Before casting, our professional engineers first optimized the technical structure of trunnion, according to running characteristics of ball mill.
Aug 18, 2015 Trunnion Bearings of Ball Mill are the important parts loading mill cylinder rotary. These casting surfaces such as the neck contacted with the mill spherical tile and the circular arc neck contacted with cylinder are free of blowhole and sand inclusion in the cast process the position parts contacted with spherical tile need to grinding after machining in machining process.
The trunnion is the main ponent in the ball mill equipment which is both the inlet channel and the end cover of the ball mill and carries the rotation of the cylinder Continuous operation under alternating stress the wear is relatively large especially the trunnion at the inlet and outlet ends is
Trunnion Variations. Several variations and modifications of the Trunnion Magnet system are available for any specific application. The size of the blind trommel and magnetic circuit can be varied to retrofit an existing ball mill and available space at the discharge.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
In the drawings FIG. 1 illustrates a preferred embodiment of the invention providing reducing and pulverizing mill 10 of the ball or tube mill type. Mill 10 includes a hollow shell 12 mounted for rotation about a horizontally disposed, longitudinal axis by means of opposed trunnion
Sep 19, 2016 Trunnion bearing and Slide Shoe bearing are two main classifications of Ball Mill bearing, and while making a choice between these two, you should refer to these following points 1. If a person is looking for a higher load machine where the surface area is restricted, Trunnion
Bearings - smaller ball mills use anti-friction cylindrical roller bearings. Larger ball mills use trunnion bearings. How Ball Mills Work. The below video is an extract from our Mechanical and Electrical Engineering Explained Online Video Course.
The best a ball mill can get FLSmidth has installed almost 4000 ball mills at locations worldwide which has given us a unique insight into the stresses and strains arising out of ball mill operations.
