The Dual-Shaft Mixer Model CDA-500 has a maximum working capacity of 500 gallons. An air/oil hydraulic lift raises/lowers the agitators from/into the mix can. NEMA 12 safety limit switches prevent operation of the drives when the mix vessel or agitators are not in the proper position. All product-contact parts are stainless steel 304 with mill finish and welds ground smooth. The heavy-duty Two-Wing Anchor Agitator and dual-blade High Speed Disperser are driven by 10HP and 100HP inverter-duty motors, respectively. Hinged Teflon scrapers are attached to the anchor for wiping of the vessel sidewall and dished bottom. A tungsten carbide coating on the saw-tooth disperser blades allows the mixer to be used with abrasive materials.
The custom mixer cover includes appropriate connections for ingredient addition, dust collection and a delumping device. A thermowell with type “J” thermoprobe is also mounted through the cover. A 50-psig stainless steel two-zone dimpled jacket enables heating/cooling of the product. The flush tank ball valve mounted on the vessel’s bottom front features a 150# ANSI flange outlet connection, pneumatic actuator and air-powered open/close controls. The vessel is mounted on three legs suitable for use with load cells.
A Ross SysCon NEMA 12 Dual Axis Control Panel houses the Variable Frequency Drives and PLC Controls. A separate NEMA 4 Operator Panel includes a 10" color HMI touchscreen for controlling speed, load and product temperature, as well as saving up to 10 recipes.
