"Foundation designs are integrated into the type certification for some turbines. Where this is the case, the foundation design must be evaluated for the external conditions for which it is intended. Poor geotechnical investigation and foundation design have led to delays and cost overruns at European wind farms (Gerdes et al. 2006)."
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
good design practices for concrete anchorage of rotating equipment . These recommendations can be applied to all Flygt pump installations but spe-cific emphasis is placed on vertical, dry pit instal-lations . Failure to follow these good design and construction practices may result in higher levels of noise and vibration than desired . A licensed
Building on the Right Foundations One of the largest vertical turning and milling centers in the country will be installed in this Cincinnati-area job shop. Although installing the foundation for this huge machine was a massive undertaking, the company is building on other "foundations" as well.

A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where fixed-foundation turbines are not feasible. Floating wind farms have the potential to significantly increase the sea area available for offshore wind farms, especially in countries with limited shallow waters, such as Japan.
