ROLLER GRINDERS, CRUSHERS AND CRIMPERS FOR LARGE-SCALE FEED MILLS PRINCIPLE The roller mills and crumblers diminute grain by shear when going through the milling gap between two corrugated rollers with edges, turning in different speed. The slower roller turns even faster than the rollers used in roller crimpers that process the feed by the influence of pressure, rising between two nearly smooth rollers, turning in the same circumferential speed. The ROmiLL S900 machine is used for grinding the grain to groats. Its modification SG900 is used as the pellet crumbler and SR900 is used as the rape seed crumbler. The crimper ROmiLL M900 processes the grain by application of pressure to the cohesive flake structure. SUMMARY OF ADVANTAGES: ❯ Against hammer mills, with fine milling for swines you can save about 30 %, and with coarse milling for poultry even up to 70 % of energy. ❯ The feed value of grind from roller mills enhances feed digestibility and production efficiency. ❯ The crimped grain in the milking cows feed ration improves efficiency by 0.5 litre per head and a day. OPERATION PARAMETERS electromotor (3x400V, 50 Hz) production fine product capacity coarse product weight DETERMINATION The machines are mainly used for processing of most feed mixtures. They are especially suitable not only for grain crops – wheat, barley, oats, maize – , but also for other feed crops, e.g. legume, oil-bearing crops, oil cakes etc. They are not suitable for processing of stalky crops with long fibres. The products processed are used for feeding of farm animals of all kinds and categories, mainly with addition of feed additives. ANOTHER USE The machines can also be used as mills, crushers, crimpers etc. for diminuting of other biological materials as well as inorganic raw materials in a wide variety of non-food applications. MAIN USERS The 900 Series products of ROmiLL model range are the most powerful from the point of view of processing capacity. They are mainly installed in the industrial feed mills, but also in larger primary agricultural production companies. They are used by the agriculture supply and purchase companies, large cooperatives or business companies or associations. They are determined for continuous and shift operation. Together with mixers, scales, conveyors, feeders they are installed in standardized or individually projected middle- or large-capacity feed mills.

It uses much lower power supply and allows processing by crimping as well. Another advantage of roller mills is that they produce groats with homogenous texture, which is optimal for animal feeding. Thanks to the possibility to adjust the particle size exactly, reaching the rated graininess of all types of feed mixtures is enabled.

is unable to keep up the permanent parallelity of both rollers and so the permanent size of the grinding gap along its whole length, the movable roller in ROmiLL machines makes a firm framework which protects the roller axis against displacement from the exactly determined position. Feeding hopper The feeding hopper capacity corresponds to that of the machine. The hopper is equipped with a mechanism that regulates the amount of the processed raw material. If the rollers separate, it works as a fast lock. The accessory hopper lid closes the accumulated amount of material inside the hopper. The...
