Compact batch blenders for feeding up to 8 ingredients in your plastics compounding process

Coperion K-Tron Gravimetric Batch Blenders dispense material sequentially into a common weighing hopper in the desired proportions. The weighed materials are then released into a separate mixing chamber, which provides a consistent homogeneous blend. They include an advanced metering and weighing system that accurately controls every ingredient of every batch to the desired amounts and is not averaged over multiple batches. The standard blenders are intended for use over an extruder inlet, where the extruder acts as the flow control.

Elements of a gravimetric batch blender

Available Models

The Coperion K-Tron Gravimetric Batch Blenders (GBB) are designed and constructed of heavy gauge steel (11 gauge steel) to withstand the most rigorous of operating conditions. The load cell is overload protected and guarded from physical damage. Each blender is constructed with high load bearing continuous welding and is protected against vibration and shocks. All blenders include self-optimizing software to give you the most efficient output on every recipe. Continuous mixing of the bulk materials means the mixing times do not need to be adjusted and the consistency of every mix is guaranteed.

There are a wide variety of models and configurations available, depending on the number of bulk materials to be fed and the size of the batch.
