Ship anchor chain shot blasting machines and mine chain shot blasting machines are medium and small-sized shot blasting cleaning equipment specially developed for surface cleaning of anchor chains. They are mainly used to remove surface oxides and surface attachments of anchor chains. Compared with other similar anchor chain cleaning equipment in China, it has the advantages of high productivity, high separation quality of steel shot and dust, good cleaning effect and low failure rate.
The ship anchor chain shot blasting machine and the mine chain shot blasting machine are designed and manufactured by the company based on the equipment performance requirements proposed by users. They can clean the φ22-φ150 type anchor chains in one go. It cleans the oxides and surface attachments on the surface of the anchor chain by ejecting countless high-speed moving shot streams onto the surface of the anchor chain, and effectively enhances the fatigue strength and corrosion fracture resistance of the anchor chain by causing plastic deformation on its surface.

Main components and structural features of the mine chain shot blasting machine
1. The ship anchor chain shot blasting cleaning machine mainly consists of a shot blasting cleaning chamber, a sealing chamber, a hoist, a separator, a screw conveyor, a shot blasting machine assembly, a shot collection system, a hoist platform, inlet and outlet guide wheel groups, a shot supply system, a foundation, a dust removal system, an electrical control section and other components
2. The shot circulation and separation system of the mine chain shot blasting machine includes the following functional components: elevator, separator, screw conveyor, shot control system, shot blasting machine assembly, etc. The mixture of shot and slag lifted by the bucket elevator. Separated by a spiral separator, it is evenly distributed along the entire length of the separator. By adjusting the weight of the separator, the mixture is evenly distributed in a flow curtain shape. The mixture then enters the elevator and is lifted to the separator for separation, and is used in a cycle in sequence.
3. Dust removal system: Qualified shot enters the shot silo. The shot in the shot silo enters the shot blasting machine through the shot supply gate. The shot and slag mixture after shot blasting is conveyed through the cleaning chamber and the screw conveyor. The dust removal system is composed of a bag filter, a centrifugal high-pressure fan, a dust collector motor, pipelines, etc. The high-pressure centrifugal fan is used to draw air into the chamber to create a certain negative pressure, preventing the dust generated during operation from floating outside the chamber. As a result, the dust concentration around the equipment does not exceed 10mg/m ³, meeting the national environmental protection standards.
4. Anchor Chain Conveying System The anchor chain conveying system consists of four parts: the inlet wheel set, the guide wheel inside the chamber, the outlet guide wheel, and the outlet driving wheel. The operation of the anchor chain is driven by a speed-regulating motor. Both the inlet and outlet active guide wheels of the anchor chain are equipped with speed regulation devices to ensure the synchronous operation of the anchor chain entering the disk, and the running speed is adjustable within the range of 200 to 1500mm/min. There is a driven wheel on the outside of the anchor chain inlet to guide the anchor chain to be cleaned. The centers of each guide wheel are all in a straight line to avoid misalignment during the operation of the anchor chain. ,
5. Electrical System The electrical and pneumatic system of this shot blasting adopts plc centralized control, which can not only achieve automatic control but also manual individual control. ,
The working process of the 3 QM anchor chain shot blasting cleaning machine. The anchor chain to be cleaned is hoisted and placed at the inlet. Then, the inlet wheel set is sent to the cleaning chamber through the upper sealed chamber. The high-efficiency cantilever centrifugal shot blasting machine throws the shot at high speed onto the surface of the workpiece to be cleaned, impacting and scraping the workpiece to remove the oxides and other attachments on the surface of the workpiece. After shot blasting cleaning, the anchor chain is continuously sent out by the guide wheels inside the chamber. After passing through the lower sealing chamber, the outlet guide wheel is sent out for unloading by the outlet driving wheel.
6. The process flow is as follows: crane hoisting - inlet wheel set - upper sealing chamber - shot blasting cleaning - inner guide wheel of the chamber - lower sealing chamber - outlet guide wheel - outlet driving wheel.
