Rotating blades are the core heart of SBM-H-C automatic sandblasting machine. This innovative process is completely free of compress air. Instead of vacuum in traditional air blasting process, abrasives are accelerated by rotating flat blades. When rotating blades get in touch with abrasive physically, the blades heavily hit abrasives which then gains enormous energy. This energy is transformed to momentum energy. Due to its light weight, abrasive travels at ultra high velocity downwards impacting on glass surface. Fine blasted surface is then obtained with this revolutionary airless blasting process.

Blast Cabin

It is a well sealed structure where sand blasting is taken place. Abrasive proof materials and surface treatments enables the cabin to be durable and resistant to abrasives. There are tiny 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.

Rotating Blades System

This rotating system is shielded inside the blast cabin. Several pieces of steel blades are well joint together to form a turbine like structure free of rotation. Driven by durable high speed motor, steel blades rotate freely at high RPM. When abrasives fall down and touch steel blades, rotating steel blades heavily hit abrasives which then travel in high velocity downwards. Abrasives eventually impact on glass traveling on flat belt conveyer underneath.

Abrasive Collecting Tank

The tank is situated beneath at exit of flat belt conveyer. It is used to collect excessive abrasive left on flat belt and glass surface after blasting. After glass is sandblasted and travels to exit of belt conveyor, remaining abrasives left on glass surface are removed onto flat belt. These abrasives, together with excessive abrasive left on flat belt, are then conveyed upside down backwards to entry section. There are traverse brushes beneath flat belt but right above abrasive collecting tank. Brushes remove abrasives from upside down belt onto the tank by means of gravity. Virgin abrasive is added in this tank when necessary.

Bucket Elevating & Recycling System

This elevator is well sealed in a standalone tower located next to blast cabin. Several buckets move up and down like a merry-go-round. Abrasives inside abrasive collecting tank are carried upwards by buckets to subsequent separating system.

Abrasives Bags Filter Separating System

It is a standalone structure. Dust separation is achieved by means of bags filtering. Bags filtering is a very high efficient way to capture reusable abrasives 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.

Abrasives Storage

This tank structure locates above blast cabin. All filtered usable abrasives arrive at this storage and are ready for homogenous process.

Twin Screws Homogenizer

This screws system lies inside the abrasive storage, above the rotating blades. Screws are driven by durable motor. Abrasives inside the abrasive storage are not homogenous enough for adequate blasting. When the twin screws are rotating, they transform and make abrasives uniform when abrasives accessing through the screws. Consistent abrasive density is then obtained. Abrasive falls down uniformly like a water fall but with well controlled layer and amount. This is very helpful for a fine exquisite glass surface.

Dust Collection

After separating, usable abrasives are recycled and are brought back for blasting again. Non-usable abrasive and dust are eventually collected in this dust collector.

Flat Belt Conveying System

It consists of inlet, main and exit conveyors. Main conveyor is inside 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 the exit conveyor. Belt is abrasive proof. Speed is adjustable. There are brushes beneath the belt at the exit end. The brushes remove all dust remaining on the flat belt thoroughly leaving a clean belt surface for the next glass loading.

Control System

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