The drive behind your success A Hägglunds hydraulic direct drive is a drive system beyond the ordinary. In far less space than other drives— and with far less weight and complexity—it delivers flexible, reliable power. With a Hägglunds drive, your machine has unlimited access to high torque. Yet it's also protected from torque stresses.
In this mill, the drive shaft is positioned vertically and screens and hammers are positioned horizontally. Material successfully reduced in size to the diameter of screen holes or smaller, are carried by gravity outside the mill and thence …

• Thrust roller bearings – Thrust roller bearings for rolling mill applications are available in cylindrical, spherical and tapered designs. Thrust bearings are ideal for applications experiencing heavy axial loads, such as mill stands, screw-down systems and piercing mills.
Failure Mechanisms, Arrangements and Applications Steam turbines are fundamentally the same regardless of whether they drive a simple 500 shaft horsepower (SHP) fan or drive a 1,000 MW generator. In all cases, steam is expanded through rows of stationary and rotating blading which convert the energy in the steam into mechanical energy.
