Grinders

IN CONTRAST TO HIGH-SPEED SPLITTING OF GRAINS IN HAMMER MILLS, WITH ROLLER GRINDING USING LOW-SPEED DIMINUTION OF GRAINS BY SHEERING, LOWER ELECTRIC ENERGY CONSUMPTION IS ACHIEVED. EVEN THOUGH ENERGY SAVINGS ARE REDUCED WITH DECREASING GRAIN COARSENESS IN DIRECT PROPORTIONALITY, EFFECTIVENESS OF ROLLER GRINDERS IS REMARKABLE AND PURCHASE COSTS RETURN RELATIVELY RAPIDLY.
  • Compared to hammer mills, a roller machine saves more than 40 % of electric energy costs when processing wheat; moreover, energy savings exceed 70 % when processing barley.
  • Excellent energy balance can be achieved with two-stage assemblies. The roller machine either pre-processes the raw material for a remilling by a hammer mill or, even better, for another roller grinder.
  • Unlike hammer mills for which it is possible only by replacing sieves, the size of particles for specified feed mix granularity may be regulated promptly and precisely.
  • Grinds produced with roller grinders distinguish themselves by their homogenous structure; hammer mills: their production is characterized by fine to medium particles ratio of 2:3, while a typical ratio for roller machines is 1:9 and the specific gravity of a product is approximately by 10% lower.
  • Should farmers need fine grinds, their requirements may be fully satisfied by roller grinders equipped with finer-grooved rolls and narrow milling gap thus producing fine feed structure.

Nutritional Value

It has been proved that nutritional value of a feed mixture is affected not only by composition of nutrients, but also by their physical structure.
  • All kinds of feed mixtures, practically for all animal species and categories, including fine grinds for weaned piglets, may be produced with the ROmiLL grinders.
  • Bigger particles do not exercise negative influence on production efficiency as for pigs and do not leave any pathological changes on alimentary tract mucous membrane.
  • Fine grind slightly increases digestibility of some nutrients with pigs; however, this increase is not significant enough to be profitable taking increased grinding expenses into consideration – see table.
  • Negligible portion of floury fractions for instance reduces the occurrence of health and dietetic troubles with dairy cows.
  • As to nutrition, usage of fine grinds has proved to be well-founded only with market fish. Nevertheless, even in this case, it is regarded as a positive contribution that bigger feed particles float on the water surface and fish consume them while dust portions fall to the sediment.
