Selecting a proper mill lining system is always a critical decision for a mining industry. Mill liners shield the shell from erosion by acting as the main power behind grinding. As liners became aged, they lose their ability to grind minerals efficiently. Mill liners need to be replaced on a regular basis as essential maintenance. It is also important to select a renowned liner manufacturer company, from where you would get enough idea about mill lining system and also can purchase a mill liner system as well.
When choosing a mill liner, price is not the only consideration. Selecting a brand-new mill lining system involves several crucial considerations. Mill lining systems’ design configuration and continuing optimization have a significant impact on the successful grinding of material prior to extraction. Several important factors must be considered while choosing a mill lining system. In this article, we will discuss some factors.
Important factors before choosing the best mill liner manufacturer
When choosing a mill liner’s design, many elements must be addressed, including the desired grinding action, mill size, and ore and grinding media parameters, among others. These factors will aid in the selection of the best liner material and geometry.
A lining system can be made of rubber or composite, with cast metal alloy inserts formed into the liners at wear sensitive places, depending on the mill size and material being ground. High energy impacts in large diameter SAG mills, for example, may necessitate the use of abrasion resistant toughened plate inserts. The most important thing is to choose the right lining material for the job.
A proper liner system has two functions- it protects the shell from wear caused by the mill charge’s impact and abrasion, and it elevates and tumbles the mill contents in the proper manner to provide grinding action. To accomplish this, a liner must be made of high-wear-resistant materials and have proper geometry to aid in determining the mill charge’s height and how the material is ground.
Benefit of Rubber and Composite Mill Liner
Grinding mills used to be lined with cast metal linings of various steel or iron alloys, with the lining system chosen based on the level of wear protection and cost. Metal linings have become obsolete as materials technology and design techniques have improved. Today, there are numerous superior alternatives to metal linings.
To prevent mill shells from wear, rubber compounds have been created, and new cast alloys and wear resistant plates can be bonded with rubber to endure high impact abrasiveness.
The impact of a lining systems on mill performance is well understood. Mill lining systems are currently chosen based on a wider range of parameters, including the capacity to achieve mill process performance, wear resistance, convenience of installation, and safety. Furthermore, rather than cost alone, return on investment and total cost of ownership models are essential variables in the decision-making process.
Rubber and composite mill liners are becoming more common, and they offer various advantages over metal mill liners:
Manufacturing ease and speed, as well as shorter lead times
Customizable with the ability to improve abrasion and wear resistance.
When planned and built properly, they outlast metal linings.
The advantages of rubber are combined with the strength of steel in composite constructions.
Installing and replacing is easier and safer. Removing metal liners can be time-consuming, requiring a lot of pounding and gouging with a cutting torch.
To reduce relining times and maximise mill availability, rubber and composite lining systems can be made up of only a few components. When handling heavier components, safety is improved by using rubber and composite liners that are up to 35 percent lighter than metal liners.
Pegging occurs when particles of rock or grinding media become lodged in grate screen apertures, restricting flow. Rubber grate plates are more resistant to pegging than steel grate plates.
They are resistant to particle lock up behind the liners when used in gold applications. To boost liner’s volumetric capacity, lighter mill linings can be optimised. This can improve mill power efficiency and reduce energy waste, resulting in increased throughput and profitability.
Maintenance
When choosing a new mill lining system, your maintenance schedule is a key factor to consider. Reducing maintenance on your mill increases production by reducing mill stoppages. If you choose a suitable material and the right fit, your liner will need less maintenance. You need a liner that will fit into your production schedule.
Conclusion
Consider all aspects of your liner’s design and purpose in order to fully appreciate its value.
By selecting a proper mill liner manufacturer with the right capabilities, including mechanical design, modern simulation tools, advanced materials technology, and a deep understanding of your process requirements, you can ensure your liner is as efficient and productive as possible while decreasing maintenance costs.
The true value of mill linings lies in their total ownership cost and return on investment, and in how a supplier can provide a lining that supports your maintenance schedule, reduces downtime, and lowers per ton production costs.
