  木屑颗粒机生产中呈现颗粒有裂纹是什么状况呢?今天我们就简单引见,剖析下:
  What is the particle crack in the sawdust machine? Today we will briefly introduce and analyze:
  1,木屑颗粒产生垂直裂纹
  1. Vertical cracking of sawdust particles有些客户在生产过程中,由于烘干机的选择类型,不可以将木屑平均的烘干,形成原料木屑含水分不平均,在经过环模紧缩制粒后,会因水份的作用及原料自身所具有的弹性而弹开,产生了垂直裂纹。
  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,木屑颗粒料弯曲且一面呈现许多裂纹
  2. Wood chips are bent and have many cracks on one side.

  这种现象通常是在木屑颗粒分开环模时产生的。在生产中,当切刀位置调得离环模外表较远并且刀口较钝时,颗粒从模孔挤出时容易被切刀碰断或撕裂而非被切断,此时有局部木屑颗粒弯向一面并且另一面呈现许多裂纹。这种木屑颗粒在进入冷却器冷却或运输过程中,常常会从这些裂纹处断裂,形成生产出的木屑颗粒粉料过多或者颗粒太短。木屑颗粒机3,木屑颗粒由一源点产生辐射式裂纹这种状况的呈现主要缘由是木屑中含有比拟大的木屑形成的。纤维水平差不多的原料在制粒时才会使他们互相挤压互相交融,如存在较大纤维,影响了纤维之间的互相作用。他不像其它较细的原料那么容易软化,而在冷却时,由于软化水平不同,招致收缩量的差别,致使产生辐射式裂纹。
  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,程度裂纹横过整个木屑颗粒
  4. Degree cracks cross the whole sawdust grain裂纹发作于木屑颗粒的横切面,只是颗粒没有弯曲。当将含有较多纤维的疏松的木屑制粒时,有可能发作此种状况。这种木屑颗粒常常是在将木屑挤入环模的造粒孔时,由于其中含有比孔径长的纤维,当颗粒被挤出后,因纤维的收缩作用使颗粒料在横截面上产生横贯裂纹,产生枞树皮状的木屑颗粒外观。
  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.
