SMI Dross Processing in Aluminum Recycling Operations

Since 2009, Mr. David Roth has been our head consultant and market manager of our equipment. He is very familiar with USA and Europe markets.
We have been supplying the highest quality dross pans to the aluminum industry for over 25 years. All of the major players in aluminum melting and casting have purchased our quality castings.

Based on Mr. Dave’s knowledge of customer operation, the unique characteristic of our dross pan design allows for a significant degree of cooling contact between the dross and cast steel. The number of holes and the double counter sink design allows for the maximum drain possible, without dross sticking in these holes. The distance between the skim and sow mold is looked at closely to allow large drain volumes without the pans freezing together.

The cooling cycle for these pans will be approximately two hours before the material can be rotated out of the pans. The large pan mass is critical to this result.

Some customers’ original use of the press were failure for two reasons. First there were not enough presses for an operation of the size. If a dross pan sets for more than 15 minutes with the type and temperature of dross the cooling and plating action that is the main benefit of pressing will not be achievable. The operators become frustrated at not seeing results when several pans are stacked up in front of a press and they are processing cold materials without results. In simple terms they stop doing what they see as a waste of time in their busy day. This was evident in your first efforts at pressing. The same failure would occur this time around if you purchase only one press per location as in our customers’ tender request. For this reason, we are respectfully quoting two presses per location. With one press, you will achieve the same results of your last experience at his technology.

The design and volume of our pans and press head will ensure the fastest cooling, highest drain and significant plating action of the pressed dross possible. We have designed them specifically to your furnaces, dross volumes and fork truck capabilities. Some Tardis pans were a very poor design. The had one hole for draining that always plugged up because of its configuration. The single chamber pan volume did not support cooling or the best plating action possible when pressing.
The most important part of the pressing process is the casting design of the pan and head. We focus on aluminum plant equipment and providing a high quality, simple low maintenance press to utilize the castings.
