To calibrate coal mill feeders, you need to accurately measure the feed rate of the coal and make adjustments as needed. This can be done by monitoring the pressure head of the mill, inspecting the feeder for any wear and tear, and using tools such as a speedometer or tachometer to verify the feed rate. Additionally, you may need to adjust the chain drive speeds in order to ensure that the coal is being fed into the mill at the correct rate.
Calibrating coal mill feeders involves setting the feed rate of the mill to match the capacity of the coal mill. This can be done in a number of ways, but some common methods include:
Manual calibration: This involves adjusting the feed rate manually using a control valve or other manual control mechanism. This method is simple, but it can be time-consuming and may not be accurate.
Automatic calibration: This involves using sensors and control systems to automatically adjust the feed rate based on real-time measurements of the coal mill's capacity. This method is more accurate and efficient, but it requires the installation of additional equipment.
To calibrate the coal mill feeder, follow these steps:
Measure the coal flow through the mill. This can be done using a flow meter or by collecting a sample of the coal and weighing it.
Compare the measured coal flow to the desired flow rate. If the measured flow is higher than the desired rate, reduce the feed rate by adjusting the control valve or other manual control mechanism. If the measured flow is lower than the desired rate, increase the feed rate.
Continue adjusting the feed rate until the desired flow rate is achieved. This may require several iterations.

Once the desired flow rate is achieved, fine-tune the feed rate as needed to ensure that the coal mill is operating at optimal capacity.
It is important to note that the calibration process may need to be repeated periodically to account for changes in the coal mill's capacity or changes in the properties of the coal being used.
