The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight. design and analysis of ball mill inlet chute for roller press circuit in (Unidan Mill S) type FLS Ball mill which are used in the Cement industry for grinding clinker material.

Ball mill trunnion (ball mill hallow shaft) is an important part to load the mill rotary body The neck that connected to bearing liner and the circular that connected to mill shell shouldn't cast with defects, such as, pore and sand hole The neck that connected to bearing liner should have polishing machining and make sure its precision and smoothness So it has strict requirement for casting

Ball Mill Trunnion Liner Ovality Limits. Sep 01 2016 A reverse helix in the discharge trunnion liner retains balls in the mill In a stationary ball mill all ball media rest on the bottom of the mill shell resulting in a higher ball charge level than that in a rotational mill in which part of the ball charge is locked in the active charge and rotated with the mill

Trunnion ball valve have a mechanical means of anchoring the ball at the top and the bottom, this design is the standard design applied on larger and higher pressure valves. Sealing is achieved by spring loaded piston type seats which shut off flow when line pressure acts on the upstream seat.

Ball mill hollow shaft (trunnion) is an important part to load the mill rotary body. it has strict requirement for casting technology. Great Wall Steel Casting is one of the largest casting enterprises in CHINA that are capable of producing high quality ball mill trunnion.

Trunnion Overflow Discharge Ball mill A trunnion overflow mill has an open discharge end. Material flows through the trunnion as a result of the pulp gradient between the feed and discharge openings. A reverse helix in the discharge trunnion liner retains balls in the mill.

A trunnion seal assembly for joining a stationary inlet/outlet box of a ball tube mill to a rotational interior of the ball tube mill includes an outer ring component configured to be mounted to an outer wall of the stationary inlet/outlet box. An inner ring component is joined to the outer ring component substantially concentrically with the outer ring component.

May 15, 2018The ball mill head is the collective name for the end cover of the cylinder and the trunnion. It sustains the rotation load of the entire mill body and grinding media, and continuously operates under the action of alternating stress. It is also the weakest link of the ball mill and the most difficult to control the manufacturing quality.

The best a ball mill can get FL 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. The large alternating stresses placed on ball mill trunnions and heads are a great example. However a trunnion is designed to last for ever,
