Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills ... power consumption at mill shaft with this charge as 4110 kW. ... mill. The results of sieve analysis are depicted as below: Size Reduction Progress I Chamber II Chamber 0 10 20 30 40 50 60 70 80 90 100
Nov 12, 2013· ball mill power . dear experts. we have a ball mill in combi mode for cement grinding . roller press before the ball mill. the supplier has given 28% grinding media filling, with shaft power 2270 kw only. ball mill size is *11 m. grinding media size is max 30mm . it is a monochamber mill designed to grind the roller press product.
analysis. However, they generate significant stresses which may lead to failure of couplings or worse, shafts themselves. It is therefore necessary to implement other measurement techniques. For the vibratory expertise of a ball mill which presents, once a year, a breakdown of the intermediate shaft
Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal C3 is the correction factor for mill diameter and is given as; 𝐶𝐶3 = 𝐷𝐷 (3) However, it is important to note that C3 = vessel used in producing the ball mill was got from a
Apr 01, 2021· The ball mill machine is wide accustomed method cement, salt product, building material, refractory material, fertilizer, ceramics, and glass, etc. The ball mill, also known as the rod mill, will work in a dry manner or wet way. you choose the operating way of a little ball mill machine according to your material and discharging way.
The dynamic analysis of ball mill foundation is a typical problem of soilstructure interaction, ... The height of mill shaft is m above ground. The weight of mill and charge (ore and ...
CASE STUDY: Failure Analysis of a Gear Shaft. This month's case study describes a very interesting failure of a gear shaft. RTech Materials received a gear shaft (Figure 1) from a gearbox used to drive a ball mill with the request to determine the cause of surface damage observed on the teeth. Figure 1: Gear Shaft.
Basically, they support the weight of the shaft and provide a nondamaging surface to the highspeed shaft that rotates. The lining of a bearing is bonded with Babbitt, which is a soft alloy featuring a lowmelting point. When contamination occurs or failure happens in the lubrication system, the softer alloy wears out instead of the shaft.
In case study 2, following the change of the bearings of the grinding rolls, the plant team was looking for a way to reduce the risk of bearing failure. During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance.
A Multidisciplinary Approach Gets to the Root Cause of a Failed Shaft: An 8inch diameter pinion shaft, which was driving a 12foot diameter bull ring gear on a ball mill, failed after a period of rough operation. The crack originated in the area of a keyway at a clutch hub, Figure 1.
A rolling mill 2 of this company uses an 800 HP motor, which is used to transmit the power to the rolling mill. Motor shaft S1 is rested on bearings B1 and B2. It is coupled with smaller pulley shaft S2 with the help of coupling C1. Smaller pulley shaft is placed on bearings B3 and B4.
Jan 21, 2011· Anyhow between theese two shafts is the 7 meter long shaft with gear couplings which, they say, can compensate for some misalignment. Also when mill in operation large movements of this shaft .
RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming ...
