Lubrication System of the Ball Mill. Ball mill is the eccential equipmet in ore dressing industry, which is improtant for fine grinding of the materials. However, the main parts of it shall replace regularly due to the engagement of each works well if the main bearing and the pinion bearing oil in regularity.
Low and high speed reducer shafts are connected by flexible couplings. This arrangement of girth ring and single pinion drive is preferable for larger mills of up to 4000 HP. At present (1984) Krupp Polysius AG has four ball mills with single pinion drive under construction. Each of these mills has a drive power of 3500 kW (4700 HPJ
Ball Mill Maintenance Procedure Guide . Regular ball mill maintenance is an important factor to ensure the normal and stable operation of the ball mill. In the process of application, only if the ball mill maintenance process is carried out correctly, the ball mill can operate normally and the production efficiency can be improved.
The PACE of the bull gear and the face of the pinion gear will use one of three main tooth patterns, a SQUARE CUT tooth, a DIAGONAL CUT and one with a HERRING BONE pattern. To protect these surfaces it will be part of the operator's duty to be sure that the proper grease is being applied on the correct schedule.

The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor, gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives. Gear mesh frequency is present at 1x to 3x and similar amplitudes on both sides.
"The pinion drives the trunnion; it's what makes the ball mill turn. 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. ... Whether that is in ...
Adding more coal to the process changes the load of the mill but the ball charge stays constant. The amount of ball charge in the mill is a function of the condition of the mill liners. The mill drive system consists of the main mill motor, the main reduction gear box, mill pinion and girth gear.
AG Autogenous Grinding. The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media; the rock itself. In conventional milling, the ore is crushed to, plus or minus, 3/8 of an inch, before it is put into a mill for grinding. In a autogenous mill the ore is fed directly into ...
Wet ball mill pinion installation method is to wet ball mill pinion bearing and fixed on the basis of being winched to the center line, align with the oblique axis of . ball mill installation Although there are many types of ball mill, the method and sequence of ball mill .
Installation of Ball Mill Pinion 1. Before installing the pinion, carefully check the bearing pedestal, bearing cover, rolling bearing, pinion, shaft, and other parts, remove the burrs on the gear surface, and thoroughly clean them before installation. 2.
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.
The installation of a ball mill requires careful attention to detail, and once the installation is complete, there are several important tasks that need to be performed before the mill can be put into operation.
The order of starting procedure is to start the lubricating pump of the mill first, ball mill will be started only when the oil pressure reaches kg/cm², next start the spiral classifier, when they run normally can start to feed the ball mill.
Solution: replace the pinion of the ball mill, add two anchor bolts on the inner side of the pinion and the meshing side of the big gear, and reinforce the base again. After the operation, the ...
SAG mill and two 26 ft ball mills, all made by Metso. The drive systems that enable the mills to operate at benchmark levels of reliability, efficiency and availability were made by ABB, whose solution comprises a MW gearless mill drive (GMD) for the SAG mill, and two 13 MW lowspeed dualpinion ringgeared mill drive (RMD) systems for the ...
Install the retainer ring and splash ring as shown. BALL MILL ... A plate steel gear guard is furnished with the mill for safety in operation and to protect the gear and pinion from dirt or grit. As soon as the gear and pinion have been cleaned and coated with the proper lubricant, the gear guard should be assembled and set on its foundation. ...
"The pinion drives the trunnion; it's what makes the ball mill turn. 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. ... Whether that is in ...
als industry. The grinding mills can be equipped with ring gear pinion drives as well as with the COMBIFLEX® drive. The standardisation allows for short delivery times and minimisation of spare part inventory. If required, ring motor drives can be fitted to shellsupported grinding mills up to the largest sizes. SAG/ball mill circuit ...
representative of a German mill supplier representative. Ball mill speed can be reduced during short maintenance measures, inspections of the SAG mill. This avoids fixed speed pinion drives have to be stopped with a prior grindingout / drainout process before interruption and the necessary time to restart. As a consequence, variable
Online pinion temperature monitoring of the pinion with infrared temperature sensors is the most consistent and effective means of detecting misalignment of gear driven mill systems, allowing the user to quickly detect and correct any misalignment that may develop.. A common failure cause of gear driven mill systems is misalignment, which in its most severe form can cause rapid tooth fatigue ...
Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing. Small and batch grinding mills, with a diameter of 700 mm and more, are available. These mills are of a special design and described on special request by all Ball Mill Manufacturers.
Monitoring pinion temperatures on mill gear pinions is an effective and efficient means of monitoring alignment and operating condition. Pinion temperature measurement when applied properly can adequately predict multiple failure modes, including misalignment, overheating from a loss of lubricant event, overheating from improper lubricant, and ...

A ball mill is a crucial piece of machinery used in grinding and mixing materials in various industries. It works by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. Ball mills are used extensively in the mining, construction, chemical, and pharmaceutical ...
• The mill may have inherent issues such as: o Misalignment o Deflection and bending of teeth o Torsional twisting and bending of the pinion shaft • These issues can cause an uneven load distribution, creating adverse effects on the gear set life. • Higher quality levels of gears and pinions will ensure
