where to measure ball mill liner thickness

Ball Mill Liner Thickness Measurement Tools Minimum thickness for rubber liner in ball mill Hello We measured the thickness of sheet plate and lifter bar rubber liner in a ball mil for a gold mine to estimate when we have to change them

Wave height above the liners from 15 to 2 times the liner thickness Rubber liners of the integral molded design follow the cast metal design If using the replaceable lifter bar design in either metal or rubber the number of lifters should be about 33 π D in meters for D in feet divide 33 π D by 33

Hello We measured the thickness of sheet plate and lifter bar rubber liner in a ball mil for a gold mine to estimate when we have to change them What is the minimum thickness of sheet plate to preserve the drum of the ball mil And what is the minimum thickness of lifting profil of the lifter ba

Over 7 million thickness points and hundreds of crosssections critical path components and hot spots detected from every scan Proven and trusted solution Outotec MillMapper is the only patented and specialized mill liner measuring technology Used more than 4000 times worldwide – the equivalent of scanning a single mill for over 500 years

Here is a homemade tool to measure or obtain a fingerprint of your SAG and Ball Mill Liner wear patternprofile Each time you shut down get a profile and build a wearlife over time database to better predict your next reline job or monitor improvements to your liner design

Measurement of the liner wear in the mill of an ore dressing plant is one of the critical parameters in the context of mill downtime and production performance The total downtime cost during measurement can be reduced by a significant fraction by using appropriate measurement devices

Figure 5 High–low wave ball mill liner Materials The selection of the material of construction is a function of the application abrasivity of ore size of mill corrosion environment size of balls mill speed etc liner design and material of construction are integral and cannot be chosen in isolation

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

These are also known as a KICKER BAR LINERS The important measurements being the WIDTH of the valleys the HEIGHT of the lifting portion of the liner and the overall THICKNESS of the liner A liner takes up space and will reduce the tonnage accordingly

Learning curve start with very low ball charge and build up over time Do not let the mill charge run down Soft oxide ore low charge high risk of liner damage can be catastrophic First set of liners should take ore into account conservative design Low feed rates only with low ball charges use mill trajectory modelling

Ball mill liner One of the most common types of grinding machines used today in many industries is a ball mill This device works by using mass media balls made of solid materials embedded in a compartment or container in such a way that the material is crushed and powdered at the time of the cavity of the compartment on the material

Our ball mill liners solutions can be fitted with MultoMet composite lifter bars shell plates and head plates The manganese steel and alloy 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

Mar 13 2017 · Our Ball Mill Liner can be fitted with composite lifter bars head plate shell plate grate plates pulp lifters trunnion and bell mouth liners and others can ensure maximum impact resistance and abrasion The thickness of shell plate can be changed this help to balance mill capacity and extend Mill Lining service life Lifter bars supply series materials and sizes it improved milling operation efficiency

The results show that in the overflow mill when the height difference between the peak and the wave valley of the cylinder liner reaches about 60of the maximum grinding ball diameter the ball movement intensity in the mill is moderate and the mill is in the best working state

liners to obtain liner shape ball size distribution liner volume and liner mass suite d for load cell calibration and ballore charge volume information Th e survey protocol is given in Table 1

Mill liners developed by Multotec include Ball Mill Liners SAG Mill Liners AG Mill Liners as well as Scrubber Liners Focusing on good fitment of liners in which Multotec are experts results in reduced installation downtime which in turn facilitates increased production

83 Centrifugal force outward Fc mp 2 Dm 2 81 is the angular velocity mp is the mass of any particle media or charge in the mill and Dm is the diameter of the mill inside the liners Gravitational force Fg mpg 82 The particle will remain against the wall if these two forces are in balance ie

In a stirred media mill the mill body is static and the charge motion is created by an agitator such as a rotating spiral or impeller We provide both original body liners and spiralimpeller liners designed as a system for each of the mill sizes of Metso’s extensive range of stirred media mills

production of mill liner bolts for the mining and cement industries to exact specifications thus ensuring the most cost effective bolts in the industry Through the company’s manufacturing expertise production capabilities and understanding of its customers’ requirements Lister Bolt delivers premier products and

Ball Mills Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s The basic construction of a ball mill is a cylindrical container with journals at its axis

As with wearresistant steel ball lining board is also important vulnerable parts of ball mill ball mill plate due to the impact of the steel ball and material and grinding exfoliation coupled with the corrosion of the pulp while the damage plus the mineral lining and steel ball material hardness and installation operation condition the influence of various factors such as is common
