FP SPOMAX S.A. is one of the biggest European manufacturers and suppliers of cast iron rolls for the food processing industry. Rolls manufactured by SPOMAX are used for grinding, flaking and cracking products of vegetable and mineral origin.

The self-matting rolls The self-matting rolls are used primarily as milling rolls in the process of grinding wheat and rye. They replace the so-far used smooth rolls. The self-matting rolls can also substitute fine-corrugated rolls on final passages of flour mills. Moreover, they find application in the food industry (manufacturing of spices, condiments, etc.) and feed industry (manufacturing of fodder additives) as well as in chemical and pharmaceutical industry. The working part of self-matting rolls is a centrifugally cast iron sleeve with a special chemical composition and a special microstructure and lowered hardness down to ca. 400 HB. Selfmatting rolls developed by SPOMAX are manufactured from a special alloy and have a surface which stays rough during the lifetime of the roll. Special features of the working layer allow it to keep the required roughness for a long time. The application of self-matting rolls leads to an increase of flour extraction and to improvement of mill profitability. In case of 10 to 12 milling passages, replacing standard rolls with the selfmatting rolls an increase of passage flour extraction up to 2 to 3 percent and about 3 percent increase of total mill capacity has been recorded. Alternatively, by using self-matting rolls it is possible to achieve an increase of milling capacity of up to 5 to 10 percent while retaining the same extraction (higher load of the milling slot) or reduction of the number of milling passages by one or even two passages. Other advantages of the self matting rolls are: they do not get as hot as standard rolls, they ensure much better thermal conductivity as compared with standard rolls, they do not cause the product sticking, their lifetime is longer. Thanks to the application of the self-matting rolls it is possible to obtain a better flour quality as compared with flour production on standard rolls (an increase of bright flour extraction).
