What is a Sag Mill?

Date:

Did you know that the mining industry in the United States has grown 11.4% per year? 

If you do not understand your requirements and look at the wrong type of sag mill, then it is likely that you will not be satisfied with your purchase. That is why learning about sag mills is a great starting point when buying new crushing equipment.

Let’s look at what we should know about sag milling, its background, uses, and how it works.

The Different Types of Sag Mills

The different types of mills include full floating, semi-floating, and dry grinding. Every kind of sag mill has its unique benefits and drawbacks.

Full Floating

The full floating feature of the sag mill means that the rocks and stones are not anchored in place but instead float freely in the mill. ‘

This allows for a more efficient grinding process, as the rocks and stones are not held in place and can be easily moved around. The full floating is an essential piece of machinery for many industries and can be used to grind various materials.

Semi-floating

The sag mill is a key component in many mining operations, as it is often used to break up large rocks and stones before they can be further processed.

The “semi-floating” part of the name refers to the fact that the mill is supported on both sides by bearings. This allows the mill to move back and forth and rotate during the grinding process.

Dry Grinding

The dry grinding sag mill grins the ore material to finer particle size. The dry grinding sag mill is typically used for the primary grinding stage of the milling process.

The Working Principle of Sag Mills

The mill is filled with feed material, typically ore particles, which are ground to more acceptable sizes by the action of the mill.

The working principle of sag mills involves the abrasion and impact of the ore particles inside a rotating mill. This results in the attrition of the particles, which reduces their size.

The principle of sag mill operation is similar to that of ball mills, which are also used for grinding materials to more acceptable sizes. If you want to know more, learn about Harcliff Mining Services

Advantages and Disadvantages of Sag Mills

The advantages of sag mills include that they are very efficient at breaking down ore, require less energy to operate, and can handle a wide range of ore. In addition, sag mills are very versatile and can use in various applications. 

One of the disadvantages is the potential for contamination of the mill with tramp material. This can be a problem if you are milling contaminated material and don’t have a way to clean the mill between runs.

Additionally, using sag mills can lead to a higher circulating load, leading to higher power costs.

Understanding the Work of Sag Mill

The Sag mill is an important machine in the mineral processing industry. It is widely used in the comminution process. To get good performance from the sag mill, it is necessary to understand its working principle, advantages, and disadvantages.
