US20170304836A1 Lifter bar, method for making a lifter

The lifter bar comprises a lifter bar body having an outer surface conforming the outer surface of the lifter bar, and a fixing element for connecting the lifter bar to the shell of the grinding mill. The lifter bar body further comprises a first portion and a second portion forming a continuous lifter bar body. The fixing element is embedded

How Ball Mills Lifter Bar Affects Charge Motion

Aug 08, 2018 It is important to study the motion of en masse grinding media for different profiles of the lifter bars. Lifter-bar shape changes after weeks of milling causing a change in the ball trajectories; these changes in turn affect the power draw. The performance of a ball mill is known to be affected by the design of the liners.

Grinding Mill Liners Mineral Processing & Metallurgy

Aug 06, 2015 The metallurgy of the lifter bars must be carefully matched to the grinding application. In mills with high impact such as large SAG mills, a high impact resistant Cr-Mo steel is required. In applications of low impact, the more abrasion resistant, castings such as Nihard are utilized to achieve maximum life through high abrasion resistance.

Suggested rubber shell liners & lifter bar thickness

Anyway, I will guess this is a 2-2.5 meter diameter mill. Without knowing anything else, start with this: Use around 110 mm center to center for lifter bars. Do not go crazy adding too much lift/height to your bars in hopes of increasing wear life. It will kill capacity. Good luck in your rubber ball mill

How a Grate Discharge Ball Mill Works

Aug 13, 2015 How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out and discharged.

US8235318B2 Mill liner for a grinding mill Google Patents

A mill liner element is structured with an elongated elastomer member having a non-elastomeric backing plate and a plurality of non-elastomeric inserts formed into the elastomer member to provide a liner element that provides a lifter bar element and a wear element that is less prone to cracking compared to conventional all-metal mill lining elements, and which provides ease of handling and

Royston also noted new grates can slow milling rates: some mills change every second grate at relines, while others use alternating high and low grate-lifter bars, to maintain milling performance. The backflow of non-discharged rocks can limit the pulp-lifting performance and add to wear at the base of the pulp lifters.
