Noise level: ≤ 85 dB(A)

Machine size (W × D × H): 4730 × 5070 × 6520 mm

Mains: 400/690 V, 50 Hz • Control voltage: 24 V DC

Control & Automation

PLC (NX platform) with touchscreen HMI and remote service access. Up to 99 programs with per-job settings: blast time, turbine speed, hook rotation and speed, swing angle of turbine block, servo abrasive flow per wheel, automatic conveyor start/stop. Diagnostics and full interlocking on doors and motions.

Wear Protection & Build

Blasting chamber lined with XAR500 wear plates (5 mm) and manganese steel X120Mn12 in formed/high-wear zones; replaceable rubber in impact areas. Wheel internals (blades, cages, liners) made from tool steel 1.2379 / X153CrMoV12 (~62 HRC). Heavy welded turbine block housing. Service platform with safety gate and Total Stop.

Abrasive Circuit

Designed for steel shot S330 (initial charge about 1.5 t). Elevator → air separator → shared hopper loop; magnetic/air cleaning maintains media quality. Servo dosing to each wheel ensures uniform intensity and reduced consumption.

Extraction & Filtration

CIPRES CARM dust collector, 7.5 kW fan, automatic back-draft flap; ducting includes automatic valve for cabin purge at cycle end.

Handling System

Powered monorail with adjustable speeds; servo-driven hook rotation and lift; pneumatic diverter switch; two 1.1 kW hoists. Timed sequence allows loading the next batch while blasting.

Applications
Redpfx Abjxpiw Uewjw

Forgings, castings, welded structures and general steel fabrications—surface preparation before painting, galvanizing or coating with high throughput and repeatable Sa 2½–3 results.

Key Advantages

5 wheels for high coverage and speed • PLC plus servo precision • XAR and manganese lining for long service life • 12-ton EU build • Low noise ≤ 85 dB(A).
Available for inspection on request via the platform.
