Ball mill vs rod mill: what are the differences between the twodevices that are so similar and how to select suitable equipment? please findthe answer in this article.
The structural difference between the two types of ball mill is mainly reflected in the discharge port.
During the grinding process of rod mill, the grinding medium and ore are line contact, thus it has a certain selective grinding effect.The particle size of the product is more uniform with low grinding rate.For coarse grinding, the processing amount of rod mill is greater than the ball mill with the same specification, and vice versa.

Heres my list of ball mills that digital workers should consider for a 3d carving kit.As always, small mills break easily so make sure you have spares of your smallest bits around.
A ball mill is a grinding device that is used to turn material into fine powder.Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals.By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.

The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm.However, the rod mill fine grinding fineness is about 0.833-0.147mm.In terms of the fineness of the ground material, the ball mill has a finer handling ability.
Generally, users can choose ball mill or rod mill on base of their raw materials, product size and properties of the equipments.
what are on earth the factors of influencing the revolving speed of a ball mill?and how to give full play to the role of a ball mill?in fact, no matter which kind ball mill it is, a ball mill, a energy saving ball mill, a large ball mill, or a planet ball mill using in the university laboratory,a cement ball mil using in the cement production, the working principle of them are all basically simalar.So, the factors of affecting the revolving speed of them should have in common as well.The working principle of ball mill is that:the ball mill grind materials at the driving of revolution and autobiography and relying on the friction and collision of the grinding balls in grinding bowl.The higher the revolving speed, the greater the function of the friction and the collision.So when the ball mill works at the formal condition, the discharging grain is basically proportional with the revolving speed of the ball mill.In different mineral industries, the effects of a ball mill"s revolving speed is also different.For example, in coal mine industry, the revolving speed of a ball mill directly impact the movement of the steel ball and cinder-blocks and the grinding process of the coal.If the cylinder body rotate at a very low speed, the coal and the steel ball can"t be brought up,they will stay only in the bottom ,which leads a small rolling mill coal output.On the oppposite, if it rotate at a very high speed, the centrifugal force of the coal and the steel ball is greater than their gravity,the steel ball and coal will rotate together with the cylinder body without the function of grinding the coal.The revolving speed of the ball mill can make the cylinder body steel ball up to a maximum height, at which time the ball mill has the most impact and achieves a best effect of grinding coal.However, in the actual work, the revolving speed of the ball mill is limited by the ratio of transmission device and other external conditions,which make it can"t reach the most suitable height, so it is generally easier to close to.After the explanations above, we know the importance of the revolving speed of a ball mill in the daily work of a ball mill,so in order to improve the grinding efficiency, usually set the revolving speed of the ball mill at a maximum speed.Ball mills are widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
