The most compact direct drive, where electrical conditions permit its use, is the direct connection of a high torque synchronous motor (approximately 160% starting, 140% pull-in and 225% pull-out) to the pinionshaft through a flexible coupling (Drive 3). When plant design makes it essential to locate the motor at a distance from the mill, the drive arrangement may be as shown in Drive 4 or 5

Sand grains will always stick together unless the sand is reasonably fine. While dry sand is loose, wet sand is adherent if the proper amounts of sand and water are used in the mixture. The reason for this is that water forms little "bridges" between the grains of sand when it is damp due to the forces of surface tension.[1]

Aside from the cost barriers to opening mines, there are safety (Bias, 2012) and environmental concerns ("Rare earth mining...", 2012) that must be taken into account. To increase yield and make mining less harmful for the environment, efforts must be taken to minimize the environmental footprint (see Green Mining page) and mining and environmental standards for mines must be either instantiated or more strictly enforced so that mines are held responsible for their effect on the surrounding area (see the solution page for environmental harms of mining)
