JULY 2018 • E&MJ 69 EQUIPMENT GALLERY dition, the hammer delivered up to a 15% increase in penetration rate, with smoother collaring and straighter blastholes, Sand- vik reported. It also enables the drilling of larger holes at the same speed as a smaller hole with a standard hammer. Separately, Sandvik introduced the RR441 rotary bit, an improved version of the RR440 and designed to last up to 140% longer than predecessor competi- tion, the company reported. The RR441 provides excellent class-leading bearing life, simplifi cation of the bearing system, improvements in air fl ow, and superior wear protection in soft rock applications, Sand- vik reported. Sizes range from 171 mm to 406 mm. It comes equipped with an im- proved durability dual-seal journal bearing. Oxygen-based Service Solution for Gold Leach Afrox announced Goldox, a fully integrat- ed end-to-end product service offering for the global gold mining industry. It is re- portedly designed to optimize metallurgi- cal gold leach using oxygen, and provides a test program that determines oxygen demand requirements; the supply of ox- ygen via vacuum pressure swing adsorp- tion (VPSA) tech; an oxygen reticulation network; maintenance; and the requisite oxygen for a set period of time. Linde Engineering's oxygen VPSA systems will enable improved gold recoveries, higher plant productivity and throughput, great- er energy effi ciency, and superior environ- mental performance, Afrox reported. 'Economical' Small Pipe-joining System Victaulic announced the QuickVic SD Installation-Ready System, a plain end- pipe joining technology designed for use on carbon steel systems sized 2-in./ DN50 and down. It is the most econom- ical and effi cient pipe joining solution for small diameter systems, offering a signifi cant total-installed cost savings, Victaulic reported. The system includes Installation-Ready couplings, fi ttings and valves, and the PC3110 Cut & Mark Tool. Available in sizes 0.5-in. to 2-in./DN15 to DN50, the products can be used on Schedules 10 through 80 carbon steel pipe and have a maximum working pres- sure and temperature rating of 300 psi and 250°F (with the EPDM gasket).

R OTAT I N G S H A F T S E A L I N G E X P E R T S A Better Seal. PRECISION FIT. SEALS EFFECTIVELY. LONGER LIFE. Patented Product The PackRyt® Sealing System is a unique stuffing box sealing arrangement that incorporates a bearing and flush channel system together. The one-piece bearing and lantern ring, made from the same material, ensures the lantern doesn't spin, collapse, or expand in the stuffing box which can result in failure. Our patented system brings shafts into concentricity and keeps them there, significantly increasing sealing reliability. EASY TO MIMIC. IMPOSSIBLE TO MATCH.
