80699.tifCustom Designed Dual Mixer Batch Blending System

This mixing and blending system consists of two mixers: one vertical mixer equipped with a shreader and agitator plus a liquid tank for blending proprietary ingredients with a liquid binder that is then pumped into a 100-cu-ft horizontal, paddlestyle mixer with other ingredients to form the product consistency. This is then discharged into an extruder for further processing. The key to the system is the advanced controls that allow the operator to measure and monitor the materials during each batch mixing cycle. Marion Mixers, Marion, IA 319-377-6371www.marionmixers.com

 80700.tifContinuous Blender

The Vibra blender utilizes a combination of a rotating paddle and material fluidization to blend dry solids with the ease of liquids. Gentle controlled vibration of the mixing trough fluidizes ingredients on entry where a cut and fold mixing rotor provides agitation. Material flows through the blender by gravity, making it completely self regulating to changes of infeed rate. The unit’s simple, rugged design offers dusttight operation, easy cleanout, and years of maintenance-free operation. The blenders are available in capacities up to 1500 cu ft/hr.

80701.tifPowder Induction and Dispersion System

This new Fastfeed model is designed to double inline powder delivery capabilities, offering controlled feed rates from 3 to 400 lb/ min. It provides consistent powder delivery even as viscosity and solids levels increase, ensuring that the system will never plug or foul. The system offers the benefits of an inline, skid-mounted dispersion system that feeds powders and disperses them instantly. It further allows processors to add dry ingredients to mix vessels in a more ergonomic fashion, reducing operator injuries and providing the shear required for today’s changing and tougher ingredients, insuring maximum yield.

80698.tifConical Mixers and Dryers

Conical mixers and dryers offer high mixing accuracy and low shear force to the products being mixed, while requiring low energy consumption and the ability for variable volume filling down to 20% of overall volume design on powders, pastes, and slurries. Many different processing tasks can be carried out simultaneously to include blending, drying, mixing, heating and cooling, crystallization, granulation, agglomeration, and the injection of liquids or gases directly into the batch during processing in a totally enclosed safe environment. Typical applications range from plastics, spices, adhesives, soap powders, and food premixes, to shampoos, toothpastes, gelatins, pharmaceuticals, and chemicals.

80699.tifFluidized Zone Mixer

The Bella fluidized zone mixer achieves fast, high-capacity, low shear, precision mixing of either dry bulk solids or liquids with solids. Regardless of particle size, shape, or density, materials are mixed with a fast, efficient, and gentle action: typical mixing times are 60 seconds or less. A weightless zone created by low-speed counter rotating shafts generates low friction without shear. This makes it ideal for fragile products that cannot tolerate rough handling. Even flakes or spray-dried bodies remain intact. The Bella XN mixer includes twin bomb-bay door openings for fast, efficient discharging and to minimize segregation during discharge. The unit is available in stainless steel for sanitary applications. Custom sizes, finishes, and materials of construction are available upon request.

80698.tifMixers and Blenders with Cantilever Shaft

The Easy-Clean cantilever shaft eliminates one set of bearings and seals at the non-drive end of the shaft. Along with the full diameter hinged and safety, interlocked door, this improves access for cleaning and hygiene. The completely contained mixing media provides an ideal environment for dry, semi-dry, or moist powder applications. These mixers and blenders are available in various designs with a choice of plough, paddle, or interrupted spiral agitator. The Gardner line also includes double cone blenders, continuous mixers, stirred bunkers and processors, and reactor mixers. Kemutec, Bristol, PA 215-788-8013   www.kemutecusa.com
