As China's power industry's rapid development, the proportion of the investment and construction in the more than 300 MW capacity thermal power units is increasing. The size of burning coal in the coal-fired boilers requirements of The thermal power units is smaller to fit the burning conditions,so it needs the full grind In the coal-fired thermal power units before into the coal-fired, to the purpose of the stone coal processing, coal in the pyrite, rocks and other debris removal and the fully burning of coal.
So the purpose of my Graduation Design is to design a full grind of coal-fired coal and coal quality and adaptability, power consumption and wear-resistant parts, and other aspects of strength to achieve optimal use of the bowl-mill, Thereby increasing the efficiency of power generation and power plants to get the most cost-effective.
In this paper, it Introducts the structure, working principle of bowl-mill composition and the main components in the design of the necessary theoretical calculations and related strength check, and some structural transformation: The design improves the old series of bowl-mill Roll and increases the Roll wear resistance, reduce the Roll of wear and tear; the design of Roller fliping institution of this bowl-mill has not only a very long service life but also easy maintenance.
