2018 OMSG CWB 850 4T L

The OMSG CWB 850 4T L conveyor belt shot blasting machine, manufactured in 2018, is a highly reliable and high-performance industrial solution designed for cleaning, deburring, surface preparation, and finishing of metal components. Engineered to ensure consistent processing quality and continuous production, this machine stands out for the robust construction typical of OMSG equipment and for its advanced level of automation, making it suitable for both batch production and intensive industrial applications.

The machine is equipped with a steel mesh conveyor belt with a useful working width of 850 mm and standard mesh size of 50 x 80 mm, allowing efficient processing of components with different shapes while maintaining stable and uniform transport.

The conveyor speed is adjustable from 0.5 to 4.5 m/min, enabling operators to adapt the blasting cycle according to production requirements and the desired surface finish.

The maximum workpiece height is 500 mm, providing excellent versatility for structural steelwork, mechanical manufacturing, and treatment of medium to large metal parts.

The blasting system is powered by four SG360 turbines rated at 7.5 kW each, designed to deliver uniform abrasive distribution and high impact energy for effective surface treatment.

Turbine speed is automatically controlled via inverter, ensuring precise process regulation while optimizing energy consumption. Four dual-flow abrasive control valves (type 2P) allow quick adjustment of shot flow rate depending on material type and finishing requirements.

Machine operation is managed by a Siemens S7-1200 PLC control system, a modern and reliable solution that guarantees ease of use, accurate parameter management, and simple integration into automated production lines.

This control system improves process repeatability while reducing setup times and maintenance interventions.

Special attention has been given to dust management and operational safety through a continuous-duty automatic filtration unit equipped with six self-cleaning cartridges, an explosion relief panel, and a fan outlet silencer. These features contribute to a safer, cleaner, and more efficient working environment aligned with modern industrial standards.

The machine also includes several structural and functional upgrades aimed at improving durability, maintenance accessibility, and long-term reliability. These modifications include a closing plate for burr recovery drawer extraction with a single hinged door, rerouting of rotary screen waste discharge toward the outlet-side conveyor, a reinforced lower pulley replacement cover with increased thickness, and a strengthened outlet-side machine wall.

With a total installed power of 47 kW and overall condition described as excellent, this used shot blasting machine represents a ready-to-operate solution for companies seeking a dependable, productive, and technologically updated system capable of delivering high-quality metal surface finishing with continuous operational performance.
