Shot Blasting Machines with Conveyor Belt made by Steel-Belt

Rubber-belt Tumblast shot blasting machine / Tumble belt shot blasting machine with rotate conveyor belts by rubber & steel are designed to allow high production levels, at priority is low costs, a tumbler of medium and large-sized items, in intermittent, loaded by manual or automatically by the skip loader.

Steel-belt tumble belt shot blasting machine type ST, comprising segments made from special abrasion-resistant casting #14 manganese reinforced steel belts are mostly tumbler to process ferrous and non-ferrous castings, forgings, welding, and heat-treated parts. The loading capacity is 50 kgs of single piece, maximum total 1000kgs (volume 25L) per time;

The tumbler shot blasting machine with skip loader, can be integrated to a fully automatic process with the addition of loading and unloading equipment via electricity or hydraulic tipping bucket. The use of skip loaders is normally applied for heavier work, discharging into a vibratory conveyor.

The shot blasting machine’s housing is protected by wear-resistant manganese-steel protective liners.

Features of Shot Blasting Machine:

Batch cleaning and save labor cost;
Compact design structure, no foundation required, low noise;
Perfect of finishing consistency of surface cleaning;
Specific suits for the solid parts which not afraid collision during blasting;
No pollution for the environmental protection;

Applications of Shot Blasting Machine:

Foundry: De-sanding, stripping and preparing for cutting, welding, painting, metallization or surface finishing of bronze and aluminum;
Forge: Deburring, removal of laminate and coating, homogeneous surface finish.
Aluminum die-casting: Surface blasting finishing uniform.
Shot-Peening: Increasing the stressed & fatigue strength of components;
Customized-made: Surfacing De-sanding, stripping and preparing for cutting, welding, drilling or pior preparing of painting etc.

2. Shot Blasting Chamber:

Shot blasting room design with CAD (Computer-Aided Design) reach of best blasting angle and distance;
Blasting room made of strong profiles and 10mm plates;
The direct-blasting disc use of upgraded wearing-resistance Chrome and Manganese casting steel with 35-45 HRC;
The double doors open and closes manually, pneumatic or electricity, with tight sealing;
Fully safety interlocks;
Labyrinth structure to stop the abrasive leak;

3. Rotary tumblast system:

The continuous rubber belt or steel apron, very easy of loading and operation;
- Steel apron belt is made of ZGMn13 long lifespan, design for the heavy-duty;
The workpieces range from smaller size to medium-large size;
VFD (Variable Frequent Drive) for the turntable motor to adjust the rotary speed to achieve of best cleaning;

4. Loading bucket & unloading conveyor:

The automatic interlock PLC control with shot blasting process;
The loading bucket is lifted by electricity (light duty) or hydraulic station (heavy duty);
The vibrating conveyor to carry the blasted parts for unloading collection;
Manual, mechanic or automatic loading integration continuous belt conveyor aligned with production for loading chamber of batching cleaning;
