BELT CONVEYOR MAINTENANCE AND TROUBLE SHOOTING INTRODUCTION There are keys to successful preventive maintenance that can be summed up in two words, "Good Housekeeping". Good belt conveyor and idler maintenance begins with "Good Housekeeping", the master key to getting the highest return on your conveyor dollar.
Results showed that during an average daily run of 4,297 tons of coal, the conveyors would lose over 7,614.637 grams (16.75 pounds) of dust. This represents a loss of 1.810 grams per ton (Table 1). 4.

Fog droplets attach to like size airborne dust particles. The slightly wetted particles agglomerate to other particles, adding enough mass to settle the dust back into the conveyed product within the covered transfer point. This is used at crushers, screens, coal yard & plant conveyors, including reclaim, gallery, tripper conveyors and silos.
A coal mining facility in China was experiencing dust and spillage from one of its conveyors. Fugitive dust lowered the air quality, clogged equipment and had the potential to affect workers' health. Misalignment of the belt caused piles of lost product that had to be cleaned up, reducing system efficiency and wasting labor hours.
Three dense-phase, low velocity pneumatic conveying systems were supplied to convey coal dust between 1.5t/h and 2.7t/h over a distance of 525ft horizontal and 30ft vertical. The systems were 2 x 3ft 3 and a single 8 ft 3 vessel all with a 3" convey pipe line. All pneumatic conveyors are located under a feed hopper with start and stop ...

The Dust Suppression System is meant to suppress the coal dust generated during transfer of coal at feed/discharge points of conveyors in various transfer towers. There are several existing methods of controlling dust but many are ineffective, costly and have detrimental effects on plant and machinery.
The movement of conveying crushed stone, coal, or sand, stirs up and creates a dust cloud, which can be suppressed by spraying water as a fine mist or fog. Adding finely sprayed water to the minerals or aggregates on conveyors or at transfer points and hoppers can prevent the generation of dust or suppress created dust clouds and keep them from ...
