Crushing technology is an important link in the field of industrial mineral processing, so the crusher has become a very widely used equipment in mining machinery. mineral sizers crusher is one of the most widely used crushing machines nowadays. Coal industry as the most widely used mineral sizers crusher industry, its growth also witnessed the development of mineral sizers crusher.
The oldest crusher is the roller crusher appeared in 1806, is the predecessor of tooth roller crusher. At that time, the roller crusher is simply divided into single roller crusher, roll crusher. Roll crusher is also known as roll machine, roll crusher, double roll crusher, double roll crusher. It requires raw material particle size less than 80mm, finished product particle size between 50 mesh -20mm. Ceramics, pebbles, fine iron ore as raw materials for processing are no problem. Because of its small size and simple structure, it is easy to maintain and has been used in the coal mine industry to this day.
With the development of coal industry, the simple roller crusher has been unable to meet the increasing mining difficulty and coal market demand. So the mineral sizers crusher came into being. Compared with the traditional roll crusher, mineral sizers crusher specifications are larger, the smallest type of single tooth roller crushing machine weight is also about 3 tons. In this way, it can meet the crushing demand of raw coal of coal preparation plant or large coal mine. Before the 90's, the technology of large single-tooth roller crusher can not strictly control the particle size of crushed products. In order to overcome the uneven strength of the finished product, the body load is large, large maintenance and other shortcomings, designers continue to make improvements to the crusher: in the single tooth roller crusher crushing plate on the lower end of the tension spring; The two ends of the crushing roll of a double - tooth roll crusher are amped with a compressed bullet.
In the 21st century, the coal industry is under the attack of the oil industry and the new energy industry.The traditional coal industry with high investment, high energy consumption and high pollution will be transformed into a new coal industry with high efficiency, low energy consumption, less pollution and investment saving. Therefore, it also puts forward higher requirements for crushing equipment. How to reduce crushing operation energy consumption, reduce crushing noise pollution, waste pollution, in order to achieve energy saving and efficient crushing, is the domestic and foreign coal research institute and tooth roll crusher manufacturers. So the single-toothed roll crusher to double toothed mineral sizers crusher, four-toothed mineral sizers crusher development, various types of strong classifier crusher has also come out. In recent years, these new equipment has been widely used in the domestic coal industry because of its obvious advantages such as simplified process, low consumption and high efficiency, and precise granularity of finished products. However, China's coal reserves have declined greatly after years of large-scale mining, and new requirements for crushing technology and crushing equipment have been put forward for the concern of the coal industry. It is hoped that with the development of China's coal industry, the development of mineral sizers crusher can make greater progress, emerge more crushing methods and crushing equipment.
