EqUipmENt & sErvicEs Dewatering-drying system features circular fluid bed This dewatering-drying system consists of a circular vibratory screener integrated with a circular fluid-bed dryer to remove over- size and undersize particles while dewatering and drying on-size material. The screener, a 30-in. (762-mm) diameter Vibroscreen model K30-2-SS, together with the 40-in. (1,016-mm) diameter model K40/48-1FBD-SS dryer, removes up to 50 gallons (189 liters) of water per minute, and dries up to 700 lbs (318 kg) of on-size particles per hour. It’s equipped with an imbalanced-weight gyratory motor that vibrates the screening chamber, which is suspended on springs. Kason Corp. (973) 467-8140 www.kason.com through, among other things, state-of-the-art compression elements based on asymmetric rotor profiles, which drastically reduce volumetric losses. Through the optimization of oil injection, flow and temperature, the compression process is kept at the coolest possible temperature, thereby minimizing thermodynamic losses. Other design features to further reduce energy consumption include the use of radial fans with variable speed drive (VSD) regulation, high-efficiency motors and no-loss drains. Extra energy-saving options such as an integrated energy recovery system and VSD for the main motor can provide even greater benefits.

This type of switch is suitable for any situation where it is necessary to check the level of a liquid in a tank, including high or low level alarms, constant level control, pump control, and empty tank detection. A low-voltage AC signal is applied between the probe electrode and the tank wall (or reference electrode in case of a nonmetallic tank). When the liquid comes in contact with the electrode tip, a conductive path is established between the sense electrode and the metallic tank wall/reference electrode. Current flow due to the conductive path is sensed, amplified and used to switch a relay for indication or control purposes.
