Various Cement Production Lines Developed for Customers

Leading Cement Production Line Supplier

It is mainly divided into 3 stages of raw material preparation, clinker calcination and cement grinding It is commonly known as "2 miling and 1 burn". If the preparation of pulverized coal is included, it can be renamed as “3 miling and 1 burn”. 

Cement production can be divided into dry method (including semi-dry method) and wet method (including semi-wet method) according to different preparation methods of raw materials. Today's cement production mainly uses the new dry process cement production method. This production mode is mainly reflected in the preheating of the high temperature of the preheater and the high temperature of the exhaust gas before the raw material is put into the kiln. The calcium carbonate in the raw material is in the decomposition furnace. Nearly 90% of them are decomposed into calcium oxide. 

Investment income

Gaw material grinding power consumption of the total electricity consumption by 30%, coal mill power consumption 3%, cement grinding power consumption accounted for 40%, a reasonable choice of grinding equipment is of great significance to ensure product quality and reduce energy consumption . 

Cement final grinding program recommended:

Conclusion: Vertical grinding has become the mainstream equipment for cement production. Compared with the other two schemes, the annual energy consumption can save more than 7 million, once and for all.

Cement Production Process Overview

Cement Production Process and Equipment

AGICO Cement Equipment Advantages

  1. Providing EPC general contracting/turnkey service 
    Since the establishment, AGICO has been engaged in research and development and innovation of large-scale cement kiln grinding equipment, and has formed a complete design and development, product manufacturing, marketing, equipment installation and after-sales service. The production management system provides the general contracting and turnkey engineering services for the design, manufacture, installation, commissioning and production of cement production lines for many customers at home and abroad. 
  2. Grinding equipment, original spare parts independent research and development production 
    Whether it is raw material grinding or clinker grinding, whether it is rotary kiln or ball mill, AGICO can be manufactured according to customer needs, product safety and reliability, intelligent, environmental protection High, it is used in many cement plants across the country. 
    It is worth mentioning that AGICO has its own large-scale spare parts processing base, so it can provide any parts, electric control cabinets, oil stations, etc. on the mainframe, which completely solves the trouble for customers to go around and purchase matching equipment. The customer realizes “choosing the Great Wall and producing no worries”. 
  3. The cement production line has large production capacity and high degree of automation. It adopts the current domestic advanced distributed control system (DCS) to improve the automation level of the entire cement production line, achieve high-quality operation of the unit, and provide stability guarantee for the production of high-quality cement. 
  4. Advanced technology, power consumption is 20%-30% lower than ball milling combined process. 
    The production line adopts new dry process cement preparation process, which can reduce electricity consumption by 20%~30%, greatly reduce production cost and improve the comprehensive benefits of enterprises.
