Shot Blast Hoppers
GRANALLADORAS ROCA manufactures Shot Blast (and sand blast) movile Hoppers with single or double chamber of different capacities, designed to obtain the highest performance and the best safety conditions for workers.
Sand Blasting and Shot Blasting Hoppers are adapted for the use of any kind of abrasives either mineral, vegetal or metallic, offering a wide versatility.
The smaller models, as they can be easily transported, are ideal for construction work and small places or with difficult access.
Since the abrasive can be conveyed to every direction through rubber tubes, these hoppers are appropiate for open air jobs (where the recovery of the abrasive is difficult) such as sand blasting of big structures, ships, bridges, etc.
