DS210 Portable Shot Blaster

The DS210 is an affordable, 220V portable blast cleaning system designed for versatility. It is ideal for completing small-to-medium jobs and serves as an excellent complementary unit for larger projects, specializing in edge work and hard-to-reach areas.

Key Features & Performance:

High Efficiency: Cleans and profiles surfaces in a single pass, removing up to 3mm of material with a 210mm blast pattern.
Versatile Media: Compatible with shot sizes from S-170 to S-390.
Wide Application: Perfect for small floor areas, tight spaces, balconies, garage floors, basements, and pool decks.
User-Friendly: Lightweight and portable design ensures easy operation in one simple step.

The blast container can also be fully configured to your specifications and wishes so that your products can be optimally processed, a number of possible options:

How the DS210 Works

The mechanical operation of the DS210 is straightforward. When the shot lever is squeezed, it pulls a cable that opens the shot valve, releasing abrasive from the hopper. The shot travels through the valve and feed spout into the blast wheel, which is enclosed within a control cage. A 220V right-angle motor then spins the blast wheel at high speed, throwing the shot through an opening in the control cage directly onto the concrete surface.

The high-velocity impact fractures the concrete, generating dust. Upon striking the surface, the shot rebounds into the blast housing. Through a combination of this rebound effect and integrated vacuum suction, the mixture of shot and dust is drawn into the system. Because the shot is heavier, gravity causes it to fall back into the hopper for continuous recycling. Meanwhile, the lighter concrete dust is extracted through a duct hose and deposited into the dust collector’s bin.

Wear Parts

DS210 Shot Blaster Exploded View：

The DS210 contains components that are continually exposed to high-velocity steel shot. The prolonged exposure to high-speed shot and concrete dust causes these parts to deteriorate. Therefore, operators should regularly inspect the wear parts of the DS210 and replace them as necessary based on their condition.

Shot Blasting Machine Wear Parts Inspection Schedule

Recommended inspection intervals for critical wear components in shot blasting equipment. Actual intervals may vary depending on operating conditions, abrasive media type, and machine model. Always refer to your specific DISA machine operation manual.

Part	When to Inspect	Evidence of Wear
Shot Hopper	30 hours	Warping or thin spots
Feed Spout	50 hours	Thin spots
Blast Wheel	10 hours	Blades deteriorated > 50%
Control Cage	10 hours	Deteriorated edges
Blast Wheel Hub	10 hours	Missing pins / deterioration
Liners	10 hours	Warping, holes, deterioration
Blast Housing	50 hours	Thin sections or other deteriorations

Note: This schedule is a general guideline for preventive maintenance. More frequent inspections are recommended for high-production environments or when using aggressive abrasives. Replace parts immediately upon detection of significant wear to avoid secondary damage to the machine.

Frequently Asked Questions

Why is setting the proper blast pattern so important?

Setting the correct blast pattern is critical because an improper or unevenly distributed pattern will result in excessive blasting on either the left or right side of the machine, leaving shadows or "track" lines on the surface. Since the ideal pattern must be determined through trial and error, careful adjustment is essential.

How do I properly test and set the blast pattern?

Please follow these steps to perform the test:
First, verify that the blast wheel is rotating in the direction indicated on the blast housing.
Place a sheet of steel approximately ¼” thick under the machine, open the shot valve fully, and blast for about one minute.
⚠️ Note: Do not move the machine during this time.
After one minute, shut down the machine and inspect the blast pattern on the steel sheet. The "hot spot" should be centered across the width of the blast.

What should I do if the "hot spot" is not centered?

You can adjust the position of the "hot spot" by making small increments of rotation to the control cage:

Rotate the control cage counterclockwise: The "hot spot" will move to the right.
Rotate the control cage clockwise: The "hot spot" will move to the left.
Ideal Position Reference: Visualizing a clock face, the opening of the control cage should be set at approximately 10:30 (leading edge) and 8:30 (trailing edge).

What if I still cannot achieve the desired blast pattern after adjusting the control cage?

There are four main factors that affect the blast pattern, with the control cage setting being the most crucial. If adjusting the cage does not resolve the issue, troubleshoot the remaining factors in this order:

Check if the shot size being used is appropriate.
Verify that the wheel rotation direction is correct.
Inspect the wheel kits for wear, and replace them if necessary.

What precautions should I take when adjusting the control cage?

The optimal control cage setting varies depending on the size of the steel shot being used and the type of surface being blasted. When adjusting, make only small increments at a time until the desired blast pattern is achieved. Once properly set, the blast pattern should remain consistent.
