FSC Federal Supply Codes Government

Federal Supply Class (FSC) codes are used to group products into logical families for management purposes The four-digit fields (defined within Cataloging Handbook H2-1) are used to group standardization documents and their products into logical families Similarly Standardization Areas refer to categories for engineering technologies disciplines and practices that do not fall under a FSC get price

Rod Mills How Do They Work?

The heavier rods acting upon the lifters and liners result in greater wear on the mill liners Rod mills normally carry 35 to 65% rod charge by volume The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill and (2) keeping the rod charge low so rods will not work their way into discharge get price
