Fixed, modular, and mobile sand plants
McLanahan says its Ultra Sand Plant can produce as many as three separate products without a classifier. The company says a combination of cyclones and dewatering screens results in a drier construction sand product, so less usable sand is lost to waste. The company offers its plants in fixed, modular, and mobile configurations for washing, organics removal, and fines recovery.
Alternative to wet washing
Sturtevant says its Whirlwind Air Classifier provides an alternative to wet-washing minus-200 mesh fines from crushed stone. The classifier’s self-contained design incorporates an internal fan and rejecter-blade classification system. Material is belt conveyed by gravity into and out of the classifier and discharges from one single outlet. Rotating selector blades control the particle size of the fines removed by the air. Benefits include water conservation, reduced land requirements, elimination of settling ponds and dredging, and a secondary saleable fine product.
Portable crushing and screening plant
The new Terex Cedarapids CRC380HLS portable crushing and screening plant’s design is said to allow the cone crusher to be constantly choke fed, maximizing production. The high-lift screen and cone hopper overflow system allow a large head of material to build up, force feeding the cone crusher. The large cone hopper and overflow chute buffer feed variations and prevent material from backing up to the screen. A gross throughput of up to 1,200 tons per hour is possible, according to the company.
Higher energy per blow
Tramac says its new V4500 heavy breaker was specifically engineered to provide a higher energy per blow. The breaker features blank-firing protection to prevent metal-on-metal contact, a pressure regulator valve to prevent overpressure and accidental overflow, reinforced suspension to absorb vibration, an automatic pressure regulator to ensure constant operation despite variation in flow or temperature, an automatic frequency adaptation system, increased striking from an energy recovery feature that captures rebound energy for the next blow, and an automatic greasing system.
Versatile impact crusher
Universal Engineering says its VersaCap primary impact crusher is designed to be versatile and reduce quarry shot limestone. Features include reversible hammers with a protruding leading edge for longer wear life at higher reduction ratios and adjust-on-the-fly capability. The “Shot-Rock” primary is available in three sizes.
Transforms fines into saleable material
W.S. Tyler says its new Haver palletizing disc transforms wasteful fines into a transportable, saleable product. The disc offers variable side-wall height, speed, and inclination. Its direct-drive technology works without a gear box and hydraulic coupling, eliminating the maintenance required for traditional components. The efficiency of the drive is said to minimize energy losses, reducing total energy costs up to 5 percent.
