The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
Ball Mill Equipment Plans Ball mill - Wikipedia The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates,, AM King offers full selection of high quality ball mills including top brand name manufacturers Kobe-Allis and Denver at AM King .
The motor was driven at a fixed speed of 2000 r/min, which caused the maximum sliding velocity at tip of 5.3 m/s and 2.5 m/s for the pinion and wheel, respectively. The lubrication system was carried out by using jet-lubrication with GL-5 heavy-duty extreme pressure gear oil (85w/90) as a lubricant, which is shown in Table 4 .

9620. For some closely spaced work, an endmill-style cutter would make life easier, if slower than a standard gear cutter. Like a tight gear cluster, or working close to the indexing fixture. That said, cutting tool life would be much lower and more difficult/expensive to resharp. 03-28-2016, 07:02 PM #11.
Ball Mill PINION SHAFT BEARINGS. Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.

Hi All I have a gearbox with increasing amplitude of the output shaft 100t GMF and running speed sidebands. the gearbox is driving a pinion gear for a ball mill. attached is a pic of a very similar mill with crudely annotated details. the circular waveform suggest eccentric gear? anyone got some thoughts on what I'm looking at. Also note the pinion has 20t and the 5th harmonic …
Once your Ball Mill Pinion Equipment is repaired we then do a six hour test run for overheating, vibration, and leaking to ensure our 24 Month Guarantee. National Gear Box Repair can do all of these repairs and rebuilds at a considerable amount …
1.The wear of the pinion surface should not exceed 30% of the tooth thickness. The wear of the tooth surface of the ball mill is not more than 25% of the tooth thickness. It can be used on the reverse side and should be scrapped when it is 1/2. 2.The deformation of the rim of the large gear of the ball mill should not exceed 7.5mm.
Pinion Shaft is the key component in the transmission system of the mill, especially the large-scale SAG mill, AG mill and ball mill. It has strict requirements for material and manufacturing, complex process flow and high precision. Therefore, the selection, technology and manufacture of pinion shaft reflect a certain industrial level.
The big diameter ball mills have the inching driving device for easy starting and convenient maintenance. The air forced grease spaying atomizer ensures the perfect lubrication of the pinion and girth gear. Application Scope The overflow ball mill can be used for primary grinding or re-grinding for the expected particle size.
CPM Gearboxes and pellet mills offer a different line of products for industrial solutions. Like the CL Series pellet mill which is a low cost solution to pelle mills aiming to process 30 to 2000 pounds per hour. It has a built in hopper with a vibratory feeder and speed controller allowing the discharge f pellets through the front.

Fig. 5 illustrates the pinion temperature distribution of a gear set having optimum alignment. The temperature gradient. which is the temperature at Position 1 minus the temperature at Position 5, is zero indicating that the load int,ensity is the same on both ends of th pinion. Position 1 is taken toward the mill end of the pinion face.

Reply with quote. #1. I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth.
The mill is estimated to be capable of drawing the 5500 kW at the pinion at 75% of critical speed with a 12 to 15% or greater ball charge and a total charge of 28%. The mill should be able to operate at the design conditions (10% ball charge, 28% total charge) in the speed range of 50% to 75% of critical speed over the full wear life of the liners.
