Protoblast dual-chamber hopper with independent outlet setup
Many abrasive blasting operations need to switch between different types of media, such as garnet, steel grit, or glass bead. This is especially important for businesses that work with both ferrous and non-ferrous materials. Even small amounts of cross-contamination can cause surface damage, lead to rework, or result in rejected parts, particularly when blasting stainless steel, aluminum, or food-grade components.
If you’re asking how easy it is to change abrasives without risking contamination, Protoblast has the answer.
Why Protoblast Is the Best Option for Easier and Safer Media Changes
Protoblast systems are engineered to make abrasive changeovers fast, clean, and efficient. For operations that need flexibility, Protoblast is the ideal option. Unlike other systems that tend to hold onto abrasive in hard-to-clean areas, Protoblast is built for full evacuation and low-maintenance operation.
Here’s why Protoblast performs better than most abrasive recovery systems on the market:
1. Self-Shedding Oscillating Conveyor
Protoblast uses a fully self-cleaning oscillating conveyor. Once blasting is complete and the room is cleaned down, no abrasive remains on the conveyor. This significantly reduces the time and effort required to switch media and eliminates a common source of cross-contamination.
2. Quick-to-Clear Bucket Elevator
After the conveyor is empty, the bucket elevator also clears quickly. Protoblast includes access doors in both lower corners, allowing any residual abrasive to be removed in minutes. The buckets and the abrasive classifier are designed not to retain any media after shut down.
3. Dual-Chamber Hopper with Independent Outlets
Protoblast offers a dual-chamber abrasive storage hopper with separate outlets for each type of media. Each side feeds its own blast pot. Switching from one abrasive to another is as simple as turning a diverter valve. The cleaned abrasive is directed to the correct side, and the system is ready to go without the need for disassembly.
4. Optional Magnetic Separator for Extra Protection
For industries like medical or food processing where even small traces of steel grit can be a problem, Protoblast offers an optional magnetic separator on the non-ferrous outlet. This captures any stray ferrous abrasive, ensuring pure, uncontaminated blasting media every time.
5. Less Downtime and Lower Maintenance
Because Protoblast systems empty completely and clean easily, customers spend less time on manual cleanup and more time blasting. The result is faster turnaround, reduced labor, and lower maintenance costs.
Changing abrasives with a Protoblast system takes just 15 to 20 minutes. The process is simple, reliable, and designed to protect your surfaces from cross-contamination. Other systems often leave abrasive behind in conveyors, elevators, or classifiers, but Protoblast is different.
From the self-shedding conveyor to the dual-chamber hopper and optional magnetic separator, every part of the system is designed to support clean, fast, and worry-free media changes. If you regularly work with multiple abrasives, Protoblast gives you the confidence and efficiency to switch with ease.
