  木屑颗粒机水分太大太小都不能成型的缘由?经过研讨标明,原料水分过大会形成成型松懈以至不成形,再大点会直接堵住磨具不出料,而水分小了粉末多,成型差,当然这是表如今颗粒成型上的外观表现,那么从成型机理上讲木屑颗粒机水分大了小了都不能成型的缘由是什么呢?研讨标明,无论是颗粒燃料还是块状燃料,原料含水率严重影响常温成型产质量量和产量。固然针对不同的原料,适合的含水率请求稍有差异,但总体规律是分歧的。适合含水率普通在12%~18%之间,最佳含水率在15%左右。含水率小于15%左右时,燃料密度随含水率的增加呈增大趋向;含水率大于15%左右时,燃料密度快速降落,成型块外表有裂纹,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.

  关于适量水份在成型过程中的作用,研讨标明:在生物机体内存在的适量的分离水和自在水是一种光滑剂,使粒子间的内摩擦变小,活动性加强,从而促进粒子在压力作用下滑动而嵌合。
  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.
  当生物质原料的含水量过低时,粒子得不到充沛延展,与周围的粒子分离不够严密,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.

  木屑颗粒机水分太大太小都不能成型的缘由?当含水率过高时,粒子虽然在垂直于最大主应力方向上充沛延展,粒子间可以啮合,但由于原料中较多的水分被挤出后,散布于粒子层之间,使得粒子层间不能严密贴合,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.
