En-masse conveyors

One flexible design to replace your conventional set-up. Dependable, efficient and economical

En-masse conveyors are the perfect solution for conveying virtually any free-flowing bulk material in both vertical and horizontal directions. Working simultaneously as traditional conveyors as well as elevators, en-masse conveyors have a single machine capacity of over 600 tons per hour and can withstand temperatures up to 400 degrees Celsius (900 degrees Fahrenheit), which makes them perfect for transporting any material.

One solution, many advantages

Safety & reliability

Superior safety with fewer repairs and maintenance, lower noise, less spillage and a cleaner environment.

Lower environmental impact

Retrofits and refurbishments significantly reduce raw material consumption when compared with the procurement of new equipment.

OEM quality, warranty & support

Unmatched parts quality with standard factory warranty and dedicated local support.

Better reclamation and distribution for bulk materials with en-masse conveyors

En-masse conveyors are constructed from long-wearing materials in completely enclosed and dust-tight casings and are available in both open and closed-circuit configurations. They come equipped with several inlets and outlets for ease of use but most importantly, they have self-feeding capabilities which eliminate the need for rotary valves and feeders.

Well protected

Metso en-masse conveyors are robustly constructed to ensure not only a lack of spillage, compaction or fugitive dust but also gentle handling of products and protection from external contamination. Material moves in a solid placid column providing a minimum of internal turbulence in the material.  This reduction in turbulence leads to very little degradation of material.

Low installation and maintenance costs

Casing sections are pre-assembled in a machinery factory, which makes installation at the site easy and cost-effective. Due to the high-quality materials used in production, you can be assured of the reliability and low operational costs of the machines in the long run.

Minimal space requirements

En-masse conveyors don’t need as much space as other similar equipment and can therefore be positioned economically to increase efficiency and decrease operational costs.


Thanks to the self-feeding capacity of the en-masse conveyors, they are able to replace the functionality of feeders and rotary valves so you get more operational capacity with less equipment.
