head liners (triangle) This product is an important part for conical ball mill and its call "feed end liners for ball mill' its main function is to protect the end cover of ball mill. The high wear-resistance head liner...
Ball mill ends usually have ribs to lift the charge with the mill rotation. The ribs prevent excessive slipping and increase liner life. They can be made from white cast iron, alloyed with nickel (Ni-hard), other wear-resistant materials, and rubber (Durman, 1988). Trunnion liners are designed for each application and can be conical, plain ...

When the dry ball mill is running, the material is evenly spiraled into the first bin of the mill through the feeding hollow shaft from the feeding device. The bin is equipped with a step liner or a corrugated liner, and is equipped with steel balls of different specifications. The centrifugal force generated by the rota Continue Reading
We have a Russian customer, who has a cement clinker production line, which includes a Ф 2.2m × 6.5m ball mill. One month after the ball mill was put into operation, the mill liners and step liner of the first bin were broken frequently. At most, 18 pieces were broken in one week, which needs to be replaced. It costs a lot.
The spiral on the ball mill liner should be fixed, and the seal and gasket shall be applied carefully, ensuring that there are no leakages. The inner cylinder should be screwed tightly and it should be cemented properly so that it can solidify and culminate the reinstallation process. Step #7: Final check-up

The ball mill is a horizontal cylindrical rotating device, driven by an outer gear, two bins, and a grid type ball mill. The material enters the first chamber of the mill uniformly through the feeding device through the feeding hollow shaft. The chamber has a step liner or a corrugated liner, which contains steel balls of different specifications.
A longer lasting mill liner means less downtime for maintenance or new liner installation. A mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. Safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners.
3.The material is uniformly fed into the first chamber of the mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, and various steel balls are loaded therein. The rotation of the cylinder generates centrifugal force to bring the steel ball to a certain extent. The ...
The ball mill liner is intended to protect the barrel of the ball mill in order to reduce and avoid direct impact and friction of the body and …
In this paper, the milling operation of industrial ball mills using the Discrete Element Method (DEM) is investigated. First, an industrial scale ball mill with a Smooth liner type is simulated. Then, by changing liner type, i.e. Wave, Rib, Ship -lap, Lorain, Osborn, and Step liners, six other independent simulations are performed.
Ball mill liners are the main replacement wear parts for ball mills. These liners are manufactured by wear-resistant material and rubble. As a wear-resistant foundry, Qiming Casting manufactures manganese steel, Cr-Mo alloy steel, and Ni-hard steel liners for all kinds of ball mills, which include: single wave liners, modified single wave ...
Average kinetic energy of grinding body in ball mill with various liners (J) Wave liner Lifter Step liner Double wave liner 0.042557 0.06425 0.02682 0.050798 The double wave liner and the liner with lifters are the most effective because the average kinetic energy of the balls is higher than other type of liners (wave liner and step liner).

Ball mill installation is a must step before it is put into production, which will affect the subsequent use of the ball mill, and even affect the production volume, crushing rate, service life, etc., so the importance of ball mill installation is self-evident.. In addition, the choice of grinding medium is also crucial. In the grinding process, different grinding medium can be …
used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. Obviously, a good liner design and the right operating conditions such as mill speed or balls filling degree, should limit the risk of projection. The purpose of this paper is to further explore the issue
The mill shell liner type, rotation speed and the amount of its loading are the key factors influencing the charge behavior, consequently the comminution mechanism. In this paper, milling operation of industrial ball mills using Discrete Element Method (DEM) is investigated. First, an industrial scale ball mill with a Smooth liner type is simulated.
Liners may he built from MANGANESE STEEL for rod mills and ball mills that use bigger than two inch balls. Or they may be what is known as CHILLED CAST IRON LINERS. This type of liner have their own content formulas and are cast in their own manner as well. An example of such a liner is the NIHARD LINERS.
End liners for ball mills conform to the slope of the mill head and can be made of rubber, alloyed cast steel or wear resistant cast iron. To prevent racing and excessive wear end-liners for ball mills are furnished with integral radial ribs or with replaceable lifters or with both.
