Under the premise of fixed equipment hardware structure and rated parameters, the coal quality characteristics are the primary external factor affecting the operating efficiency, service life, and failure rate of the Feeder Breaker. This article deeply analyzes the mechanism of the impact of various coal quality parameters on the performance of the Feeder Breaker equipment, and combines the on-site conditions to provide practical debugging, operation and maintenance, and equipment upgrade optimization solutions to help mining enterprises precisely solve equipment problems and achieve cost reduction and efficiency improvement.

Currently, the open-pit mining operations in major mining countries around the world generally adopt feeder breakers. Their wide application mainly stems from multiple comprehensive technical and economic advantages: relatively low initial investment and total life cycle operating costs; outstanding processing capacity per unit time, which can support high-capacity continuous production; effectively alleviating the impact load of large pieces of material on downstream conveying and crushing equipment, significantly reducing the unplanned downtime and maintenance frequency of key equipment; and having strong adaptability to working conditions and system compatibility, which can flexibly match different rock types, particle size distributions, and existing process layouts.
