Vertical Mill VS Ball Mill For Pulverized Coal Preparation System

According to the partition of parameters such as feed size, discharge size, fineness of finished products, moisture content of materials and properties of materials, enterprises need to select the type of grinder according to actual production needs. Should vertical mill or ball mill be used in pulverized coal preparation system?

1: What are the advantages of vertical mill and ball mill in processing pulverized coal?

Answer: The particle size, uniformity and water content of pulverized coal have a direct impact on the application of downstream industries. The higher the fineness of pulverized coal processing, the higher the value of coal utilization. Therefore, the comparison of pulverized coal vertical mill and ball mill can proceed from the four angles of output, fineness, cost and environmental protection.

2: What is the production process of vertical mill system for pulverized coal preparation?

Answer: The main advantage of using vertical mill system for pulverized coal processing equipment is mainly reflected in the high production efficiency of vertical mill for raw material grinding. Vertical mill uses grate cooler to deal with waste gas efficiently and minimizes the impact on the surrounding environment. In addition, the stable control of the fineness of the material by the dynamic separator in the vertical mill structure ensures the output and quality of the finished pulverized coal. Pulverized coal vertical mill is a closed free grinding system. If the automation level of customer equipment is required, PLC/DCS automatic control system can be added to strengthen the remote control of vertical mill operation.

3: What effect does the comprehensive utilization of vertical and ball milling of pulverized coal have on the grinding process?

Answer: Generally speaking, a single vertical mill can process pulverized coal. The vertical mill can realize the functions of crushing, grinding and grading. The grinding particle size of ball mill is also very standard. It is more suitable for small-scale concentrating production line. Compared with the output of 60 tons per hour of vertical mill, the production efficiency of ball mill is low.
