what materials are used for linings in ball mills

The lining material is of great importance as there is a significant amount of wear taking place due to the action of the steel balls. The mill consists of a cylindrical drum, sometimes tapered at one end, and usually has a charge of steel balls (up to 40 % by volume) ranging in size up to 125 mm for larger mills.

Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc …

Used in ball mills in the mining industry, the steel form and special hardness of the plates ensures efficient comminution of extremly hard materials. 1. Compact spiral lining. The temporary interruption of a pure rolling motion of the grinding balls by the plow plates improves the comminution effect of medium particle sizes. 2.

In general, wet grinding mills are suitable for rubber linings. The wide operational scope of the company ranges from autogenous mills fed by coarse materials to ball mills employed for very fine grinding processes. Rubber lining can be used for dry grinding as well.

Up to now, nearly half of the lining materials of ball mill in the domestic cement industry are still made of ordinary high manganese steel. The main failure modes of high manganese steel ball mill liners are as follows:

Rubber linings in ball mills are found more efficient than steel linings in respect to capacity, fineness of grind, and power consumption. One test on cement using both a rubber and a steel lined mill showed a 20% greater capacity, 10% less power consumption and 0.9% more material through 200-mesh.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials either wet or dry.

Ball Mill Liner Plate Of Is Used To Protect The Cylinder From The Direct Impact And Friction Of The Grinding Body And Materials. At The Same Time, Different Liner Plates Can Be Used To Adjust The Movement State Of The Grinding Body, So As To Enhance The Grinding Effect Of The Grinding Body On The Materials, Improve The Grinding Efficiency Of ...

Materials as specified above can be used in Ball, Rod, Sag and FAG mills. The mills are Allis Chalmer type, steel heads and usually supplied with white metal bearings, however roller bearings are available on request. Larger mills can be supplied with gear boxes, or direct synchronous motor drive, and variable speed can be an option.

Qiming Casting is Your Foundry for Ball Mill Liners!

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 …

Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.
