Wire single pass shot blasting machine

Ⅰ. Equipment usage

This machine is a special equipment for wire cleaning. It uses the shot blasting process to remove the oxide scale on the wire surface. After shot blasting, the rust removal level of the entire surface of the workpiece reaches Sa2.5. Compared with the pickling treatment, it is economical, environmentally friendly and efficient. Features.

The equipment adopts a unique built-in shot blasting device, which greatly improves the production capacity of the equipment. The reasonable arrangement of the shot blasting device allows the inner and outer surfaces of the wire to be effectively hit by the projectile. The whole machine is controlled by PLC, fully automatic operation is convenient and reliable

Ⅳ.shot blasting process and working principle

1. The working principle of shot blasting

 According to the characteristics of the wire, the machine adopts 4 high-efficiency built-in shot blasters installed inside the chamber, and the wire is shot blasted at a projectile speed of 78 m/s. The machine also passes the pill and slag separation system, high-strength

High temperature resistant belt hoist, two-stage long fiber polyester filter cartridge purification and dust removal system (inertia + filter cartridge), automatic + manual man-machine interface electronic control system, so that the workpiece can meet the requirements of efficient automatic shot blasting.

2. The projectile cycle sequence:

Projectile storage →             flow control →                     shot blasting cleaning

↑                                                                                                  ↓

(Recirculation) Pill storage bucket ← Pill slag separator ← bucket elevator vertical lifting

3. Dust treatment sequence:

Shot blasting chamber/separator dust → inertial sedimentation chamber → filter cartridge dust collector → discharged into the atmosphere
