concrete).
- Add time for hard surfaces, thick coatings, and corner work.
Here is an estimate for a 2,000 m² warehouse floor at the minimum rated speed:
| Model | Rated concrete efficiency | Estimated blasting time | Steel shot at 10 g/m² |
|---|---|---|---|
| YG-270 | ≥180 m²/h | About 11 hours | About 20 kg |
| YG-550/600 | ≥400 m²/h | About 5 hours | About 20 kg |
| YG-850 | ≥600 m²/h | About 3.3 hours | About 20 kg |
Real speed varies with concrete hardness and coating thickness. Check your power supply too: you need 400V, 50Hz, 100A with a CEE socket. If your site lacks it, ask us about a matching industrial generator set.
What Does a Road Shot Blasting Machine Price Include? 5 Cost Factors
The price depends on five factors, and we quote once we know your model, power, and destination. Ask every supplier what the road shot blasting machine price covers:
- Model and width. The 270 mm, 550/600 mm, and 800 mm machines sit in different price tiers.
- Motors. Power runs from 11 kW to two 15 kW motors.
- Dust collector. The seven-core and eight-core units differ in capacity.
- Wear parts and steel shot. Ask about spare parts and steel ball supply.
- Shipping and electrical needs. Freight, plugs, and voltage matter for your site.
