Automatic Horizontal Glass

Sandblasting Machines

(Air blasting process with blast nozzles powered by compress air with bags filter separating system)

Series: SBM-H-B

Blast Cabin

It is a well sealed chamber where sand blasting is taken place. Abrasive proof materials and surface treatments enables the cabin to be durable and resistant to abrasives. There are narrow openings at both sides of the blast cabin. They allow glass to go in and out. These tiny inlet and outlet openings are specially sealed avoiding abrasives and dust from escaping. There are observation windows allowing real time monitoring.

Automatic Blast Guns & Traverse Moving System

Inside the blast cabin, there are several blast nozzles or, sometimes known as spray nozzles, traveling transversely to and fro automatically against the glass traveling direction. Steady oscillating movement of the blast guns ensures consistent glass surface blasting finish. Traverse moving speed could be regulated. Position of each blast gun and angle of each blast nozzle are adjustable to obtain optimal glass surface finishes.

Abrasive Blasting System

It is a siphon blast system, or sometimes known as suction blast system, using compressed air to create a vacuum inside the blast gun barrels. The negative pressure pulls abrasives 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 the compressed air. Compressed 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 with plumbing provided by buyer or any other ways fulfilling local laws and regulations.

Motorized Driven Conveying System

It consists of inlet, main and exit conveyors. Main conveyor is inside the blast cabinet. Glass is loaded on the inlet conveyor. Motorized driven conveyors bring the glass into the 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.
