Blastcrete Equipment LLC, a long-time manufacturer of shotcrete and gunite mixers and pumps, now offers a refractory paddle mixer that delivers fast mix times while working with mixtures that include aggregates up to a half-inch (13 millimeters) thick. The hydraulic machine mixes as much as 500 pounds (227 kilograms) of refractory castable in about two minutes and performs well in form-and-pour jobs and other applications involving precast shapes, mortars and grouts.
The mixer’s oversized, heavy-duty, chain-and-sprocket drive system provides years of reliable use under harsh conditions. It also features a pair of easily accessible levers to control the hydraulic dump and operate the system in both forward and reverse.
Customers can pair the 1,900-pound (862-kilogram) machine with a variety of electric power options for safe indoor use and to meet global needs. Customers have their choice of three electric motors: a 10-horsepower (7.5-kilowatt) electric motor with starter disconnect, a 240- or a 480-volt, 60-hertz motor, or a 380-volt, 50-hertz motor. Customers also can choose to power the paddle mixer with a 14-horsepower Kohler gas engine.
The 4-foot-wide (1.2-meter-wide) mixer’s trailer features a single axle for easy towing, or it can be skid-mounted.
Customers can use the paddle mixer with Blastcrete’s patented DustAway system, which consists of an innovative bulk bag design that attaches to the mixer to contain dust as the mixer fills. DustAway helps businesses meet OSHA crystalline silica dust regulations by controlling dust to within OSHA-permissible exposure limits.
For larger refractory jobs, Blastcrete also offers a 1,000-pound refractory paddle mixer-pump, the RMX-5000 and a refractory pan mixer that can mix as much as 2,200 pounds in less than two minutes.
