Mining in Frankston

Our analysers are particularly suited to high-scale and high temperate applications as seen in the alumina and nickel industries. The service we receive from pla is second to none precision light & air is an instrumentation manufacturer specialising in process analysers such as the smartdiver (muddiver).

The continuous measurement of clarity, interface, mud, compressed mud and tank profiles are key parameters for efficient CAD and settler control. The use of Smartdivers has proven to be critical for process optimization especially in the global metals minerals and mining industries. For the beginning time in the history of the alumina industry, a single Smartdiver was used to accurately and reliably track these key measurements during begin up of a newly modified settler in a USA refinery. The trends lower reflect a tank flare and the following variations during the upset. The aptitude to track and monitor these parameters proved indispensable in stabilizing the flaring vessel while optimizing flocculants addition. There were no flow or density measurements, resulting in operators relying exclusively on Smartdiver to control underflow solids based on compact bed level measurements. 5 ways to improve the field sampling process to better correlate field instruments data vs laboratory results.

Inline slurry liquor density analysis designed specifically for the alumina industry, and other industrial processes with aggressive slurry content. Spontaneous emulsion oversee station manufactured specifically for lengthy wall coal mining industry. The SmartDiver system was installed to produce measurements of clarity, hindered interface smooth and mud slick as well as density trends of the compacting mud layer, allowing the thickener oversee strategy to be enhanced dramatically. By monitoring the two autonomous layers of interface and mud, reliable process data was provided for: Thickener operational down time was reduced. The beginning process that was automated on the thickener was the discharge rate of the underflow pump system to maintain the dense slurry compact bed at the optimum smooth in the thickener. As a process analyses company operating in minerals processing environments, the reference old to check and calibrate our instruments accuracy is the field or process laboratory. What often lets everyone down and reduces the correlation between the field instrument measurements and the lab results is the sampling method. The lab and the field instrument are trending together. The above is my two cents worth from the field perspective on improving the sample taking process to ensure samples are representative and a closer correlation field instrument measurements vs lab results can be achieved. The consecutive measurement of clarity, interface, mud, compressed mud and tank profiles are key parameters for efficient CAD and settler control. As you change feed and flocculation regime, these levels, just like your interface and mud, will move around providing additional measurements for control. Precision Light and Air will be promoting its process analyses designed specifically for the minerals processing sector including: Precision Light and Air will showcase the Scholarly Diver, a ruggedised mud diver that provides measurement of mud levels, settling zones and overflow clarity in thickeners, clarifies, washers and decanters. Tank profiling (suspended solids vs depth) is also provided, as it is specific gravity profiling and bed glossy measurement. The device provides the operator with more operational parameters to oversee the thickener performance (clarity, interface, mud bed heights). The system allows the operator to identify changes in the conditions in the thickener through integrated DC alarms, trends of the various solid levels and tank profiles. Accurate blending of emulsions have a direct effect on the productivity and profitability of many mining and industrial operations. Operation of the SmartDose system is initiated by tall and low sensors in the bulk emulsion tank. Measures density of the liquor phase of a slurry self-reliant of suspended solids or mud. Is installed directly in the process piping or side stream. We implement and maintain a flow velocity overhead 1.5 meters per second and we do not experience scaling on any installation. Now, with the ALDCIK AC analyses, you can get an accurate, unchanging and repeatable measurement of conductivity in any process line size, with almost any velocity. Three methods probe installations are available to suit your specific application.
