 Rolls for Flour Mills:

  Jai Bharat Castings are manufacture & exporter of chilled rolls for roller flour mills by centrifugal spin casting technique, using controlled rotational speed & precise double pouring to produce these rolls, this is the most contemporary and sophisticated method to produce high quality duplex rolls, the cementite & paralytic structure ensures that the rolls have consistent hardness over the entire surface (18-20 mm chilled depth) these rolls are available in sand blasted, smooth & fluted surface finish along with grinding and grooving, completed with shrunk fit forged en-8 & en-9 journals and bearing size operations according to milling bodies of overseas & Indian flour mill manufactures, however semi-finish rolls are also available for further harmonizing of journals  

Advantage:
JBC manufactured rolls are made for high peripheral speed roller flour mills therefore these chilled rolls manufactured dynamically balanced, due to our advance centrifugal casting technique, lighter impurities like oxides & gas float more quickly towards the center of rotation from molten metal, where they are easily machined, thus gives a clearer working outer surface, because of the much-reduced cross section of the shell material, a faster cooling rate is obtained harder chilled layer which ensure longer life of rolls
