Rubber Belt Tumble Blaster

ISTblast Rubber Belt Tumble Blasters deliver efficient, affordable batch processing to automate the cleaning, peening, and finishing of workpieces varying in size.

The endless rubber belt keeps parts gently tumbling as they are exposed to blast streams on all surfaces. This system is ideal for batch processing a set of small pieces at once, as well as relatively heavy, complex-shaped parts that would be hard to handle in a traditional sandblast cabinet.


  • Equipment has a small footprint.
  • Processes several pieces at a time (batch cycle).
  • Simplifies the surface treatment of small, hard-to-hold pieces.
  • Rubber belt ensures a gentle tumbling motion on delicate parts.
  • Fully automated process controlled by PLC and interfaced with an intuitive HMI touch screen.
  • Low-maintenance.


Simply load parts on the rubber belt and set the timer, then return later to unload perfectly cleaned or finished parts.

As parts tumble, three or more nozzles uniformly blast all exposed surfaces to deliver a consistent finish automatically. Nozzles are mounted on an oscillating blast gun to ensure maximum coverage of all parts.

Parts tumble on a thick, perforated rubber belt which allows blast media to fall through. Blast media is continuously reused after being cleaned by a cyclonic separator to sort out dust and process contaminants, returning only blast media in good shape back to the blast nozzles for optimal results.

  • Endless Rubber Mill: Wear-resistant, 30”-wide rubber belt with a loading capacity of 200 lbs and a filling volume of 3 cu. ft.
  • Custom Design and Fabrication: Each system is tailored to the customer’s specifications to address all process constraints and for optimal results and productivity.
  • Personalized Process: Personalize your process by varying abrasive media, blast nozzle size, blasting pressure, table rotation speed, and blasting cycle time.
  • Fully Automated Cycle: Process sequences are controlled by PLC and interfaced with an intuitive HMI touch panel.
  • Baghouse Dust Collector: Choose from a range of high-efficiency baghouse dust collectors for both optimal blasting performance and minimizing wear and tear on critical components.
  • Media Reclaiming System: Cyclonic separation of contaminated abrasive media for optimal performance – dust and by-products are diverted to the dust collector.
  • Electricity: Available in all voltages and frequencies.
  • Compliance: Design and door switches comply with OSHA requirements and most local safety jurisdictions.
  • Parts Cleaning: Automatic blow-off cycle to remove all dust and contaminants from the freshly-blasted parts.
  • Liner Protection: Rubber lining protection on the inner wall, rotating table, and media reclaimer for extended service life (Linatech).


  • Tower Status Indicator Lights: Stack lights offer modular stackable components that provide illuminated and audible status indication for machines, systems and process.
  • Baghouse Dust Collector Optional Package: Improve your standard dust collector efficiency and performance with the addition of an automatic cleaning procedure on filter media, a vertical or horizontal muffler, and a sealed dust collection drum.
  • Cartridge-Type Dust Collector Upgrade: Increase your overall process quality and efficiency with a fully-equipped cartridge dust collector able to capture up to 99.9% of particles down to 5 µm.
  • HEPA Filters: Our dust collectors are designed to fit a HEPA filter when the process requires it, which can capture 99.98% of particles down to 0.3 µm.
  • Parts Handling Robots: Automate tedious and unsafe parts handling tasks with a dedicated robotic arm.
  • Loading/Unloading System: Facilitate the loading/unloading procedure for heavy parts while preventing injuries in the workspace.
  • Remote PLC I/O: Benefit from remote access assistance on the PLC, allowing for instant troubleshooting and easy software updates.
  • MagnaValve Abrasive Regulator: The MagnaValve and controller provide an accurate regulation of ferrous and non-ferrous media in shot peening and blast cleaning applications where accurate and repeatable flow rates are desired.
  • SWECO Vibratory Media Classification System: The SWECO particle separation and sifting system provides an accurate media classification and sizing for precise peening or blast cleaning applications.
