In the thermal power plants maximum requirements of fuel is a coal. Coal handling plant (CHP) is the main and major key system to transfer ton of coal fuel to the boiler plant. The handling of this fuel is a great job. The coal has to size, processed, and handled which should be done effectively and efficiently. Because of this CHP management
Straightforward installation into existing plants. Installing new sampling systems into existing material handling infrastructure can sometimes be a massive challenge – especially when finding enough height to install a falling stream sampling device. Cross belt samplers can be easily and inexpensively retrofitted to existing conveyor systems.
