(PDF) The selection and design of mill liners

The profile can be better customised to suit mill speed and filling and therefore optimise performance, and it allows more material in the lifter for a given base width, but the mill must only run in one direction. 7. High–low double wave ball mill liners – These are a refinement of the wave liner, Figure 5.

Ball Mill Maintenance & Installation Procedure

Mill SHELL Liner & HEAD Liners. Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.

Megaliner™ mill liners

A Megaliner™ element integrates multiple lifter and plate rows and has a minimum number of attachment points. In some cases, the lining consists of up to 80% fewer parts. It covers a large area of up to 8 m² and is light-weight in relation to size. Being several times larger than a traditional lining enables much faster installations.

The Different Types of Mill Liners You Should Know

Grid Liners. All ball mill liners must be very resistant and capable of withstanding high impacts. The milling process uses steel balls to break down the material. The grid liner has the dual role of protecting the cylinder while making the movement of the steel balls effective. Double Wave Liners. People also use double wave liners for ball mills.

Ball Mill Liners

Ball Mill Liner components: Our ball mill liners solutions can be fitted with MultoMet composite lifter bars, shell plates and head plates. The MultoMet range utilises Hardox 500 wear-resistant steel, attached to the leading edges of the lifter bar array and embedded within shell plates and head plates, ensuring maximum abrasion and impact resistance.

SAG Mill Liner Design

Based 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.

Minerals

Most mills can be converted from metal liners to composite rubber liners. These liners combine the best characteristics of metal alloys and rubber to obtain a superior design for use in AG/SAG, grate discharge, overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates

Rubber Ball Mill Liner Wear Rate Estimation

Secondary Grinding Ball Mills experience 1-2 years of liner life, depending on tonnage/ball size. Normally Lifter to Plate ratio is 1:2.Tertiary Grinding Ball Mills experience up to 4 years of liner life. Since, all the mills are unique in their operation and the practical sense in which they run, we do wear measurement during every shutdown.
