In Conveying
This section presents typical problems encountered in the conveying of bulk solids, and lists possible solutions to each one. Among the variables that must be considered in the solution to any specific problem are:
- Width, speed, and type of belt.
- Material characteristics (including moisture content and particle size).
Material leaks out of the skirted area of my belt conveyor.

 | MARTIN® Gravity Take-Up KitThe MARTIN® Gravity Take-Up Kit is installed with the conveyor's existing take-up pulley. It is available in "Narrow" for belts 48 inches (1200 mm) and under with standard stringer width or "Wide" for belts 54 inches (1400 mm) and up with wide stringer width and for take-up travel distances of 20, 40, or 48 feet (6.1, 12.2, or 14.6 m). The kit features low-friction UHMW inserts that allow the pulley to move up and down easily without binding to stabilize belt tension. |

My transfer point creates too much dust.
 | MARTIN® Dust BagsRelieve Positive Pressure And Prevent The Escape Of Airborne Dust Without the Need for "Baghouse" Dust Collection MARTIN® Dust Bags are a passive dust collection system using a filter bag to vent positive air pressure to maintain dust control. Installed before the chute end to vent air and collect dust traveling in that air, MARTIN® Dust Bags allow high positive-pressure air to escape without carrying dust away from the transfer point. When positive air pressure from material flow stops, MARTIN® Dust Bags collapse, dislodging collected material back onto the conveyor belt. |
 | MARTIN® FOG Dust Suppression SystemDust Suppression Systems Control Airborne Particles Control airborne dust economically and effectively with low-moisture fog or surfactant dust management technology. The MARTIN® FOG Dust Suppression System forces water through ultra-fine nozzles to supply a microscopic mist that merges with airborne dust to return dust particles to the main material stream. Each system is custom engineered to match your operating requirements. |
 | MARTIN® Insertable Dust CollectorFilters Inside Transfer Point Collect Dust Without Ductwork Rather than carry dust-laden air to a central dust collector, the MARTIN® Insertable Dust Collector System filters the air inside the transfer point. MARTIN® Insertable Dust Collectors can be used as stand-alone dust collector systems, or to supplement existing central dust collection systems. The MARTIN® Insertable Dust Collector can effectively handle the heavy concentration of dust and high volumes of air arising at belt conveyor transfer points. |
