Comet Automation Systems, Inc., Introduces Comet GraviMix Micro Blender

DAYTON, Ohio, (March 4, 2003) -- Comet Automation Systems, Inc., a leading manufacturer of corrosion-free stainless steel auxiliary equipment has introduced Comet GraviMix Micro Blender: an efficient gravimetric blending system with the unique "Auto-Pulse" system. GraviMix Micro, is a small, economical and user-friendly blending system.

The GraviMix Micro gravimetric blender is a small, efficient metering, weighing and blending system. It can be installed directly on the processing machine, and is designed to accurately blend free-flowing thermoplastic materials. It is especially suited for use on injection molding, small extrusion and blow molding machines where consistency and high quality finished products are required.

The GraviMix Micro gravimetric blender meters, weighs and blends up to four components, generally virgin, regrind, masterbatch and various additives. The GraviMix Micro is equipped with removable hoppers for each component. The components are metered individually using pneumatically operated metering valves. The GraviMix Micro gravimetric blender is equipped with a unique Auto-Pulse system that maintains accuracy even on small quantities. Each component is dispensed directly into the weigh pan that is supported by a highly precise loadcell system. When all the components are correctly weighed, the complete batch is discharged into the mixing chamber. An efficient, pneumatically-driven horizontal mixer provides a uniform blend. A level sensor in the mixing chamber controls the metering and blending cycle.
