Briefly explain the difference between Raymond mill and ball mill

Raymond mill and ball mill are also used as grinding equipment, but in fact there are many differences between them, the most significant difference is that the powder ground out of Raymond mill is much finer than that of ball mill. What are the specific differences between the two?

First of all, Raymond mill and ball mill belong to the same mill or powder mill, but their grinding fineness difference is relatively large, Raymond mill is much finer than the ball mill. The discharge speed of ball mill is fast, and the particle size of the crushed material is relatively coarse, and the size of the grinding product is 0.3~0.2mm or -0.074mm, and the mass fraction of the particle size is 45%~65%.

Raymond mill powder machine, on the other hand, belongs to the ultra-fine grinding equipment, and the fineness of grinding of mineral raw materials can reach below 2μm. Conventional mills cannot meet these requirements. The outstanding advantages of Raymond mill are: stable performance, easy operation, good reduction of energy, wide adjustment range of product size, thus it is used to finely grind some non-metals below medium hardness. The feed size of Raymond mill is generally 15-20mm, and the size of the grinding product is usually 0.044-0.125mm. Raymond mill is mainly used for ultra-fine grinding processing of various ores, construction materials and chemical materials with Mohs hardness below 9.3 and humidity less than 6%, such as graphite, talc, kaolinite, limestone, etc. The fineness of the finished product is up to 2000 mesh. The fineness is up to 2000 mesh, which is more suitable for projects and projects with high requirements for fineness of some materials.

The ball mill is mainly used for materials with Mohs hardness below 7 and humidity below 6%, which is widely used in ferrous and non-ferrous metal processing, fertilizer processing, refractory material processing and silica manufacturing, etc. It can grind the materials in dry and wet mode, and the fineness of the finished products can reach up to 425 mesh, which is generally used in the mineral processing line for the grinding and processing of materials to prepare for the next process of the production line.

There are many kinds of mining equipment, each type of equipment is divided into many different kinds of equipment, such as grinding equipment includes ball mill, rod mill, Raymond mill, ultra-fine mill, three ring medium speed micro powder mill, high pressure micro powder mill, high strength mill and other equipment, each kind of equipment corresponds to different needs.

OCP hopes that users can find the most suitable equipment for themselves. If you have any demand for mining equipment, we are always waiting for your consultation, and our customer service is online 24 hours a day.
