DPG-B-Series-ConveyorOur DPG-B Series conveyor features a gravity-loaded, bottom-discharge transfer with a 400+ TPH capacity for high-demand jobs. It provides a high material-to-air ratio and intermediate line velocities, thereby resulting in smaller line sizes, lower air consumption, fewer dust problems and reduced energy costs. Abrasive wear and particle degradation are also minimized. Standard units are ideal for in-plant transfer of most powdered, granular, abrasive, or pelletized materials, and even have the ability to successfully transfer materials over long distances.
Standard DPG Series conveyors use efficient gravity force to load and high-pressure air to convey. During the load cycle, dual inlet valves open to allow material to flow by gravity into the tank from one or more supplies sources, such as storage silos. The purge valve opens, venting displaced air down the convey line. When the tank is full, the inlet valves close to stop the flow of material. Multi-point injection then pressurizes the tank to the discharge set point and the discharge valve opens, allowing the material to enter the convey line.
Because the air-to-material ratio is regulated in the tank, line injectors are not required. When the tank is empty, the conveying air is shut off and the pressure remaining in the tank clears the remaining slug of material from the convey line.
DPG systems are also available in a dual-tank model. The Dual DPG Series Conveyors operate in a near continuous dense phase mode with one tank available to fill product, while a second tank conveys it.
