General

The machine consists of several components.

• Blast Cabin
• Automatic Blast Guns & Up & Down Moving System
• Manual Controlled Blast Gun
• Abrasives Blasting System
• Abrasives Bags Filter Separating System
• Motorized Driven Conveying System
• Control System

Blast Cabin

It is a well closed chamber where sand blasting is taken place. Abrasive proof materials and surface treatments enables cabin durable and resistant to abrasives. There are gloves attached to holes on cabinet front where there are observation windows. Virgin or recycle abrasives are filled inside the cabin manually.

Automatic Blast Guns Up & Down Moving System

Inside blast cabin, there are several blast guns or, sometimes known as spray guns, traveling up and down automatically while glass is moving from inlet conveyor into the cabinet automatically. Steady movement of blast guns ensures consistent glass surface blasting finish. Up and down moving speed could be regulated. Position of each blast gun and angle of each blast nozzle are adjustable to obtain optimal glass surface finishes.

Manual Control Blast Gun

An extra manual spray gun is equipped for images carving on glass manually. Operator blasts the parts from the outside of the cabinet by placing his arms in gloves attached to glove holes on the cabinet, viewing the part through view windows and, manipulate blast gun manually.

Abrasive Blasting System

It is a siphon blast system, or sometimes known as suction blast system, using compressed air to create vacuum inside blast guns barrels. The negative pressure pulls abrasive into the blast gun via abrasive proof pipes. Compressed air directs the abrasives through blast nozzles impacting on glass. Abrasives are mixing with compress air during ejection, which fully utilizes compress air. Compress air quantity and abrasive amount are adjustable. Adequate mixing ratio minimizes abrasives and air consumptions.

Abrasive Bags Filter Separating System

It is a standalone structure. Dust separation is achieved by means of bags filtering. This process is a very high efficient way to capture reusable abrasive for recycling from disposal dust. During sand blasting, two types of contaminants are generated.

• a)　Glass powder physically eroded from glass surface.
• b)　Abrasives which become smaller in size or losing sharp edges after impacting on glass. These shattered abrasives are no more helpful for blasting.

Remaining abrasives are still large in sizes with sharp edges. They are reusable and are separated from dust by bags filtering system. Dusts are smaller and they pass through bags' tiny holes. Reusable abrasives are relatively larger in size and they are too large to pass through bags' tiny holes and finally they are collected in a box at the bottom of the separating system. There is a cylinder which is used to provide rhythmic vibration to shake the bags to make sure bags' tiny holes are not blocked. When abrasive collecting box is full, recycle abrasives are brought to blast cabin manually. Non-usable abrasive and dust are exhausted. They could be disposed in water drainage or water precipitation or any other ways fulfilling local laws and regulations with plumbing and facilities provided by buyer.

Motorized Driven Conveying System

It consists of inlet, main and exit conveyors with motorized rollers support. Main conveyor is inside blast cabinet. Glass is loaded on inlet conveyor. Motorized driven roller conveyors bring glass into blast cabinet automatically. Glass eventually comes out from exit conveyor. Speed is adjustable.

Control System

Operations are access from this control panel. All electrical and electronics parts and components are carefully selected.
