Q1: Why is limestone grinding important in steel manufacturing?

In steel plants, finely ground limestone is mainly used for desulfurization, fluxing, and slag conditioning. Stable particle size and consistent chemical properties help improve steel quality and reduce production costs.

Q2: What limestone fineness is commonly required in steel plants?

For most steel manufacturing applications, limestone powder in the range of 200–325 mesh is sufficient. Some desulfurization processes may require finer powder, depending on system design and reaction efficiency.

Q3: Which type of grinding mill is suitable for limestone in steel plants?

Raymond mills and vertical roller mills are widely used. Raymond mills are suitable for medium capacity and stable operation, while vertical mills offer higher efficiency, lower energy consumption, and are ideal for large-scale steel plants.

Q4: How does raw material hardness affect mill selection?

Limestone is a medium-soft mineral, which makes it suitable for most grinding technologies. However, moisture content, feed size, and impurity levels should be considered to ensure smooth operation and reduce wear.

Q5: What factors matter most for efficiency in Thailand?

In Thailand, energy cost, environmental regulations, and equipment durability under high temperature and humidity are key. Choosing a mill with low power consumption, good dust control, and corrosion-resistant components is essential.

Q6: How to ensure long-term stable operation?

A reliable grinding mill should feature easy maintenance, readily available spare parts, and strong technical support. Proper system design and operator training also play a critical role.

Q7: What capacity should be considered?

Steel plants usually require continuous and stable output. Selecting a mill that matches current demand while allowing room for future expansion ensures better long-term efficiency.
