estructurasGRANALLADORAS ROCA designs and manufactures tailor­made shot blasting machines of continuous course for structures, profiles, bars, tubes and any other piece that fits in the entrance way the machine.

There are two big families of this type of machines:

­with turbines set at 90o from the pieces course.

­with turbines placed in a way that the abrasive blasting shoots from different angles onto the pieces.

The number and the power of the turbines are determined by the production required by the customer, resulting in different speeds in the pieces course.

The conveyor of the pieces can be a bed of parallel roller cylinders, over which the pieces roll; or an aerial conveyor that carries the pieces into the machine, allowing the possibility to connect it to a painting cabinet without innecesay waste of time.
