  木屑顆粒機水分太大太小都不能成型的緣由?經過研討標明,原料水分過大會形成成型松懈以至不成形,再大點會直接堵住磨具不出料,而水分小了粉末多,成型差,當然這是表如今顆粒成型上的外觀表現,那么從成型機理上講木屑顆粒機水分大了小了都不能成型的緣由是什么呢?研討標明,無論是顆粒燃料還是塊狀燃料,原料含水率嚴重影響常溫成型產質量量和產量。固然針對不同的原料,適合的含水率請求稍有差異,但總體規律是分歧的。適合含水率普通在12%~18%之間,佳含水率在15%左右。含水率小于15%左右時,燃料密度隨含水率的增加呈增大趨向;含水率大于15%左右時,燃料密度快速降落,成型塊外表有裂紋,以至不能成型。
  The reason why the moisture of sawdust granulator is too big and too small to form? After discussion, it is indicated that excessive moisture content of raw materials will result in loose forming and even shaping, and bigger points will directly block the abrasive tool from producing, while less moisture and more powder will result in poor forming. Of course, this is the appearance of particle forming, so the reason why the moisture content of wood chips granulator is too big and too small to form is that from the forming mechanism, wood chips granulator can not form. What is it? It is indicated that the moisture content of raw materials seriously affects the quality and output of normal temperature moulding, whether granular or bulk fuels. Although there are slightly different water content requirements for different raw materials, the general rules are different. The suitable moisture content is generally between 12% and 18%, and the optimum moisture content is about 15%. When the moisture content is less than 15%, the fuel density tends to increase with the increase of the moisture content; when the moisture content is more than 15%, the fuel density drops rapidly, and there are cracks on the surface of the forming block, so that it can not be formed.

  關于適量水份在成型過程中的作用,研討標明:在生物機體內存在的適量的分離水和自在水是一種光滑劑,使粒子間的內摩擦變小,活動性加強,從而促進粒子在壓力作用下滑動而嵌合。
  As for the role of proper moisture in the forming process, the study indicates that the proper amount of separated water and free water in the organism is a kind of smoothing agent, which reduces the internal friction between particles and enhances their mobility, thus promoting the sliding and chimerism of particles under the action of pressure.
  當生物質原料的含水量過低時,粒子得不到充沛延展,與周圍的粒子分離不夠嚴密,所以不能成型;
  When the moisture content of biomass raw materials is too low, the particles can not be fully extended and separated from the surrounding particles, so they can not be formed.

  木屑顆粒機水分太大太小都不能成型的緣由?當含水率過高時,粒子雖然在垂直于大主應力方向上充沛延展,粒子間可以嚙合,但由于原料中較多的水分被擠出后,散布于粒子層之間,使得粒子層間不能嚴密貼合,因此不能成型。
  The reason why the moisture of sawdust granulator is too big and too small to form? When the water content is too high, although the particles extend abundantly in the direction perpendicular to the maximum principal stress and mesh among particles, the particles can not be formed because of the more water in the raw material is extruded and dispersed among the particles, which makes the particles can not be closely adhered to each other.
