Jun 01, 2012 A reading of electric meters indicates that 3250 kW electricity is consumed by the main driving motors of the raw mill. Total energy output out consists of the energy of raw materials leaving the unit and heat loss from shell of the mill. The heat lost is determined to be 4422.9 kW.
The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity. Reversing direction evens out wear on liners with symmetrical profile and prolongs operating time. The SAG mill was designed to treat 2,065 t h 1 of ore at a ball charge of 8 volume, total filling of 25 volume, and an operating mill speed of ...
Jan 01, 2014 As shown in Tables 1-4, the fault-prone components on these units are the gears, bearings, couplings, shafts, impellerblades and electric motor. Figures 3 and 4 respectively show the schematic and pictorial representations with the positions of the various VCM sensors of the coal mill main drive assembly, bag house fan and booster fan.
To cope up with increasing kiln capacities, twin motor dc drives are used. Two dc motors with separate pinions drive the same gear wheel at the periphery of the kiln drum. Function A cement mill is a drive used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.

The large series accommodates power ranges from approximately 1,300 to 5,500 kW, while the small series is perfect for coal mills with a power ranges up to 1,500 kW. Refined for coal mills We developed the small series of MAAG GEAR WPU Gear Units specifically for coal mills in cement, mineral and thermal power plants.
Low vibration means less noise, wear and tear. The flaking mill and drive motor are mounted on a common base supported by vibration mounts resting on the floor. No vibrations are transmitted to the building structure. Noise is ... Main drive Feeding drive Mixing drive kW kW kW 75 - 90 0.37 1.1 Approx. Weights net gross by sea kg kg kg 8940 9420
More stringent specifications regarding motor vibration call for maximum velocity levels of 0.1 in.sec on the housing and 1.5 mils of displacement vibration on the shaft. The limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment.
minimum clearance location, and maximum at the maximum clearance location. When the extrusion gap clearance varies dynamically due to factors such as runout and vibration, the rate of damage to the rotary seal typically increases, because the extruded seal material experiences increased strain. 3 For example, see U.S. Patent 6,416,225.
Cement Mill Motor High Temp Page 1 Of 1. Mar 06 2009 cement mill motor high temp Hey Due to a problem in our cement mill motor cooling system temperature of the winding temperature increased to the high limit 120 C solving the problem of the cooling system will take few days but till that time we dont want to keep the mill stop
Dec 30, 2020 The main factors affecting the milling process are the mill dimensions length and diameter, the critical speed, the mill lining design, the ball filling ratio and the maximum ball size. The residence time of the ground material inside the mill is another
Overview. The cement kiln, also called cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment for the new dry type cement production line.This cement equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.
I need help to understand the vibration readings of this motor. The motor specs are 6300 KW driving a Ball mill cement mill Speed is 1194 rpm actual speed with tachometer NDE bearing is NU 1052 DE bearing is NU 248 inside DE bearing is 6048 outside The problem here is that the axial vibration goes high instead of 1.5 mms maximum ...

The Vibratory Disc Mill RS 300 is suitable for the extremely quick, loss-free and reproducible grinding of medium-hard, brittle and fibrous materials to analytical fineness. It is possible to process 1, 2, 3 or 4 samples simultaneously. Thanks to the robust universal drive shaft, which sets the grinding jar into a 3-D motion, this mill accepts grinding set weights of up to 30 kg.
