Ball mill or ball mills are steel or ceramic cylinders that are similar to cylinders and usually cover a non-metallic ceramic coating around it to prevent metal contamination. The wing rods are mounted horizontally and partially filled with round steel or ceramic balls to turn hard materials into soft powder.
Ball mill or ball mills are cylinders made of steel or ceramic that are similar to cylinders and usually cover a non-metallic ceramic coating around it to prevent metal contamination. The wing rods are mounted horizontally and partially filled with round steel or ceramic balls to turn hard materials into soft powder.
In these mills, the pellets rotate very rapidly around a horizontal axis, turning non-metallic materials, including chemicals, minerals, paints, and ceramics, into powder. The working method of the ball mill is such that during the rotation of the wing of the shaft, the cascading movement of the bullets leads to actions such as hitting, abrasion and breaking the material. What happens in a ball mill is that one end of the material is added to the ball mill and the powder from the material comes out of the other end. An example of the design of the wing rod and the bullets inside it and their rotation can be seen in the figure below.
There are a number of variables to control and consider when to use the wing mill. Among these variables:
Ball or pebble variables:
Mill base charge:
Adhesion or change over time
Rotation speed is very important in a ball mill and there are three basic operating modes for it that show the cascading motion of the balls inside the ball mill.
Three operating modes occur in a ball mill, including:
Waterfall or Cascading
When a mill spins rapidly, the material inside the mill shaft or ball mill pushes the material out of the mill shaft by centrifugal force. Under these conditions, no erosion occurs for the wing shaft, and reducing the rotational speed in the ball mill creates something like a cataractous operation that will be very inefficient. This leads to excessive erosion of the material, which causes the material to become too dispersed.
The wing is filled to 3 to 7 times the weight of the bullet powder, which effectively grinds mineral and ceramic stones. The material to be removed from the ball mill must be pulverized enough to fill the cavities between the balls. Bullets move inside the wing of the mill, hitting large particles of material by hitting each other in the same direction and bringing them to the breaking point.
In general, wing mill can be used to produce dry or wet products and is able to produce the product on a micronized scale.
Wing mills are very useful equipment for grinding and crushing. Ball mills can be offered to customers in different types according to the facilities they offer. The types of wing shafts are listed below.
Industrial Mill Wing
This type of ball mill is larger than other wings of ball mills.
They can be the size of a refrigerator or a bus.
The main difference with other types is the number of their rooms.
The air system is mandatory in this type.
The horizontal type is the most common type used in industry.
Some horizontal ball mills are equipped with timers to examine the material at different time periods.
You can see the processed materials in it.
These types are often used for laboratory work.
These types are suitable for small applications and are used in laboratory fields.
In this type of ball mills, balls in different sizes and for different applications are used.
