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.

Open-pit coal mining is a special working environment and is widely present in domestic and international markets. In previous crushing systems, a portable simple crushing station consisting of hammer break and vibrating feeder was commonly used for crushing. However, recently, both domestic and foreign markets have been gradually replacing the small crushing stations composed of hammer break with large crushing stations composed of feeder breaker and mineral sizer. The reason for this situation is mainly influenced by the following factors:

The feeder breaker produced by our company mainly adopts four combination forms. One is composed of a scraper conveyor and a hammer crushing unit, another is composed of a scraper conveyor and a gear crushing unit, and the third is composed of a heavy-duty apron feeder and a hammer crushing unit as well as a heavy-duty apron feeder and a gear crushing unit. It is widely applied in industries such as coal and mining.
