Feeder Breaker a Powerful Tool For Primary Crushing Of Coal In Open-Pit Mines
Feeder breaker is a widely used crushing equipment in open-pit coal mining. Open-pit coal mining, as the name suggests, is a method of mining that can be carried out directly from the surface rather than by digging shafts underground. It is also a technology, a surface mining technique for extracting rocks or minerals from open-pit mines. This mining method is widely used not only in china but also around the world.
This form of mining is different from the traditional method of digging tunnels underground. Generally, when commercially valuable ore or rock deposits are found near the surface, this mining method is employed. If there are ore resources near the surface, the relatively thin overburden makes it unsuitable for tunneling. Coal, sand, and gravel are common examples of such situations.
Feeder breaker is a specialized equipment for the initial crushing, feeding, and conveying of materials in open-pit coal mines. The live tooth heads installed on the crushing unit’s toothed rollers, developed by our company, are specifically designed to address the issues of large grinding, slow replacement, and troublesome replacement in open-pit coal mines. The feeder breakers produced by our company, equipped with live tooth heads, have been widely used in domestic regions such as Xinjiang and inner Mongolia, and have also been deployed in dozens of units in countries like Indonesia and Mongolia. The material of these live tooth heads is mainly alloy, which enhances their wear resistance and hardness, prolonging the service life of the entire toothed roller. Our alloy live tooth heads undergo self-inspection in the factory and are also subject to strict quality inspections by third-party quality inspection institutions such as sinopec in china to ensure their hardness and material quality, thereby safeguarding the interests of our customers, extending the service life of the feeder breaker, reducing the cycle and time for replacing wear parts, minimizing downtime, and ensuring the continuous operation of the equipment at the customer’s site.
Forty percent of the world’s coal production is achieved through open-pit mining. In china, there are also many open-pit coal mines, such as the holiness coalfield in ganglion city, inner Mongolia, which is one of the top-producing open-pit coal mines in china, with proven reserves of approximately 13.3 billion tons. Inner Mongolia has four major open-pit mines.
In summary, compared to underground coal mining, also known as shaft mining, open-pit mining offers higher productivity, lower production costs, and safer and healthier working conditions. The biggest challenge in open-pit mining is the need to remove the overburden from the surface, which may take longer than digging shafts.
Our feeder breaker can be combined with other upstream and downstream equipment to form a mobile crushing station, which facilitates the mobility of the equipment in open-pit coal mines, saves customers’ reconstruction costs, and improves their economic benefits.
