| Acromet’s vast range of Accurate and Reliable Volumetric feeders, coupled with state of the art Weigh Process controllers, can deliver superior accuracy and reliability to meet any powder handling requirement. The success of Acromet COAX Volumetric Feeders, due to the smooth pre-feed product conditioning device (which provides uniformity of discharge rate), reduces the demands on the control system for compensatory action and thus ensures smoother control with correspondingly improved accuracy. Systems are designed & engineered for optimum performance to achieve the best possible accuracy within the design parameters. Gram accuracy can be achieved in batching applications and accuracies of 0.25% or better can be achieved in Continuous Loss in Weight systems. Acromet can provide accurate Gravimetric systems in the following configurations:
"Continuous Loss in Weight"
Continuous monitoring and adjustment of the feed rate using closed loop microprocessor control. Simply select manually or remotely a specified flow (kg/hr) and the system will maintain and adjust the Feeder to the desired set point.
"Batch Loss in Weight"
The feeder and hopper are continuously weighed against a pre programmed reduction in weight. Feeding ceases upon reaching the predetermined set point (g,kg,tonnes). Dual flow rate control is required to optimise accuracy when approaching the target set point weight.
"Batch Gain in Weight"
The feeder and hopper feed product onto a weigh platform, which is continuously weighed against a pre programmed accumulation of weight. Feeding ceases upon reaching the predetermined set point (g,kg,tonnes). Dual flow rate control is required to optimise accuracy when approaching the target set point weight. In-flight compensation is required to ensure over filling does not occur.
