  木屑秸稈燃料制粒機工作原理及優點
  Working Principle and Advantage of Sawdust Straw Fuel Pelletizer
  木屑秸稈燃料顆粒機是將水分在8-20%之間的秸稈、木屑等生物質材料進行燃燒,通過造粒機壓棒和磨料擠出,將木屑、秸稈等材料制成顆粒燃料設備。
  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.
  木屑秸稈燃料顆粒擠壓顆粒燃料,密度在1.0-1.3之間,體積重量在600-650千克之間,燃燒熱值在3900-4500千卡之間,是煤的佳替代品。
  Sawdust and straw fuel particles extrude pellet fuel with density between 1.0-1.3, volume weight between 600-650 kg and combustion calorific value between 3900-4500 kcal, which is the best alternative to coal.

  木屑秸稈燃料顆粒機工作原理:
  Principle of sawdust straw fuel granulator:
  木屑顆粒機是由材料的逆轉進入禁區內的環模,這有兩個輥,輥形式限制),因為環材料倒入模具,模具旋轉輥,兩個旋轉部分之間的暴力揉捏,飼料和模孔的一部分,形狀的粒子在擁擠、顆粒擠壓模和圓柱后,終于被固定刀切成顆粒燃料。木屑顆粒機在生產過程中,受限制區域內粉料的取向不一致,壓縮輥的壓縮力也不相同。它可以分為四個區域,即進料區、沖壓區、摩擦區和成型區。
  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、木屑造粒機進給區:物料完全不受機械力的影響,處于自然松弛狀態,但受環形模圈反向轉動產生離心力的影響,使粉末靠近環形模內圈。
  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、木屑顆粒壓區:隨著模輥的轉動,物料進入壓區,在此區域,通過模輥的揉捏作用,顆粒之間的相對運動,孔隙逐漸減小。隨著物料前進速度的加快,擠壓壓力逐漸增大,孔隙變小,但粉末基本沒有變形。
  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,木屑制粒機捏面積:捏地區模具輥差距變得越來越小,捏力急劇增加,粉末進一步施壓和嵌入式,粉的增加和組合之間的接觸表面增強,粉末變形,并有良好的連接,將按粉模孔。球團進給是由一段滿壓長度通過模孔形成的。本節材料將經歷彈塑性復合變形,壓后材料密度將達到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、木屑顆粒機形成面積:在模孔中充滿了壓實形成燃料缸內的模孔,繼續承擔新的擠壓粉,使燃料缸外,排出模孔,這個時候捏力將克服的總摩擦材料列在模孔內,將擠塑成型顆粒。
  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、木屑顆粒機注意事項:物料在軋制極限下的結晶器軋制效果對顆粒有兩種條件:
  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,壓模輥將材料送入變形口。
  Firstly, the die roll feeds the material into the deformation mouth.
  第二,滾筒對材料的揉捏力大于模具孔內材料柱的摩擦阻力。因為木屑顆粒機壓桿工作溫度非常高,有合理的石油供應和熱損失的時間,可以有效地延長輥的使用壽命,增加工作輥生產的有效時間,木屑顆粒機輥擠壓負擔的材料,如木屑的內孔模具,并將前面的后面的原材料,促進原料,以達到終的目的。正式在木屑顆粒機在使用前,必須充分和合理的磨削,制造商在木屑顆粒機指令通常需要根據某些公式合理的磨環模因為木屑顆粒機輥熱處理件,熱處理過程中內孔的環模生產一些毛刺,毛刺的壓制木屑顆粒阻礙流動的材料和形狀。

  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.
