Abstract: This paper compares the working principles and performance of disc feeders and 
electromagnetic vibrating feeders in the coal preparation system of Qian’an Zhonghua Coal Chemical Company. It also analyzes how climatic conditions, moisture and coal quality affect the accuracy of coal blending and the qualification rate of feeding. It suggests that keeping the moisture of a single type of coal in the silo below 15% can ensure a coal blending accuracy above 90%，which can improve the coal blending quality and reduce the operating cost.

Key words: Disc feeder, Electromagnetic vibrating feeder, Coal blending accuracy, Feeding ,
 , qualification rate, Moisture
