Manufacturing industry directly reflects the level of a country's productivity and it is an important factor to differ developing and developed countries. The manufacturing occupies an important share of the national economy of the developed countries, and the mining machinery industry also occupies temporarily indispensable location in the manufacturing sector. The professional mining machinery manufactures should commit to the exploration and study of the milling equipment and make their own contribution to the development of the manufacturing.

Manufacturing is the main sector of industry. Raymond ball mill high-end equipment is an important foundation of the development of manufacturing, and also a concentrated reflection of the development of national manufacturing levels. At present, the driving force and the environment of China's industrial development are undergoing profound changes, and Chinese industry has entered a critical period when only speeding up transformation and upgrading can promote development.
China's industrial transformation and upgrading should be in accordance with essential requirements of going the new road to industrialization with Chinese characteristics and building a modern industrial system, taking scientific development as the theme, accelerating development transformation as the main line, and independent innovation and reform and opening up as a driving force, promote the deep integration of informatization and industrialization, foster the growth of strategic new emerging industries, transform and upgrade traditional industries and accelerate the development of producer services, fully optimize the technical architecture, organizational structure, layout structure and industrial structure, establish the industrial development on the basis of innovation-driven, intensive and highly efficient, environmentally friendly, benefit the livelihood and endogenous growth, and continually enhance the industry's core competitiveness and sustainable development capacity to lay a more solid foundation for the industrial power construction and building a moderately prosperous society.
Ball mill is mainly made up of cylindrical shell, end cover, bearing, and big ring gear and so on. We can load some steel balls or steel rods, whose diameter is from 25mm to 150mm,the intake quality is about the 25～50％ of the effective volume of the shell. There are end covers on both ends of the shell, to be connected by bolt and flange at shell end. There are holes at the center of end covers, called hallow shaft necks propped up to bearings, therefore, shell can turn. Main gear ring is fixed on shell. In driving unit, main gear ring and shell are driven to turn by motor, shaft coupling, reducer and pinion. When shell turning, grinding medium rise to a certain height along the shell wall and drop in form of parabola or in torrents.
Material is fed into shell from hallow shaft neck of input end, and transfer gradually towards output end. During the movement of material, steel balls will be lift to a certain height by the rotating shell to crush the material by fall. Part of steel balls will grind the material by dropping in torrents in shell. Whole movement procedure of material is the procedure of crushing.
