Processing Weight: 545T. The ball mill trunnion, also known as the hollow shaft is an important part of the ball mill that carries the rotation of the ball mill barrel. It is a special type of steel casting. It mainly plays the role of supporting and connecting the cylinder in the whole ball mill, and is the entry and exit channel of the material.
The ball mill pinion gear is subjected to more force than the large gear of the ball mill, and its wear rate is also higher than that of the large gear, making it a vulnerable part of the ball structural strength of the ball mill pinion is relatively high, and it is often paired with a quenched and tempered ball mill pinion and a normalized large gear, so that the tooth surface ...
Pinion bearing damage in ball mill Using HD measurement technologies, Bulgarian copper producer Asarel Medet AD monitors the mechanical condition of critical equipment in the openpit mine and flotation plant. This case study deals with the successful detection of outer race damage on a ball mill pinion bearing.
The pinion is a small gear with a matching tooth profile to the ring gear on the ball mill. From a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill.
Pinion speed is indeed 180. Bull gear tooth count is 241. I had a cage failure on one of the pinion bearing 2 years ago, at that time we replaced both bearings. The peakvue trends look good on the bearings. 2XGM is rising and driving my trends up. My Highest readings are in the vertical position on the outboard bearing.

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.
We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
Stanex diaphragm Mill inlet Slide shoe bearing 6 Ball mill for cement grinding Ball mill for cement grinding 7 Optimum grinding efficiency The grinding media are supplied in various sizes to ensure optimum grinding e ciency. In the coarse grinding department, the grinding media are sized to crush just the coarsest particles in the mill feed,
The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill.
Ball mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30' x 41' . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.

Fig. 1 shows that there are four basic components The shell, the heads, the ring gear and the trunnions. The heads are usually bolted to the shell. The trunnions are secured to the heads by bolts or made integrally with the head. The ring gear is usually bolted to one head section. The forces acting on the mill are both static and dynamic.
Ball mill pinion is also called ball mill pinion gear. It is an important component and a vulnerable part of the ball mill transmission system. It forms the ball mill pinion assembly together with the pinion shaft and base structure. AGICO is an experienced ball mill and ball mill spare part manufacturer. We have a strong production capability ...
Ball mill or trunnion bearings are widely used in wind turbine generators, communications satelites, the space shuttle, telpes, bascual bridges, vaccum cleaners, firearms, vehicles, stage lighting instruments, and in many other areas as well. Whatever your need may be, BBR is capable and ready to manufacture to your specifications.
The gear box is a setup intended for making the power transmission from the electric motor to the ball mill. During this stage the gear box plays a crucial role in terms of controlling speed and torque. The gear box is a collection of shafts, bearings, casing and gears in a systematic form to obtain the desired output.

The ball mill pinion bearing is held and we will run mag center, stop the motor and return to mag center and set the coupling gap to manufacture's specifications by axially moving the motor assembly. The coupling, by design will allow around .030" axially movement within the limited end float kit.
As mill size increased above approximately 4,476 kW (6,000 hp), the limits of gear technology were reached and it was no longer possible to drive through a single pinion. Therefore, two pinions were used, each transmitting half of the power to the mill.
The drive of the ball mill consists of an induction electric motor, twostage gearbox and the pinion gear. This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and ...
