  生物質顆粒機生產廠家選取原料多大粒度好?
  What size of raw materials does the biomass granulator manufacturer choose?
  木屑顆粒機在生產加工木屑顆粒時,到底木屑原料的尺寸好不好,成型無裂紋?龍騰新能源在木屑顆粒機的制造、安裝、調試等方面有十多年的經驗,發現木屑原料的粒度對成型有重要影響。
  Longteng New Energy has more than ten years'experience in manufacturing, installing and debugging of sawdust granulator. It is found that the size of sawdust raw material has an important influence on shaping.
  生物質顆粒燃料的主要材料形式是不同粒徑的顆粒。顆粒在壓縮過程中的填充特性、流動特性和壓縮特性對生物質的壓縮成型有很大的影響。生物質壓縮成型一般分為兩個階段。
  The main material form of biomass pellet fuel is particles with different particle sizes. The filling characteristics, flow characteristics and compression characteristics of particles in the compression process have great influence on the compression molding of biomass. Compression moulding of biomass is generally divided into two stages.
  在個階段,在壓縮初期,較低的壓力轉移到生物質顆粒上,改變了之前松散堆積的固體顆粒的排列結構,降低了生物質的內部空隙。
  In the first stage, in the initial stage of compression, the lower pressure is transferred to biomass particles, which changes the arrangement structure of the previously loose accumulation of solid particles and reduces the internal voids of biomass.
  在第二階段,當壓力逐漸增大時,較大的生物質顆粒在壓力作用下破碎,變成較細的顆粒,發生變形或塑性流動。此時,粒子開始填充空間,粒子之間的接觸更加緊密,相互嚙合。部分殘余應力儲存在成型顆粒中,使得顆粒間的粘結更加牢固。
  In the second stage, when the pressure increases gradually, the larger biomass particles break up under pressure and become finer particles, resulting in deformation or plastic flow. At this time, the particles begin to fill the space, and the contact between the particles is closer and mesh with each other. Some residual stresses are stored in the formed particles, which makes the bond between the particles more firm.
  顆粒越小,充填程度越高,接觸越緊密。當粒子尺寸足夠小(幾百幾微米)后,形成粒子內部約束力方法和主要和次要的變化,甚至粒子之間的分子引力和靜電吸引和液體附著力,毛細力)領先地位開始上升,將導致成型木屑顆粒,或形成一個不好的現象。

  The smaller the particle size, the higher the filling degree and the closer the contact. When the particle size is small enough (hundreds of microns), the method of forming internal binding force and the main and minor changes, even the molecular gravity and electrostatic attraction between particles and the liquid adhesion, capillary force) begin to rise, which will lead to the formation of wood chips particles, or form a bad phenomenon.

  木屑顆粒的不透水性和吸濕性與顆粒大小密切相關。然而,相反,由于顆粒尺寸越小,顆粒之間的間隙越容易填充,可壓縮性越大,成型顆粒內部的殘余內應力就越小,這就削弱了成型顆粒的親水性,提高了不透水性。那么什么是合適的芯片尺寸呢?關北機械工程師的經驗表明,1 ~ 5mm的鋸末容易形成,產生的鋸末顆粒外觀光滑,裂紋較低。當壓輥大于5mm時,壓輥與磨具之間的摩擦力增大,磨具的損耗增大。由于原料顆粒過大,產生的顆粒會從較大的顆粒原料中斷裂,而由于缺少與其他顆粒的咬合,幾乎沒有破碎的部分會出現裂紋。對小于1mm的原材料顆粒尺寸過大,會導致原材料顆粒之間的咬合不牢固,導致顆粒抗落,甚至不成形,木屑顆粒短等。
  The impermeability and hygroscopicity of sawdust particles are closely related to their size. However, on the contrary, the smaller the particle size, the easier the gap between the particles is filled, the greater the compressibility, the smaller the residual internal stress inside the formed particles, which weakens the hydrophilicity of the formed particles and improves the impermeability. So what is the appropriate chip size? The experience of Guanbei Mechanical Engineer shows that sawdust of 1-5mm is easy to form, resulting in smooth appearance of sawdust particles and low cracks. When the roller is more than 5 mm, the friction between the roller and the abrasive tool increases, and the wear of the abrasive tool increases. Because the raw material particles are too large, the generated particles will break from the larger granular materials, and because of the lack of occlusion with other particles, almost no broken parts will crack. For raw materials less than 1 mm, too large particle size will lead to weak occlusion between raw materials particles, resulting in particle resistance, even shaping, short wood chips particles, etc.
