Faster sandblasting process and minimum consumption with the BR-SM18

Go back to Blog



Balaguer Rolls R&D Department has recently introduced a new advanced sandblasting machine which gets a greater sandblasting capacity by obtaining a better sandblasting quality, while the energy use is reduced at the minimum. The machine presents significant advances in sandblasting technology, as the double sandblasting nozzle or the cyclone filter for separating fines.




Double sandblasting nozzle

The BR-SM18 Sandblasting machine includes two vertical nozzles for alumina and corundum gunning, getting a much faster and cleaner sandblasting process, since the double vertical nozzle obtains a more equalized sandblasting, avoids the table exit and reduces the shafts sandblasting at the minimum, by allowing to increase the advance speed.

Reduced air consumption

Air consumption is reduced at the minimum thanks to the venturi system of the double sandblasting nozzle and the suction system with hopper and filter, by reaching consumptions between 1050 NI/min at 4 bar and 1500 NI/min at 5.5 bar. Moreover, a constant clean and dry air supply is obtained in order to get optimal conditions in the rolls sandblasting.


Cyclone filter for fine separation

In order to obtain a more homogenous (Ra±0.25µ) roughness and sandblasting, BR-SM18 machine has a bag filter and cyclone suction system. Thus, the mix is recycled while the finer grains are separated in order to be finally suctioned and filtered. Therefore a constant uniformity regarding the grain size is guaranteed during the sandblasting process, apart from a clean and polluted air-free environment.


PLC automatic control

Parameters for all the sandblasting process are completely adjustable through the PLC interface. The integrated touch screen on the machine allows modifying parameters such as shaft and advance speed in an easy and intuitive way. Thus the sand gunning and translation movement are controlled throughout all the required area of the chosen roll.

In conclusion, the company introduces a revolutionary sandblasting machine which offers a faster and higher quality sandblasting process at the same time that the energy use for the client is reduced at the minimum.

Sandblasted rolls obtained ensure an optimal flour extraction, since, due to the achieved sandblasting uniformity, the flour extraction is made in optimal conditions without needing to put more pressure than needed on the rolls, by avoiding the flour overheating and the consequent damage to the raw material gluten.

The BR-SM18 machine is manufactured tailor-made according to the client needs, in ranges from Ø200 to Ø400mm and variable lengths between 100 and 3000mm, with a maximum weight per roll of 2.000 kg.
