At the very heart of the new Stowell Concrete plant, the Columbia CPM+60 machine has a fl at steel production pallet size of 1400x700x15mm, chosen primarily due to the unique Columbia Vibration Technology (CVT) that provides controlled mould vibration, accurately guided in a completely vertical motion. The CVT results in longer mould life, uniform distribution of aggregates, reduced cement usage, precise product heights and product versatility. Columbia's patented CVT combines over 80 years of innovative engineering and field-proven capability to enable the highest quality and most comprehensive range of products in the world. The CPM+60 is an easy to operate machine with user-friendly HMI/Compact Logix control and machine adjustments made from the HMI and full menu screens for quick machine set up. In changing from product to product (including any mould change requiring a height change), the machine makes the change automatically. Product change-over is recipe driven with a push-button control and tool-less agitator and strike-off plate removal.
The machine also features forced oil lubrication, a laser probe to control the feed drawer material level, full isolation between rear feed drawer section and machine centre section vibration, hydraulic linear agitation, remote valve stand, electronic product height control, product reject control and automatic mass control.
