Shot blasting of casts, welded constructions, forged and pressed parts, and various complicated parts (including cylinders, springs), etc. To clean surface, removing casting sand & filings, consolidating the surface (micro handling), roughing the surface before painting, etc.

Pretreat objects are individually or in a group hanged to the revolving hoist and transported to the machine via conveyor. Rotating of treated objects provides efficient treatment of less accessible parts of their surface. The machine’s housing is protected by wear-resistant rubber and ZGMn13.
Machines may be produced through order, with customized size, quantity and power of turbines, the hanging conveyor type, rotating hangers capacity. The hoist and trolley drive may be manufactured in accordance with the buyer’s requirement. 

Puhua overhead rail shot blast machines can be used for a wide spectrum of applications and workpiece shapes and sizes.
• Versatile transport technology
• Highly efficient blast wheels
• Multiple machine sizes and variations available
• Removal of mill and forge scale as well as rust
• Removal of burrs and scales
• Removal of moulding sand
• Increase of surface roughness
• Shot peening to increase fatigue strength
Applications include blast cleaning welded steel fabrications, deburring and homogenising diecast parts, and peening dynamically stressed components. Batches of small components or singular large, heavy workpieces can be treated.
This flexibility is achieved by several special features:
Blast wheels
Blast wheels provide a very efficient abrasive pre-acceleration, which allows for short treatment times, high performance and a superior blast process.
Rotation and oscillation
To achieve complete coverage, the workpiece carrying hooks rotate and stop automatically at three automatic workpiece feed different points in the blast cabinet. This rotation and oscillation process means that even highly complex workpieces, with hard to reach surfaces, can be safely and accurately treated.
Hook and hoist options
The transport system can be designed for different weights. As an option, carrying hooks are available with integrated chain hoists for operational ease and safety.
Special Features and Options
The Process
The workpieces are transported manually on rotating hooks or automatically on an overhead rail system into the blast cabinet. The blast cycle runs in accordance with the preset program and blast time.
Standard machine:
Used abrasive and fines fall through the abrasive collection hopper beneath the blast cabinet and are transported via a screw conveyor to a bucket elevator and to the abrasive reclamation unit. In the reclamation unit, the used abrasive is separated from fines and contaminants and returned to the abrasive silo.
Abrasive reclamation options:
For improving abrasive cleansing, e.g. separation of aluminium flashes, a vibro sieve can be installed between the reclamation unit and abrasive silo.
Option for foundry/heavy-duty applications:
A vibro conveyor can replace the screw conveyor to provide targeted cleansing/ separating of sand and heavy contaminants from the used abrasive. The conveyor should ideally be installed with a magnetic separator (also optional) to remove sand in order to prolong the service life of the machine. The abrasive then goes to the airwash separator as before.
Vibro Conveyor
In place of the standard screw conveyor, a vibro conveyor can be used to transport abrasive from the blast cabinet to the bucket elevator. The sieve installed in the vibro conveyor separates coarse fines from the abrasive. For dust removal, the conveyor is linked to the dust filter of the central machine.
Vibro Sieve
For a blast process without interruption, a vibro sieve is used to clean abrasive. The vibro sieve is used after the abrasive reclamation unit and sieves coarse particles, such as flashes from aluminium diecasting workpieces, from the abrasive so that they do not affect the blast process. The sieve is installed above the silo. It is driven by two vibro-motors and set in motion similar to a shaker sieve. A targeted sieving of unwanted fines is achieved with the mesh size adapted to the process. Fines are automatically fed into a bin. Lateral flaps allow easy access to the sieve for ease and maintenance.
Magnetic Separator
The magnetic separator increases your profitability by reducing machine wear and reducing abrasive consumption. Moulding and core sand on castings is removed during the blast process. As they cause high abrasion they must be separated from the ferro-magnetic abrasive quickly and efficiently. This is performed in the magnetic separator. Two rollers with adjustable magnetic fields and a sieving box separate the moulding and core sand and fines from the reusable abrasive, in this way only 0.2% of the weight remains. This reduces wear and abrasive consumption and leads to higher profitability for you.
