10. Stationary blasting halls
More than 70% of all blasting, descaling and derusting processes are performed stationarily in halls, cabs or special plants. The advantage: the abrasive can be used more often. In principal, the abrasive is used once again in all semi- or fully-automatically operating blasting halls and cleaning units. The abrasive is cleaned thoroughly before using again.
