Drum Blast Machines:

CNDR Drum Blast MachineCNDR Drum Blast 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.

CNDX Drum Blast – Sinto Surface Treatment’s CNDX is a small drum blast machine  capable of batch processing without mill jamming.  The CNDX Drum Blast Machine features 100% load/unload capabilities, highly efficient finishing due to oscillation during the blast cycle and a small machine footprint. The CNDX model is ideal for small to medium parts.

DB-3 Drum Blast– The DB-3 is a 3 cu. ft. drum blast machine specifically designed to process small parts found in multiple industries. An unique design eliminates part jamming and part loss as all parts are contained in the drum during the blasting process and carefully dumped after the process to ensure no part loss
