The application of the four-tooth Roll Crusher enables the circulating fluidized bed unit to adopt primary crushing, thus saving equipment and construction costs for the second stage crushing in power plants. Therefore, the four-tooth roll crusher has become the preferred crushing equipment for low-cost and low-cost circulating fluidized bed units. Due to the particularity of circulating fluidized bed boilers, the selection of crushing system has a particularly high requirement for the particle size of coal entering the furnace, which is not more than 10mm. This is the main parameter index that crushing equipment needs to achieve, so it is required that the crushing equipment has a small particle size, wear resistance, anti- blocking, and easy maintenance. Usually, the crushing system is divided into two types: secondary and primary crushing. 1.1 In order to meet the requirements of crushing particle size, the secondary crushing system is commonly used for the selection of crushing equipment in China. The first stage is a coarse coal crusher, which crushes coal blocks not exceeding 300 mm to less than or equal to 50 mm; The second level is a fine coal crusher, which crushes 50 mm coal blocks to below 10 mm.
