  木屑顆粒機生產中呈現顆粒有裂紋是什么狀況呢?今天我們就簡單引見,剖析下:
  What is the particle crack in the sawdust machine? Today we will briefly introduce and analyze:
  1,木屑顆粒產生垂直裂紋
  1. Vertical cracking of sawdust particles有些客戶在生產過程中,由于烘干機的選擇類型,不可以將木屑平均的烘干,形成原料木屑含水分不平均,在經過環模緊縮制粒后,會因水份的作用及原料自身所具有的彈性而彈開,產生了垂直裂紋。
  Some customers in the production process, because of the choice of dryer type, can not average drying sawdust, forming raw wood sawdust moisture content is not equal, after compacting granulation ring model, will be due to the role of moisture and the elasticity of raw material itself and springing, resulting in vertical cracks.
  2,木屑顆粒料彎曲且一面呈現許多裂紋
  2. Wood chips are bent and have many cracks on one side.

  這種現象通常是在木屑顆粒分開環模時產生的。在生產中,當切刀位置調得離環模外表較遠并且刀口較鈍時,顆粒從模孔擠出時容易被切刀碰斷或撕裂而非被切斷,此時有局部木屑顆粒彎向一面并且另一面呈現許多裂紋。這種木屑顆粒在進入冷卻器冷卻或運輸過程中,常常會從這些裂紋處斷裂,形成生產出的木屑顆粒粉料過多或者顆粒太短。木屑顆粒機3,木屑顆粒由一源點產生輻射式裂紋這種狀況的呈現主要緣由是木屑中含有比擬大的木屑形成的。纖維水平差不多的原料在制粒時才會使他們互相擠壓互相交融,如存在較大纖維,影響了纖維之間的互相作用。他不像其它較細的原料那么容易軟化,而在冷卻時,由于軟化水平不同,招致收縮量的差別,致使產生輻射式裂紋。
  This phenomenon usually occurs when the sawdust particles are separated from the ring mould. In production, when the cutter position is set far away from the appearance of the ring die and the cutter edge is blunt, the particles are easily broken or torn by the cutter when extruded from the die hole, instead of being cut off. At this time, there are local wood chips particles bending to one side and many cracks on the other side. In the process of cooling or transporting into the cooler, this kind of sawdust particles often break from these cracks, resulting in too much or too short sawdust particles produced. Sawdust granulator 3, sawdust particles from a source point to produce radiation cracks, the main reason for this situation is that sawdust contains comparatively large sawdust formation. Material with similar fiber level will extrude and blend with each other during granulation, such as the presence of larger fibers, which affects the interaction between fibers. He is not as easy to soften as other finer raw materials, but in cooling, due to different softening levels, resulting in different shrinkage, resulting in radiation cracks.
  4,程度裂紋橫過整個木屑顆粒
  4. Degree cracks cross the whole sawdust grain裂紋發作于木屑顆粒的橫切面,只是顆粒沒有彎曲。當將含有較多纖維的疏松的木屑制粒時,有可能發作此種狀況。這種木屑顆粒常常是在將木屑擠入環模的造粒孔時,由于其中含有比孔徑長的纖維,當顆粒被擠出后,因纖維的收縮作用使顆粒料在橫截面上產生橫貫裂紋,產生樅樹皮狀的木屑顆粒外觀。
  Cracks occur on the cross section of sawdust particles, but the particles are not bent. This condition may occur when loose sawdust containing more fibers is granulated. When the sawdust particles are squeezed into the pelletizing holes of the annular die, they contain fibers with a longer diameter than the holes. When the particles are extruded, the shrinkage of the fibers causes the transverse cracks in the cross section of the particle materials, resulting in the appearance of fir bark-like sawdust particles.
