Before purchasing a ball mill, we need to understand the model, output, structure, etc. of the ball mill. Before putting the ball mill into production, we need to understand how to load the ball and the medium ratio. During use, we need to consider how to increase output and how to solve problems such as ball mill swelling. Where are all these questions going to find answers? Today, the editor summarized common problems related to ball mills and shared them with everyone.
1. What are the types and significant features of grinding machines?
Answer: According to the different media of the mill, it can be divided into: if the media is steel balls, it is called a ball mill; A medium made of steel rods is called a rod mill; Those whose medium is gravel are called gravel mills; A machine that uses its own ore as a medium is called an autogenous mill. Adding an appropriate amount of steel balls to the autogenous mill forms a so-called semi-automatic mill.
According to the shape of the casing and the discharge method, ball mills are further divided into short cylindrical, tubular, and conical overflow discharge and grid discharge. Rod mills are further divided into cylindrical overflow discharge and open low-level discharge. Self or semi-automatic mills are mainly short cylindrical.
2. What is the representation of mill specifications?
Answer: The representation method is: diameter x length, represented by a symbol as D x L. For example, if a 2700 x 2100mm ball mill is used, its diameter is 2700mm and its length is 2100mm.
3. What are the types and characteristics of ball mills?
Answer: There are two commonly used ball mills in the selection plant: grid type and overflow type. The only difference between them is that the overflow type does not have a fan-shaped grid plate device in the ore discharge part. The slurry of the overflow type ball mill is automatically discharged through the ore discharge port, while the grid type has a forced ore discharge function due to the installation of grid plates, thereby increasing the processing capacity and reducing ore over crushing.
