Static pressure distribution of the wall is essential to the optimal characteristics and discharge stability of the powder from products (bulk solids) in a silo. A Geocomp Shear Trac-II system was used to measure the flow properties of three different types of material, with an emphasis on the determining the best results in experiments using a special test silo with conical hopper dependent on the static pressure distribution of the silo wall. Experimental results shows that with an increase in height from the outlet, the pressure in a hopper gradually increases, while the silo wall’s normal pressure in the cylinder decreases. The maximum pressure appears at the silo-hopper junction. Three different material types are chosen based on their ability to have a weakening effect on horizontal pressure. With the increase in particle size, the horizontal pressure in the silo junction remained constant. In the cylinder cross section, the larger the particle size, the higher the horizontal pressure. Meanwhile, the vertical pressure distribution shows the opposite trend. With the increase in moisture content, horizontal pressure increases, and the silo wall’s normal pressure decreases. The influence of the moisture content on the vertical pressure of the cone cross section is weak. In the cylinder cross section, the vertical pressure increases with the increase in moisture content. The experimental data created in this study can serve as a reference to guide the design of new silos as well as the maintenance tasks of established silos. This paper can serve as a reference on what silo parts must be reinforced under higher pressure during the unloading process.

壁的静压分布对于筒仓中产品（散装固体）中粉末的最佳特性和排出稳定性至关重要。使用Geocomp Shear Trac-II系统来测量三种不同类型材料的流动特性，重点在于确定使用带有锥形料斗的特殊测试筒仓和筒仓壁的静压力分布而确定的最佳实验结果。实验结果表明，随着出口高度的增加，料斗中的压力逐渐增加，而料仓壁中的筒体正常压力则降低。最大压力出现在料仓-料斗的交界处。根据它们对水平压力产生弱化作用的能力，选择了三种不同的材料类型。随着粒度的增加，筒仓枢纽的水平压力保持恒定。在圆柱横截面中，粒径越大，水平压力越高。同时，垂直压力分布呈现相反的趋势。随着水分含量的增加，水平压力增加，筒仓壁的常压降低。水分含量对锥体横截面的垂直压力的影响很小。在圆柱横截面中，垂直压力随水分含量的增加而增加。本研究中创建的实验数据可为指导新筒仓的设计以及已建立筒仓的维护任务提供参考。本文可为卸载过程中必须在较高压力下加固哪些筒仓零件提供参考。
