Brief Introduction to the Design

Cement is a basic material of the national economy, is used widely and largely, is known as "the food for construction industry". As an important cement cementing material, is the world's most widely used, up to the amount of building materials .cement is the main part of the building materials industry. Cement is widely used in civil construction, water conservancy, national defense and other projects. Cement is one of the three basic materials construction industry, can be widely used in civil, industrial, agriculture, water transportation and military projects. Cement industry is basic raw material industry of economic development, production and construction, people's living indispensable. Cement industry is heavy industry, is one of the socialist modernization indispensable industry.

As China's economic development, the cement industry has reached a considerable scale. In the 21st century, China's cement industry breakthrough occurred changes, new technology, new equipment intensive production replacing the backward scattered small production, dry cement and industrial technology development has attracted worldwide attention from one side bring out the fast development of China's economic construction and social progress. "Twelve Five" plan is a critical period of building a moderately prosperous society, the economy will maintain steady and rapid growth, the cement industry is facing opportunities for development: industrialization, urbanization and new rural construction to further stimulate domestic demand, affordable housing projects and high-speed rail infrastructure, rail transportation, water conservancy, agriculture and rural driving, such as cement demand continues to grow. Thus, Cement market has good prospects in the future of China.

China's cement industry is currently in a critical period of technology and product structure adjustment, the cement production process to achieve large-scale, automated, high-quality, high efficiency, low consumption, environmental protection standards. This design choice 5000 t / day clinker cement plant raw material preparation plant process design, the purpose is more profound familiarity vertical mill works, in order to fully understand the vertical mill appeared in the work process problems, and solutions to problems and ultimately achieve savings of energy consumption of cement grinding process, so cement
