Mechanical Recovery System – Screw Conveyor & Bucket Elevator

Mechanical Recovery System for Abrasive Blast Room uses screw conveyors and bucket elevator to convey abrasive residues into recovery system. The ideal solution for maximizing operator performance, care and maintenance of system components. System is suitable for large or small rooms, and offers flexibility in terms of recovery speed and floor layout.

This recovery system can handle all types of abrasives available on the market today, including heavy media such as aluminum oxide, steel shot, and steel grit. With media recovery capacity of over 10,000 lb. per hour and unlimited recovery pit length or number, this system is designed for maximizing operator productivity while simplifying room cleaning after blasting operations.

Dust collectors associated with this system are DCM3000 to 50000 Series.

ISTblast offers various types of recovery floors which will be adapted according to your available production space and budget. Either for a surface installation or excavated, dimensions can vary from 4 feet in length for the compact installations, and to more than 40 feet for high output industrial facilities. The configurations are practically infinite!

The shallow and space saving over the floor design, is easy to install and requires limited maintenance. A 17” floor excavation is sufficient for existing floors. The system can also be installed on a concrete floor or on any other permanent or temporary floor.

We manufacture a complete line of Recovery Systems to accommodate sandblasting facilities constraints, and these systems are compatible with our equipment, with other manufacturers’ equipment, and even for self-fabricated facilities. The fundamentals behind an effective Recovery System is to Recover, Recycle and Reuse the abrasive. (3R).


The concept of recycling abrasives allows the user to achieve substantial savings in abrasive consumption while protecting the environment from harmful sandblast dust. For example, the cost of steel shot is of approximately 10 times superior compared with the cost of any non-recyclable media. However, steel shot abrasives can be recycled and used up to 100 times compared to only once with the standard media, which makes it a lot cheaper per usage compared to non-reusable abrasives.

The non-recyclable sandblasting abrasives are not expensive to purchase but they can only be used for one sandblasting cycle. Because of their fragile molecular structure, they deteriorate quickly while generating harmful residual dust and substantially reducing the visibility of operators.
