EQUIPMENT FOCUS CONVEYING MATERIAL HANDLING PUMPS Handle high volumes with ease Eriez HVF mechanical feeders are rugged and low profile featuring a compact straight line design and quick flow rate for optimal performance Each feeder is a spring coupled two mass vibrating system with a motor driven eccentric shaft The hand wheel adjustable variable speed sheaves help achieve an accurate control of flow rate for the feeders which can be up to 60 ft per minute HVF feeders can also control up to 2000 tph The feeders adjustable angle rubber springs can be removed and replaced in less than two minutes the company says they are also designed to amplify the trough stroke resulting in low horsepower requirements The motion of the troughs can be adjusted to accommodate the flow rate for specific applications and a variety of trough sizes and types are available A standard three phase motor mounted behind the base frame of the HVF feeder is belt connected to the factory set variable pitch sheave which drives the eccentric shaft at approximately 1100 rpm www eriez com New lagging adhesive complement pulley line Flexco introduces Flex Lag Medium Ceramic pulley lagging and Flex Lag adhesives The Medium Ceramic pulley lagging features 39 percent tile coverage This complements the existing Full Ceramic and Diamond Ceramic which provide 80 percent and 15 percent coverage respectively the company says Adhesives with a two part cold bond system round out the Flexco offering by providing the bonding system to complete the lagging installation Flex Lag Medium Ceramic pulley lagging can be used in dry wet or muddy applications where slippage can New stacker increases stockpile capacity KPI JCI and Astec Mobile Screens has released a new 170 ft long SuperStacker its latest model of telescoping stackers designed to minimize stockpile segregation and increase stockpile capacity The new generation SuperStacker line eliminates the e chain reducing field maintenance and providing smoother operation and better reliability the occur The horizontal grooves in the lagging trap and deflect water debris while the molded ceramic buttons grip the belts underside for positive traction and no slippage The lagging comes in strip widths ranging from 35 to 101 in to match pulley face widths or 18 to 84 in to match belt widths www flexco com company says By controlling the extension of the stinger conveyor radial travel and conveyor incline As a result layered windrows will be built minimizing stockpile segregation Desegregated stockpiling means suppliers produce more material that matches specification resulting in no re blending and less discounting the company says This new model also features an updated more user friendly Wizard Touch automation control system which allows for more stockpiling options and a higher quality product The easy to use automation system comes with factory pre set programming and provides the versatility of customizing in the field www kpijci com 56 PIT QUARRY April 2014 www pitandquarry com
