Dedusting and Dust Collection It is generally accepted that no method of coal cleaning except froth flotation is effective in cleaning dust In the majority of coals mined in the United States the dust sizes contain a high percentage of impurities hence the removal of the dust from the coarse sizes lowers the impurity content of these sizes

There are three ways to minimize dust in a samll size particle distribution beyond sprays using 1 Luffing head frame similar to many stackers which keeps the fall height to a minimum 2 Telescoping chute as used in ship loading to limit the exposure to cross winds and which may also use a flow constrictor to minimize gas in the material stream

To calculate the correct gas flow for venting the discharges of the lime kilns onto the 2 ft 61 cm wide conveyor belts the following calculation was used 2 ft width of belt x 500 cfm/ft 700 cfm = 1 700 cfm Compensating for altitude Note that the preceding equation is valid for standard conditions 70°F = 21°C at sea level

This line will help in sending the material to its discharge point Then comes the role of Lime Dust Collector that will separate out the fluidized lime and the air The air is then blown outside after making it clean Finally the Lime Discharge Rotary Airlock Valve does its job of discharging the lime out of the dust collector

Another common way of controlling dust is with the addition of water By adhering to the dust particles clumping them together and increasing the weight water quickly supresses the dust slowing its projection velocity and causing it to lose momentum allowing it to fall into the material flow

TECHNIQUES FOR CONVEYOR DUST CONTROL Some material handling operations use dust suppression techniques — water sprays in particular — to remove particulates from the air and keep them on the material being conveyed These active dust control methods are costly to run may require water treatment and leave the material being conveyed wet

The principle of pneumatic conveying is based on the fact that bulk goods can be moved by means of air through pipelines The flowing conveying air transmits a propulsion force on the bulk material and thus conveys it through the conveying line The pneumatic conveying always requires a pressure difference between the beginning and the end of

The level of lime in the coolers is controlled to maintain given levels and thus given volumes of lime Lime is discharged at the bottom of the coolers by means of a discharge plow mechanism and on to conveyor belts and transferred to storage silos The temperature of the lime when discharged to the conveyor belts is approximately 250°F
