HIGH-PRECISIONAUTOMATIC DOSING MACHINE TO DOSE METAL GRAINS

T-DOSING™

FOR THE HIGHEST ACCURACY

T-Dosing™ is an industrial machine employed in the precious metals field to automate the weighing of grains used to produce ingots; this is one of the most delicate steps of the process.  Weight accuracy is fundamental for investment ingots, since an underweight ingot cannot be marketed and an overweight ingot would imply an evident gain loss for the manufacturer.
  
A machine weighing gold and silver grains with accuracy down to the milligram level is not only a tool, but also an actual guarantee. Even more so if all the dosing machine activities are monitored and recorded by an optional integrated computer system (Jarvis). 

Prior to casting, weighing accuracy also allows optimizing working times and thus costs. Being able to produce ingots with the right weight avoids waste in a number of areas.

Taking into account how useful it can be in many refineries of different sizes, we wanted T-Dosing™ to be an automated dosing machine that could be connected to any type of casting furnace and could manage two different metals - gold and silver - without cross-contaminations.

THE PAST

CRITICAL ISSUES AND DISAVANTAGES OF THE TRADITIONAL SYSTEM

  • Manual dosing entails high risks of error and thus metal loss.
  • This process requires a lot of manual work.
  • Given the high probability of non-compliant weighing results, underweight ingots often need to be casted again.
  • Time is wasted to continuously adjust weight before and after casting.
  • Many ingots are produced with the wrong weight and must be casted again; this implies a waste of resources, time and staff work.

THE INNOVATION

THE ADVANTAGES OF AN AUTOMATED SOLUTION

  • It is possible to set a compliant weight range (minimum/maximum) in the T-Dosing™ machine.
  • In order to achieve an otherwise unattainable continuous production without any waste of time and with accuracy down to the centigram or milligram level (according to the machine version), it is sufficient to set the manufacturing recipe (or select a preset one).
  • The containers holding non-compliant weighted grains are automatically discarded and moved to designated recovery areas, in order to avoid casting ingots with the wrong weight.
  • No waste of time adjusting weight before and after casting, because the load cell is extremely accurate.
  • The number of compliant ingot production is very high; the number of recasting is reduced to a minimum, thus optimizing costs and resources.

HOW DOES

THE T-DOSING™ AUTOMATIC DOSING MACHINE WORK?

The grains, properly sorted by diameter, are loaded in the respective hoppers. They are then funneled into vibrating channels leading to the first hopper, in which the macro weighing occurs. The flow rate of grains (higher for big-diameter grains, lower for small-diameter grains) decreases as the target weight is being approached.

Once 98-99% of target weight has being reached, grains are transferred into a specific empty container located on the analytical load cell which detects the exact missing weight, compensating it automatically by a wire-cut system. All containers outside the tolerance range as set by operators are discarded from the process line.

TAILORED AUTOMATION

AUTOMATION FOR THE HIGHEST ACCURACY

Each Tera Automation machine can be conceived as part of a modular line which can be combined according to the company's needs and facility space. Each machine can be fitted to existing machines and a full line can be developed over time.

T-Dosing™ was designed to perform an extremely accurate dosing - with a thousandth of a gram accuracy - of precious metals used for casting and may be combined with other machines, according to each operator's particular needs.
