Fodder production line management system

     Combined feed (fodder) is a homogeneous mixture of forage resources (grain, bran, fodder of animal origin, mineral supplements) high in protein, vitamins and minerals for farm animals and poultry nutrition. Depending on fodder feeding value it is divided into: full fodder, mixed fodder concentrates, balancing fodder supplement (protein-vitamin, protein-vitamin-mineral) and premixes.

     Extrusion method is the most popular among all methods of animal feed production. It allows to improve the qualitative properties of the end product compared to traditional methods. During the production process the feed is effected by brief and very intense mechanical and barothermal impacts, which are followed by structural, mechanical and chemical feedstock changes. Due to the short duration of the process, vitamins and amino acids, which are contained in grains, are almost completely saved. And digestibility is increased to 90%. Extruded feedstock is practically not affected by bacteria when stored under normal warehouse conditions (for 3-4 months). This fact is of special value for the fattening of young animals (cattle, pigs, horses, rabbits, etc.). Feeding young animals with extruded feedstock 1,5-2 times reduces their gastrointestinal disease mortality. It should be noted that the quality of the finished product is not affected by humidity of the processed raw materials and possible small number of seeds of other crops.

     Flowsheet and equipment are selected depending on formulation and the manufactured feed, find out more:

System diagnostics of bell-type furnaces thermal separation

     Main indicator of metallurgical production is quality of the products. Thus one of the most important elements of the technological process is heat treatment. All kinds of hot-rolled and cold-rolled steel have to be heat-treated: sheets, pieces, wires, rails, pipes, tapes, etc.

     During cold rolling, stamping or drawing the grains of the metal deform and crush. This effect is called hardening. The hardening increases metal hardness and reduces its ductility, causes brittleness. Recrystallization annealing is used to eliminate hardening. In the shops of cold rolling, recrystallization annealing is used as:

  • procedure prior to the cold processing of metals by pressure - in this case, the material becomes more ductile, easier for its further processing;
  • output type of heat treatment - end product or semi-finished product get the required production specifications;
  • intermediate step in the metal cold deformation process: annealing makes possible to remove hardening effectively.
     To implement this type of heat treatment in cold-rolling shop of JSC "Zaporizhstal" bell-type furnaces are used,  more info
