气力输送有几种形式,各种形式的特点是什么气力输送有吸送式、压送式、筒式、带轮集装容器式气力输送4种形式。
There are several forms of pneumatic conveying. What are the characteristics of each form? There are four forms of pneumatic conveying: suction conveying, pressure conveying, barrel conveying and roller container conveying.
1、吸送式气力输送作业范围广、移动灵活方便、可以连续供料和连续输送，能适应各种不船型的船舱卸载。
1. Suction pneumatic conveying has a wide range of operation, flexible and convenient movement, continuous feeding and continuous conveying, and can adapt to the unloading of various ship types.
2、压送式气力输送输送距离长容量大、适应范围广、易于实现输送过程的自动化控制、混合比高，耗气量少、但供料装置较为复杂要求输送管等部件的密封性要好。
2. Pressure pneumatic conveying has long conveying distance, large capacity, wide adaptability, easy to realize automatic control of the conveying process, high mixing ratio, low air consumption, but the feeding device is complex, requiring the sealing of conveying pipes and other parts to be better.
3、筒式气力输送具有低速、密相、低动力指数的特点。
3. Barrel pneumatic conveying has the characteristics of low speed, dense phase and low dynamic index.
4、带轮集装容器式气力输送机动性好、高速稳定、连续性好、具有集装化。
4. The belt wheel container pneumatic conveying has good mobility, high-speed stability, good continuity, and high-efficiency containerization.
适用气力输送的物料有哪些？
What materials are suitable for pneumatic conveying?
一般评估一种物料到底是否符合输送，需要根据物料以下几点特性分析：
Generally, to evaluate whether a material meets the transportation requirements, we need to analyze the following characteristics of the material:
1、物粒的粒径
1. Particle size
2、含水率
2. Moisture content
3、堆积密度
3. Bulk density
4、为了生产，同时还需要考虑到防爆，防静电的因素。一才是关重要。
4. In order to work safely, explosion-proof and anti-static factors should also be considered. Safety is crucial.
