Shell liners Shell liner and charge interaction. Shell lifter design is critical to good mill performance. The important process objectives in SAG mill shell lifter design are: • to provide the key between the mill charge and the mill shell for charge motion, • to maximize the rate of delivery of thrown grinding
DetailsMill linings, Weir Rubber Engineering, Salt Lake City, UT 84126, United States of America . ABSTRACT . Dramatic shortcomings of mill liner designs, especially of large SAG mills, - such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable
DetailsSpecial Features SAG Shell Liners : The material of SAG mill liners are low C or high C Cr-Mo Alloy steel,which depends on the specific working condition of the SAG mill. The hardness of AS2074 L2B is HB310-HB380. We can make big size SAG mill liner castings with Sodium Silicate Sand Process & Resin Sand Process.
DetailsThe initial set of SAG mill shell liners were a 78 row, 12 degree face angle high/low design with a difference between the high and low lifter of 95mm. The high/low lifter spacing led to packing ...
DetailsBased on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
DetailsTo a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and …

DetailsSAG mill liner manufacturer – H&G. SAG mills also known as Semi-Autogenous Grinding Mills are actually grinding mills that come shell diameter to length ratio of about 2 most commonly. Due to their higher aspect ratio, these mills are capable of generating both cascading and thrown ball milling actions along with shell lining.

DetailsBall 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.
DetailsIt transforms the mill rotation into charge motion and both profile and spacing must be carefully selected to suit each specific mill. When designing a shell lining, Outotec considers the type of grinding, mill size and speed, maintenance schedules, safety, impact levels, efficient use of materials, and many other parameters.

Details> Mill trajectory modelling based on bar heights, angles, spacing and speed is very predictive > Field trials are the acid test - operator, designer and vendor > Optimisation strategy: – Maximise impact grinding AG/SAG mills – Avoid impact on the shell rather the toe of the charge – Maximise liner life by protecting with mill lifters
DetailsFailure analysis of the old SAG mill shell liners. Since the commissioning of φ 9.15 × 5.03 semi-autogenous mill in Baima concentrator, the operation rate is only about 55% due to the irregular damage and replacement of mill liners, which seriously affects the economic benefits. The main failure mode of the shell liner is shown in Fig. 1 (a).
