The problem of swarf management is a familiar one and in the case of precious metals the constraints are even greater than for standard materials. With the value of gold at more than 42,000 CHF per kilo and maximum waste tolerance at no more than 2 per cent, producers are having to find ever more sophisticated solutions to recover as much of the material as possible to avoid paying for “waste”.
While swarf management is by no means a source of value added in production runs, the operation can quickly become costly and fraught with problems. Rimann SA specialises in supplying global solutions for recovering precious metals, notably for the watchmaking sector.
What about the swarf? The global solution that Rimann SA offers allows you to clean the swarf without using solvents, which always present a hazard for operator health, and without using inflammable products, which are an explosion hazard. The process begins with conventional centrifuging, after which the swarf is washed in detergent in a closed circuit. The swarf is then dried. The net weight of the precious metal is recovered. Rimann offers a complete, fully integrated system for centrifuging and washing. The centrifuging time can be set using a timer and is identical to the time for rinsing, which can follow on like a second process. The “oil” recipient is monitored by means of a probe to prevent it overflowing: if it is full, the centrifuge stops. Ease-of-use and reliable operation are guaranteed. The type of centrifuging and washing depends on the quantity and type of swarf to be processed. Numerous parameters need to be taken into account and Rimann is a partner of choice when it comes to swarf management.
But swarf management is only one part, there is also added value in every other aspect of "post-production" processes… We will deepen these aspects in our next issue.
