We are Manufacturer, Supplier, Exporter of Pneumatic Conveying Systems and our setup is situated in Pune, Maharashtra, India. If the material is conveyed in suspension in the air through the pipeline it is referred to as dilute phase conveying. If the material is conveyed at low velocity in a non-suspension mode, through all or part of the pipeline, it is referred to as dense phase conveying
A. Dilute phase Almost any material can be conveyed in dilute phase, suspension flow through a pipeline,regardless of the particle size, shape or density. It is often referred to as suspension flow because the particles are held in suspension in the air as they are blown or sucked through the pipeline. A relatively high velocity is required and so power requirements can also be high but there is virtually no limit to the range of materials that can be conveyed. There will be contact between the conveyed material and the pipeline, and particularly the bends, and so due consideration must be given to the conveying of both friable and abrasive materials. With very small particles there will be few impacts but with
large particles gravitational force plays a part and they will tend to 'skip' along horizontal pipelines.
Types of Pneumatic Conveying systems in a Dilute Phase
There are several methods of transporting materials using pneumatic conveying system. In general, they seem to fall into three main categories : dilute phase, dense phase, and air conveying.
1. Dilute-phase pneumatic conveying system is the process of pushing or pulling air-suspended materials from one location to another by maintaining a sufficient airstream velocity. Dilute phase conveying is essentially a continuous process, characterized by high velocity, low pressure and low product to air ratio.
2. Dense-phase conveying system relies on a pulse of air to force a slug of material from one location to another. Dense-phase system is essentially a batch process, characterized by low velocity, high pressure and high product to air ratio unlike dilute phase which is a low product to air ratio.
