For example, Ross’s 200-gallon Double Planetary Mixers are equipped with High Viscosity (HV) Blades (US Patent No. 6,652,137). Designed to rotate on their own axes while orbiting the vessel on a common axis, these helical blades are ideal for batching heavy pastes and putty-like materials as high as 6 million centipoise (cP). The mixer’s robust processing capability is greatly enhanced with the use of recipe controls which transforms the entire mixing/discharge/cleaning cycle into an automated, simplified process with a very high degree of repeatability. The standard module allows users to write up to 10 recipes each with 10 process sequences based on agitator speed, time, temperature and vacuum/pressure level set points. A programmable pause can be built into any step in order to load raw materials, take samples or perform other activities. Other configurations (i.e. 20 recipes using 40 steps) can be supplied as well.
Ross SysCon, the controls division of Charles Ross & Son Company, designs and builds PLC-based recipe driven systems for all other Ross equipment, including Ribbon Blenders, Vertical Blenders, Tumble Blenders, High Shear Mixers, Planetary Dispersers, Multi-Shaft Mixer/Reactors and Pumping Skid Packages.
