Our Roller conveyor blast machines

GAMMA roller conveyor blast machine

Continuous pass-through blast machines

Variable speed for processing tailored to individual material requirements

GAMMA roller conveyor blast machines are continuous pass-through units featuring a motor-driven roller conveyor.

The number and configuration of the blast wheels mounted in the blast chamber are optimized to ensure treatment of all surfaces of whatever sheet metal, sections, tubes or structural framing are loaded onto the roller conveyor.

The conveyor variable speed drive lets you strike the best compromise between required throughput and end result based on the condition of the incoming material.

A brushing and blowing unit installed at the exit side of the pass-through enclosure handles removal of any shot left on materials following treatment.
Installation complete with self-cleaning dry-type cartridge filter. Also comes in VERT version to handle sheet metal held vertically.


Rust and scale removal from sheet metal, sections, tubes and structural framing, as preparation prior to painting.

Accessories and optional extras

Blast wheel variable speed drive, digital control panel.

Complete treatment lines

The roller conveyor blast machine can be inserted in line with a painting or coating system.

Turbotecnica designs and builds complete automatic treatment lines including preheating, shot blasting, painting/coating and material feed and transfer equipment.

Version designed for aluminium: GAMMA AL model

The special AL version of the GAMMA shot blast machine has been designed to roughen the surface of extruded aluminium profiles in order to eliminate extrusion defects and reduce the time and costs associated with the subsequent anodizing process. The system is designed to work with very small stainless steel shot.

To ensure removal of shot media from the profiles, a blowing unit has been installed at the exit side of the pass-through enclosure as well as a lifting system hoisting the profiles in question onto the roller conveyor’s unloading section.
