the model considers also the major effects of mill body, foundation and soil. The mill is modeled as a rigid body. Spring elements at the center of the mill consider the stiff-ness of the mill and its bearings. The simplified foundation is modeled by volume elements and considers the weak-ness of foundation and soil.

Grinding Mill FOUNDATION. Adequate foundations for any heavy equipment, and in particular Marcy grinding mills, are extremely important to assure proper operation of that equipment. Any slight settling of foundations will cause bearing and gear misalignment, resulting in excessive wear and higher maintenance costs.

Material with high stickiness creates problems in all aspects of the grinding process, including feeding (e.g., making metering into the mill difficult), grinding (e. g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials.

This trend culminated in the decision to create a facility for machining work too large and heavy for most other shops to attempt. The Carnaghi machine is scheduled to be operational in the third quarter of 2012. The building has enough space for a second large, gantry- or floor-type boring mill. This means there is still room to grow.

The design process has changed dramatically with computers though. A typical FEA of a grinding mill that would take about 3 hours on a minicomputer in the late 80's takes about 3 minutes on a laptop computer today. This allows the analyst to add more detail to the models (increased accuracy) and check multiple options to optimize design …
