Product Description
Pneumatic conveying is a technology integrated system that utilizes air (or gas) flow as the conveying power to convey bulk solid materials in pipelines.
Characteristics of pneumatic conveying
(1)Simple equipment, compact structure, small footprint, flexible configuration of the conveying pipeline, so that the factory production process is more reasonable.
(2) conveying system is completely closed, less dust flying, can realize the environmental requirements
(3)less moving parts, easy maintenance, easy to achieve centralized control of the entire system and program automation
(4)high efficiency of bulk material conveying, reduce the cost of packaging and handling and transportation
(5) It can avoid moisture, dirt and other sundry materials being conveyed, and ensure the quality of conveyance.
(6) A variety of processes can be realized simultaneously in the conveying process, such as mixing, crushing, grading, drying, cooling, dust removal and other preparatory processes, but also certain chemical reactions
(7) can be concentrated by the number of points of the material transported to a place or from a place to the number of points scattered, and to achieve long-distance operation
(8) for chemically unstable materials, you can use inert gas transportation
2.Classification of pneumatic conveying
There are various ways to categorize pneumatic conveying, and among these, two are commonly used:
1. According to the dense degree of materials in the pipeline, it can be divided into: thin-phase conveying, medium-phase conveying and dense-phase conveying.
Dilute-phase conveying: conveying pressure is relatively low and stable, with the increase of air speed and rise, the material-gas ratio is generally low.
Dense-phase conveying: higher conveying pressure, low gas velocity, can realize high material-gas ratio conveying. 2. According to the airflow formed in the pipeline, it can be divided into three major categories: suction-feeding, pressure-feeding and composite. No matter how many forms of pneumatic conveying devices today, can be categorized into suction-feeding, pressure-feeding type of these two categories
