The new PulpMax™ mill liners are designed to increase the throughput of semi-autogenous (SAG) mills and substantially boost the wear life of liners, the company said.

At an open pit polymetallic mine in Mexico, there were problems afoot in the two 38 ft diameter SAG mills. At the heart of things: the design of the steel discharger linings. Adopted to reduce the number of lining pieces and thus shorten installation time, the design was having some unintended – and serious – consequences.

Rotary ball mill is composed of feeding part, discharging part, turning part, transmission part (reducer, small transmission gear, motor, electric control) and other main parts. The hollow shaft of the rotary ball mill is made of cast steel, and the lining can be removed and replaced. The large rotary gear is processed by casting hobbing, and the cylinder body is equipped with a wear-resistant ...

recognized as delivering 1.5 – 4 times the wearlife of steel liners. 2. Reduced Weight Lowers Costs: Rubber liners are 75 to 80% lighter than steel liners, increasing energy efficiency of the mill by 15%. Less stress on the mill for reduced maintenance. 3. Leakproof: Rubber liners are perfectly sealed to eliminate opportunity for

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

A small steel charge addition to an AG mill can boost throughput, result in more stable operations, typically at the consequence of a coarser grind and higher operating costs. An AG circuit is often designed to accommodate a degree of steel media for circuit flexibility. ... SAG Mill Liner Design. ... A. Mill Charge. Charge Weight/Volume ...

Figure 2: Cascading-impact action in a SAG mill. Rubber and composite mill lining systems. In the past, grinding mills were typically lined with cast metal linings of varying steel or iron alloys, and lining system selection was typically driven by level of wear protection and cost.

And, of course, the other big advantage is that rubber-lined mills make less noise than ones with steel liners," he said. Practice Trends Affect Liner Requirements E&MJ asked one of Australia's experts in SAG-mill liner technology, Dr. David Royston, about recent trends in SAG milling practice and how this has affected the design of liners.

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...

A line drawing of the Fort Knox SAG mill liner configuration and spare liners awaiting installation. Five and one quarter inch steel grinding balls - cannon balls - occupy 8% of the mill volume and are consumed in the grinding action at the rate of 600,000 pounds per month.

The mill lining can include only rubber liners or be a combination of steel top and rubber liners to give the best performance value. Advantages. Thickness of rubber can be modified according to specific mill and process values; Excellent wear resistance; Easy installation with dedicated fixing system; Light weight vs. full steel liner

Ball Mill / SAG Mill Steel Shell Liners. Unicast Shell Liners are cast in materials ranging from chrome-moly steels to high chrome white iron. A minimum hardness of 450 to over 650 BHN ensures maximum strength and a significantly longer wear life. We offer Shell Liners in single, multi-lift and classifying styles for efficient grinding performance.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
