Iron ore is an important raw material for iron and steel enterprises. In order to extract iron with high yield, it is necessary to carry out crushing, grinding, and other pre-treatment work. The crushing equipment adopts coarse crushing type iron ore jaw crusher and fine crushing jaw crusher to crush iron ore into a particle size suitable for grinding and enter the grinding stage. There are two types of commonly used powder grinding equipment: ball mill and Raymond mill. So which one is more suitable for grinding iron ore?

Application field and processing effect
Ball mill is a commonly used powder grinder machine in ore dressing. It mainly grinds all kinds of ores and other materials, which is widely used in mineral processing, building materials, and the chemical industries. The particle size of discharge is 0.074-0.89mm.
Raymond mill is one of the indispensable equipment for grinding and processing non-metallic ores. It is widely used in dolomite, limestone, kaolin, cement, gypsum, glass, and other non-flammable and explosive high-fine powder processing with Mohs hardness not greater than 9.3 and humidity below 6%. The particle size of the finished product can be adjusted in the range of 80-325 mesh, and some materials can reach 600 mesh.

Ball mill is more suitable for iron ore grinding
1. In terms of discharge particle size,  the output size of the Raymond mill is finer than that of the ball mill, which can be directly applied in powder industry, while the ball mill only grinds the material into small particles. Combined with the grinding requirements of iron ore, it is not necessary to have a high-fine particle size finished product, but to facilitate the next extraction process, so it is more appropriate to use a ball mill.
2. The ball mill is more suitable for the kinds of materials. Iron ore belongs to metal ore and is also an important mineral processing material. Ball mill is inclined to mineral processing, while Raymond mill is inclined to non-metallic ore powder, so ball mill is more suitable and has better effect.
3. From the economic benefits of the whole iron ore dressing process, the ball mill is more suitable and more effective. Although the discharge powder size of ball mill is not as fine as Raymond mill, it can meet the requirements of the next extraction step. In addition, Raymond mill needs more grinding time and power than ball mill, and the output is not as large as ball mill, which leads to the increase of production cost of users, so it is uneconomical and cost-effective.
It can be seen from the above that choosing a ball mill to grind iron ore is more suitable and the effect is better. Nile machinery produces a variety of powder milling equipment, with many categories and complete model, and the output can meet the user's standard. Therefore, users can choose the appropriate equipment to grind iron ore according to the actual situation.
