粒料低速气流输送系统（密相）
一种正压气力输送系统。采用压缩空气作为输送动力。一个高压的旋转阀作为物料的加入装置。 低速的输送气流速度可以减少物料之间以及物料和管道之间的摩擦，进而保护物料不受损。适应于粒料。
▲防止物料产生粉尘与拉丝现象;
▲适应于易碎物料;
▲**程度减少物料的高度摩擦;
▲典型应用于塑料颗粒的输送.特别是聚丙烯和聚酯塑料的应用。
特点
气力速度低、无灰尘、摩擦少、无拉丝现象产生、塑料颗粒不会被破坏。

Particle low-speed airflow conveying system (dense phase)
A positive pressure pneumatic conveying system. Using compressed air as the conveying power. A high-pressure rotary valve is used as the material addition device. Low speed conveying airflow can reduce friction between materials and between materials and pipelines, thereby protecting materials from damage. Suitable for granular materials.
▲ Prevent the generation of dust and wire drawing phenomenon in materials;
▲ Suitable for fragile materials;
▲ * * Reduce the high friction of materials to a certain extent;
▲ Typical application for conveying plastic pellets Especially the application of polypropylene and polyester plastics.
characteristic
Low pneumatic speed, no dust, low friction, no wire drawing phenomenon, and plastic particles will not be damaged.
