Dense phase pneumatic conveying system

DENSE PHASE CONVEYING Efficient material transport whilst preserving quality Dense phase pneumatic conveying systems for powder transfer are used when the product quality is of the highest importance. They minimise changes in bulk density and particle size distribution and also limit demixing effects, and can be used for many materials such as powders, granules, flakes and pellets. The absence of rotating parts in pressure vessels reduces maintenance costs. The advantageous ratio of product to conveying gas also makes our systems energy efficient. Absolutely dust tight Pressure vessels are utilised within dense phase conveying systems to introduce the bulk solids into the pipeline. Contrary to when using rotary valves, the system has no leakage and is absolutely dust tight. This allows a high pressure range from 1 barg up to 6 barg, or more. The high loading and low velocity lead to gentle conveying and to low wear of both pipeline and receiver. With dense phase conveying systems, the transport of bulk solids is possible from short distances right up to long distances of several hundred meters. Your benefits • Very gentle handling of fragile products • Minimised wear of pipeline and bends • Minimised demixing of mixed products • Absence of rotating parts eliminates the danger of metal contamination and reduces maintenance costs • Gas and dust tight system with no leakage air • High solids loading leads to smaller pipe diameter and low gas consumption • Long conveying distances, up to 500 m or more, and capacities up to 150 m3/h • Ready to use graphical pneumatic conveying controller, STP 61 Applications • Gentle conveying of instant products from spray drier
