Abrasive material recovery in a sandblasting booth

The sandblasting phase generated material dispersion that was difficult to manage using traditional methods:

• Material loss: continuous dispersal of abrasive material both in the work chamber and in the pit below.
• High costs: abrasive material is an expensive component that heavily impacts the production budget.
• Reduced efficiency: manual recovery operations were inefficient, slow, and required excessive labor.
• Need for circularity: urgent need to reintroduce the material into the production cycle to reduce waste.

DHV COMPACT 22 HOPPER

Delfin installed a DHV Compact 22 Hopper high-vacuum system, specifically designed for handling heavy materials:

• Rotary lobe pump: ensures consistent performance and high vacuum power even for densest materials.
• Full automation: automatic filter cleaning system that eliminates the need for manual intervention by the operator.
• Smart discharge: integration of an electro-pneumatic guillotine valve for direct discharge of material into big bags.

Cost savings and optimized process

• Economic recovery: Immediate savings thanks to the systematic reuse of the vacuumed abrasive material.
• Work environment: optimal cleanliness of the cabin and pit, resulting in improved safety conditions.
• Flow automation: discharge of the collected material at a designated point, ready to be reintroduced into the cycle.
• Zero manual maintenance: autonomous management of filtration systems, minimizing the time spent on machine maintenance.
• Steel mill efficiency: seamless integration into a heavy industry setting with machinery built to last.
