Rubber and Steel Belt Tumblast shot blast machines used for the cleaning of work suitable for a tumbling process. Pieces with sizes and weights ranging from a few grams up to 10Kg for rubber belt machines and from a few hundred grams up to 250Kg for metal slat machines.
Typical work for rubber belt machines would be

• Screws, bolts in preparation for galvanizing
• Aluminum die-castings for Automotive and motor cycle industries, lighting, telecommunications, power tools etc.
• Brass and steel hot pressings
• Thermosetting

For Steel Belt machines castings from the ferrous and non ferrous industries

• Castings
• Pressings in steel and brass
• Forgings
• Springs
• Heat-treated parts

Loading and unloading of Tumblast machines may be either manual or automated. The use of skip loaders is normally applied for heavier work, discharging onto a vibratory conveyor for side discharge into bins.

Roller Conveyor type shot blast machine.
A complete range of work to be treated ( sheets, profiles, angles and channels as well as fabricated steel constructions, pipes, etc) pass through the blast chamber supported by rollers.

Descaling and removal of oxides occurs during the passing of work pieces through the blast chamber.

Positioning of the shot throwing wheels in the design of the blast chamber is possible to achieve single pass cleaning, according to ISO 8501-1 and SIS SS 055900.

Suitable brush & blower inclusions remove any residual abrasive.

The external loading and unloading roller conveyors are modular.

The LAMI machine may be inserted in automatic cleaning and painting situations ( LAMIVER).

The lay-out of these treatment lines would include

• Loading cross transfer
• Pre-heat oven
• Blast cleaning LAMIVER
• Auto paint booth
• Drying tunnel
• Unload cross transfer

Tunnel machine type carousel, to treat work pieces suspended on a rotating hook.
Hooks are distributed at a constant pitch on an overhead endless loop monorail system.
Loading and unloading of work pieces are carried out during the shot blast machine processing phase.
SCM shot blast machine is particularly suited for high capacity or in-line production and painting installations.
Typical work for SCM machine would be:

• Aluminium die-castings (automotive, lighting, motor cycle industries etc..)
• Structural steel works
• Gears (post heat treatment)

Heavy-duty version:

• Cast parts in iron, steel and aluminium
• In this case, the shot blast machine is fitted with special components such as magnetic separators, vibrating screens, etc..
