This customer is from a construction company in Bamako, Mali. According to our customer's high demand of production capacity and granularity of finished production, our engineer assembled 2 mobile crushing stations of FTM1142E710 model and FTM3S186PYF13 mDetails
Working Principle Operation The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where theDetails
Generally the driven mill sheave is of split hub construction to facilitate field assembly Vbelt drives allow use of higher speed motors generally low in initial cost Motor speeds should be between 580 and 1160 rpm The lower speeds apply to large diameter mills the higher speeds to the smaller DIRECT CONNECTED Ball Mill DRIVEDetails
The dynamic analysis of ball mill foundation is a typical problem of soilstructure interaction and the substructure method is used to estimate the structural vibrationDetails
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 in that way it transfers the motion from the drive to the shell see Figure 1 taken from 1 Figure 1 Mechanical system of a ball millDetails
Grinding in Ball Mills Modeling and Process Control Article PDF Available in Cybernetics and Information Technologies 122 · January 2012 with 4857 Reads How we measure readsDetails
The inertia for this mill reflected to the motor shaft is calculated to be 24300 ftlbs2 The time to accelerate the mill to the design needs to be included in the analysis of mill motor drive systems These drives typically have an for some of the gear trains used on ball mills DRIVEDetails
Pinion shafts made of 18CrNiMo76 material are used for transmitting torque from motor to gear box used in bowl mills of fossil fuel fired power plants This work elucidates the metallurgical investigation that was carried out on a failed pinion shaft for analyzing the cause for failureDetails
This is a ball mill in Gold Processing The gearboxes for both drives are shaft mounted to the pinion shaft with an attached torsion arm So the gearbox moves a bit during operation and would be a contributing factor to vibration by designDetails
As an example the calculation of the input shaft of bevel straighttoothed gear included in a ball mill drive using software was made As the result of shaft analysis its static strength fatigue strength and flexural rigidity in the form of numerical values were calculated and the graphs of distribution of equivalent stress changes inDetails
