A ball mill is a large cylindrical tube partially filled with steel balls. The ends of the steel cylinder are attached to trunnions that are supported on journal bearings. As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom.


How to repair a crack of trunnion of ball mill,Our company is a large-scale heavy enterprise that taking heavy mining machinery manufactory as main products and integrated with scientific research, production, and marketing.

Trunnions and bearings: The trunnions are made from cast iron or steel and are spigoted and bolted to the end plates, although in small mills they may be integral with the end plates. ... Hence a rod mill generally precedes a ball mill in a grinding circuit especially where a fine size product is required. Ball Mills: -The final stages of ...


Tubular ball mills ride on steel tyres or are supported at 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 synchronous motors that operate through an air clutch or gear system. The girth gear is usually located at one end of the mill but ...


The raw material is fed into the ball mill at the ends, and the steel balls impacting together eventually grind the material into a powder which is collected through slots at the center of the mill. The figure below shows a computer-generated model of a ball mill containing the cylinder, the two trunnions on the ends and the drive gear.


A typical ball tube mill includes a large, cylindrical drum that rotates along its axis, supported by a trunnion on each end. As the drum rotates, a mass of balls and coal or other material mix in...


Ball mill trunnions and heads are subject to large alternating stresses during operation. Even though trunnions are designed for infinite life,there is always a risk of cracks developing due to small casting defects, wear of the inner surface of the trunnion or …

Trunnions built from 2011 (when scales were introduced) to September 2016 use a scale that requires 12VDC power; Trunnions built from October 2016 to mid-January 2017 require 5VDC power. Trunnions built after mid-January 2017 work with either 5VDC or 12VDC power. These can be identified by the gray connector on the scale cable.


The trunnions are the protrusions from the side of the barrel that rest on the carriage. A trunnion (from Old French " trognon ", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development.
