Rossini Ocrim S.p.A, Italy
The correct operation of an entire milling plant is determined by many factors, including some related to the design, the performance of all the machines, as well as correct and timely maintenance.
Ocrim has studied and designed the best way to optimise and enhance the mill's operation, linked to the performance of the rolling mills, in order to optimise both time and maintenance costs. This led Ocrim to focus on the grinding rollers, designing a solution that would incorporate as many benefits as possible for the end user.
For this market request, the solution presented by Ocrim involved including titanium coated rollers for the fluted passages in the grinding process, ensuring a much longer life of the rollers currently used by the entire milling industry. The Ocrim Research & Development Department, following this new engineering strategy, carefully studied the results related to the titanium coating of the rollers, in order to be able to share with its customers the important opportunities that this innovative product can offer.
The wheat grains are crushed to obtain flour and semolina, thanks to a combined action, involving grain cutting and its compression. The diagrammatic study to obtain the best possible yield from the plant is strongly affected by the state of the fluting of the rolling mill rollers. With new fluting it is possible to obtain the nominal yield of the plant because it is in the best conditions to achieve what is envisaged by the diagram, therefore it is crucial that the profile of the roller fluting is maintained for as long as possible.
The grinding rollers are all made of chilled-iron cast alloy with different hardness, according to the requirements or the technological diagram. The duration of the roller is thus directly dependent on its hardness. The fluting of a cast iron roller is preserved and, therefore, maintains its characteristics for longer when the roller has high hardness values (e.g. 530 HB).
In this regard, the Ocrim Research & Development Department has conducted several research studies and trials, achieving tangible results through the application of a special titanium coating for the corrugated rollers. This coating causes a considerable increase in the surface hardness values and consequently increases the duration of the fluting over time, to keep the ideal configuration of the plant as unaltered as possible.
