At H&G Casting,  we engineer innovative designs, tailored especially for every customer. Our SAG Semi-Autogenous Grinding Mill Liner and AG Autogenous Grinding Mill Liner are manufactured to the highest industry standard for Autogenous Grinding(AG), Semi-Autogenous Grinding(SAG), Primary / Secondary and re-grind rod or ball mills. MGS Casting mill lining system designed by our highly trained, and dedicated team throughout the world has taken your entire comminution circuit into consideration. Supporting our front line Mill Engineers is a large team of extremely specialized design engineers, material chemists, manufacturing and logistics experts responsible for delivering exceptional service.
Optimal mill designs engineered by our team take into consideration service life; grind & power efficiency and ore characteristics, along with costumer circuit constraints both up and downstream of the mill lining.

H&G Casting had success to use ASTM 2074/L2B alloy steel to manufacture AG/SAG mill liners. Under this material, our mill liners span life can be obviously improved. Our Australia customers had ordered more than 10,000 tons per year of this material mill liners.

As a casting foundry, H&G Casting also has own SAG Semi-Autogenous Grinding Mill Liner and AG Autogenous Grinding Mill Liner design. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered. Each of these topics has had a considerable amount of research, and numerous case studies of evolutionary liner design have been published. Based on experience, mill liner designs have moved toward more open shell lifter volumetric capacity and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. Mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1. This ratio range is stated without reference to face angle; At equivalent spacing-to-height ratios, lifters with greater face angle relief will have less packing problems when new but experience higher wear rates than those with a steeper face angle. Pulp lifter design can be a significant consideration for SAG mills, particularly for large mill. All mill sizes increases, the required volumetric capacity of the pulp lifters grows proportionally to mill volume.

Semi-autogenous grinding mill liner also called SAG mill liner, Autogenous grinding mill liner also called AG mill liner. Since the 2014 year, H&G Machinery has had become one of the largest AG/SAG mill liner manufacturers from China. No matter which material you want, manganese steel or Ni-hard steel or Cr-Mo steel or alloy steel; No matter which type of your mill liners need. wave shape or raised edge shape or stepped shape; H&G Machinery is your first choice.

AG SAG Mill Liner Function

Semi-autogenous grinding and autogenous grinding is a powder mill with a large cylinder diameter and a slow rotation. The material is fed into the mill through the hollow journal at the feeding end. Under the interaction of the materials, the material crushed to a certain fineness passes through the discharge The hollow journal at the end is discharged out of the machine. The liner is an important part of the grinding machine.

1. The lifting liner lifts the material to a certain height, the impact of the free fall, and the friction effect between the friction between the materials, so that the materials are crushed and finely ground.
