Grinding Mill Trunnion End

Product Details

Grinding Mill trunnion end refers to a kind of hollow structure of the shaft, is the key component connecting the transmission part of the mill and the rotating part, its main role is to support and rotate the grinding cylinder, which is used frequently in the mill. It is usually made of cast steel or forged steel and has high hardness and strength after high temperature quenching and tempering treatment.

Grinding Mill trunnion end is the main transmission part of the mill, which usually consists of shaft liner, shaft sleeve, hollow shaft body, bearing and other accessories. Among them, the shaft liner is made of high-strength materials such as high-chromium cast iron, and its main role is to protect the shaft from damage and prevent premature fracture of the shaft. The bushing is the part in contact with the shaft, and its inner surface usually adopts a progressive tapered design to reduce the wear of the shaft. The hollow shaft body is the main part of the hollow shaft, and its shape is mostly cylindrical or conical, and its diameter and length are determined according to the specifications of different ball mills. The bearings are the supporting and friction-reducing parts, which usually adopt paired angular contact ball bearings or roller bearings.

Grinding Mill trunnion end structure design is a complex and critical one. In the design of Grinding Mill trunnion end, it is necessary to comprehensively consider a number of factors such as strength, rigidity, loss, bearings, etc. to ensure its working efficiency and stability. A more concise design can greatly improve the working efficiency and service life of the mill, and provide better equipment protection and support for subsequent mining production.

1. ZMI provide the custom products that according the custom designing or drawing. It includes the heavy casting, forgings fabrication products, and final machined products.

2.Durability

Our mill hollow shafts are made of strong steel. For large mill hollow shafts, in order to ensure the strength and stability of the shafts, ZMI usually adopts composite structure, that is to say, the inner hollow part is filled with high-strength materials, such as steel bars, steel plates, etc., to increase the strength and rigidity of the shafts. This enables our products to operate in harsh processing environments and extends their service life.

3.Strict quality inspection

Our products undergo rigorous quality testing before leaving the factory, including chemical, mechanical and microstructure testing by an independent laboratory, NDT tests including UT, RT, MT and PT,and German GS-1000 direct-reading spectrograph.

4.Proven manufacturing processes

We have our own factory and production plant. Mill hollow shafts require different raw materials and sizes to handle different materials or for different types of mill applications, and our mature and complete production line allows us to customize our products according to our customers' needs.
