KLRO550 Mobile Road Shot Blaster

Mobile Road Shot Blaster 

Movable Shot Blasting Machine for Concrete Floor and Steel Plate Surface Preparation

The Kholee Blast Mobile Road Shot Blaster is a compact and movable surface preparation machine designed for concrete floors, roads, bridge decks, steel plates, steel bridges, tanks, ship decks and other suitable horizontal surfaces.

Using a high-speed centrifugal blast wheel, the Mobile Road Shot Blaster projects recyclable Steel Shot onto the working surface. The impact removes surface contaminants, concrete laitance, rust, old paint and other unwanted materials while creating a controlled surface profile for subsequent coating, waterproofing or repair.

An integrated abrasive recovery, separation and dust collection system collects used steel shot and surface debris. Reusable steel shot is separated and returned to the storage hopper for recycling, while dust and fine contaminants are transported to the dust collector.

With its portable design, abrasive recycling system and integrated dust collection, the machine is particularly suitable for construction, maintenance and surface preparation projects where the equipment needs to be moved between different working areas.

What Is a Mobile Road Shot Blaster?

A Mobile Road Shot Blaster is a movable surface preparation machine that uses steel shot and centrifugal blasting technology to clean and profile large surfaces.

Unlike fixed shot blasting machines installed in production lines, Mobile Road Shot Blasters can be transported to the work area and operated directly on suitable surfaces.

The machine typically integrates: centrifugal blast wheel, abrasive recovery system, separator, dust collector, air compressor, mobile drive system and electrical control system into one compact machine

This configuration is particularly suitable for surface preparation of concrete floor, road steel deck and tank floor.

Key Features of Mobile Road Shot Blaster

1 Portable & Mobile Design

2 Centrifugal Wheel Blasting

3 Closed-Circuit Abrasive Recycling

4. Dust Collection System

5. Uniform Surface Profile

How Does a Mobile Road Shot Blaster Work?

The machine uses a centrifugal blast wheel to accelerate steel shot onto the surface.

Working Process

Steel Shot → Blast Wheel → Surface Impact → Abrasive Recovery → Separation → Shot Recycling

1. Steel shot enters the blast wheel.

2. The wheel accelerates the abrasive to high velocity.

3. Steel shot impacts the concrete or steel surface.

4. Rust, coating, laitance, mill scale and contaminants are removed.

5. Used abrasive and debris are recovered.

6. The separator separates reusable steel shot from dust and debris.

7. Clean steel shot is returned to the abrasive hopper.

8. Dust and fine particles are transferred to the dust collector.

This closed circuit system allows the abrasive to be continuously recycled while controlling dust generated during blasting.

Frequently Asked Questions

Q1: Can a Mobile Road Shot Blaster be used on concrete floors?

A1: Yes. It is commonly used for concrete floor preparation, including removing laitance, old coatings and surface contaminants and creating a textured profile before coating or repair.

Q2: Can it remove rust from steel plates?

A2: Yes. Steel shot blasting can remove rust, mill scale, oxide and other contaminants from steel plates and prepare the surface for primer and protective coating.

Q3: Can it achieve Sa 2.5?

A3: Yes, a suitable portable shot blasting configuration can be used for steel surface preparation targeting Sa 2.5. The actual result depends on the steel condition, abrasive, blasting intensity, travel speed and project requirements.

Q4: Is portable shot blasting dust-free?

A4: The system is designed as a closed-loop process with abrasive recovery and dust collection. This greatly reduces dust escaping into the work area, although actual dust performance depends on the complete blasting and dust collection configuration.

Q5: What abrasive does a Mobile Road Shot Blaster use?

A5: Steel shot is commonly used. 

Q6: How much concrete can a Mobile Road Shot Blaster clean per hour?

A6: Productivity depends on the working width, blast wheel power, concrete condition, required profile and machine travel speed. Different commercial machines range from small-area equipment to models capable of several hundred square metres per hour.

Q7: Can the machine be used for steel bridge decks?

A7: Yes. Portable shot blasting is suitable for on-site preparation of steel bridge decks where rust and existing surface contaminants need to be removed before protective coating.
