  木屑秸秆燃料制粒机工作原理及优点
  Working Principle and Advantage of Sawdust Straw Fuel Pelletizer
  木屑秸秆燃料颗粒机是将水分在8-20%之间的秸秆、木屑等生物质材料进行燃烧,通过造粒机压棒和磨料挤出,将木屑、秸秆等材料制成颗粒燃料设备。
  The sawdust straw fuel granulator combusts biomass materials such as straw and sawdust with moisture between 8-20%, and extrudes sawdust and straw into granular fuel equipment by pressing bars and abrasives of the granulator.
  木屑秸秆燃料颗粒挤压颗粒燃料,密度在1.0-1.3之间,体积重量在600-650千克之间,燃烧热值在3900-4500千卡之间,是煤的最佳替代品。

  木屑秸秆燃料颗粒机工作原理:
  Principle of sawdust straw fuel granulator:
  木屑颗粒机是由材料的逆转进入禁区内的环模,这有两个辊,辊形式限制),因为环材料倒入模具,模具旋转辊,两个旋转部分之间的暴力揉捏,饲料和模孔的一部分,形状的粒子在拥挤、颗粒挤压模和圆柱后,终于被固定刀切成颗粒燃料。木屑颗粒机在生产过程中,受限制区域内粉料的取向不一致,压缩辊的压缩力也不相同。它可以分为四个区域,即进料区、冲压区、摩擦区和成型区。
  The sawdust granulator is a ring die which reverses the material into the forbidden zone. There are two rolls and the form of roll is limited. Because the ring material is poured into the die, the rotating roll of the die, the violent kneading between the two rotating parts, the part of feed and die hole, the shaped particles are finally cut into pellet fuel by a fixed knife after being crowded, pellet extrusion die and cylinder. 。 In the production process of sawdust granulator, the orientation of powder in the restricted area is different, and the compression pressure of the compression roll is also different. It can be divided into four areas, namely, feed area, stamping area, friction area and forming area.
  1、木屑造粒机进给区:物料完全不受机械力的影响,处于自然松弛状态,但受环形模圈反向转动产生离心力的影响,使粉末靠近环形模内圈。
  1. Feed zone of sawdust granulator: Material is completely free from mechanical force and in a state of natural relaxation, but influenced by centrifugal force produced by reverse rotation of ring die ring, which makes powder close to inner ring of ring die.
  2、木屑颗粒压区:随着模辊的转动,物料进入压区,在此区域,通过模辊的揉捏作用,颗粒之间的相对运动,孔隙逐渐减小。随着物料前进速度的加快,挤压压力逐渐增大,孔隙变小,但粉末基本没有变形。
  2. Sawdust particle pressing area: With the rotation of the die roll, the material enters the pressing area. In this area, through the kneading action of the die roll, the relative movement between the particles, the porosity gradually decreases. With the acceleration of material advancing speed, the extrusion pressure increases gradually and the pore size decreases, but the powder basically does not deform.
  3,木屑制粒机捏面积:捏地区模具辊差距变得越来越小,捏力急剧增加,粉末进一步施压和嵌入式,粉的增加和组合之间的接触表面增强,粉末变形,并有良好的连接,将按粉模孔。球团进给是由一段满压长度通过模孔形成的。本节材料将经历弹塑性复合变形,压后材料密度将达到1.1-1.3g/cm3左右。
  3. Kneading area of sawdust granulator: the gap between die rolls in kneading area becomes smaller and smaller, the kneading force increases sharply, the powder is further pressed and embedded, the contact surface between the increase and combination of powder is strengthened, the powder is deformed, and has good connection, which will be according to the powder die hole. The pellet feed is formed by a full pressure length passing through the die hole. The material in this section will undergo elastic-plastic composite deformation, and the material density will reach 1.1-1.3g/cm3 after pressing.
  4、木屑颗粒机形成面积:在模孔中充满了压实形成燃料缸内的模孔,继续承担新的挤压粉,使燃料缸外,排出模孔,这个时候捏力将克服的总摩擦材料列在模孔内,将挤塑成型颗粒。
  4. Formation area of sawdust granulator: The die hole is filled with compaction to form the die hole in the fuel cylinder, and the new extrusion powder is continued to be assumed, so that the fuel cylinder is discharged from the die hole. At this time, the total friction material overcome by pinching force will be arranged in the die hole, and the extruded particles will be formed.

  四、木屑颗粒机注意事项:物料在轧制极限下的结晶器轧制效果对颗粒有两种条件:
  4. Notices for sawdust granulator: There are two conditions for the effect of crystallizer rolling under the rolling limit of materials on particles:
  首先,压模辊将材料送入变形口。
  Firstly, the die roll feeds the material into the deformation mouth.
  第二,滚筒对材料的揉捏力大于模具孔内材料柱的摩擦阻力。因为木屑颗粒机压杆工作温度非常高,有合理的石油供应和热损失的时间,可以有效地延长辊的使用寿命,增加工作辊生产的有效时间,木屑颗粒机辊挤压负担的材料,如木屑的内孔模具,并将前面的后面的原材料,促进原料,以达到最终的目的。正式在木屑颗粒机在使用前,必须充分和合理的磨削,制造商在木屑颗粒机指令通常需要根据某些公式合理的磨环模因为木屑颗粒机辊热处理件,热处理过程中内孔的环模生产一些毛刺,毛刺的压制木屑颗粒阻碍流动的材料和形状。

  Secondly, the kneading force of the drum on the material is greater than the friction resistance of the material column in the die hole. Because the working temperature of the pressing rod of the sawdust granulator is very high and there is reasonable oil supply and time of heat loss, it can effectively prolong the service life of the roll, increase the effective time of the production of the working roll, and extrude the burden material of the roll of the sawdust granulator, such as the inner hole mould of sawdust, and promote the raw material in front and behind, so as to achieve the final result. Purpose. Before the sawdust granulator is used formally, it must be grinded sufficiently and reasonably. The manufacturer's instructions in sawdust granulator usually need to grind the ring die reasonably according to some formulas because the ring die of the inner hole of the sawdust granulator roll produces some burrs in the heat treatment process. The pressing sawdust particles of burrs hinder the flow of materials and shapes.
