Drum blast machines by Sinto Surface Treatment allow for faster, safer and cleaner finishing.  The CNDR features smooth load/unload capabilities, highly efficient finishing due to drum oscillation during the blast cycle, and a zero pinch design, eliminating jams that occur in a conventional mill. The CNDR ranges from 14 ft3 to 35 ft3 with a load capacity range from 330 lb. to 7500 lb. The drum blast machines use Sinto’s Y-30 direct-drive wheel. In the foundry industry, the drum shot blasting machine has a 99.75% removal of contaminate on first pass and can remove 8% of sand contaminates by weight.

Sinto America’s Drum Blasting designs are engineered specifically for parts that have previously been hard to clean by blasting in the traditional style of tumble blast machine designs.The CNDR models are capable of cleaning a broader range of castings, and by virtue of their design, require significantly lower maintenance than conventional tumble-type blast machines that result in significant savings.


  • Consistent and highly efficient
  • Drum oscillates while processing, reducing cycle time over conventional drum styles
  • Zero pinch design eliminates part jams
  • No leak design improves safety environment
  • Smooth, reliable loading with the hydraulic loader
  • Reduced maintenance vs tumble blast
  • WE-3 Air-Wash Separator: High efficiency reverse flow technology
  • Reduced part damage vs tumble blast
  • 100% manganese process drum with an increased working life
  • 99.75% removal of contaminate on first pass
  • Removes 8% of sand contaminates by weight
  • Options include: Heavy Duty (HD) version, dust collector/ducting, conveyor, auto shot adder, maintenance platform/ladder, weight scale and more


  • Functions as a part counter or weight meter under the bucket loader
  • When the part count or weight reaches the desired capacity, the weight scale signals the bucket loader to discharge its content into the blast machine
  • After the bucket loader returns to the home position, the scale resets to zero
  • When used in combination with a continuous feed system such as a conveyor that is off loading into the bucket loader, it allows a batch style machine to function in a continuous mode of automatically loading multiple batches of parts, therefore eliminating the need for an operator to start the machine for each batch
