CHARLES ROSS & SON CO.: Explosion-Proof Stations
Charles Ross & Son co. offers turnkey solutions for processing a wide range of applications in hazardous or classified environments. By weighing, mixing, and discharging on a common platform, the solution reportedly offers improved safety and a more efficient batching process.
One example of a turnkey package is the pictured 10-gal double-planetary mixer and discharge system. Heavy-duty helical mixing blades—designed for high-viscosity pastes, gels and putty-like materials—are raised and lowered via an air/oil hydraulic lift with explosion-proof electrically operated solenoid valves. The motors on the mixer and discharge system, limit switches, junction box, local operator station, platform scale and weight indicator are also all explosion proof. All hardware in the mixing zone is lock wired, and product wetted welds are dye-penetration tested.
The vacuum-rated mix can is internally machined, reportedly providing uniform stirrer-to-vessel clearances of 1/4 to 1/2 in. Other features include a 50-psig stainless steel jacket for heating/cooling, 2-in. flush cove-cut discharge valve, RTD thermocouple on the sidewall, and a grounding drag strap. Caster wheels on the vessel and V-tracks on the platform reportedly allow for easy movement between the mixer, weighing station, and discharge press.
