Ross Tilted Design Double Planetary MixerRoss introduces new Double Planetary Mixers with a slightly tilted configuration for more effective and complete discharge of flowable products. Double Planetary Mixers are versatile equipment used in the preparation of pastes and gels, as well as granulations and free-flowing dried powder blends.

Pictured is a 15-gallon Double Planetary Mixer designed to operate at approximately a 5-degree top forward tilt. An air/oil hydraulic lift is supplied to raise/lower the stirrers into the removable vacuum-rated mix can. During mixing, a glass sight/charge port and tank light on the vacuum hood allow the operator to check on the batch and conveniently add raw materials without interrupting the agitation. Stainless steel 316 rectangular stirrer blades are driven by a 5 HP inverter-duty motor. Detachable sidewall and bottom scrapers are also supplied.

The 50-psig heating/cooling jacket on the vessel is insulated and sheathed in stainless steel. Batch temperature is measured from a thermowell with an RTD thermocouple on the side of the mix can. After the mixing cycle, product is discharged through a 3-inch diameter Teflon plug installed via heavy-duty tri-clover clamps towards the front of the mix can. The raised base provides a 28-inch clearance beneath the outlet and is suitable for 12-inch diameter receiving vessels.

The mixer package includes a Liquid Ring Vacuum Pump complete with sealed water reservoir, air-to-air heat exchanger, and built-in shell and tube condenser. A Hot Oil Temperature Control Unit is supplied as well. The NEMA-4X Control Panel specially designed for this mixer integrates start/stop and speed controls, speed display, digital temperature readout, cycle timer, chart recorder, vacuum pump on/off controls, vacuum gauge, E-stop, fused rotary disconnect and control power transformer . Customers have the option to strategically source such auxiliary equipment from Ross to ensure complete compatibility, hasten installation, and start production sooner. For more information, visit
