Microprocessor control of devices systems of pneumatic container delivery for the analysis of samples of concentrating and metallurgical production

摘要

It is well known that automatic control of any process implies continuous or infrequent monitoring process parameters. At the ore dressing mills and metallurgical plants, such parameters may include composition of feedstock, fluxes, reagents, intermediate products, final tailings and wastewater. Usually, this information is supplied by the automated analytical monitoring system (AAMS), in which the main component is the automated sub-system for sampling and representative test sample transportation. This paper is dedicated to current issues regarding optimization of the microprocessor-based control system by the use of robotic mechanisms and devices in the pneumatic test sample capsule transportation facility and computer-aided modelling. The article describes a functional scheme of the pneumatic conveying system. Here, control signals are optimized, the algorithms and schemes of universal microprocessor of controlled system are outlined.
