Greensand to Core Room Sand Reclamation

Del Sol has been working on process details for taking greensand and returning it to your core room for re-use for cold box and no bake core making and molding operations.  There have been systems in the past that said they could accomplish this and they all seem to have fallen a little short.  Del Sol has developed a method that we believe will work and we are looking for foundries where this may be of interest.

What we would need from you is

• The number or tons per hour to process or the number truckloads of new sand delivered per day. 
• The total clay percentage present in your greensand
• Your gas rate per Mbtu
• Your electric rate / kwh
• Your new sand cost
• Your sand disposal cost
• You maintenance technician hourly rate

With this information, we can properly size a system for you and run a financial analysis to see if the process makes sense for your operation.  If it does, we can trial your sand in the actual equipment to be used for the process, and give you the result of the testing for use in your core room.  We want to prove results prior to taking an order.

We are looking for foundries that are serious about closing the supply loop on their sand and drastically reducing their new sand purchases and disposal costs.  Initially, this system was developed to coincide with our Carbo Ceramics non-silica product offering.  However, we believe this process can cost justify even with silica sand but we need your requirements to find out.

If you are interested, please call Lee White - Del Sol Industrial Services, Inc. at 830-237-7760 or email at lwhite@delsolservices.com

We look forward to the challenge.
