Considering the materials which are used to make rod mills, we usually adjust the diameter of the grinding rod at 75 …

In the wire rod mills, it is normal to use rolls with grooves. Common groove sequences in the intermediate mills are 'square oval' and 'false round (round) oval'. It is also widespread to use 'diamond-square', diamond-diamond, and 'box groove' sequences upstream in the roughing mill. There are other types of the pass designs also.

General Information/Equipment Design. Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher, also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device.

Although they have the similar working principle, there are many differences between ball mill and rod mill on details. 1. Configuration of ball mill and rod mill. The proportion of cylinder shape is different. The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller ...

crushers, rotor or disc mills. Moist materials tend to block the ring and bottom sieves which can lead to a blockage of the machine. As a conse-quence, material is lost and much time and effort has to be spent on cleaning the mill. There are a few exceptions: colloidal grindings can only be carried out in ball mills by adding a liquid. Fresh ...
