Fines recovery plant offers easy setup
EIW’s (Eagle Iron Works) Hawk fines recovery plant consists of a sump, a pump, hydrocyclones and a dewatering screen that are configured in a modular, compact design. The plant can be used as a standalone solution for fines recovery or as part of a larger tailings management system. According to EIW, the Hawk captures ultra-fine solids from process water in the waste stream and discharges a drip-free material that is conveyable, stackable and potentially saleable. The Hawk will help reduce the solids that go to settling ponds, EIW adds, thereby reducing the frequency with which ponds need to be cleaned out. The modularity of the plant enables quick and simple setup, the company adds, and its compact design allows for maximum utilization of land resources.
Modular plant simplifies maintenance, maximizes production
McLanahan‘s UltraWash can make three aggregate and two sand products while accepting capacities up to 400 tph. It has both a single-process water feed point and a single discharge point. The modular design offers a compact footprint, the company says. The UltraWash system includes several features to simplify maintenance and maximize production. The underpan of the sizing screen features a fines forward slide. This steel tray spans the width of the bottom deck of the sizing screen and facilitates the diversion of a proportion of raw fines into the coarse sand processing stream to help balance downstream equipment and optimize plant capacity. Additionally, an EZE-Riser lifting pedal and locking mechanism allows for simplified feed pipe disconnection and the needed clearance for pump removal when maintenance is required. The UltraWash feed hopper and conveyor can be upgraded to come with tracks for easier conveyor maintenance.
Portable wash plant suitable for several applications
Superior Industries‘ Spirit wash plant is capable of producing as many as five products. The Spirit carries a 6-ft. x 20-ft. Guardian horizontal screen, plus a sand production module and an ultra-fines recovery module. According to Superior, the first wash module uses a cyclone to size and separate material for a traditional sand product. A dewatering screen ensures it’s instantly saleable off the discharge chute, the company adds. Also, depending on the deposit, an optional ultra-fines recovery module washes out minus 100 to minus 400 fines for microfine material, which is saved from being lost to a waste pond. Applications for the new portable plant include operations with settling ponds, crushed aggregate, sand and gravel, dredging and frac sand.
