Dense phase conveying systems are designed for applications where product quality is paramount. Whether handling powders, granules, flakes, or pellets, Gericke’s dense phase conveying technology ensures minimal changes in bulk density and particle size distribution, while also reducing the risk of demixing. This makes them ideal for industries requiring gentle handling of fragile or blended materials. A key advantage of the system lies in its use of pressure vessels without rotating parts. This significantly reduces maintenance requirements and eliminates the risk of metal contamination. The systems are completely dust-tight, offering a clean and safe solution with no leakage—unlike rotary valve systems used in dilute phase conveying. Operating at pressures of up to 6 barg, they enable high solids loading and low gas consumption. This translates into energy efficiency and reduced operational costs.
For a range of different industrial needs
Gericke’s dense phase systems are capable of conveying materials over distances of up to 500 metres and at capacities reaching 150 m³/h. They are available in carbon steel or stainless steel, with vessel volumes ranging from 20 to 5,200 litres, and comply with PED 2014/68/EC, ASME, and GB 150 standards. This flexibility makes them suitable for a wide range of industries, including food, chemical, and raw material processing. The systems support a variety of applications, from gentle transfer of spray-dried products to demixing-free transport from mixers to filling lines, and even direct reactor loading. They also accommodate batch weighing, high-capacity handling, inert gas conveying, and gentle unloading from trucks or railcars.
Gericke offers three conveying modes tailored to specific needs: the “DenseFlow” PHF system for continuous layer transport at moderate gas velocities, the “PulseFlow” PTA system for pulsed plug conveying at low velocities, and the “PulseLine” PTA PL system, which enhances long-distance conveying with external air injectors for maximum process safety. With the addition of the Gericke GUC -C controllers, these systems are not only powerful but also user-friendly, offering intuitive operation, precise control and link to SCADA systems.
