working principle:

The process of sample accumulation, avalanche, surface morphology, and volume changes in a rotating drum is captured in real-time by a camera and analyzed and processed in real-time by software to establish a data graph and model for analyzing the flowability of particles

Definition and method characteristics description of drum method:

The drum method refers to filling a drum with powder particles and slowly rotating it, measuring the number of times the particles collapse per rotation at a fixed speed. The larger the number of times, the better the flowability; On the contrary, the smaller the size, the poorer the liquidity. This method reflects the stability, critical transition, and collapse scale of particle flow And mass flow rate

The surface of particles in the drum can be divided into three regions from top to bottom due to different flow velocities: sparse flow zone, dense flow zone, and creep zone; The variation of shear rate has a significant impact on the flow characteristics and motion state of particles;

The movement characteristics of particles in a drum can be roughly divided into two regions: the flowing surface layer and the stationary bottom layer, which unify the entire process of particle matter from a stationary state to flow, and then from flow to stillness through blockage. By adjusting the rotational speed of the drum, the flow process and flow state of particles can be obtained

Based on the thickness of the particle flow layer or the inclination angle of the free surface in the drum, the shear rate of the flow layer is obtained, and then the flowability of the particle material is calculated The shear deformation rate of particles in the dense flow area from the center to the free surface under different rotational speeds and drum diameters exhibits linear variation characteristics. The average shear rate reflects the average shear deformation ability of particle flow, and is influenced by factors such as particle size, shape, friction coefficient, and flow state.
