This can also lead to bolt breakage through fatigue and ultimately to the liner coming loose from the shell.

A generic wear prediction procedure based on the

A generic procedure to predict the wear evolution of lining surfaces, namely the spatial distribution of wear and the progressive modification of the geometry due to wear, is introduced in the context of shell liners in ball mills. The wear data is accumulated on the surface of the liner by 3D discrete element method (DEM) simulations of the ball

Key considerations when selecting a mill lining system

2020-1-27  A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action. To achieve this, the mill liner profile must be constructed from high wear resistant materials and incorporate

PolyKombo Liners Polycorp

PolyKombo™ Liners. Polycorp PolyKombo™ Liners are a one piece liner with steel lifters and rubber plates designed for use in SAG, AG or Ball mill applications. PolyKombo™ Liners can be manufactured with similar dimensions as existing steel liners to replace

Modification of SAG mill liner shape based on 3-D

2009-5-16  Liners prime duty is to protect mill shell; they also transmit energy to the mill load and lift the grinding media up. Thus, they have a key role in tumbling mills performance (Parks and Kjos, 1996). Mill shell liners have lifters with various profiles resulting in different effects on the grinding mechanism.

Patents Assigned to Minneapolis Electric Steel

Abstract: A new procedure and apparatus for securing shell liners in ball and bar mills. The liners are formed with sockets of special shape at predetermined intervals therealong, and are held within the shell of the mill by bolts having heads, received in the sockets, and threaded shanks passing through the liners and the mill shell to nuts on

[PDF] A structured approach to modelling SAG mill

A numerical framework to predict the three-dimensional evolution of the liner profile within a rotating industrial SAG mill is presented. The need to understand the manner in which the lifter profile develops is emphasised by comparing two discrete element method (DEM) simulations with measured new (i.e. unworn) and worn lifter profiles. The DEM informs the subsequent wear model as to the
