SCREENING RECENT ADVANCEMENTS Technologies that can make a difference at your operation Processes fines in hot screening applications HAVER BOECKER offers the H Class vibrating screen for fine particle screening The company says the units high frequency vibrations efficiently screen hot dry materials for consistent product output The heavy duty stationary machine is designed to be safe for use in unreinforced structures since the movement is confined to the media which moves with a fast small stroke to screen materials through openings ranging from 1 2 in to 100 mesh The machine offers two variable speeds the Running cycle operates at 42 to 48 hertz to screen particles and can be modified to an operations specific needs while the short Burst cycle increases the vibratory motion to 60 hertz to clean the screen preventing blinding and increase productivity says the company The modular design uses pre engineered components which allow the machine to be configured based on an operations machine size requirements www havercanada com Urethane screenwear products allow for impact resistance ASGCOS cast urethane screenwear products help to prevent abusive material and conditions from hindering the productivity of quarry operations The screen wear products feature a higher load bearing capacity according to ASGCO Additionally polyurethane material tends to maintain its properties when compounded ASGCO offers screen feed box liners patterned for a direct replacement of the current liner configuration being used The liners can have various sized and shaped ceramics inserted to increase longevity The company also offers screen side wear liners which are boxed in with mild steel or hard plate to prevent premature edge wear or damage Bolt patterns sizes and thicknesses can be customized to increase the wear life www asgco com Measure performance of vibrating machine With Vibe2know from SCHENCK PROCESS users can determine a vibrating machines current performance The user inserts a smartphone into the specially designed mount and attaches it to the equipment The app then immediately measures vibratory amplitude frequency oscillating angle and operating speed and enables the user to visualize the vibrating machines motion pattern By getting a quick indication of these key parameters operators can avoid a sudden production outage and plan a timely maintenance intervention Vibe2know is available via app stores for iOS Android and Windows and includes a brief tutorial Attached to equipment by means of a magnet on its reverse side it is robust and dust tight specially designed to withstand the accelerations of a vibrating machine and any environmental conditions www schenckprocess com S10 PIT QUARRY January 2018 pitandquarry com
