Claims (14)

1. Способ измельчения сухих частиц и отделения частиц продукта от отсеянных частиц, включающий: а) подачу сухих частиц в устройство, содержащее: 1) удлиненное полое цилиндрическое сито (1) с множеством радиальных отверстий (4), диаметры которых меньше диаметра частиц продукта; 2) проходящий аксиально внутренний канал (3), выполненный внутри цилиндрического сита (1), в котором радиальные отверстия (4) проходят из внутреннего канала (3) сквозь сито (1), внутренний канал (3) имеет вход (2) на одном аксиальном конце для приема частиц продукта вместе с некондиционными частицами, а также выход (10) на другом аксиальном конце для удаления частиц продукта; 3) втулку (7), расположенную во внутреннем канале (3), в котором при вращении сита (1) относительно втулки (7) некондиционные частицы, находящиеся внутри канала (3), отбрасываются радиально наружу и удаляются через радиальные отверстия (4) на сито (1), при этом частицы продукта перемещаются в выход (10), предназначенный для этих частиц; и выход (14) для некондиционных частиц, выходящих через радиальные отверстия; б) извлечение частиц продукта, в котором частицы имеют математически усредненное отношение длины к диаметру от 1,0 до 4,0.1. A method of grinding dry particles and separating product particles from screened particles, comprising: a) supplying dry particles to a device comprising: 1) an elongated hollow cylindrical sieve (1) with many radial holes (4), the diameters of which are smaller than the diameter of the product particles; 2) axially passing inner channel (3), made inside a cylindrical sieve (1), in which radial holes (4) pass from the inner channel (3) through the sieve (1), the inner channel (3) has an input (2) on one the axial end for receiving particles of the product along with substandard particles, as well as the outlet (10) at the other axial end for removing product particles; 3) a sleeve (7) located in the inner channel (3), in which, when the sieve (1) is rotated relative to the sleeve (7), substandard particles inside the channel (3) are thrown radially outward and removed through radial holes (4) on a sieve (1), while the particles of the product are transferred to the outlet (10) intended for these particles; and output (14) for substandard particles exiting through radial holes; b) the extraction of particles of a product in which the particles have a mathematically averaged ratio of length to diameter from 1.0 to 4.0. 2.

The particle composition obtained by using the method according to claim 1, containing essentially cylindrical particles extruded from a pasty material and having a mathematically averaged ratio of length to diameter from 1.0 to 4.0 with a standard deviation of less than 1.0. 9. Композиция по п.8, в которой отношение длины к диаметру составляет от 1,8 до 2,7 при среднеквадратичном отклонении меньше 0,9. 9. The composition of claim 8, in which the ratio of length to diameter is from 1.8 to 2.7 with a standard deviation of less than 0.9. 10. Композиция по п.8 или 9, содержащая используемые в сельском хозяйстве частицы, образующие по существу стабильную смесь. 10. The composition of claim 8 or 9, containing particles used in agriculture, forming a substantially stable mixture. 11. Способ по п. 1, в котором подаваемые частицы содержат частицы, экструдированные из пастообразного материала. 11. The method according to p. 1, in which the supplied particles contain particles extruded from a paste-like material. 12. Способ по п. 1, в котором подаваемые частицы содержат по существу цилиндрические экструдированные частицы. 12. The method of claim 1, wherein the feed particles comprise substantially cylindrical extruded particles. 13. Способ по п. 1, в котором усредненное отношение длины к диаметру составляет приблизительно от 1,0 до 4. 13. The method according to p. 1, in which the average ratio of length to diameter is from about 1.0 to 4. 14. Способ по п. 13, в котором усредненное отношение длины к диаметру составляет приблизительно от 1,5 до 2,8. 14. The method according to p. 13, in which the average ratio of length to diameter is from about 1.5 to 2.8.
