Nov 30, 2016· The measurement of coal flow is done by using load cell. For dust suppression system the spray header will be on when the contact of under belt switch is true and motor is in on. This two no of sensing is taken to avoid spraying when conveyor is not rotating but contact of under belt switch is true due to coal is laying on belt.
coal haul distance averaged 275 miles for all modes, with values ranging from 1 to 1,800 miles. 16 The average coal hauling cost was per net tonmile with costs ranging from per net tonmile, as shown in Table 41.

Definition: What is a Belt Conveyor? One of the basic tools in material handling industry, belt conveyors are most commonly used in transportation of bulk materials (grain, salt, coal, ore, sand, etc.). Belt conveyor systems consist of two or more pulleys ( drums). An endless loop of carrying medium—the conveyor belt— rotates about them.
Conveyors are seen on virtually all in the Coal Handling Plant (CHP). CHP are having number of conveyors. The control systems used for these conveyors are important for operating safe plant. Basically conveyors are dumb, but once equipped with proper control system they yield efficient and safe plant operation. Electronic
