Continuous Gravimetric Blenders

Consisting of one to eight feeders and a central microprocessor based controller, the K4G and ProRate™ Gravimetric Blender continuously meters raw materials accurately into a central station hopper.

K4G Continuous Gravimetric Blender

The K4G Continuous Gravimetric Blender System is designed with the specific requirements of the plastics processing market. The compact design and low space requirements of the K4G integrated system allow four or six feeders with Coperion K-Tron receivers to be easily grouped around an extruder inlet. Single stations are also available.

A wide variety of standard Coperion K-Tron feeders can be integrated into the K4G single-point weighing system, depending on the applications feeding requirements. The K4G incorporates single screw feeders, Bulk Solids Pump feeders and Coperion K-Tron receivers for handling free flowing bulk materials, and twin-screw feeders and KTron receivers for the handling of powders and non-free-flowing materials.

ProRate™Continuous Blenders

Capacities:

• Coperion K-Tron's ProRate I is a gravimetric feeder designed with selection of five interchangeable auger sizes, allowing for varying capacities up to 1,175 pounds per hour.
• Coperion K-Tron's ProRate II is gravimetric feeder designed with 3-inch diameter auger providing high capacity feeding up to 3,500 pounds per hour.

Features:

• Cylindrically hoppers with a 60° cone to assure fast material discharge.
• High performance load cell assembly with a nominal 12-inch base frame provides an accurate weigh signal to the controller.
• Center station 4 position and 8 Position bases are available. They are designed for use with either the ProRate I/Gravimetric feeders or high-volume ProRate II/Gravimetric feeders
• Modular scale platform assemblies provide support by two legs, with adjustable leveling bolts, and bolt-on attachment to the base station.
• Continuous loss-in-weight controller is a multimode, microprocessor based, process weight controller.

Gravimetric Batch Blenders: Available in 2.5KG, 5KG and 12KG sizes.

Each of the materials are dispensed sequentially into a common weighing hopper in the desired proportions. The weighed materials are then released into a separate mixing chamber which provides the most consistent homogeneous blend of any batch type blender.

Features:

• Ingredient accuracy of +/- 0.02% per batch at highest accuracy setting
• Integral loading platform for mounting vacuum receivers
• Clean-out system to facilitate quick and easy product changeovers
• Attached air hose and nozzle for cleaning
• Fast acting V-gate valve on each ingredient hopper
• Support for a wide variety of communications protocols
• Inventory of entire blender and each individual hopper
