What is the Functional Difference Between a Drag Chain and En-Masse Conveyor?

Efficient Operating Principle of Drag Conveyors

Hapman offers the most durable, efficient drag conveyors in the industry. They are manufactured to effectively move material over distances of 20 feet up to 200 feet or more.

Built with the industry’s most durable chain, Hapman’s line of drag conveyors provides the highest level of abrasion resistance all while reducing the chance of stress and breakage from occurring.

If you’re interested in learning more about our line of drag conveyors, don’t hesitate to reach out to Hapman today. In our most recent blog, Hapman discusses the fundamental differences between drag chain conveyors and En-Masse Drag Chain Conveyors.

How Does a Drag Chain Conveyor Operate?

The principle operation of a drag chain conveyor is based on material movement using a skeletal chain and flight assembly that is drawn along the bottom section of an enclosed housing. Drag conveyors are an optimum choice for bulk processors, power producers, cement manufacturers, and minerals processors for conveying efficiency and enclosed housing.

Unlike a belt conveyor, a drag conveyor uses nearly 50% of the available space inside the conveyor housing for material movement, while a belt conveyor only uses about 20%. This means that a greater volume of material can be moved in a smaller housing at slower speeds and with less horsepower. Slower chain speed means less wear, and less horsepower equals lower energy requirements and operating costs.

The team at Hapman will work with you to select the specific features that are required for your company’s application. Some of the features can include the conveyor size, flight selection, housing, high-temperature components, diverting discharge points, and single- or dual-chain layout.

How Does an En-Masse Drag Conveyor Operate?

En-Masse drag conveying works by pulling a single strand of endless chain centered in an enclosed housing with flights attached on both sides of the chain (skeletal looking) through a rectangular section of a bulk solid material.

The bulk solid is conveyed by the motion imparted on the bottom surface of the trough by the chain and the shear friction between the particles of the bulk solid material conveyed. The En-Masse drag conveyor is not limited to conveying En-Masse; there are many applications where the bulk solids capacity that is required or the conveyor configuration isn’t practical, but in a lot of these cases the single-chain strand with skeletal flights is a very good and reliable solution for conveying needs. In other words, EnMasse drag conveying is one type of operating principle of a drag conveyor.

With an En-Masse Drag Conveyor, you’ll have the ability to move large volumes of bulk materials in any layout or direction, providing exceptional flexibility to achieve all of your bulk material handling objectives.

Some of the benefits of these versatile conveying systems include:

  • Moving up to 1,000 TPH in a single system.
  • Using the longest-wearing, drop-forged chain in the industry.
  • Conveying a wide range of materials from ash to zinc.
  • Conveying in an enclosed, long-lasting, abrasion-resistant housing.
  • Conveying high volumes in a small footprint.
