Their New Amsterdam quarry is capable of producing 2,000 tons per hour, said Brad Mulzer, co-owner and manager at Mulzer Crushed Stone.
A Deister pan feeder feeds from the dump box onto the separate 6 X 20 grizzly scalping screen before being crushed by a 50 X 60 jaw, said Mulzer
.A pan feeder is located directly beneath the jaw.This design eliminates plug-ups under the jaw when making larger rip rap."Because the pan feeder is the exact width of the jaw crusher, it allowed us to not have a chute to funnel to a belt; no need for bottlenecks," said Mulzer
."This was a big safety issue for us."From the pan feeder, the material is conveyed to a Deister 7 X 16 screen, then to a Deister 8 X 20 screen which, when used together, either produce a wide variety of products from minus 24 in. rip rap to a 4 in. plus product or the material is moved to the secondary plant's surge pile.This sized material is frequently used in river bank stabilization along locks and dams on the Ohio and Kanawha Rivers, he
"This cone takes whatever's in the surge pile, 12 in. by 1 1/2 in., and brings it down to minus 4 in. by 0 in.," said Mulzer
."It then goes to a 500-ton surge bin which feeds two completely separate sections of the plant."In keeping this portion of the processing separate, the plant is capable of producing several different-sized materials simultaneously."Another reason for having the two sides is that if one side of the plant breaks down or we're having a problem, we can still process material using the other side," said Mulzer
"The plant was designed so we can do maintenance by walking the entire plant without having to come down to the ground to go to different sections of the plant," said Mulzer
.Designing and erecting such an extensive plant entailed the involvement of several different manufacturers.The primary plant was built by Lansing, MI-based Hartman Fabco
while the secondary, tertiary and quaternary plants were created by Process Machinery, Inc.
, a manufacturer from Shelbyville, KY.Yet another manufacturer, St. Louis-based E.F. Marsh Company
, built a rinsing plant for Mulzer Crushed Stone
.The rinsing plant is the quarry operation's last handling of the material before it is loaded onto barges for transport."We use a loader and haul trucks to take material from our stockpiles and dump it into the rinse plant hopper," said Mulzer
."The material is then conveyed to two 8 X 20 Deister rinse screens where fines are rinsed out of the product before being loaded onto barges for shipment."Eagle Iron Works double de-watering screws remove solids from rinse water which returns to a settlement pond.Mulzer
Crushed Stone's New Amsterdam location might seem somewhat imposing, but it's merely one of their quarry operations.
