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 ABB's experience in optimizing gearless solutions
All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
AG and SAG mills can be designed for dry or wet grinding. The bearings are hydrostatic slide or slide shoe bearings. Usually, AG and SAG mills have a gear rim/pinion or direct drive. Our p rodu ct portfolio includes sizes from a laboratory scale to a diameter of 10 meters or more. For transport reasons, these mills consist of several flanged ...
Type 2 open gear drives typically consist of an actuator, pinion and a gear or a series of connecting gears used to transmit continuous loads. They are normally used to power stationary or semi-stationary equipment such as kilns, grinding mills, rotary furnaces, dryers, debarkers, rubber mills, paper mills and finishing mills.
Grinding Optimizer – with the RockSense on-belt rock size analyzer, MillSense charge analyzer, and PSI particle size analyzer – gives you a complete solution for optimizing your entire grinding circuit. The system stabilizes the process, maximizes throughput, improves control of particle size, and provides accurate on-line analyses of the ...
A gear drive is one part of a power system which has certain load characteristics peculiar to the specific application. The gear drive package itself is a subsystem within the overall system and in addition to transmitting the load demands of the overall system, it is subject to additional load variations generated or contained within itself.
