Application of ball mill and Raymond mill in limestone milling

Limestone is an important raw material used in construction, highway, railway construction, etc. Depending on the user's production technology, the processing technology of limestone is also different, and of course the choice of equipment will be different.Take the ball mill and Raymond mill for example. Although both equipment can be used for the grinding and milling of limestone, there are differences between the two in terms of working principle, scope of use, and even in terms of production. Which grinding equipment would we choose is better?How about the price?

First. Application area

1. Ball mills are mainly used to grind gold ore, iron ore, copper ore, bauxite and other metal minerals. It can be seen that ball mills are mainly used in mineral processing, refractory materials, cement construction, glass ceramics and other fields.

2. Raymond mill is suitable for high-precision milling of more than 200 kinds of materials in mineral, chemical, construction and other industries with non-flammable, explosive and non-metallic materials with a Mohs hardness of not greater than 9.3 and a humidity of less than 6%.

Second. the grinding method

1. There are many types of ball mills, which can be divided into two grinding forms: dry grinding and wet grinding.Wet ball mills grind materials with water or materials containing a certain amount of water. Dry ball mills do not allow materials to be ground with water.

2. Raymond mill is a vertical grinding equipment, which requires a dry environment when working, so it can only be used for dry grinding operations.

Third. Discharge particle size

The feed particle size of the ball mill is ≤20-≤25mm, the discharge particle size is 0.074-0.89mm (about 20-200 mesh), and the output is 0.65-615t/h according to the user's specific production situation.

The feed particle size of Raymond mill is ≤30mm, and the production fineness is 80-325 mesh (0.044-0.173mm). Some materials can be ground to 800 mesh. According to the grinding fineness of different materials, Raymond mill's production capacity ranges from 8-176t/shift.

Fourth. Working principle

1. During the operation of the ball mill, it mainly relies on the impact grinding and peeling of the steel ball and the material in the grinding medium to achieve the crushing of the material.

2. During Raymond grinding operations, the grinding rollers and grinding rings roll and crush the materials under the action of centrifugal force when the equipment rotates to achieve the purpose of crushing the materials.
