Definitions

  • the invention relates in particular to a method for impact milling of granular regrind such as grain or cubes the preamble of claim 1 and an impact mill with coaxial rotating rotors driven in opposite directions after the Preamble of claim 2.
  • It is particularly used for grinding regrind for animal feed.
  • impact mills have a fixed housing a rotor arranged and driven therein. It is also known disintegrators for very fine comminution with two coaxial, counter-rotating drives Form rotors (DE-A-3417556).
  • the rotors each carry at least two concentric blade rings, the Interchangeably intermesh blade rings of both rotors. Both rotors are driven by a common one Drive.
  • the one rotor is on a hollow shaft attached and the other rotor via a socket on one that Hollow shaft penetrating shaft arranged. Both waves are stored in an outdoor storage.
  • the high design effort is required to create a turbo effect according to EP-A-48012 to achieve with safe storage function.
  • the invention has for its object a method for Impact grinding of granular regrind and an impact mill for Implementation of the procedure to create the low technical and economic effort a high degree of uniformity the grinding of the ground material (low scatter of the Particle size) with a minimal content of dust fractions. This is done in a surprisingly simple way by the features of the characterizing part of the independent claims.
  • the regrind is first in a rotating movement accelerated and subsequently bounced by converting the speed vector into one of the acceleration opposite vector. Acceleration and Impact alternate cyclically in two intermediate zones, which are not yet comminuted enough by currents Particles are associated with excretion of particles desired size between cycles.
  • the regrind is passed to a first grinding stage, where it is accelerated in a defined direction and against one Surface of working organs bounces. Under the impact the regrind grains are in particles of different sizes communicating the opposite of the acceleration Shredded speed vector. Then the shredded Particles on a separator, where appropriate be separated. The separator is outside the shredding zone arranged and the particles approach tangentially on. The particles of the desired size are used as a finished product dissipated, coarse particles get into the Shredding zone to a second shredding stage and are subjected to acceleration and impact again however, unlike the first stage, finer Particles are created. A separation follows again in coarse and finished product outside the shredding zone, the coarse product again the first size reduction is fed.
  • a centrifugal channel according to DE-A-37 08 914 without a sieve in the channel cannot give a reasoned suggestion.
  • Required is a shift of the additional screen area mentioned in the arch area of the canal. This enables that Fine product almost completely when the required Granulation is sieved, which is compared to comparative solutions also significantly reduces the power requirement.
  • the channels are at the exit the cylindrical chamber to each other and form the common channel, which in the product direction in two separate crossed channels connected to the work areas are passes.
  • the strainer is placed in the curved part of the channel that a space is formed behind the sieve, which with the cylindrical space behind the sieve Chamber is connected by a pipe.
  • the shredding cycle is closed and the separation the particle occurs outside of what is both a subsidence of energy consumption and wear and tear Separation device allowed. At the same time it becomes a differentiated Treatment of different sized particles achieved.
  • the use of two shredding levels allowed an influence on particles with different processing intensity at every stage.
  • the process can be carried out in an impact or impact mill with a cylindrical Chamber with inlet and outlet nozzle for the Regrind as well as coaxially installed rotors in it attached work organs in the opposite direction rotate, run.
  • the chamber is perforated executed and divided into two chamber areas by means of the rotors, with the areas crossing each other Channels are connected that are outside their limits are arranged and the a closed flow of the Result in ground material.
  • the result is a closed grinding process with a predefinable one Particle size and the possibility of automatic Control the process.
  • FIGS 1 to 3 do not represent an embodiment of the invention.
  • An impact mill is fed with the material to be ground. This enters an in free fall via an inlet 2 first working area 12 of a chamber 4.
  • This is the regrind under the influence of a, by a rotary movement of a Rotor 6 generated airflow on a first row of blades 7 of the rotor 6 passed.
  • the individual grains of the ground material are captured by these blades 7, accelerated and against blades 9 of a rotor 8 at high speed thrown.
  • the blades 9 are located between the first and a second row of blades 7 of the rotor 6.
  • the number of transfer stages of the coarse fractions from the work area 12 in the work area 13 depends on the art of the ground material, its moisture and the intensity of the Impact.
  • a housing 1 of the impact mill In a housing 1 of the impact mill are horizontal and coaxial Rotors 6 and 8 with blades 7 and 9 attached thereto.
  • the rotors 6, 8 of surround a sieve 5, whereby a cylindrical chamber 4, the divided into two working areas 12 and 13 by the rotors 6, 8 is, is formed.
  • the rotors 6, 8 are driven by electric motors 10 and 11.
  • the rotor 6 has two rows and the rotor 8 has a row of blades 7, 9 divided with the rotor disk in half is. One half of the blades 9 of the rotor 8 is between arranged the rows of blades of the rotor 6.
  • An inlet 2 which is located on the side of the working area 12 on the housing 1 is arranged, is used to feed the impact mill with regrind.
  • channels 14 and 15 are on the housing 1 arranged to return the insufficiently shredded (coarse) particle fractions.
  • the channels 14, 15 are outside the chamber 4 arranged.
  • the width corresponds to that Channel 14 of the width of the row of blades 7 of the rotor 6, which is arranged closer to axis 16.
  • Channel 14 has one curved, curvilinear shape, starting from chamber 4 and laterally and centrally opening into work area 13.
  • Analogous Channel 15 is designed. He also leaves the chamber 4 and flows out laterally and centrally into the work area 12th
  • the size of the gap between the ends of the blades 7 and the sieve 5 is dimensioned so that the movement of the shredded Product on the screen 5 under the action of centrifugal force without direct influence from the outside Buckets 7 takes place.
  • the angle of attack of the blades 7, 9 is correspondingly small to choose the described, wear-reducing movement path of the particles.

  • the grain passes through the pipe 2 into the chamber 12, is with the blades 7 and 9, which on the corresponding rotors 6 and 8 are attached, crushed and comes on Sieve 5, where the ground product is separated into two fractions becomes.
  • the fraction of desired fineness is through the outlet 3 withdrawn from the device as a finished product, the Coarse fraction that does not pass through the opening of the sieve 5 has, is passed through the channel 23 to the sieve 17.
  • the shredded material is repeated Fractional separation.
  • the passage through the Sieve 17 enters the space located behind the sieve 18, from where it enters the space 19 behind the sieve the cylindrical 4 is steered.
