At The Same Time, Different Forms Of Linings Can Be Used To Adjust The Moving State Of The Grinding Body To Enhance The Grinding Effect Of The Grinding Body On The Material, Which Is Helpful To Improve The Grinding Efficiency Of The Mill, Increase The Output And Reduce The Metal Consumption. Ball Mill Rubber Linings Metal Materials In China Have Been Gradually Replaced By High Wear Resistant Rubber Linings, But With The Continuous Application Of Wear Resistant Rubber Linings In Ball Mill Linings, Metal Linings Have Been Gradually Replaced As The Mainstream Of Market Development. In Addition To Protecting The Cylinder, The Cylinder Rubber Liner Also Has An Effect On The Movement Law Of The Grinding Body. In Order To Meet The Requirements Of Various Working States (Crushing Or Fine Grinding), The Material Of The Shape Of The Rubber Liner Is Also Different. When The Grinding Is The Main, The Lining Should Have a Strong Pushing Ability To The Grinding Body, And At The Same Time, The Lining Should Have Good Impact Resistance. When The Grinding Is The Main, The Protruding Of The Rubber Liner Is Relatively Small, The Pushing Effect On The Grinding Body Is Weak, The Impact Is Small, And The Grinding Effect Is Strong. The Rubber Liner Is Required To Have Good Wear Resistance. Mill Rubber Lining Characteristics 1. High Wear Resistance And Impact Resistance The Rubber Liner With High Wear Resistance And Corrosion Resistance Is Cured By Scientific And Reasonable Formula, Which Makes The Liner Have Good Physical And Chemical Properties, Hardness Between 60 Shore a And 65 Shore a, Impact Toughness Value More Than 25 Joules, Service Life Is More Than 2 Times That Of Polyurethane. Able To Withstand Huge Shocks. In The Work Can Maintain The Surface Shape Of The Liner For a Long Time To Ensure The Mill Stability To Increase The Output By More Than 5%. 2. High Strength And Toughness In The Process Of Using Rubber Liner, Special Rubber With Good Thermal Stability Is Used To Make The Product Achieve High Strength, High Hardness And High Toughness To Meet The Process Requirements Of Wear Resistance. 3. High Cost Performance And Adaptability After Advanced Special Rubber Vulcanization Process Treatment, It Has The Characteristics Of High Hardness And High Toughness Value, Which Makes The Rubber Liner Have Good Wear Resistance. Compared With Polyurethane Liner, The Wear Resistant Rubber Mill Liner Shows Excellent Performance And Price Ratio. Can Adapt To Mine Wet Grinding, Dry Grinding, Mixed Grinding And So On. Ball Mill Rubber Parts Quality As Far As The Wear Property Of Mill Liner Is Concerned, There Are Many Similarities Between Rubber Liner And Polyurethane Liner, But There Are Also Basic Differences. The Main Difference Between Rubber Liner And Polyurethane Liner, In Addition To The Unique Elasticity Of Rubber, Is That It Is Used To Make Wet Mill Liner, Which Is Not Affected By The Corrosion And Wear Of Slurry, And Different Rubber Varieties And Properties Can Obtain Rubber Liner With Different Wear Resistance, Elasticity, Impact Resistance And Chemical Corrosion Resistance To Withstand The Impact And Grinding Of Grinding Medium And Mineral Materials During Grinding. Therefore, Using Rubber To Make Wet Mill Liner, We Should Make Full Use Of This Favorable Characteristic Of Rubber Elasticity, In Order To Achieve The Cushioning Effect Of Liner And Reduce Wear. Using Unique Wet Formula Design, Combined With Nanocomposite Dispersion Technology, We Can Obtain Wet Nano-Rubber With Excellent Performance, Which Has Excellent Wear Resistance, Strength And Elasticity, And Greatly Increases Its Service Life. Experiments Show That When The Impact Speed Is Small, The Liner Has Only Elastic Deformation; When The Impact Speed Is More Than 9 m / s, The Liner Has Surface Damage. Of Course, The Cushioning Effect Of The Rubber Liner Is Also Related To The Impact Angle. When The Impact Angle Is 90, The Cushioning Effect Is The Largest And The Wear Of The Liner Is The Smallest. With The Decrease Of The Impact Angle, The Wear Of The Liner Gradually Increases. Mill Rubber Liner Installation Requirements 1. When The Rubber Liner Is Installed, The Back End Liner And The End Cover Of The Cylinder Shall Be Filled With Cement Mortar Mpa a Compressive Strength Grade 43.5. The Bolts Of The Rubber Liner At The Fixed End Shall Not Be Filled With Cement Mortar And Shall Be Capable Of Turning Or Entering Or Leaving. Rubber Linings Are Usually Directional, So You Must Pay Attention When Installing Them. 4. All Places Where The Arc Length Of The Circumferential Crevice Can Not Exceed 310 Mm, Are Wedged With Steel Plates To Separate Them. The Gap Between Adjacent Linings Is Not Greater Than 3~9 Mm.. 6. a Spacer Shall Be Laid Between The Liner And The Inner Surface Of The Cylinder According To The Design Requirements. If There Is No Requirement, The Compressive Strength Grade 42.5 Mpa Cement Mortar May Be Filled Between The Liner And The Cylinder, As Far As Possible, And The Excess Part Shall Be Squeezed Out By a Strong Liner Bolt, And The Liner Bolt Shall Be Fastened Again After Solidification Of The Cement Mortar. 7. When a Liner With a Rubber Pad Is Installed, The Rolled Rubber Plate Is Opened Three ~ Four Weeks Before Installation To Allow It To Be Freely Elongated; In The Use Of The Rubber Plate, The Long Side Of The Secondary Rubber Plate Follows The Axial Direction Of The Cylinder And The Short Side Follows The Circumferential Direction Of The Cylinder. 8. To Carefully Check The Rubber Liner Bolt Holes And Liner Bolt Geometry, Carefully Clean The Liner Bolt Holes And Liner Bolt On The Flash, Burr, Protruding, So That The Bolt Can Freely Penetrate Into The Required Position. 9. The Complete Set Of Rubber Liner Bolts Shall Consist Of Piercing Bolts, Dust-Proof Washers, Flat Washers, Spring Washers And Nuts; To Prevent Ash Leakage, The Use Of Dust-Proof Pads Shall Not Be Forgotten. 10. Torque Wrenches Shall Be Used To Tighten The Linings And Bolts Of Different Specifications Shall Be Tightened In Accordance With The Corresponding Tightening Torque Requirements.

ball mill liner design

There are many different designs and styles of ball mill liners. As with grinding balls local economics and ultimately operating costs determine the best design and material to use. The initial set of liners is rarely the final design selected. Based upon individual experience, mill superintendents develop preferences for liner designs. The following is given as a guideline for the initial set of liners.

For 60 mm (2.5) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately 13.1 D in meters (for D in feet, divide 13.1 D by 3.3). Wave height above the liners from1.5 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 3.3 D in meters (for D in feet* divide 3.3 D by 3.3) with the lifter height above the liners about twice the liner thickness. The use of double wave liners, particularly when using 50 mm (2) or larger balls, may show a loss of 5% or so in the mill power draw until the waves wear in and the balls cannest between the lifters.

When liners, and double wave liners in particular, wear with circumferential grooves, slipping of the charge is indicated, and this warns of accelerated wear. When the top size ball is smaller than 50mm (2.5) and mill speed is less than 72% of critical wear resistant cast irons can be used. For other conditions alloyed cast steel is recommended.Rubber liners are well suited to this same area and not onlyreduce operating costs but can reduce noise levels.

Single wave liners are recommended for larger size balls (50mm/2.5 and larger). The number of the lifters to the circle equals approximately 6.6 D in meters (for D in feet, divide 6.6 D by 3.3). The liners are from 50 to 65 mm thick (2 to 2.5) with the waves from 60 to 75 mm (2.5 to 3) above the liners. The replaceable lifter bar design madeof either metal or rubber in about the same design proportions can be used. There could be a loss in power with rubber particularly if the mill speed is faster than about 72% of critical speed, and the ball size is larger than 75 mm. Because of the impacting from the large balls, single wave liners for ball mills are usually made from alloyed steels or special wear-resistant alloyed cast irons. Because of the difficulty of balancing growth and wear with work hardening manganese steel is used infrequently and then with extreme care to allow for growth.

When a grate discharge is used the grates and wear platesare normally perpendicular to the mill axis while the discharge pans conform to the slope of the mill head. The grates and wear plates are normally made from alloy wear resistant cast steel or rubber. They are ribbed to prevent racing and excessive wear. The dischargers and pans are generally made from either wear resistant cast ironor rubber, or wear resistant fabricated steel.Slot plugging can be a problem in grate discharge mills. Whether the grates are made of metal or rubber the slots should have ample relief tapered toward the discharge side. Total angles 7 to 10 degrees (3.5 to 5 degrees per side) are commonly used. Metal grates often havea small lead-in pocket or recess which can fill in with peened metal rather than have the slot peen shut. With the proper combination of metal internals and rubber surfaces, rubber grates have flexibility that tend to make them self cleaning and yet not fail due to flexing.

Except when using rubber liners, the mill surfaces are covered with a protective rubber or plastic material toprotect the surfaces from pulp racing and corrosion. This is done in wet grinding mills. Since dry grinding mills get hot due to heat from grinding generally rubber liners and rubber materials cannot be used.

Shell liners may be furnished of various materials and of several designs. In each case the material used is the best obtainable, resulting in the lowest cost per ton of ore ground. The liner contours are selected for the specific grinding application and take into consideration liner wear, scrap loss, and mill capacity.

Liners cast of Manganese Steel, Ni-Hard, Chrome-moly, or other similar materials may be of the step type, block type, wave type, or the two-piece plate and lifter construction. These are illustrated on the right. During the past years of building ball Mills various other shapes of liners have been tried, such as the pocket type, spiral liners, etc.; in most cases it is found that these special shapes and designs are not justifiable from the standpoint of economics. They involve additional costs which are not generally recovered from an increased efficiency in milling operation.

Lorain Shell Liners consist of high carbon rolled steel plates accurately formed to the mill shell radius. These are held in place by rolled alloy steel heat treated lift bars. This type liner is carefully engineered for the specific grinding application. Variations in lift bar design and liner plate thickness provide this flexibility of design for application.

All shell liners designed for ball mill operations are of such size and shape that they will easily pass through the manhole opening to facilitate relining operations. In rod mill work the design is such that they will easily pass through the large ball open end discharge trunnion.

Where cast liners are used, and especially in rod mill applications, we furnish rubber shell liner backing to help cushion the impact effect of the media within the mill and prevent pulp racing. With the Lorain type of liner such shell liner backing is not required. For special applications where severe corrosive conditions exist a shell liner of special alloys can be furnished and also the interior surface of the shell can be treated to protect such parts from the corrosive conditions.

Head liners are of the segmental type constructed of Manganese Steel, Chrome molybdenum, or Ni-Hard and are designed to pass easily through the manhole opening or discharge opening in the case of rod mills. For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner itself.

Where cast liners are used shell liner bolts and head liner bolts are made of forged steel with an oval head to prevent turning and loosening within the liners. These are held in place with two hex nuts and a cut washer. For wet grinding applications special waterproof washers can be furnished.

Theeffect of liner design upon mill performance appears to have received little attention. Clearly, the main function of the liner is to form a removable surface to the null body, which may be replaced when seriously worn.

It is also clear however, that the metal plates which serve this purpose may have a surface which ranges from smooth in one which carries an intricate pattern of raised bars or sunken depressions. The merits of the various types do not appear, however, to have been studied.

where smooth liners are those which have projections insufficient to give appreciable keying between the liner and the ball charge, whilst lifter liners are those which are so heavily ribbed as to give rise to appreciable interlocking between the balls and the liners.

Various common types of liners are illustrated in Fig. 6.12. Although these liners have various patterns of projections, or depressions, to give an amount of interaction between the liner and the grinding medium, it would be expected that wear would round the edges. It is doubtful whether, after some time in service, the performance of a mill with these liners differs appreciably from that of a mill with a smooth surface. Liners furnished with heavy lifter bars are also sometimes used and in such a case the locking of the ball charge to the shell must be very effective. Nevertheless, although a few vague general statements to the effect that a lifter mill gives a product with different size characteristics to that of a smooth mill have appeared, the point does not appear to have been widely investigated. It is probable, however, that, on the grounds of differences in the size characteristics of the products, there exists no sound reason for the use of lifters in preference to the normal smooth liners.

It is possible that, when a material with a low coefficient of friction is milled, the charge might slip on a smooth mill shell, with consequent loss of grinding capacity, and in such a case the use of lifter bars might well be the solution. It has also been suggested by one of the authors, Rose, that the use of lifter bars might eliminate the surging of the charge sometimes encountered in mill operation.

An entirely different conception of the duty of the mill liner underlies the design of the studded liner developed by Usines Emile Henricot of Count St. Etienne. These liners, illustrated in Fig. 6.12 and Fig. 6.13, consist of comparatively thin plate liners with uniformly spaced studs on the working surface; these studs being integral with the plate. Provided the spaces between the studs are not allowed to become choked with tramp-iron, etc., the studs furnish a good key between the shell and the charge which, it is claimed, leads to a greater power consumption and to improved grinding. Furthermore it would appear that the studs impose a definite geometrical arrangement in the outer layer of balls which, in turn, brings about a closer packing, throughout the ball mass, than obtains with conventional types of liner. This effect would also lead to improved performance. Evidence of this effect of the studs upon the packing of the charge appears in Fig. 6.13b, for the balls are clearly seen to lie in rows in the mill instead of in completely random array.

An incidental merit claimed for these liners is that the high bearing pressure between the balls and the studs of the liners leads to work hardening of the studs; with a consequential reduction of the rate of metal wear.

The Henricot liners, which have been discussed in a paper by Belwinkel, appear to be the only attempt so far made to influence the grinding characteristics of a mill by means of correctly designed liners. It would therefore appear that there is some room for development in this direction.

The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners material and shape are different which base on requirements. When the grinding media contacts with different shape of ball mill liners, the movement state will also change, thus enhancing the crushing effect on the material. This design of the mill liners effectively improves the grinding efficiency of the ball mill machine, increases production, and reduces metal consumption.

The grinding mill liners are the main wearing part of the ball mill equipment. The ball mill liner replacement should in time when the lining plate is excessively worn. Therefore, the selection and design of mill liners have always been of great concern to users.

As one of professional ball mill liners manufacturers, we summarize the main functions of the three-point ball mill liners. It mainly involves the protection of the barrel and the control of the grinding medium.

The mill liner is installed inside the ball mill barrel, separating the grinding media from the barrel, effectively buffering the direct impact of the grinding media on the barrel. Therefore, the barrel is protected, and the service life of the barrel and the entire ball mill equipment is prolonged. The ball mill liners are embedded with the barrel, and at the same time, the rigidity of the barrel is enhanced.

Due to the special shape of the grinding mill liner surface, the grinding media contacts the grinding mill liners, and the huge friction force drives the steel ball upward. The steel ball is lifted to a certain height and dropped, while impacting and grinding materials.

Angle spiral grinding mill liner and cone classification liner have automatic classification function, which can make grinding media of different quality in the cylinder carry out reasonable forward classification along the axial direction of the mill and the change of material size. The automatic grading ball mill liners enable the larger steel balls in the barrel to be concentrated at the feed end to crush larger materials, while the smaller steel balls are concentrated at the discharge end to crush smaller materials.

Different ball mill equipment is suitable for different grinding materials, and the type of grinding mill liners selected will also be different. For example, is the rod mill liners the same as the sag mill liner design? Which type of cement mill liner should be used to grind cement in order to reduce the frequency of ball mill liner replacement as much as possible?

According to the material classification, the common ball mill liners mainly include high manganese steel mill liners, alloy steel mill liners, rubber mill liners, ceramic mill liners and magnetic mill liners.

The mainstream ball mill liners materials currently used in the market are alloy steel and rubber. Alloy steel mill liner is wear-resistant and impact-resistant. Alloy steel has good physical and chemical properties due to its alloy properties, and its service life is more than twice that of high-manganese steel. The ball mill rubber liner has a high wear resistance index, high rebound rate, and high abrasion resistance and tear strength. It also has the advantage of reducing noise.

According to different grinding requirements, ball mill liners are roughly divided into 9 types, which are wedge-shaped, corrugated, flat-convex, flat, stepped, elongated, rudder-shaped, K-shaped ball mill rubber liner and B-shaped ball mill rubber liner. These 9 kinds of grinding mill liners can be classified into two categories: smooth grinding mill liner and unsmooth grinding mill liner.

The smooth grinding mill liner has a large sliding property, has a strong grinding effect, and is suitable for fine grinding processes. The friction of the unsmoothed grinding mill liner is large, which can improve the material and steel ball very well, and has strong agitation effect, so it is more suitable for rough grinding process.

As a ball mills supplier with 22 years of experience in the grinding industry, we can provide customers with types of ball mill, vertical mill, rod mill and AG/SAG mill for grinding in a variety of industries and materials.
