Oct 22, 2016 Motor speeds will vary from 225 rpm to 450 rpm. The motor and pinion shafts are connected together through a flexible coupling. This drive is the most compact, resulting in minimum floor space. In cases where motors must be placed away from the mill a pilot shaft extension with flexible couplings can be provided

The standard selection method can be used for most motor, turbine, or engine driven applications. The following information ... Select a gear coupling to connect a 500 HP, 1170 RPM electric motor ... ROD AND BALL MILLS DirectoronL.S.shaftof Reducer, with final drive Machined Spur Gears

New ball mill drive system with the prototype energy-saving SMH motor [ 37 ]. As in the case of the SAS motor, the new drive system does not have a gearbox or a starter. The start of the charged ball mill is very violent, as shown in the graphs from the industrial HIOKI logger ( Figure 5 ). Figure 5

Designed to deliver exceptional levels of performance and value, David Brown Santasalo ball mill drives are optimised for primary and secondary grinding applications. Extensively field tested and proven in harsh cement applications, our mill drive gearboxes cover all grinding applications up to 10 MW per drive and we have single, double and triple reduction gearing available depending on the required ratio and motor

side-transmission ball mill. The main fault is about t he breakdown in the elastic rubber coupling of the. transmission system. It is found from the analysis of the real cases and data that the

The toothed couplings installed between the main motor and the gear unit, as well as between the gear unit and the ball mill, transmit pure torque from one component to the next. In addition, they compensate for thermal expansions and mechanical deflections resulting from operating conditions

2 GEARLESS MILL DES The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record

Safety devices, such as coupling guards have been removed for illustration purposes. If the main reducers are not present, the inching drive can be connected via a through shaft in the main motor or the free end of the mill pinion. Data Requirements for Incher Selection In order to design an optimal inching drive for a given application, the gear

May 16, 2013 Motor is coupled to the gearbox with a grid coupling Motor bearings are white metal as well as the pinion. we had a 7 day forced outage due to vibration manifesting only on motor bearing.What was confusing so much is that motor light run was perfect below 2mm/s as well as when the pneumatic clutch is diusengarged

The normal operation of the ball mill uses the motor to drive the ball mill to perform rotation operation. The motor drives the ball mill to directly connect the pinion through the elastic pin coupling and drive the big gear ring to realize the operation of the ball mill

Jul 28, 2015 Grinding Mill Gear Assembly. We will begin with the mill’s bull gear assembly and work towards the motor, The BULL GEAR, sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill. By mill we refer to Ball Mills, Rod Mills and SAG Mills

With the new baring gear coupling installed, the mill motor starts up whilst baring is taking place, and the mill load is in motion. The baring gear coupling slides back in a keyway and a limit switch simply stops the baring motor. The self-disengagement clutch is a directionally actuated freewheel clutch

The Copper Mountain ball mills are 7315 mm [24 feet] in diameter and 12040 mm [39.5 feet] long. They are overflow discharge ball mills with inside diameters of 7315 mm [24 feet] and grinding lengths of 11887 mm [39 feet]. Each Ball mill is also driven by two 8,500 horsepower ABB motors. Figure 3 - The 24’ x 39.5’ ball mill

customised coupling products. SKF Cou - plings cover a wide range of coupling types, sizes and capacity ratings for many applica - tions and factory environments. For large, heavy duty applications, SKF has large size couplings. These couplings, which provide optimum contact with the shaft, can accommodate high torque values

Mar 29, 2007 To tell you about the mill, its driven by a 250hp, 415V 1440rpm motor connected to a SEW eurodrive gear box of 10:1 ratio via a Fluid coupling. The gear box is connected to the pinion of mill by a gear coupling. The pinion is driving a bull gear which makes the ball mill rotate at 14rpm
