Description

[0001] The present invention relates to a ball mill with improved configuration comprising a liner,

The present invention relates to a ball mill with improved structure including a liner, and more particularly to a ball mill having a structure including a liner having a structure in which a driving force is transmitted to rotate the main body, The present invention relates to an improved ball mill.

A variety of methods have been proposed for processing large particles or materials into finer particles, and in the industry, these machines are generally classified as mills.

The pulverizer is roughly classified into a roughing machine, an intermediate pulverizer, a pulverizer, and a pulverizer depending on the size of a solid particle to be processed, but a pulverizer having a narrow meaning is often contained in a pulverizer. Therefore, it has been widely practiced to classify the pulverizer in a broad sense into two types, a pulverizer and a narrower pulverizer. Also, according to the operating conditions, it is divided into a dry mill, a wet mill, or a batch or continuous type. The power given to the crusher is applied to the powder through the crushing medium to perform the crushing action. In this case, compression, bending, layering, impact, friction and the like are considered. It is considered that some of them act in combination in the actual crusher.

Examples of the crusher include a jaw crusher, a hammer mill, a corn mill, a rod mill, a ball mill, and a jet mill. Among them, a kind of mill called a ball mill is a ball made of steel in a rotating cylinder, which is rotated together with the material, and the material is crushed by the impact caused by the ball movement. The balls used here are various depending on the raw materials such as cast iron, cast iron, flint stone, and natural stone. The length of the tube is a standard type that does not exceed the diameter, but there are types such as a tube mill having a diameter longer than several times the diameter, and a compound mill having a middle portion thereof. The inner surface of the cylinder is embedded with a liner having a material such as special steel or nickel plate, and the built-in liner is worn and worn out due to friction with a steel ball, etc., and must be replaced. Further, since a large amount of noise is generated by colliding with a plurality of spherical steel balls and a material or a liner, a buffer member including rubber or the like is inserted between the liner and the outer cylinder.

However, in the prior art, such a cushioning member is coupled to the outer tube in a plurality of pieces by using a bolt or the like, so that the cushioning member coupled to the bolt is worn out due to wear of the bolt or the like, The gap is developed and fine particles penetrate into the gap, and the wear of the rubber can be promoted more quickly and the noise may be generated. Also, when the rubber is replaced, it takes about 2 ~ 3 months .

It is further preferable to reduce the power for rotating the main body that houses the ball mill.
