This ensures that the machine operator’s hands are clear from contact with moving parts, says the equipment supplier Charles Ross & Son Co.
Mixing equipment supplier Charles Ross & Son Co. (Hauppauge, NY) has added two-handed safety controls for raising and lowering the mixing head of the company’s high-speed dispersers. This safety feature requires that the machine operator push two buttons, and hold those buttons down, in order to operate the hydraulic lift. This ensures that the machine operator’s hands are clear from contact with moving parts.
“The improved Ross high-speed disperser reflects the company’s commitment to the safety of its customers, minimizing hazards whenever possible,” the company said in a press release.
Ross high-speed dispersers are used across many process industries for incorporating powders into liquid. They can handle product viscosities of up to 50,000 centipoise. The dispersers run at tip speeds of up to approximately 5,000 ft/min. The open disc blade generates vigorous flow and a characteristic vortex into which dry ingredients are added for quick wet-out.
