Large loads moved with vacuum loaded conveyors.

The DPV-T Series conveyor is a vacuum loaded, top discharge dense phase conveyor that is said to fit where restricted headroom or multiple sources make other types of pneumatic conveyors impractical. DPVT conveyors are used for bulk unloading, in-plant transfer, weighing and batching, or can be customized for almost any dense-phase conveying applications. Standard units can handle transfer rates of 100+ tons per hour and provide high material-to-air ratios and extremely low line velocities, resulting in smaller line sizes, lower air consumption, reduced dust at the discharge, and lower capital investment and operating costs, according to the company. Abrasive wear and particle degradation also are said to be minimized. DPV-T conveyors are said to be ideal for moving large quantities of powdered or fine granular materials that are abrasive or friable.

DPV Series conveyors use only positive air pressure for both loading and conveying, eliminating the need for a vacuum pump, according to the manufacturer.

A proprietary venturi assembly creates the vacuum needed for loading. In vacuum mode, the conveyor fills its transfer vessel by drawing material from one or multiple supply sources, such as storage silos, bins, hopper-bottom railcars, or trailers. A high-level switch senses when the transfer vessel is full and the programmable logic controller (PLC) automatically switches the valves to discharge mode and pressurizes the vessel for conveyed material to its destination. Integral dust separation minimizes venturi wear, according to the manufacturer. The PLC control is said to permit reduced supervision and can be easily adapted for highly automated facilities. Unit construction choices include carbon steel, stainless steel and epoxy coating. Multiple inlets and load cells are optional.

This company is a manufacturer of bulk material handling systems and controls, specializing in pneumatic conveying.
