With the development of technology, there are more and more ways to transport materials. However, for the transportation of powdered materials through belt conveyors and pipe chain conveyors, it is inevitable to encounter dust flying around, causing the workshop environment to be ravaged by flying dust, giving people a dirty and chaotic production environment, and losing some customers. Some materials have a risk of flammability, and dust explosions may occur when the material and air reach a certain concentration.

       pneumatic conveyingIt is a technology that uses air flow as a carrier medium to transport particles and powdered materials under certain conditions. At present, the most commonly used pneumatic conveying methods are suction conveying and pressure conveying. Their main mechanism is based on the effect of airflow with a certain velocity on material particles. According to many experimental analyses, hydrophilic motion is the main mode of motion for air and material mixtures, which determines the entire interaction between the airflow and material particles through the system flow effect. In other words, the airflow cannot transport materials in a laminar state. The current mainstream conveying methods are positive pressure conveying and negative pressure conveying, also known as pressure conveying and suction conveying

    The material particles in the airflow are transported by the total force of the air, and the total force must reach a certain amount. For example, the force and synthesis torque acting on the particles in a vertical pipe must make the particles suspended, and in a horizontal pipe, the material particles can move along the bottom of the pipe.

       According to production practice, if the selected airflow velocity can keep the material particles suspended in a vertical tube, then it can also meet the condition of material movement along the bottom of the tube in a horizontal tube. Due to the complex motion state of two-phase flow in horizontal pipes and the lack of sufficient computational data, the current selection of airflow velocity is based on the suspended velocity in vertical pipes.
