The raw coal directly exploited from the mines must experience washing and separating before sending to the refinery and power plant for use. Because there are not only mixed with a lot of impurities in the raw coal, besides, coal quality is different, so raw coal is necessary to be separated. Coal washing can not only eliminate coal gangue and dust in the raw coal, but also remove part of surfer.
At present, most of our country's coal preparation equipment are below the international level technically, generally of traditional structure and low processing ability. But the processing volume of coal washing and separating is showing an increasing trend, so it becomes an urgent problem to further improve and promote coal dressing result.
Crushing and screening is the first link of raw coal preparation, which is very important. Raw coal is a kind of material with medium hardness and high humidity. During the crushing process, the ordinary hammer crushers are easier to be blocked and thus result in a low production efficiency and yield. Therefore, such crushing machinery with low cost, low energy consumption, high performance and high producing efficiency will become the favorite of Coal bosses.
Heavy hammer rock crusher, also known as megalith crusher, is a new generation of crushing equipment optimized on the basis of the mechanical principles of ordinary hammer crusher, vertical hammer crusher and many other similar crushers. According to the market feedback we can know that heavy hammer rock crusher is the most preferred crushing product in the current coal industry.
