Rod mills are an essential part of many industries, including mining, construction, and agriculture. They are used to grind materials into finer particles, which can be further processed or used for a wide range of applications. With the use of long cylindrical rods, these machines can efficiently grind materials to the desired size, making ...

2. Grinding medium. Rod mill commonly uses steel rods with diameter of 50-100mm as grinding medium, while ball mill uses steel balls as grinding medium, and the difference of grinding medium is the main difference between them. The steel balls of ball mill are in point contact with each other, while the steel rods of rod mill are in line ...

The high-speed wire rod refers to the wire rod rolled by the "high-speed non-twist rolling mill". The rolling speed is 20-60 m/s, and each weight (disc) is 0.4-0.6 tons (generally three of six heads are seen on the market). In the rolling process, the performance of the product can only be ensured by air cooling on the cooling line.

This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications.

The cumulative adjustment of the roll gap of the first and last rolling mills of the wire rod mill should not exceed 0.3mm. The main reasons for the stacking steel in the tail during rolling are as follows: (1) The size of the rolled product in the previous pass is too large, so that when the rolled product enters the next pass, it is squeezed ...
