  生物质颗粒机生产厂家选取原料多大粒度好?
  What size of raw materials does the biomass granulator manufacturer choose?
  木屑颗粒机在生产加工木屑颗粒时,到底木屑原料的尺寸好不好,成型无裂纹?龙腾新能源在木屑颗粒机的制造、安装、调试等方面有十多年的经验,发现木屑原料的粒度对成型有重要影响。
  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.
  生物质颗粒燃料的主要材料形式是不同粒径的颗粒。颗粒在压缩过程中的填充特性、流动特性和压缩特性对生物质的压缩成型有很大的影响。生物质压缩成型一般分为两个阶段。
  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.
  在第一个阶段,在压缩初期,较低的压力转移到生物质颗粒上,改变了之前松散堆积的固体颗粒的排列结构,降低了生物质的内部空隙。
  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.
  在第二阶段,当压力逐渐增大时,较大的生物质颗粒在压力作用下破碎,变成较细的颗粒,发生变形或塑性流动。此时,粒子开始填充空间,粒子之间的接触更加紧密,相互啮合。部分残余应力储存在成型颗粒中,使得颗粒间的粘结更加牢固。
  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.
  颗粒越小,充填程度越高,接触越紧密。当粒子尺寸足够小(几百几微米)后,形成粒子内部约束力方法和主要和次要的变化,甚至粒子之间的分子引力和静电吸引和液体附着力,毛细力)领先地位开始上升,将导致成型木屑颗粒,或形成一个不好的现象。

  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.

  木屑颗粒的不透水性和吸湿性与颗粒大小密切相关。然而,相反,由于颗粒尺寸越小,颗粒之间的间隙越容易填充,可压缩性越大,成型颗粒内部的残余内应力就越小,这就削弱了成型颗粒的亲水性,提高了不透水性。那么什么是合适的芯片尺寸呢?关北机械工程师的经验表明,1 ~ 5mm的锯末容易形成,产生的锯末颗粒外观光滑,裂纹较低。当压辊大于5mm时,压辊与磨具之间的摩擦力增大,磨具的损耗增大。由于原料颗粒过大,产生的颗粒会从较大的颗粒原料中断裂,而由于缺少与其他颗粒的咬合,几乎没有破碎的部分会出现裂纹。对小于1mm的原材料颗粒尺寸过大,会导致原材料颗粒之间的咬合不牢固,导致颗粒抗落,甚至不成形,木屑颗粒短等。
  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.
