Steel-Belt Tumble type shot blasting machine
Steel-belt Tumble shot blasting machine, equipped with rotating conveyor belts made of steel, ensure high production levels while prioritizing cost-effectiveness. Tumblast type shot blasting machine is designed for tumbling medium and large-sized items intermittently, allowing for manual or automatic loading using skip loaders.
Steel-belt tumble shot blasting machine, specifically designed with special abrasion-resistant casting #14 manganese reinforced steel belts, are primarily used for tumbling ferrous and non-ferrous castings, forgings, welding, and heat-treated parts. The skip loading capacity is 50 kgs per single piece, with a maximum total of 1000 kgs (volume 25L) per cycle.
The tumbler shot blasting machine with a skip loader can be seamlessly integrated into a fully automatic process by incorporating loading and unloading equipment, such as electricity or hydraulic tipping buckets. Skip loaders are typically employed for heavier workpieces and discharge into a vibratory conveyor.
The shot blasting machine’s housing is shielded by wear-resistant manganese-steel protective liners.
Features of Shot Blasting Machine:
- Batch cleaning capability reduces labor costs.
- Compact and foundation-free design with minimal noise.
- Consistently achieves a perfect surface cleaning finish.
- Ideal for solid parts resistant to collision during blasting.
- Environmentally friendly with no pollution.
Applications of Shot Blasting Machine:
- Foundry: Prepares for cutting, welding, painting, metallization, or surface finishing by desanding, stripping, and surface preparation.
- Custom-made: Tailored for surfacing, desanding, stripping, cutting, welding, drilling, or pre-painting preparation.
- Shot-Peening: Enhances the stressed and anti-fatigue strength.
- Aluminum die-casting: Provides uniform surface finishing.
- Forge: Achieves a homogeneous surface finish by deburring, removing laminate and coatings.

Characteristics of Crawler Shot Blasting Machine:
Airless Shot Wheel Turbines:
Shot turbines: Variable from 2200 to 3800 RPM for maximum abrasive velocity fitted with optional electronic inverter control; Upgraded wearing-resistance protective liners with low working noise & vibration;
Blade: Cast from unique wearing resistant alloy for extensive life with access design for easy change;
Durable Shot Blasting Chamber:
Shot blasting room: The shot blasting room is designed using CAD to achieve optimal blasting angles and distances.
It is constructed with durable profiles and 10mm plates, while the direct-blasting hot area utilizes upgraded manganese casting steel with 35-45 HRC for enhanced wearing resistance.
Rotary tumblast system:
Tumble belt: The continuous rubber belt or steel apron ensures easy loading and operation. The shot blasting equipment accommodates workpieces of various sizes, ranging from small to medium-large. The tumble motor is equipped with a Variable Frequency Drive (VFD) to adjust the rotary speed, enabling optimal blasting results:
- Steel apron belt is made of ZGMn13 long lifespan, design for the heavy-duty;
Loading system:
Skip loader: Automatic interlock PLC control facilitates the shot blasting process.
The loading bucket is electrically or hydraulically lifted, depending on the duty.
A vibrating conveyor transports blasted parts for unloading and collection.
For batch cleaning, a manual, mechanical, or automatic loading integration continuous belt conveyor aligns with production to load the chamber.
Recycle of abrasive material:
Elevator: The elevator raises the abrasive to the separator, utilizing a bucket made of foundry casting, while a tension device prevents belt slippage.;
Separator: The separator incorporates DISA & Pangborn technology, enabling the separation of abrasive into three classes with an impressive efficiency rate of 99.5%;
Dust collect system:
Cartridge filter: The dust collector filters utilize a cartridge-type system, boasting an exceptional efficiency rate of 99.9% and offering hassle-free replacement of cartridge filters;
Noise: Silencer to minimize of noise reach of 90dB;
Electrical Control system:
Electrical elements: All voltage adopts, overload protection on all motors, HMI (Human Machiner Interface) to monitor all elements;
Safety: The operation features a safety interlock system, while the control cabinet is protected with IP65 rating;
