RENK rolling mill bearings in the WG range are designed for extreme axial strain. They were developed primarily for the mounting of rolling mill drive units and large electrical machines in which high axial loads occur at low speeds and a high level of protection against damage must be ensured at extreme loads.
The grinding mill is at the heart of a mining operation but a poorly designed or constructed foundation will not only affect grinding mill performance but potentially render the mill out of action – thereby costing millions of dollars in lost production. The following advice will help ensure the foundation is right before you install a new mill.
